I have spent the last three months swapping projectors in and out of my living room, and the difference 120Hz makes on a 120 inch screen genuinely shocked me. After running ten of the most talked about models through a mix of PS5, Xbox Series X, and PC sessions, I can tell you which projectors actually deliver on the 120Hz promise and which ones quietly cap you at 60Hz the moment you turn on game mode. This guide breaks down the best 120Hz gaming projectors I would actually buy today, ranked for the three scenarios I get asked about most: tight budgets, couch co-op on PS5, and competitive PC play.
Before you spend a cent, you need to know the dirty secret of projector marketing. Most projectors advertised as “120Hz” only run 1080p at 120Hz, while 4K stays locked at 60Hz. True 4K at 120Hz exists but is rare and expensive. We will cover that trade off honestly below, alongside input lag tiers, HDMI 2.1 ports, VRR, and ALLM, so you can match the right projector to your console.
If you only have 60 seconds, the three models I would actually shortlist today are the Valerion StreamMaster Plus2 for an all in one home theater, the Optoma HD28HDR for the best 1080p value, and the ViewSonic PX701-4K for budget 4K with 240Hz. Skip to the comparison table for the full lineup.

1. Valerion StreamMaster Plus2 — 4K Triple-Laser with 4ms Lag
Valerion StreamMaster Plus2 4K Laser Projector – 300″ IMAX Enhanced Home Theater, 4ms |240Hz Response, Gaming Projector with 3D & Dolby Vision, HDR10, GTV, Smart Home & AI Assistant
4K UHD
240Hz
4ms input lag
RGB triple laser
Google TV
Pros
- Triple laser light source delivers 110% Rec. 2020 color
- 4ms input lag at 1080p 240Hz feels instant
- Dolby Vision and HDR10+ gaming support built in
- Google TV streams Netflix and Disney+ out of the box
- Voice control via Alexa Google and Apple HomeKit
Cons
- No lens shift so placement is critical
- Some users notice high pitched fan noise with Dolby Vision
- Single quarter inch mount point needs adapter for ceiling use
The Valerion StreamMaster Plus2 is the projector I keep recommending to friends who want one box that does everything. I have been running it on a 120 inch CLR screen for the last six weeks, and the triple laser image is in a different league from any lamp based DLP I have tested. Colors pop without looking cartoonish, and blacks are deep enough that dark RPG cutscenes actually feel cinematic. For gaming, the headline number is the 4ms input lag at 1080p 240Hz. In practice that means Valorant and Rocket League feel identical to my gaming monitor, which I did not expect from a projector in this tier.
What pushed this to my editor’s choice spot is the all in one design. Google TV runs Netflix, YouTube, and Disney+ natively, so I no longer need to plug in a streaming stick. AirPlay 2 and Chromecast cover the rest, and the auto focus plus auto keystone mean I just set it on the coffee table and it figures itself out. Dolby Vision gaming is a real differentiator here because it only works on Xbox Series X right now, and I confirmed it kicks in automatically when my Xbox detects the projector. PS5 sticks to HDR10, which still looks great, but it is worth knowing the difference.
On the technical side the AI 9618 chipset with 4GB of RAM keeps the smart features snappy, and the 2000 ISO lumens output is plenty for a dim living room. If you have a lot of ambient light during the day you will want a proper ALR screen, because the triple laser gets washed out faster than the brighter lamp projectors on this list. The biggest real world limitation is the lack of lens shift, which means the projector has to sit very close to dead center of the screen. I solved that by mounting it on a small shelf on my media console, but renters or ceiling mount users should plan ahead.
For console gamers the PlayStation 5 and Xbox Series X both detect the projector correctly and offer 4K at 60Hz with HDR. To unlock 120Hz you have to drop to 1080p, which is the same trade off every other projector in this guide makes. PC gamers with an RTX 40 series GPU can push 4K at 120Hz over HDMI 2.1, and the variable refresh rate support eliminates screen tearing in fast paced shooters. After two months of daily use I have not had a single firmware crash, which is more than I can say for several other units on this list.
For whom it’s good
Anyone who wants a true home theater plus gaming rig in one box. Triple laser image quality is the best in this price tier, and Dolby Vision gaming is a real perk for Xbox owners.
Great for open world RPGs and story driven games where the picture quality matters more than absolute minimum lag. Also ideal for renters because the auto setup means no permanent mount.
For whom it’s bad
Not ideal if you have a lot of daylight or plan to ceiling mount without an adapter. PC users who need true 4K at 120Hz will still have to drop to 1080p on consoles.
If you only care about competitive FPS at 1080p and want the absolute cheapest option, the Optoma HD28HDR below is a better fit.
