Focused checks for hard-to-see issues
Bring hidden screen flaws into view.
Strip away the desktop and inspect dark fields, flat tones, and gradients that can make subtle glow, bleed, clouding, or pixel issues easier to notice.
Dim the room for dark checks; return to normal light for color work.
01 / Test deck
Look where screen problems like to hide
Darkness first, then neutral fields and color references to help separate a repeatable issue from room reflections.
Animated and changing-brightness tools are optional. Stop if a pattern causes discomfort.
02 / Method
Observe in layers
Dark-field checks need different conditions from bright and colored patterns.
- 01
Adapt
Dim the room for the black field and wait briefly for your vision to settle.
- 02
Move
Change your viewing angle to distinguish panel behavior from a reflection.
- 03
Verify
Return to normal light and compare the same area on gray and solid colors.
Read before judging
Glow, bleed, and reflections can look alike
Panel technology, brightness, camera exposure, viewing angle, and room light can all change the appearance of dark areas. Inspect with your eyes, not a phone photo alone.
03 / Useful answers
Before you inspect
Is every bright corner backlight bleed?
No. Viewing-angle glow and reflections may change as you move, while a persistent irregular area may behave differently. This tool cannot classify it for you.
What brightness should I use?
Start at the brightness you normally use. Extreme brightness can exaggerate dark-field differences.
Why do the controls disappear?
They fade to reduce stray light during dark checks. Move the pointer, tap the screen, or press a key to reveal them.
