OLED for gaming, you're doing it wrong xD Great for movies and pictures though, although don't look at pictures too long on OLED. Image retention is a pita.
Only way to do anything now!
By far my best purchase I have made for gaming ever, the sheer quality of oled is outstanding and I love having the versatility of 21.9 custom res., 120hz mode, 4k and then true HDR on top of it all on a 55" screen.
Image retention is only a problem if you are someone who exceeds the recommended brightness setting i.e. maxing it more or less out along with watching the likes of sky news for 6 hours a day.
I have my pc set to the recommended luminance setting of 120, although with hdr it goes much higher bit still, I've had mine since November now and played hundreds of hours in games etc., no sign of image retention at all, not even temporary image retention.
