About Greyscale Test
Check every gray step from black to white for crushed shadows, clipped highlights and color tint.
A greyscale test, also searched as grayscale test, shows a row of gray steps from pure black to pure white. A good display shows each step as a separate, neutral gray. A poorly set screen merges the darkest steps into black, merges the brightest steps into white, or adds a blue, green or pink tint to the middle tones.
What To Look For
- Black crush: the first few dark steps look the same, so shadow detail is lost.
- White clipping: the brightest steps blend together, so cloud and snow detail is lost.
- Tint: grays look colored instead of neutral.
- Banding: uneven jumps between neighboring steps.
How To Fix Greyscale Problems
On a TV or monitor, adjust brightness until the darkest steps just separate, then adjust contrast until the brightest steps stay distinct. Use the warm or 6500K color temperature to remove a blue cast. On phones, switch to a natural color mode. For detailed tuning, continue with our Gamma Test and Black Level Test.

Questions People Ask About Greyscale Test
01 What is a grayscale test?
It shows evenly spaced gray steps from black to white so you can check shadow detail, highlight detail and neutral color.
02 Why are my dark gray steps black?
Brightness is set too low or the black level setting is wrong, which crushes shadow detail.