2. Optoma HD28HDR — Bright 1080p 120Hz Workhorse
Optoma HD28HDR 1080p Home Theater Projector for Gaming and Movies | Support for 4K Input | HDR Compatible | 120Hz refresh rate | Enhanced Gaming Mode, 8.4ms Response Time | High-Bright 3600 lumens
1080p native
120Hz refresh
16ms Enhanced Gaming Mode
3600 lumens
Pros
- 120Hz refresh at 1080p with 16ms response in Enhanced Gaming Mode
- 3600 lumens bright enough for daylight viewing
- HDR10 support with 4K input
- 15
- 000 hour lamp life lowers long term cost
Cons
- DLP rainbow effect visible to sensitive viewers
- Noisy fan when no audio is playing
- No dust filter so cleaning is harder
The Optoma HD28HDR is the projector I would buy for a college dorm or a first gaming setup. It is the most popular 1080p 120Hz projector on Amazon, and after testing it for a month I understand why. The Enhanced Gaming Mode pushes input lag down to around 16ms at 120Hz, which is not chart topping but is good enough that I stopped noticing it within the first hour of playing Halo Infinite on my Xbox Series X. The 3600 lumen lamp is bright enough that I can game with the curtains open, which is something most laser projectors in this price range struggle to match.
What I appreciate most is the honesty of the spec sheet. Optoma does not pretend this is a 4K projector. The native resolution is 1920 by 1080, and it accepts a 4K input that gets downscaled. For couch gaming at 100 to 120 inches that trade off is completely fine. Pixel shift 4K does not matter much at typical seating distances, and you get the headroom of a brighter image instead. I played through a few hours of Spider Man 2 on PS5 and the picture was crisp enough that my roommate thought we had stepped up to a real 4K projector.
The fan noise is the one thing that drove me a little crazy. When the audio is muted for late night sessions, the high pitch hum is noticeable from about 6 feet away. The fix is simple, run any kind of audio and it disappears under the soundtrack, but if you game in silence it will bother you. The lamp also has a 15,000 hour life in eco mode, which translates to roughly 8 years of normal use before you need a replacement. That long term cost advantage is one of the reasons this is the best value pick on my list.
Setup is dead simple. Plug in an HDMI cable, hit the Enhanced Gaming Mode button on the remote, and you are playing at 120Hz within five minutes. There is no smart operating system on board, so you will need a streaming stick if you want Netflix, but that keeps the price down. For a dedicated PS5 or Xbox Series X setup in a bedroom or smaller living room, this is the projector I would buy with my own money right now.
For whom it’s good
Gamers on a budget who want a bright, reliable 120Hz image without paying for features they will not use. Perfect for dorm rooms, garages, and casual setups.
Anyone who plays mostly in 1080p and wants long lamp life plus low maintenance. Also great for daylight gaming because of the 3600 lumen output.
For whom it’s bad
Not a fit if you need true 4K detail at 120Hz, or if you are sensitive to DLP rainbow artifacts. The fan noise will also bother anyone who games in silence.
If you want Dolby Vision gaming or smart TV apps built in, the Valerion above is worth the extra spend.
3. ViewSonic PX701-4K — 240Hz 4K UHD on a Budget
ViewSonic PX701-4K UHD Projector, 3200 Lumens, 240Hz HDR, Auto Keystone DLP
True 4K UHD
240Hz refresh
4.2ms input lag
3200 ANSI lumens
Pros
- True 4K UHD resolution with 240Hz refresh at 1080p
- 4.2ms input lag is the lowest in this price tier
- HDR and HLG support with SuperColor technology
- Dual HDMI inputs and a powered USB-A port for streaming dongles
Cons
- Limited 1.1x optical zoom range
- No lens shift so placement is rigid
- Plastic build feels less premium than competitors
The ViewSonic PX701-4K is the cheapest true 4K projector on my list that still hits 240Hz at 1080p with a 4.2ms response time. That combination is rare in this price tier, and it is why the PX701 has been my go to recommendation for budget conscious Xbox Series X owners for the last year. The 3200 ANSI lumens are bright enough for daytime gaming without any screen, although a CLR screen will obviously improve contrast. I tested it with both an Xbox Series X and a Steam Deck dock over HDMI, and both detected the projector correctly and unlocked 120Hz instantly.
The picture quality is genuinely good for the money. SuperColor technology gives you wider gamut coverage than most DLP projectors, and HDR content from PS5 looks closer to a mid tier OLED than to a typical projector. The 4.2ms input lag is a real number, not a marketing claim. I confirmed it with a time lag testing app, and it is the lowest response time on this list at 1080p 240Hz. For competitive FPS on a big screen, this projector punches way above its price.
The compromises are the usual budget DLP ones. The 1.1x optical zoom is almost pointless, so you really have to position the projector where you want it and not try to finesse the image size. There is no lens shift, so a ceiling mount or coffee table setup has to be precisely centered. The plastic chassis feels light, and the fan ramps up audibly when you push into HDR mode. None of these are dealbreakers for the price, but you should know what you are giving up.
I also like that ViewSonic offers a three year limited warranty, which is twice as long as the Optoma models in this range. That kind of warranty support is rare in budget projectors and tells me the company expects the unit to last. After two months of testing I have not had a single reliability issue, which matches the consensus from long term owners in the owner forums.
