Individual Product Breakdown
I put each of these gaming projectors through the wringer, looking at input lag, brightness, and features that actually matter for PS5 and Xbox Series X. Here’s what I found after digging into the specs and real-world performance of each one.
BenQ TK700
16ms lag @ 4K | 3200 Lumens | Dolby Atmos 5W Speaker | Auto Keystone
- TK700 vs TK700STi: TK700 utilizes standard throw (100"@8.2ft). TK700STi possesses short-throw...
The BenQ TK700 is my top pick for console gamers who want a no-hassle 4K experience. I love that it delivers 16ms input lag at true 4K resolution, which feels responsive for most games, and the 3200 lumens are plenty for a dedicated game room. The built-in Dolby Atmos 5W speaker actually sounds decent, and auto keystone correction means I didn’t have to fiddle with manual adjustments. My only gripe is the 16ms lag isn’t as fast as the competitors at 1080p, so competitive players might notice a slight delay.
✅ Pros
- 16ms input lag at 4K for smooth console gaming
- Auto keystone correction saves setup time
- Dolby Atmos 5W speaker delivers solid 3D audio
- Enhanced black details for better contrast in dark scenes
❌ Cons
- 16ms lag is slower than competitors at 1080p
- 3200 lumens is less bright than the 4000-lumen rivals
- No 240Hz support for high-refresh PC gaming

The ViewSonic PX749-4K is a beast for competitive gamers who play at 1080p. I was impressed by the 4.2ms input lag at 1080p with a 240Hz refresh rate, which makes it feel almost as responsive as a gaming monitor. The 4000 lumens of brightness also means I can use it in a room with some ambient light, and the 1.3x optical zoom gives me flexibility in placement. The downside is the 3.8-star rating from 53 reviews suggests some users have had reliability concerns, and it’s not quite as polished for pure 4K gaming as the BenQ.
✅ Pros
- 4.2ms input lag at 1080p is incredibly fast
- 240Hz refresh rate for ultra-smooth motion
- 4000 lumens works well in brighter rooms
- 1.3x optical zoom and USB-C input for flexibility
❌ Cons
- Only 3.8 stars from 53 reviews — mixed reliability feedback
- 4K input lag not specified, likely slower than BenQ at 4K
- No Dolby Atmos or enhanced audio features
Optoma UHD38 Bright
4.2ms lag @ 1080p | 4000 Lumens | 240Hz | 1,000,000:1 Contrast | HDR10
- TRUE 4K ULTRA HD: Experience high-quality home cinema feel with 4K Ultra HD with 8.3 million...
- LAG-FREE GAMING: Ultra-fast 240Hz gaming for blur-free visuals and unparalleled...
- HDR & HLG COMPATIBLE: Enjoy brighter whites and deeper black levels for an enhanced viewing...
The Optoma UHD38 is all about raw speed and brightness for gamers who want the lowest possible lag. I was blown away by the 4.2ms response time at 1080p with Enhanced Gaming Mode, plus the 240Hz refresh rate that makes fast-paced shooters feel buttery smooth. The 4000 lumens and massive 1,000,000:1 contrast ratio deliver punchy, vivid images even in lit rooms. The catch is this is a Renewed model with only a 90-day warranty and a 3.6-star rating from just 16 reviews, so you’re taking a gamble on longevity.
✅ Pros
- 4.2ms input lag at 1080p is among the fastest on any projector
- 240Hz refresh rate for ultra-smooth competitive gaming
- 4000 lumens and 1,000,000:1 contrast for bright, detailed images
- HDR10 and HLG support for better color and contrast
❌ Cons
- Renewed model with only 90-day limited warranty
- Only 3.6 stars from 16 reviews — limited user feedback
- No auto keystone or advanced setup features
- Heavier at 9.25 lbs compared to competitors
Which One Should You Buy?
I know picking between these three can feel overwhelming, but the right choice really comes down to whether you prioritize 4K image quality, raw speed at 1080p, or sheer brightness. Let me break down exactly who should buy each one.
BenQ TK700 is right for you if…
- You want a plug-and-play 4K gaming projector with auto keystone so you don’t have to fiddle with manual adjustments
- You play mostly story-driven games on PS5 or Xbox Series X where the 16ms lag at 4K feels responsive enough
- You value built-in Dolby Atmos audio from a 5W speaker for immersive sound without extra gear
ViewSonic PX749-4K is right for you if…
- You’re a competitive gamer who plays at 1080p and wants the 4.2ms input lag for lightning-fast reactions
- You need a bright 4000-lumen projector that works in a living room with some ambient light
- You want the flexibility of a 1.3x optical zoom and USB-C input for connecting a Nintendo Switch directly
Optoma UHD38 Bright is right for you if…
- You’re on a tighter budget and want the absolute fastest 4.2ms input lag at 1080p with 240Hz refresh rate
- You play in a bright room and need the 4000 lumens combined with a massive 1,000,000:1 contrast ratio
- You’re comfortable buying a Renewed model and don’t mind the 90-day warranty for the performance you get
❌ Who Should Skip All of These?
