All >25" IPS panels I've tried so far had problems either with highly visible IPS glow in the corners (especially prominent on large panels), dimming at the edges, backlight glow or temporary image retention. Paradoxically, cheap The new 4K 32" 3rd gen QD-OLED panels seem to be the closest to perfection, but I'm not sure if they're suitable for long sessions of programming, web browsing and reading documentation (i.e. displaying static UI elements for hours) due to burn-in and temporary image retention.
At this point, I'd be willing to use a decent 60Hz monitor with thick bezels, only if it didn't have any issues mentioned above.
Which monitors do you use?
