Monitor Color Test
Inspect gradients, color transitions, and fullscreen uniformity to spot banding, tint shifts, and obvious panel inconsistencies.
Display context
Color inspection is easier in fullscreen mode with browser chrome removed.

Start fullscreen color test
Use large gradients and color transitions to inspect banding, uniformity, and tonal consistency.
Look for visible steps between shades, uneven brightness, dirty-screen effect, strange tint zones, and crushed or abrupt transitions.
What this test is good at
It is a visual inspection tool, not a substitute for hardware calibration.
- Banding — gradients break into visible steps instead of staying smooth.
- Uniformity problems — one part of the panel looks darker, warmer, cooler, or patchier.
- Compression or signal issues — transitions look rougher than expected.
- General panel quality checks before keeping or returning a new display.
Pair it with other monitor checks
One test rarely tells the whole story for display quality.
Run the Dead Pixel Test for point defects and the Refresh Rate Test if motion smoothness or configured Hz is the real concern. Combining the three gives a much clearer first-pass panel audit than normal desktop use alone.
Frequently Asked Questions
How do I test monitor colors online? +
Use solid color screens and gradients, view the display straight on, and look for obvious tint, banding, crushed shadows, blown highlights, or uneven brightness.
Can this replace a hardware colorimeter? +
No. A browser color test can reveal obvious problems, but precise color accuracy needs a hardware colorimeter and calibration software.
Why do gradients look banded? +
Banding can come from low panel bit depth, bad color settings, compression, browser or GPU output settings, or an overly aggressive monitor mode. Reset display color modes before judging the panel.
