Backlight Bleed Test
Inspect LCD edge bleed, clouding and angle-dependent IPS glow.
OBSERVE
What to look for
- Fixed bright patches near an edge.
- Cloud-like areas that stay in place.
- Changes that disappear when your viewing angle changes.
MEASUREMENT BOUNDARY
What this test cannot prove
Camera exposure often exaggerates bleed, and IPS glow changes with viewing angle.
