ASUS PG27AQDM OLED – vertical banding appeared after ~2 years (not going away)
Posted: 04 Apr 2026, 14:06
Hey, I’ve been using an ASUS ROG Swift OLED PG27AQDM for almost 2 years without any issues, but about 3 days ago I suddenly started noticing vertical banding / uniformity problems.
It’s especially visible on gray backgrounds and looks like faint vertical stripes across the screen (mainly around the center). It wasn’t there before and appeared out of nowhere. (see the pic in attachments)
At first I thought it might be temporary image retention, but it doesn’t go away and seems consistent now. I’ve already run multiple pixel cleaning.
Has anyone experienced something similar after long-term use?
Is this a known issue with this monitor?
