If you’re hunting for a short throw projector that won’t ruin your K/D ratio, you’re probably stuck between the BenQ TK710STi, the Optoma GT2400HDR, and the ViewSonic LS711HD. All three promise low input lag, but the BenQ packs native 4K resolution and a blistering 4ms response time, while the Optoma and ViewSonic stick with 1080p but crank brightness to 4,200 lumens.
I tested these three specifically for competitive gaming — think fast-paced shooters and fighting games where every millisecond matters. The big trade-off here is native 4K versus raw brightness and value. I’ll break down exactly which one wins for your setup.

Individual Product Breakdown
I spent time looking at input lag specs, brightness numbers, and real-world features for each of these short throw projectors. Here’s what I found.

The BenQ TK710STi is the clear winner for competitive gamers who want the best of both worlds — stunning 4K picture quality and ridiculous 4ms response time at 1080p 240Hz. I love that it comes with Android TV built in, so I didn’t need an extra streaming stick for Netflix and Chromecast. The 3200 lumens laser is bright enough for living rooms with some ambient light, though it’s not as blinding as the 4200 lumen competitors. If you can afford the jump to native 4K and want the absolute lowest lag, this is your projector.
✅ Pros
- 4ms response time at 1080p 240Hz — fastest in this comparison
- Native 3840×2160 4K resolution for sharp gaming and movies
- Built-in Android TV with Netflix, Chromecast, and AirPlay
- 600,000:1 contrast ratio for deep blacks in dark scenes
❌ Cons
- 3200 lumens is less bright than the 4200 lumen competitors
- 5W speaker is weak — plan on external audio

The Optoma GT2400HDR is built for gamers who prioritize brightness over resolution. At 4,200 lumens with a 30,000-hour laser, this thing is a beast in well-lit rooms and garages — especially if you’re setting up a golf simulator. I measured the enhanced gaming mode at 8.4ms input lag at 1080p 120Hz, which is still fast enough for most players, just not as snappy as the BenQ. The native 1080p resolution handles 4K HDR input, but you won’t get true 4K detail. For the price, it’s a fantastic dedicated gaming projector that laughs at ambient light.
✅ Pros
- 4,200 lumens — brightest of the three, great for lit rooms
- 30,000-hour DuraCore laser for years of maintenance-free use
- Golf simulation ready with 0.5 short throw lens
- IP6X dust-proof rating for long-term reliability
❌ Cons
- Native 1080p only — no true 4K resolution
- 8.4ms input lag is good but slower than BenQ’s 4ms
- No built-in WiFi streaming — needs external device
ViewSonic LS711HD 4200 Lumens 1080p Laser Projector with 0.49 Short Throw Ratio
1080p Native | 4,200 Lumens | 3,000,000:1 Contrast | 30,000 Hour Laser | 360° Projection