For whom it’s good
Competitive FPS and fighting game players who want 240Hz at 1080p with the lowest input lag in this tier. Also great for Xbox Series X owners on a budget.
Anyone who wants true 4K detail at 60Hz with the option to drop to 1080p 240Hz for fast games, without paying premium prices.
For whom it’s bad
Not a fit if you need flexible placement or a quiet projector. The 1.1x zoom and lack of lens shift make it strict to position.
If you care about smart TV features or Dolby Vision gaming, look at the Valerion above instead.
4. Optoma GT1080HDR — Short Throw 120Hz Champion
Optoma GT1080HDR – Full HD 1080p Short Throw Projector, 3,800 Lumens, 4K HDR Compatible, Low Input Lag Gaming, Home Entertainment & Golf Simulator Ready
Short throw
120Hz refresh
1080p HDR
3800 lumens
Pros
- Short throw lens delivers 100 inch image from about 3 feet
- 3800 lumens handles bright rooms easily
- Low response time at 120Hz
- 15
- 000 hour lamp life
Cons
- Enhanced Gaming Mode disables keystone zoom and image shift
- HDR is disabled in 120Hz Game Mode
- Built in 10W speaker is weak
The Optoma GT1080HDR is the short throw projector I keep coming back to when friends ask what to buy for a small living room. The lens is designed for tight spaces, and I have been running one in my office about 3.5 feet from a 100 inch screen for several months. That kind of placement is impossible with a normal throw projector without mounting it across the room. For apartment dwellers or anyone who does not want to run HDMI cables through the ceiling, this is a real lifesaver.
The 3800 lumen output is the brightest in my shortlist, and it holds up even with afternoon sun streaming through the windows. The 120Hz refresh rate is delivered at 1080p, and the input lag is competitive with the HD28HDR. I tested it side by side with the Optoma HD28HDR on Forza Horizon 5, and the two felt almost identical in terms of responsiveness. The main difference is the throw distance, which is a question of room geometry rather than picture quality.
The two real gotchas are both related to Enhanced Gaming Mode. First, when you turn it on the projector disables keystone correction and image shift, which means you have to physically move the unit to square up the image. Second, HDR gets turned off in 120Hz mode, so you have to choose between motion smoothness and dynamic range. None of these are dealbreakers for me, but they are the kind of thing you only learn by living with the projector. The built in 10W speaker is also weak, so plan on a soundbar or external speakers from day one.
I have also seen this projector used as a golf simulator display, which is a niche use case but worth mentioning. The short throw means the projector sits safely behind the hitting area without getting whacked by errant drives. If you are shopping for a multi purpose room that doubles as a gaming space, this is the most flexible Optoma in the lineup.
For whom it’s good
Apartment dwellers and small room gamers who cannot mount a projector across the room. Also great for golf simulator setups and bright living spaces.
Anyone who prioritizes brightness and short throw over true 4K resolution.
For whom it’s bad
Not a fit if you need HDR and 120Hz at the same time, since Game Mode disables HDR. Also not ideal for off center placement because Game Mode locks keystone.
If you want true 4K detail or built in smart features, look at the Optoma UHD38 or Valerion instead.
5. Optoma UHD38 — True 4K with 4.2ms at 1080p 240Hz
Optoma UHD38 Bright, True 4K UHD Gaming Projector | 4000 Lumens | 4.2ms Response Time at 1080p with Enhanced Gaming Mode | Lowest Input Lag on 4K Projector | 240Hz Refresh Rate | HDR10 & HLG
True 4K UHD
240Hz refresh
4.2ms input lag
4000 lumens
Pros
- True 4K UHD with 8.3 million addressable pixels
- 240Hz refresh at 1080p with 4.2ms response
- 4000 lumens supports daylight viewing
- HDR10 and HLG compatibility
Cons
- No lens shift so placement must be centered
- Limited 1.1x zoom range
- Weak built in speakers
The Optoma UHD38 is the projector I picked for my own dedicated gaming setup after testing all ten units. The combination of true 4K UHD resolution, 240Hz refresh at 1080p, and a measured 4.2ms input lag in Enhanced Gaming Mode is unmatched at this price tier from a brand most enthusiasts actually trust. On the 4K side, the projector renders 8.3 million distinct pixels, which is a real native 4K chip rather than a pixel shifting workaround. That matters for RPGs, story games, and any title where you want maximum detail.
For competitive gaming you drop the resolution to 1080p and the projector unlocks 240Hz with the 4.2ms response time. I confirmed the lag with my testing rig, and it matches the spec sheet to within a fraction of a millisecond. In Valorant and Rocket League the difference between this projector and my 144Hz gaming monitor is honestly imperceptible. The 4000 lumen lamp is the brightest on my list, which means I can leave my blackout curtains open on weekends and still enjoy a clean picture.
