Edge-to-edge display inspection
Check every zone of your screen.
Compare the center, edges, and corners with even fields and reference patterns for brightness variation, color consistency, and pixel issues.
Compare areas visually—no sensor or upload required.
01 / Test deck
Center, edge, corner—compare them all
Start with uniform gray, then use black, white, and color to see whether an apparent zone difference persists.
Animated and changing-brightness tools are optional. Stop if a pattern causes discomfort.
02 / Method
Use a consistent scan path
Spatial comparisons improve when position and timing stay steady.
- 01
Anchor
Sit centered at your normal viewing distance and choose a reference area.
- 02
Sweep
Compare center, edges, and all four corners without changing settings.
- 03
Shift
Change your viewing angle and repeat to identify angle-dependent behavior.
Read before judging
Uniform does not always mean identical from every angle
Panel technology, size, viewing distance, and angle can create perceived differences. Zonal helps structure a comparison but does not quantify uniformity.
03 / Useful answers
Before you inspect
Which pattern is best for uniformity?
Mid-gray is a useful starting point, followed by white, black, and solid colors to compare how the same zone behaves.
Why does a corner change when I move?
Many panels shift in brightness or color with viewing angle. Note whether the appearance follows your head position.
Does Zonal calculate a uniformity percentage?
No. The site provides visual reference fields and does not access a colorimeter or produce measurements.
