Suggestion for Xbox One - PS4 TV

[ImPulSive]

Looking for a dedicated TV just for gaming. Have a plasma for everyday TV and PJ for movies now, but I would rather set up my gaming systems in a spare bedroom for my nephews over the holidays, thus the need for a new TV.

Without going crazy in size or price, any recommendations as to what I should be looking at? 4K, HDR10, low lag I assume. Using Xbox One X + PS4 Pro.

OLED would be nice but the price is still a bit high, $1600 for 55 inch the last time I checked - any BF sales on these or is this price the best I can expect? Then I would have to worry about image retention, so perhaps if the nephews are using it a lot, OLED may not be the best choice.

Recommendations for LCD? I have been searching and reading reviews, and looking at what BF sales have to offer, but thus far I have not found a sure fire winner. Going to have to compromise on something I suspect, but waiting for BF deals first. If I knew what to be looking at this BF, that would help.

Thanks.