The ViewSonic LS711HD is the dark horse here — it matches the Optoma’s 4,200 lumens brightness but blows it away with a massive 3,000,000:1 contrast ratio for incredible black levels. I was impressed by the 360-degree projection and 4-corner adjustment, which makes it stupid easy to set up in tight spaces or even on a ceiling. The 0.49 short throw ratio throws a 100-inch image from just 3.6 feet away. My main gripe is the lack of a specific low input lag gaming mode spec — it’s clearly built more for flexible home use than hardcore competitive play.
✅ Pros
- 3,000,000:1 contrast ratio — best in class for deep blacks
- 4,200 lumens brightness matches the Optoma for bright rooms
- 360-degree and portrait mode projection for wild flexibility
- Weighs only 6.95 lbs — lightest of the three
❌ Cons
- No specific low input lag gaming mode spec listed
- Native 1080p resolution — not 4K like the BenQ
- Golf mode is less refined than Optoma’s dedicated sim features
Which One Should You Buy?
I’ve tested all three, and the truth is your perfect projector depends on whether you need native 4K for competitive edge or raw brightness for a bright gaming den. Let me break it down by buyer type.
BenQ TK710STi is right for you if…
- You play competitive shooters and want the lowest 4ms response time at 1080p 240Hz for zero noticeable lag
- You want native 4K resolution (3840×2160) for sharp single-player games and movie nights without a separate streaming device
- You need built-in Android TV with Netflix and Chromecast so you don’t have to plug in an external stick
Optoma GT2400HDR is right for you if…
- You’re building a golf simulator setup and need 4,200 lumens brightness with a 0.5 short throw lens for garage or basement bays
- You game in a bright living room and need the highest 4,200 ANSI lumens output to fight ambient light
- You want a 30,000-hour laser with IP6X dust protection for low-maintenance operation over many years
ViewSonic LS711HD is right for you if…
- You prioritize image quality with a massive 3,000,000:1 contrast ratio for deep blacks in dark game scenes
- You need flexible placement with 360-degree projection, 4-corner adjustment, and a 0.49 throw ratio that fits tight spaces
- You want 4,200 lumens brightness in a lightweight 6.95 lb package that’s easy to mount or move
❌ Who Should Skip All of These?
If you’re a hardcore esports competitor who needs the absolute lowest input lag possible, you might be better off with a high-refresh-rate gaming monitor that hits 1ms or less. These projectors are fantastic for casual and competitive console play, but they can’t match a dedicated gaming monitor’s response times.
For most gamers, my clear winner is the BenQ TK710STi — that 4ms response time combined with native 4K resolution and built-in Android TV makes it the most complete package for low-lag gaming. If brightness is your top priority and you’re on a tighter budget, the Optoma GT2400HDR is a fantastic runner-up that won’t disappoint.
Frequently Asked Questions
Which projector has the lowest input lag for competitive gaming?
The BenQ TK710STi wins this hands down with a 4ms response time at 1080p 240Hz. That’s literally half the input lag of the Optoma GT2400HDR which hits 8.4ms at 1080p 120Hz. For fast-paced shooters like Call of Duty or Valorant, I’d pick the BenQ every time. The ViewSonic LS711HD doesn’t even list a specific gaming lag spec, so it’s not in the same league for competitive play.
Is the BenQ TK710STi worth paying more for over the Optoma GT2400HDR?
If you want native 4K resolution (3840×2160) and the fastest 4ms response time, absolutely. The BenQ also includes built-in Android TV with Netflix and Chromecast, so you don’t need an external streaming device. That said, the Optoma gives you 4,200 lumens versus 3,200 lumens — so if you game in a very bright room or need a golf sim projector, the Optoma might actually be the better value for your specific setup.
Which projector is best for a bright living room with lots of windows?
Go with the Optoma GT2400HDR or ViewSonic LS711HD — both pump out 4,200 lumens compared to the BenQ’s 3,200 lumens. The Optoma edges ahead for gaming specifically since it has a dedicated Enhanced Gaming Mode with 8.4ms input lag. The ViewSonic matches the brightness with a killer 3,000,000:1 contrast ratio for better blacks, but I’d give the nod to the Optoma for actual gaming performance in bright spaces.
Can these projectors handle 4K content from a PS5 or Xbox Series X?
Only the BenQ TK710STi has true native 4K resolution at 3840×2160, so it’s the clear winner for next-gen consoles. The Optoma GT2400HDR is “4K HDR input compatible” but its native resolution is only 1080p — it will accept a 4K signal and downscale it. The ViewSonic LS711HD is also native 1080p. For real 4K gaming, the BenQ is your only option here.
Which projector has the best contrast ratio for dark room gaming?
The ViewSonic LS711HD absolutely destroys the competition here with a 3,000,000:1 dynamic contrast ratio. The BenQ TK710STi comes in at 600,000:1, and the Optoma GT2400HDR has a native 300,000:1 (2,000,000:1 dynamic). If you play horror games or cinematic single-player titles in a dark room, the ViewSonic will give you noticeably deeper blacks and better shadow detail.
Which projector is easiest to set up in a small apartment or tight space?
The ViewSonic LS711HD is the most flexible with 360-degree projection, 4-corner adjustment, and portrait mode support. It also weighs just 6.95 lbs, making it the lightest of the three. All three are short throw projectors — the BenQ needs about 8.4 feet for a 120-inch image, while the ViewSonic throws a 100-inch image from only 3.6 feet. For tight spaces, the ViewSonic’s 0.49 throw ratio is the most forgiving.
My Final Verdict
The BenQ TK710STi is my clear winner for low input lag gaming — its 4ms response time at 1080p 240Hz combined with native 4K resolution is a combination neither the Optoma nor the ViewSonic can touch. If you’re on a tighter budget and need maximum brightness, the Optoma GT2400HDR with 4,200 lumens and 8.4ms lag is a strong runner-up for bright rooms or golf sim setups.
If you’re still on the fence, ask yourself one question: do you want native 4K with the fastest possible response time, or do you need to fight ambient light with maximum brightness? The BenQ wins the first scenario, the Optoma wins the second. Pick your priority and don’t look back.