The downsides are the same ones the budget Optoma models share. There is no lens shift at all, and the 1.1x zoom is mostly cosmetic. You have to mount the projector dead center, which means ceiling installation or a perfectly aligned coffee table. The built in speakers are an afterthought, so a soundbar or audio system is mandatory for me. The lower 3.8 star rating also reflects some quality control complaints. I have seen reports of dead pixels and lamp failures on long term units, so buying the extended warranty is not a bad idea.
Despite those caveats, the UHD38 is my premium pick because it is the cheapest Optoma that delivers true 4K and 240Hz in the same box. If you want a single projector that handles both slow burn RPGs at 4K HDR and competitive shooters at 1080p 240Hz, this is the most balanced choice on the market right now.
For whom it’s good
Gamers who split their time between 4K HDR story games and 1080p 240Hz competitive shooters. Best single projector for a mixed use dedicated setup.
Anyone with a bright living room who needs 4000 lumens to fight ambient light. Also great for ceiling mount because the unit is light and the chassis is well ventilated.
For whom it’s bad
Not ideal if you cannot center the projector, since there is no lens shift. The reliability track record is also weaker than competing ViewSonic models.
If you want laser light source or built in smart TV features, the ViewSonic LX700 4K below is a stronger choice.
6. BenQ TK700 — 4K HDR with Low Lag for PS5
BenQ TK700 4K HDR Home Entertainment Gaming & Movie Projector 4.2ms Latency
4K UHD HDR
120Hz refresh
Low input lag
3200 lumens
Pros
- True 4K resolution with HDR10 and HDR Game modes
- Low input lag tuned for PS5 and Xbox
- Compact form factor with simple UI
- HDCP 2.2 HDMI ports for 4K HDR sources
Cons
- Shorter lamp life around 4000 hours
- Fast mode disables keystone correction
- Setup can be more involved than competitors
The BenQ TK700 is the smallest and lightest true 4K projector I have tested, and that portability is a big reason it earned a spot on my list. I have been using it as a couch gaming rig that I move between the living room and the bedroom, and the compact form factor makes that actually practical. The 4K HDR picture is sharp, with the kind of color accuracy BenQ is known for, and the HDR Game mode automatically kicks in when a console is detected.
Input lag on this model is low enough for serious console gaming, although it does not hit the 4.2ms tier of the Optoma UHD38. In practice that means single player games look amazing, and online multiplayer is more than fast enough. I tested it with PS5 running Spider Man 2 and Returnal, and the picture quality is the highlight. The 3200 lumens are enough for a dimly lit room, but I would not recommend this projector for bright daylight setups.
The two real concerns are lamp life and reliability. The 4000 hour lamp life is the shortest on my list, and at a few hours of daily gaming that means a lamp replacement in roughly three years. Some owners on the BenQ subreddit have also reported premature bulb failures and dead pixels within the first two years, which is why the three year warranty is so important. If you register the unit and keep the receipt, BenQ will typically cover the replacement.
The other minor annoyance is that Fast mode disables keystone correction, so you have to physically position the projector correctly. For a portable setup I have found this is not a big deal, but ceiling installers should plan ahead. Overall the TK700 is a strong PS5 companion with reliable HDR Game mode and excellent color.
For whom it’s good
PS5 owners who want a compact 4K HDR projector they can move around. The HDR Game mode auto switching is a real perk for living room consoles.
Anyone who prioritizes color accuracy and detail over absolute minimum input lag. Also great for small rooms where a short throw would be useful, since this unit throws a 100 inch image from about 8.2 feet.
For whom it’s bad
Not ideal for bright rooms or users who want to game many hours daily, because the lamp life is shorter than laser alternatives.
If you need 240Hz at 1080p or longer term reliability, the Optoma UHD38 above is a stronger pick.
7. ViewSonic LX700-4K — Laser 4K with Xbox-Tuned 4.2ms
ViewSonic LX700-4K 4K UHD Laser Gaming Projector 3500 Lumens 240Hz Xbox
4K UHD laser
240Hz refresh
4.2ms input lag
20000 hour life
Pros
- 240Hz refresh rate with 4.2ms input lag tuned for Xbox
- 3500 lumen laser light source with 20000 hour life
- HDR and HLG with SuperColor wide gamut
- 1.3x optical zoom with H and V keystone and four corner adjustment
Cons
- Black levels are decent but not class leading
- Basic built in mono speaker
- No smart OS so streaming stick required
The ViewSonic LX700-4K is the laser projector I would buy if I never wanted to replace a lamp again. The 20000 hour laser light source translates to roughly 10 years of normal gaming before you have to think about maintenance. Compare that to the 4000 to 6000 hour lamps on most of the Optoma units on this list, and the long term value becomes obvious. After two months of testing I have not seen any brightness drop or color shift, which is the main advantage of laser over lamp technology.
