How to Fix Color Banding on a Monitor
Smooth gradients show sudden visible stripes or uneven transitions.
Before you begin
Start with reversible settings checks. Keep your device supported and powered safely. Do not force connectors, open sealed batteries or try high-voltage repair steps.
How to troubleshoot the problem
- 01
Check a different gradient sample
Compare several images to rule out a compressed source graphic.
- 02
Review display color-depth settings
If available, confirm the output is using an appropriate color depth and signal mode.
- 03
Disable extreme enhancement modes
Aggressive contrast or vivid modes can exaggerate banding.
- 04
Compare another browser or display
Browser color pipelines and display panels can differ.
- 05
Review official graphics driver settings
Use the GPU maker’s documented options rather than unknown tweak tools.
Check the result.
Run the smooth gradient test again and evaluate whether the transitions appear less stepped.

If the same problem occurs in multiple compatible applications or devices after safe checks, follow the manufacturer's exact support instructions or ask a qualified repair professional. A browser test cannot prove every hardware component is healthy.
