Gamma Calibration Test
Check if your display's gamma is calibrated to the standard 2.2 curve. The checkerboard pattern should blend with the solid gray at the correct gamma level.
How to read this test
- Each row shows a checkerboard pattern next to a solid gray bar for a specific gamma value.
- Find the row where the checkerboard blends with the solid gray - that's your display's gamma.
- Standard gamma is 2.2. If a different row matches, adjust in your monitor's OSD.
- View from normal distance (arm's length) for accurate perception.
Testing guide
How to use the gamma calibration test
Gamma controls the relationship between digital brightness values and visible luminance. Most PC and web content expects a gamma near 2.2, so a wrong gamma setting can make shadows look crushed or midtones look washed out.
Best for
- Checking whether your monitor is close to the standard 2.2 gamma curve.
- Finding washed-out midtones, crushed shadows, or overly dark grayscale response.
- Comparing monitor picture modes before choosing a calibration starting point.
How to run the test
- 1Reset extreme contrast, black equalizer, and dynamic brightness modes before testing.
- 2View the gamma pattern at native resolution with browser zoom set to 100%.
- 3Step back until the fine pattern blends visually with the surrounding reference tone.
- 4Adjust monitor gamma presets until the 2.2 region blends most evenly.
How to read the result
If the lower gamma values blend better, the image may appear too bright or washed out.
If higher gamma values blend better, shadows and midtones may be too dark.
Hardware calibration is still required for color-critical production work.

Frequently asked questions
What gamma should my monitor use?
For most web, Windows, macOS, and gaming use, gamma 2.2 is the practical target. Some video workflows may use different viewing standards.
Why should browser zoom be 100%?
Gamma patterns rely on fine pixel structures. Browser scaling can blur or resample those patterns and make the result misleading.
Does brightness change gamma?
Brightness does not directly equal gamma, but very aggressive brightness, contrast, local dimming, or black equalizer settings can change how the test appears.
