Optoma UHD38x: True 4K Brightness with Ultra-Low Gaming Lag
The Optoma UHD38x is a 4K UHD (3840 × 2160) DLP projector built for people who want one machine for movie nights, live sports and fast competitive gaming. At 4,000 ANSI lumens it stays bright in rooms with some ambient light, and its Enhanced Gaming Mode cuts input lag to just 4.2 ms at 1080p 240Hz, which is among the lowest of any 4K home projector.
Key Features
- True 4K UHD resolution: 8.3 million pixels on screen for sharp text, detailed movies and crisp game HUDs.
- 4,000 lumens: bright enough for living rooms, game rooms and meeting spaces, not only dark home theaters.
- 4.2 ms input lag at 1080p 240Hz: console and PC gamers get near-instant response in shooters and racing games.
- HDR10 and HLG: wider contrast for streaming, Blu-ray and broadcast HDR content.
- Full HD 3D support for 3D Blu-ray titles (3D glasses sold separately).
- Long lamp life: up to 4,000 hours in Bright mode and 15,000 hours in Eco mode.
- Built-in 10W speaker plus 3.5 mm and optical audio outputs for a soundbar or AV receiver.
- Two HDMI 2.0 ports with CEC, plus USB-A power, RS232 and a 12V trigger for integrators.
Who Is the UHD38x For?
- Gamers: PS5, Xbox Series X and gaming PCs that run 1080p at high refresh rates.
- Home theater upgraders moving from a 1080p projector to 4K on a 100–150 inch screen.
- Bright living rooms where a TV-size picture is not enough but full light control is not possible.

Frequently Asked Questions
Is the Optoma UHD38x good for gaming?
Yes. In Enhanced Gaming Mode it reaches 4.2 ms input lag at 1080p 240Hz, which is faster than most TVs and most 4K projectors.
How far should the UHD38x be from a 100-inch screen?
Between 10 ft 11 in and 12 ft 1 in (3.32–3.68 m) from lens to screen, depending on the zoom setting.
Does the UHD38x have lens shift?
No. Place it level with the bottom or top of the screen and use the digital keystone only for small corrections, since keystone slightly softens the image.
