@Shewgenja: Nice. I'll probably go Sony on my OLED in that case. My bedroom is relatively dark due to having a smaller window, but my LR is stupid bright.
I would not recommend OLED for a room that gets a lot of sunlight because it will degrade the panel faster. You'd be better served with either a Sammy Q8 or a Sony Z9F to have consistent performance in your living room.
