The Optoma UHD35 is listed as featuring a 240Hz refresh rate when its Enhanced Gaming mode is activated. This is an amazing performance specification, but there are some caveats.
Nothing has really changed in the couple of months since my UHD50X review. There are no gaming consoles that support 240Hz. The PS5, Xbox Series S, Xbox Series X, and PS5 next-generation consoles, graphical powerhouses that they are, (especially compared to previous generation consoles) will have to drop the resolution to 1080P to even realize 120Hz game performance. These consoles will have to adopt dynamic resolutions, so the display can refresh the screen in sync with every frame.
The ability to game at 240hz is currently limited to gaming on a PC and then only at 1080P resolution. Even with these current limitations, each increase in refresh rate is generally followed by a reduction of input lag. But I’m getting ahead of myself. Optoma claims 16.7ms at 4K 60Hz, 18.9ms at 1080p 120Hz, and 4.2ms at 1080p 240Hz. As with previous models, the 1080p limitation at 120Hz and 240Hz is a limitation of current gaming consoles, as well as a limitation of the software, but there’s always the possibility of addressing these gaming systems’ limitations through future updates. The main reason for the 1080p limitation is the HDMI 2.0 specification. Even with a computer powerful enough to run a game at full 4K resolution and a high refresh rate, the projector would still be limited. Sadly, the HDMI ports on the Optoma UHD35 are still limited to HDMI 2.0 and 1.4, so realistically, high-resolution, high-refresh gaming is never going to be possible on this projector.
