I'm surprised at all the LG OLED votes in this thread. Although the LG C9/B9 is a fantastic display with low input lag, I still wouldn't use it for a dedicated gaming TV due to burn-in risk. You, like me, have a dedicated area to use a TV as a gaming device. I prefer to stick to TV's that I know won't burn in. Since most games have static HUD elements, I believe it would only be a matter of how long until it burns in, not if. I read about a user who had the interface of Rocket League permanently burned into their OLED screen, as well as another who had the red hearts from Breath of the Wild permanently burned in. With so many games these days taking upwards of 40+ hours to finish, it's far too easy to have those static elements on display for too long.
I own a Sony X900E for my dedicated gaming room. It's great for that, but obviously doesn't look as good as the OLED in my living room. There's a Hisense H9F series TV that I've had my eye on as a potential replacement to my Sony, and it's crazy that this Hisense is a better gaming TV when you consider how much more I paid for my Sony. Between the lower input lag and increased contrast ratio, the Hisense really stands out as a great option for those looking for a gaming TV while keeping it on the cheaper side.
Don't get me wrong here, I absolutely love my OLED, but I simply couldn't use it for gaming. I'd like to hear from users who have a dedicated gaming only OLED and have had theirs for 12-18+ months. Would be interested to see how many don't have any burn-in. It's different for most users who use them for a mix of viewing content, but as a dedicated gaming display I wouldn't advise to go OLED.
