I didn’t find info from Rtings, my go-to TV site, but here’s one from PCMag:
51.2 milliseconds measured input lag on Game mode is a bit concerning; if your game is 60fps, that’s 3 full frames and then some of input latency. I suspect you may be able to get a lower input lag by turning off upscaling features, but I’m not certain that is possible.
A basic summary from this review: This TV will be outperformed by 1080o televisions of similar price when displaying 1080p content, but it can display 4K content, so if you’re looking for an affordable and unexceptional entry into 4K, this is a pretty good deal. The price offered here is very competitive.