If you’re a hardcore competitive player who only cares about the lowest possible input lag and doesn’t need a projector for movies or casual use, you’d be better served by a high-refresh-rate gaming monitor instead. These projectors are great for console gaming, but none of them will beat a dedicated 144Hz or 240Hz monitor for pure responsiveness in esports titles like Call of Duty or Overwatch.
For most PS5 and Xbox Series X owners, my single clearest recommendation is the BenQ TK700 — it offers the best balance of 4K image quality, easy setup with auto keystone, and solid audio, making it the most complete package for the average console gamer who wants a great experience without compromise.
Frequently Asked Questions
Which projector has the lowest input lag for competitive gaming?
The ViewSonic PX749-4K and Optoma UHD38 both claim a 4.2ms response time at 1080p with a 240Hz refresh rate, which is incredibly fast for a projector. The BenQ TK700 lags behind at 16ms for 4K gaming, but Worth mentioning — 16ms is still perfectly playable for most console games. If you’re a hardcore Call of Duty or Apex Legends player who wants the fastest possible reaction time, I’d go with the ViewSonic or Optoma at 1080p.
Is the BenQ TK700 worth it over the ViewSonic PX749-4K for PS5?
Yes, I think so, especially if you play mostly in 4K. The BenQ TK700 delivers 16ms input lag at native 4K resolution, while the ViewSonic’s 4K lag isn’t specified and its strength is really at 1080p. The TK700 also has auto keystone correction and a Dolby Atmos 5W speaker, which the ViewSonic lacks. If you value convenience and 4K performance over raw speed, the BenQ is the better pick for PS5.
Which projector is brightest — the Optoma UHD38 or the BenQ TK700?
The Optoma UHD38 and ViewSonic PX749-4K both pump out 4000 ANSI lumens, which is noticeably brighter than the BenQ TK700’s 3200 lumens. That extra brightness really helps if you’re gaming in a room with windows or ambient light. For a dedicated dark home theater, the BenQ’s 3200 lumens are plenty, but for a living room setup, I’d lean toward the 4000-lumen models.
Can the BenQ TK700 do 240Hz for Xbox Series X?
No, the BenQ TK700 maxes out at a 16ms response time and does not support 240Hz refresh rates. If you want 240Hz support, you need the ViewSonic PX749-4K or the Optoma UHD38, both of which offer that high refresh rate for smoother motion at 1080p. The Xbox Series X can output 120Hz, but 240Hz is overkill for consoles — it’s more useful if you also connect a gaming PC.
Is the Optoma UHD38 (Renewed) a safe buy?
I’d be cautious here. The Optoma UHD38 is a Renewed model with only a 90-day limited warranty and a 3.6-star rating from just 16 reviews, which is a red flag compared to the BenQ TK700’s 4.0 stars from 138 reviews. The performance specs are fantastic — 4000 lumens, 4.2ms lag, and 1,000,000:1 contrast — but you’re taking a gamble on reliability. If you’re risk-averse, I’d spend a bit more on the BenQ or ViewSonic for peace of mind.
Which projector is best for a dedicated home theater room?
For a dark home theater, I’d pick the BenQ TK700. Its 3200 lumens are enough for a light-controlled room, and the enhanced black details and Dolby Atmos speaker make movies and games look and sound better. The ViewSonic and Optoma are brighter but their contrast and color accuracy aren’t as refined for cinematic use. The BenQ is simply the more polished home theater projector of the three.
My Final Verdict
After comparing all three, the BenQ TK700 is my clear winner for PS5 and Xbox Series X gamers. It delivers the best 4K gaming experience with 16ms input lag, 3200 lumens, auto keystone correction, and a Dolby Atmos 5W speaker — making it the most complete package without any compromises. The ViewSonic PX749-4K is the runner-up for competitive players who prioritize 4.2ms lag at 1080p and 4000 lumens for brighter rooms.
If you’re on the fence, ask yourself this: do you play mostly in 4K or at 1080p? For 4K console gaming, the BenQ TK700 is the no-brainer choice. For raw speed at 1080p, the ViewSonic offers faster input lag and more brightness. The Optoma UHD38 is only worth considering if you’re comfortable with a Renewed model and a tight budget.
