Bests & Worsts Reviews from Amazon

I purchased a Sony X900H 55", an LG OLED CX 55", and the TCL 55R635. I played multiple games and watched 4k HDR content on all of them. Dollar for dollar this unit cannot be beat. The only issue is viewing angles, which I explain at the end. The LG OLED CX 55" has the best picture quality hands down, but it is also $1000 more expensive, the HDR brightness isn't nearly as bright, and if you play PC games for hours upon hours like I do, the threat of burn-in is legitimate. It also cannot do 4k at 120 fps and HDR at the same time. I would rather have 2560x1440 with HDR than 4k at 120 without it. If you are a casual gamer and watch varied content, then OLED would be the way to go, that is if you want to burn an additional $1000. The Sony X900F has HDMI 2.1, however it does not yet support 4k at 120hz. Apparently this will be enabled down the road via a firmware patch. For me this is dead on arrival. I am not buying future capabilities in a TV I own now. The TCL has excellent picture quality and the THX Certified Gaming Mode works very well with my PC. My rig can play games like Doom and Destiny 2 at 4k at 120 fps and it is butter smooth. Even games like Grim Dawn benefit. Running anything at 120 fps is amazing. This is the future of gaming. 4k HDR content like Planet Earth II look gorgeous at this price point. I am shocked that this picture quality can be achieved at this price. Again, you aren't going to achieve those inky blacks that OLED gives you, but the difference isn't that great between the two. The only major downside to this TV is the viewing angles. As soon as you begin to move off-axis, to the left or right of the screen, the color begins to drop off almost immediately. It isn't necessarily a deal-breaker, but you should be mindful if you are going to have this in a living room with seating far to the left or right of the screen.
