Last Wednesday I received my LG C1 55 inch. It offers a stellar picture and has the gaming features I wanted since this is going to be my primary gaming display. VRR in particular is really useful. I booted up Assassin's Creed Valhalla and VRR almost completely removed all screen tearing on the XSX. The contrast really makes things pop and I don't find this OLED to be dim or not as bright as some have said it is. It did take some calibration to get things where I wanted.
The downside, this screen does not handle reflections well at all. I had just a little bit of light sneak in from behind and the reflection took up a large part of the screen. It was very distracting but luckily I was able to fix the issue but it was surprising to me. So yeah, in a bright room with lots of natural light I would say this TV will not perform well. But in a room where you can limit direct natural light then you'll be pleased.
The FPS counter seems useless. It was just something I wanted to play with. But it doesn't show the FPS of the displayed media but rather the refresh-rate of the TV itself which never changes. So I question the point of the FPS counter when it doesn't show the FPS of the game I'm playing. Maybe I'm not using it right, there are still things I'm figuring out.
