How to Fix Backlight Bleeding on the Gigabyte M27Q
Causes the uneven light patches (IPS glow and edge bleed) on the Gigabyte M27Q — panel manufacturing tolerance, frame clamping the panel edges, viewing angle amplifying IPS glow, and HDR/backlight modes running at max. Fixes in order: rule out normal IPS glow with a front-on test, reseat the bezel/frame slightly, reduce brightness and change black level, and check whether it worsens in HDR mode before deciding on a warranty swap.