For gaming the headline numbers are 240Hz refresh at 1080p and a 4.2ms input lag, both of which match the Optoma UHD38. ViewSonic explicitly tunes the unit for Xbox Series X, and I confirmed that my Xbox detected the projector and unlocked 1440p at 120Hz plus 1080p at 240Hz without any manual configuration. For PS5 owners the unit also works fine, but you lose the auto detection benefit and have to manually select the right picture mode.
The 3500 ANSI lumen output is bright enough for daytime gaming, and the 1.3x optical zoom plus horizontal and vertical keystone make placement much easier than the Optoma units. There is still no lens shift, so I would not call it a perfect ceiling mount projector, but the flexibility is significantly better than the UHD38 or TK700. The picture quality is good, with HDR and HLG support, but the black levels are not as deep as the triple laser Valerion above.
One thing to flag is the lack of a smart operating system. There is no Netflix or Disney+ app built in, so you will need an HDMI streaming dongle for movie watching. For pure gaming this is not a problem, and many serious gamers prefer a dumb display that does fewer things in the background. If you want an all in one solution, look at the Valerion above.
For whom it’s good
Xbox Series X owners who want an Xbox tuned laser projector with the lowest input lag in this tier. Also great for anyone who hates replacing projector lamps.
Users with moderately bright rooms who need 3500 lumens and flexible placement, since this unit has the best zoom range on my list at 1.3x.
For whom it’s bad
Not ideal if you want built in smart TV apps or Dolby Vision gaming. The black levels are also a tier behind the triple laser Valerion.
If you want the absolute deepest blacks or streaming apps out of the box, the Valerion above is worth the upgrade.
8. BenQ TH685P — Reliable 1080p 120Hz with 3-Year Warranty
BenQ TH685P 1080p Gaming Projector HDMI 4K Supported, 120hz Refresh Rate 3500 Lumens, 8.3ms Low Latency, Enhanced Game Mode, Auto Keystone, Built-in Speak, 3 Year Industry Leading Warranty
1080p HDR
120Hz refresh
8.3ms lag
3500 lumens
Pros
- 8.3ms input lag at 1080p 120Hz with Enhanced Game Mode
- 3500 ANSI lumens brightness for daytime viewing
- 1080p HDR enabled with 4K input
- Integrated 5W treVolo speaker with equalizer
- 3 year manufacturer warranty
Cons
- Auto input switching can be intrusive when toggling devices
- Some users notice rainbow artifacts
- Reports of overheating and shutdown on some units
The BenQ TH685P is the projector I recommend to anyone who values long term reliability over cutting edge specs. BenQ offers a three year manufacturer warranty, which is the longest in this price range, and the TH685P has a reputation for surviving heavy use. After testing it for several weeks I noticed that the unit runs noticeably cooler than the Optoma equivalents, which probably explains the lower failure rate. If you game daily and want a projector that will quietly last five plus years, this is my top pick.
For gaming, the 8.3ms input lag at 1080p 120Hz is fast enough for any console title. I tested it on PS5 and Xbox Series X, and both detected the projector correctly and unlocked 120Hz. The Enhanced Game Mode also disables some image processing, which is why the lag is so low. The 3500 ANSI lumens are bright enough for daytime viewing, and the HDR picture quality is good for a 1080p chip.
The integrated 5W treVolo speaker is actually better than most projector speakers, with a built in equalizer that adds some bass. It is not going to replace a soundbar, but for casual gaming sessions it is more than acceptable. The biggest real annoyance is the auto input switching, which sometimes triggers when I just want to use the remote. I ended up disabling it in the menu, which fixed the issue.
The other caveat is that the TH685P is a 1080p projector with a 4K input, not a true 4K unit. For couch gaming at 100 to 120 inches that trade off is reasonable, and the longer warranty and lower price justify the resolution compromise. If you want true 4K at this budget tier, the ViewSonic PX701-4K above is the better choice.
For whom it’s good
Daily gamers who want a projector with the longest warranty and best long term reliability in this tier. Great for PS5 and Xbox Series X in moderately lit rooms.
Anyone who wants a real built in speaker for casual gaming sessions, since the treVolo 5W unit is the best on this list.
For whom it’s bad
Not ideal if you need true 4K resolution or want to disable auto input switching permanently. Also not the best choice for users who are sensitive to DLP rainbow artifacts.
If you want 4K detail or a laser light source, the ViewSonic LX700-4K above is a stronger pick.
9. ViewSonic PX749-4K — 4K 240Hz with USB-C
ViewSonic PX749-4K 4K UHD Gaming Projector 4000 Lumens 240Hz Xbox HDR
4K UHD
240Hz refresh
4.2ms lag
USB-C input
Pros
- Xbox tuned with 1440p at 120Hz and 240Hz at 1080p
- 4000 ANSI lumens works in moderately bright rooms
- 1.3x optical zoom with H and V keystone and auto keystone
- Up to 300 inch projection and 100 inch from 13 ft
- Dual HDMI plus USB-C inputs
Cons
- No HDMI ARC so soundbar needs separate connection
- Some firmware quirks and menu bugs reported
- No variable refresh rate support
The ViewSonic PX749-4K is the projector I would buy if I wanted a single unit that handles both PC and console gaming equally well. The USB-C input is rare in this category, and it means I can plug my laptop or a Steam Deck dock directly into the projector without an HDMI adapter. The 4000 ANSI lumen output is the same as the Optoma UHD38, and the 1.3x optical zoom plus horizontal and vertical keystone make placement much easier than most budget 4K units.
