Color uniformity
Check whether red, green, blue, white, and gray screens look even across the panel.
For color and gradient checks
Review color, gradients, and gray balance
Use fullscreen color and grayscale patterns to inspect tint, banding, contrast, saturation, and display consistency.
Why color patterns help
Uniform fills and gradients reveal tint, banding, and contrast problems you may miss in normal content.
Gradient visibility
Look for banding or sudden jumps where a gradient should appear smooth.
Everyday calibration clues
Spot obvious tint or contrast problems before deeper calibration work.
Color check steps
Reset extreme settings first, then review fills and gradients in fullscreen.

Use a normal brightness and display mode before judging colors.
2
Open Screen Tester
Review color screens, grayscale, and gradients in fullscreen.
3
Compare normal content
After patterns, check familiar photos or videos to confirm whether the issue matters in real use.
