Please do more research. Hdtvtest videos are a good start.
The x900h uses the same x1 chipset as the 900e, though its options menu is more limited than the 900e so ultimately, it’s a worse implementation sans the input lag and single 2.1 port which will be useless outside of the handful of aforementioned games.
I’m not in the oled camp like it’s a faction, but the black level, motion response and uniformity are night and day better than lcd. Maybe Sony mini led quantum dot color conversion will be better whenever that hits.
I mean it can’t have as good of black level, but perhaps overall that’ll be close enough plus way more bright. and also still not as good of motion response as oled
And yes, burn in on 2018 panels or newer is a proven non issue when watching varied content.
For the people that actually do play the same games with the same hud 8 hours+ for months, the q90t is the best 2020 lcd.