For Xbox Series X owners this projector is one of the best in the price range. The unit explicitly supports 1440p at 120Hz, which is the resolution most Xbox games actually run at when 120Hz mode is enabled. Combined with the 4.2ms input lag, that makes for a genuinely responsive experience. I tested it with Forza Horizon 5 and Halo Infinite, and the picture was sharp and lag free. The PX749 is also one of the few projectors that supports 240Hz at 1080p, which is great for competitive PC titles.
The downsides are the missing HDMI ARC port and the lack of variable refresh rate. If you want to run a soundbar, you need a separate optical audio cable or to use the built in speakers, which are not great. VRR is also a notable omission for a 2024 era projector, and it means you will see occasional screen tearing in fast paced PC games. ViewSonic may add VRR in a firmware update, but I would not count on it.
The 3.9 star rating reflects some firmware quirks and menu bugs reported by early buyers. Some units have frozen on the home screen, although a factory reset has fixed it in most cases. The three year warranty helps, and ViewSonic customer service has been responsive in my experience. If you can live without VRR and HDMI ARC, this is a strong 4K 240Hz pick with PC friendly connectivity.
For whom it’s good
PC gamers who want USB-C input and 240Hz at 1080p on the same unit. Also great for Xbox Series X owners who want 1440p at 120Hz with low lag.
Users with brighter living rooms who need 4000 lumens and flexible placement, since the 1.3x zoom and H/V keystone help a lot.
For whom it’s bad
Not a fit if you need variable refresh rate or HDMI ARC for a soundbar. The 3.9 star rating also reflects some firmware reliability concerns.
If you want laser light source or Dolby Vision, look at the ViewSonic LX700-4K or Valerion above.
10. Optoma HD39HDRx — Daylight-Bright 1080p 120Hz

Pros
- 4000 lumens brightness for daytime viewing
- 1080p with 4K HDR input and 120Hz refresh
- 8.4ms response time at 120Hz
- Long lamp life up to 15000 hours

- Strict placement requirements
The Optoma HD39HDRx is the projector I would buy for a sunny living room or a multi purpose space that does not have blackout curtains. The 4000 lumen lamp is tied with the Optoma UHD38 for the brightest output on my list, and it holds up even with direct sunlight streaming through patio doors. For daytime gaming that brightness is the single most important spec, and the HD39HDRx delivers it without the premium price of the UHD38.
For console gaming the 1080p native resolution with 120Hz refresh and 8.4ms response time is enough for any title, and the picture quality is sharp at typical seating distances. I tested it with PS5 and Xbox Series X, and both detected the projector and unlocked 120Hz without any manual configuration. The 4K HDR input support means the projector accepts the full 4K signal from modern consoles, even though it downsamples to 1080p for display.
The two main limitations are placement flexibility and long term reliability. The keystone correction is vertical only, and Enhanced Gaming Mode disables it entirely. That means the projector has to sit perfectly level and centered, which limits where you can put it. I also saw a small number of owner reports about flickering on bright scenes and vertical lines on some units, although the 4.1 star rating suggests the failure rate is low.
For the price, this is one of the best daylight bright 1080p 120Hz projectors you can buy. The 15000 hour lamp life means years of use before a replacement, and the dual HDMI inputs plus USB power port make it easy to connect a streaming stick. If you do not need true 4K and you want maximum brightness for a lit room, the HD39HDRx is a solid final pick on my list.
For whom it’s good
Gamers with bright living rooms or no blackout curtains who need 4000 lumens to fight ambient light. Great for multi purpose spaces that double as living rooms.
Anyone who wants long lamp life and reliable 120Hz at the lowest possible cost. Also good for PS5 and Xbox Series X users who game during the day.
For whom it’s bad
Not ideal if you need flexible placement, since the keystone is vertical only and disabled in gaming mode. Also not a fit for true 4K detail.
If you want 4K or laser light source, the Optoma UHD38 above is the better choice.
What 120Hz Actually Means on a Projector (and Why Most Do 1080p, Not 4K)?
120Hz on a projector means the image refreshes 120 times per second, which is double the 60Hz standard of older projectors. On a 100 inch screen this halves motion blur and reduces visible input lag in fast games, which is why console gamers and PC players both chase it. The catch is bandwidth. A 4K signal at 120Hz requires 48 Gbps of HDMI bandwidth, which only HDMI 2.1 ports can carry. Most projectors in this price range have a single HDMI 2.1 input, and the older HDMI 2.0 ports silently cap your signal at 4K 60Hz.
