What to Look For

Backlight Bleed

Light leaking from edges and corners of the screen. Caused by uneven backlight distribution.

IPS Glow

Silvery/purple glow when viewing at an angle. Normal for IPS panels, varies with viewing angle.

Severity Guide

Minimal / None
Screen appears uniformly black. Excellent panel quality.
Minor
Small amount of glow in corners. Normal for most monitors.
Moderate
Noticeable bleed visible in dark scenes. May be distracting.
Severe
Large bright areas along edges. Consider warranty claim or return.

Camera Exaggeration

Photos often exaggerate backlight bleed. Test with your own eyes in a dark room for accurate assessment.

Reduce It

Lower brightness can reduce perceived backlight bleed. Some monitors improve after a break-in period.
