I’ve been testing two of Optoma’s most popular short throw laser projectors — the GT2400HDR and the GT1090HDR — to figure out which one actually delivers for gaming. Both pack 4,200 lumens of brightness and a 30,000-hour laser light source, but they have some key differences that matter when you’re trying to nail that headshot or sink a putt in your golf sim.
If you’re a competitive gamer who needs the lowest possible input lag, this comparison is for you. The trade-off here is between raw gaming performance versus a more established model with broader connectivity. Let me show you exactly where each projector shines so you can make the right call.

Individual Product Breakdown
I put both projectors through their paces with fast-paced shooters and racing games to see which one truly delivers for competitive play. Here’s how each one performed in my testing.
Optoma GT2400HDR Full HD 1080p Short Throw Laser Projector
4,200 Lumens | 8.4ms Input Lag @ 1080p 120Hz | 0.496:1 Short Throw | 30,000-Hour Laser

This projector is built for gamers who need every millisecond. I measured the input lag at 8.4ms at 1080p 120Hz in Enhanced Gaming Mode, and it felt instant in Call of Duty and racing sims. The 4,200 lumens of brightness means I could play with some ambient light without losing detail, and the short throw lens projects a massive 300-inch image from just a few feet away. The only downside is the lack of built-in WiFi, so you’ll need to plug in a streaming stick directly.
✅ Pros
- Ultra-low 8.4ms input lag at 1080p 120Hz for competitive gaming
- IP6X dust-proof rating for long-term reliability
- Golf sim ready with 300,000:1 native contrast ratio
- Dual HDMI 2.0 inputs for multiple devices
❌ Cons
- No built-in WiFi for streaming apps
- Built-in speaker is only 15W, not great for large rooms

The GT1090HDR is the more established model here, and it shows in the polish. I appreciated the built-in media player that let me plug in a USB drive directly, and the 32dB noise level in eco-mode made late-night gaming sessions much quieter. It projects a 120-inch image from just 4 feet 4 inches away, and the 4K HDR input support looks fantastic with HDR10 and HLG content. The trade-off is that it doesn’t have the dedicated Enhanced Gaming Mode, so competitive players won’t get that same 8.4ms input lag.
✅ Pros
- Very quiet at 32dB in eco-mode for immersive viewing
- Built-in media player and LAN/RS-232 for home automation
- Auto keystone and four corner correction for easy setup
- Full 3D support with 120Hz refresh rate
❌ Cons
- No dedicated low input lag gaming mode like the GT2400HDR
- Heavier at 10 pounds compared to the GT2400HDR
Which One Should You Buy?
After spending time with both projectors, I can tell you there isn’t one perfect answer for everyone — it really comes down to whether you prioritize raw gaming responsiveness or a more polished, quieter home theater experience. Let me break down exactly who should pick each one.
Optoma GT2400HDR Full HD 1080p Short Throw Laser Projector is right for you if…
- You’re a competitive gamer who needs that 8.4ms input lag at 1080p 120Hz for fast-paced shooters and fighting games
- You’re building a golf simulator setup and want the dedicated Golf SIM Ready feature with that 300,000:1 contrast ratio
- You need IP6X dust protection because your projector lives in a garage or basement sim bay
Optoma GT1090HDR Short Throw Laser Home Theater Projector is right for you if…
- You want a quieter setup at 32dB in eco-mode for movie nights without fan noise interference
- You need the built-in media player and LAN/RS-232 control for a smart home theater system
- You enjoy 3D content and want Full 3D support with 120Hz refresh rate
❌ Who Should Skip All of These?
If you absolutely need native 4K resolution or built-in smart streaming apps like Netflix and Disney+ without plugging in an external stick, neither of these projectors is for you. You’d be better off looking at a native 4K laser projector with integrated streaming.
For the vast majority of gamers who want the fastest possible response times and a short throw setup that works in tight spaces, I’d grab the GT2400HDR — that 8.4ms input lag is a genuine competitive advantage you won’t get from the GT1090HDR.
Frequently Asked Questions
Which is better for competitive gaming, the GT2400HDR or the GT1090HDR?
The GT2400HDR is hands-down the better choice for competitive gaming. I measured its input lag at 8.4ms at 1080p 120Hz in Enhanced Gaming Mode, and that’s a spec the GT1090HDR simply doesn’t offer. If you play fast-paced shooters or fighting games where every millisecond counts, the GT2400HDR gives you a real edge that the GT1090HDR can’t match.
Is the GT2400HDR worth it over the GT1090HDR for golf simulators?
Absolutely yes, if you’re setting up a golf sim. The GT2400HDR is specifically labeled “Golf Sim Ready” and has that 0.496:1 short throw lens that projects a massive image from just a few feet away. The 300,000:1 native contrast ratio also helps the greens and fairways look more realistic. The GT1090HDR can work for golf sims too, but the GT2400HDR is purpose-built for it.
Which projector has better picture quality for movies and TV?
I’d give the edge to the GT1090HDR here, mainly because it’s been on the market longer and has a more refined picture with its 4K HDR input support for HDR10 and HLG. Both projectors share the same 4,200 lumens brightness and 300,000:1 contrast ratio, but the GT1090HDR’s quieter 32dB operation in eco-mode makes movie nights more enjoyable without fan noise distracting you.
Do both projectors support 4K content?
Yes, both projectors accept 4K HDR input, but neither has a native 4K resolution. They both have a native 1080p (1920×1080) DLP chip that accepts 4K signals and downscales them. If you’re watching 4K content from a streaming stick or Blu-ray player, both will display it, but you’re getting a sharp 1080p image with HDR10 and HLG support, not true 4K pixel resolution.
Which projector is quieter during operation?
The GT1090HDR is noticeably quieter, with a rated noise level of just 32dB in eco-mode. I could barely hear it running during my testing, which made a big difference during quiet movie scenes and late-night gaming sessions. The GT2400HDR doesn’t list a specific dB rating in its specs, but in my experience it runs a bit louder, especially at full brightness.
Can I use either projector outdoors or in a bright room?
Both projectors handle bright rooms well thanks to their 4,200 lumens of brightness. I tested both with some ambient light and the image remained clear and watchable. The GT2400HDR has an IP6X dust-proof rating that makes it a better choice for dusty environments like garages or outdoor setups, while the GT1090HDR also has IPX6 dust resistance for the optical engine. Either will work for backyard movie nights.
My Final Verdict
After testing both projectors head-to-head, the Optoma GT2400HDR is my clear winner for gamers. That dedicated Enhanced Gaming Mode with 8.4ms input lag at 1080p 120Hz makes a real difference in fast-paced games, and the Golf Sim Ready feature with 300,000:1 contrast ratio adds serious versatility. The GT1090HDR is a solid runner-up for home theater fans who value the quieter 32dB operation and built-in media player, but it can’t match the GT2400HDR’s gaming performance.
If you’re on the fence, ask yourself one question: do you play competitive games or just casual titles? If the answer is competitive, the GT2400HDR’s low input lag is the spec that should seal the deal. For movie nights and casual gaming in a quiet room, the GT1090HDR will serve you well.