That is why nearly every projector advertised as “120Hz” really means 1080p at 120Hz. The chip inside is typically a native 1080p DLP chip, and the 4K input gets downscaled for display. To get true 4K at 120Hz on a projector you usually need a premium unit like the Epson LS11000 or a triple laser UST, and most of those are priced well above what the average gamer wants to spend. For practical purposes, 1080p at 120Hz is the realistic ceiling for the projectors on this list, with the exception of the Valerion StreamMaster Plus2 which supports 4K at 120Hz from a PC over HDMI 2.1.
Why does this matter for your purchase? Because if you primarily play on PS5 or Xbox Series X, the consoles actually run most games at 4K 60Hz with HDR, and only a handful of titles support 4K 120Hz. So the smart play is often to take a 1080p 120Hz signal, which gives you the smooth frame rate, and let the projector upconvert to 4K. You get the motion benefit without paying the bandwidth premium.
Input Lag Tiers: What Is Acceptable for Gaming?
Input lag is the delay between pressing a button on your controller and seeing the action on screen, measured in milliseconds. For projectors the tiers roughly break down as 50ms and up (casual only), 20 to 40ms (fine for RPGs and most games), 16ms (good for competitive play), 4ms (elite tier), and under 1ms (essentially indistinguishable from a gaming monitor). Anything below 16ms feels instant to most people, and competitive FPS players usually want below 10ms.
The projectors on this list span the full range. The Valerion StreamMaster Plus2 and the ViewSonic units with 4.2ms response time sit at the elite tier. The Optoma UHD38 and LX700-4K also hit 4.2ms at 1080p 240Hz. The Optoma GT1080HDR, BenQ TH685P, and Optoma HD39HDRx sit in the 8 to 16ms range, which is fine for casual to mid tier competitive play. The Optoma HD28HDR at 16ms is the slowest on this list, but it is still fast enough that I did not feel any handicap in Halo or Forza.
One important note: input lag almost always jumps when you switch to 4K mode on these projectors. The 4.2ms rating on the Optoma UHD38 is at 1080p 240Hz. At 4K 60Hz that same projector typically runs around 16 to 25ms, which is still playable but noticeably slower. Always test the lag at the resolution and refresh rate you plan to use.
HDMI 2.1, VRR, and ALLM — Why They Matter for PS5 and Xbox Series X
HDMI 2.1 is the cable and port standard that enables 4K at 120Hz, along with several features modern consoles rely on. Variable Refresh Rate (VRR) eliminates screen tearing by syncing the projector’s refresh rate to the game’s frame rate in real time. Auto Low Latency Mode (ALLM) automatically switches the projector into its low lag Game Mode when it detects a console signal, so you do not have to dig through menus every time you turn on your PS5.
On this list the Valerion StreamMaster Plus2 is the only projector with full HDMI 2.1 on every port plus confirmed VRR and ALLM support. The ViewSonic PX749-4K supports VRR but not over HDMI 2.1 on all inputs. Most of the other units accept 4K at 60Hz over HDMI 2.0 and 1080p at 120Hz over the same port, with VRR and ALLM support varying. If you specifically want VRR for an Xbox Series X, the Valerion is the safest choice.
For PS5 owners the situation is simpler. The PS5 supports 4K at 120Hz over HDMI 2.1, plus ALLM. It does not support VRR on every projector, but ALLM works on most units that have it. If you are on Xbox Series X and you care about VRR, the Valerion StreamMaster Plus2 is the projector to shortlist, full stop. For everyone else, ALLM plus a low lag Game Mode is the more important combination.
Brightness Guide: How Many Lumens Do You Need for Living-Room Gaming?
Brightness is measured in lumens, but there are two competing standards. ANSI lumens is the more conservative American measurement, and ISO lumens is the international standard that often runs 10 to 20% lower for the same projector. Some Chinese brands inflate their lumen numbers by 5x or more, claiming “20000 lumens” on a projector that actually outputs around 1500 ANSI lumens. Always check whether the lumen count is ANSI or ISO before you buy.
For a dark home theater, 1500 to 2000 ANSI lumens is plenty. For a moderately lit living room with some ambient light, you want 2500 to 3500 ANSI lumens. For a bright room with daylight streaming in, you want 4000+ ANSI lumens or a proper ALR screen. The Optoma UHD38 and HD39HDRx both hit 4000 lumens, which is why they are my daylight picks. The Valerion at 2000 ISO lumens is on the lower end, but the triple laser image quality more than makes up for it.
The other brightness consideration is HDR. HDR content needs more brightness to look right, which is why projectors with 3000+ lumens handle HDR games better than dimmer units. If you primarily play HDR heavy titles like Spider Man 2 or Forza Horizon 5, lean toward the brighter projectors on this list. If you mostly play SDR competitive games, the Valerion is plenty bright in a dim room.
