I might downgrade to 1080P for the higher frame rate and the superior image quality of OLED even if it's 21.6". I just want the price to be good and for it to have great HDR support and Freesync/Gsync compatible. It must also be high refresh rate (at least 144Hz).
The more I use my IPS LG 24UD58 at 3840x2160@60Hz, the more I love it and think there is never anything better than it
