FAQ

What is color gamut?

Gamut is the range of colors a display can reproduce, usually quoted as a percentage of sRGB or DCI-P3. Wider gamut panels show richer, more saturated colors.

Tips

  • Use the white and gray ramps to isolate luminance banding without color distraction.
  • Wide, posterized bands often come from a 6-bit panel or aggressive video compression rather than your GPU.