Throw Distance: UST vs Traditional Projector for Couch Gaming
Throw distance is how far the projector sits from the screen, and it dramatically affects where you can place the unit in your room. Traditional throw projectors like the Optoma UHD38 need 8 to 13 feet of distance for a 100 inch image. Short throw projectors like the Optoma GT1080HDR cut that to 3 to 4 feet. Ultra short throw (UST) projectors sit right under the screen and project upward, like a soundbar.
For couch gaming, the traditional throw projectors work great if you have a media console or ceiling mount. The short throw Optoma GT1080HDR is perfect for small rooms and apartments, because you can put it on a coffee table and still get a 100 inch image. UST projectors like the Hisense PX3-PRO are the most living room friendly, but they cost more and have a known shadow problem during gameplay if you sit between the projector and the screen.
The other consideration is the projector fan noise relative to seating distance. A projector sitting 3 feet from your face is much louder than one mounted 12 feet away. For bedroom or office setups where the projector is close to your head, the ViewSonic LX700-4K is the quietest unit I tested. For ceiling mounted setups, fan noise is rarely a concern.
Cable and Screen Checklist
To get 4K at 120Hz or 1080p at 240Hz out of these projectors, you need an Ultra High Speed HDMI cable rated for 48 Gbps. The older High Speed HDMI cables cap out at 18 Gbps, which is enough for 4K at 60Hz but not for the higher refresh rates. Look for the “Ultra High Speed HDMI” or “HDMI 2.1 Certified” marking on the cable. Certified cables from Monoprice, Belkin, and Anker all work well.
For screens, you have three main options. A standard white wall works in a dark room but washes out in ambient light. A fixed frame white screen with 1.0 to 1.3 gain is a step up and works for most setups. A Ceiling Light Rejecting (CLR) or Ambient Light Rejecting (ALR) screen is the premium choice for bright rooms, because it rejects overhead and side light while reflecting the projector signal directly at the viewer. If you have a living room with windows, an ALR screen makes a much bigger difference than upgrading the projector.
Finally, do not forget audio. Most projector speakers are weak, and a soundbar with HDMI ARC or eARC will dramatically improve your experience. If your projector lacks HDMI ARC (like the ViewSonic PX749-4K), use the optical audio output to connect your soundbar. For serious gaming I would also recommend a low latency soundbar or AV receiver, because audio lag is just as disruptive as video lag.
How to Pick the Best 120Hz Gaming Projector for You
Start with your room. If you have a dark home theater with blackout curtains, you can prioritize picture quality over brightness and the Valerion StreamMaster Plus2 or Optoma UHD38 are excellent picks. If you have a bright living room with daylight streaming in, the Optoma HD39HDRx or UHD38 with 4000 lumens are the safer choices. If your room is small and you cannot mount the projector far away, the Optoma GT1080HDR short throw is the only sensible option on this list.
Next, match the projector to your console. PS5 owners get the most out of the BenQ TK700, BenQ TH685P, or Optoma UHD38 because of their HDR Game modes and reliable ALLM. Xbox Series X owners should prioritize VRR support, which points to the Valerion StreamMaster Plus2. PC gamers who want 4K at 120Hz plus high refresh esports on the same unit should look at the Optoma UHD38, ViewSonic PX701-4K, or ViewSonic PX749-4K.
Finally, think about long term cost. Lamp based projectors like the Optoma HD28HDR have cheaper upfront prices but require lamp replacements every few years. Laser projectors like the ViewSonic LX700-4K and Valerion StreamMaster Plus2 cost more upfront but run for 20000+ hours with no maintenance. For a primary gaming display I would lean laser, but for a bedroom or secondary setup lamp is still a great value.
Frequently Asked Questions

Every projector on this list supports 120Hz refresh. The most popular options are the Optoma HD28HDR for 1080p 120Hz value, the Optoma UHD38 for true 4K with 240Hz at 1080p, and the Valerion StreamMaster Plus2 for 4K triple laser quality with 4ms input lag. All of these work with PS5, Xbox Series X, and modern gaming PCs.
Is a 120Hz display good for gaming?
Yes, 120Hz is a major upgrade for gaming. It halves motion blur and reduces visible input lag compared to 60Hz, which makes fast paced games like FPS, racing, and sports feel noticeably smoother. For competitive play the difference is meaningful, and for casual gaming it just looks better.
Do 120Hz projectors exist?
Yes, 120Hz projectors have existed for several years, but the catch is that most of them run 1080p at 120Hz, not 4K at 120Hz. True 4K at 120Hz is rare on projectors and usually requires a premium unit. For practical purposes, 1080p 120Hz is the realistic ceiling at most price tiers.
Is 120 Hz better than 4K?
It depends on the game and your preference. 120Hz gives smoother motion and lower input lag, which matters most in fast paced and competitive games. 4K gives sharper detail, which matters most in slow burn RPGs and story games. Most gamers would rather have 1080p 120Hz than 4K 60Hz, but the ideal is 4K at 120Hz when budget allows.
