I think hes referring to the text fringing on the LG WOLED panels.
In the 27 inch category there basically isn't any good alternative option. The LG or ASUS 27 OLED are pretty much best in class for HDR. I have the LG and i'm in love with it. Dead Island 2, RE4 Remake etc look incredible in HDR.
Text fringing is a thing but doesn't bother me at all. I installed Mactype which improved things a bit and theres already a big public push for MS to actually fix font rendering in Win11, as i'm sure they will one day.
If you want good HDR you gotta settle on these two, or a 30inch+ OLED panel. I'd suggest getting one of these and simply trying it out before writing it off entirely for the font rendering issue.
