Test and calibrate your monitor gamma value online. Adjust gamma settings to ensure accurate color display and smooth gray gradients.
Your Gamma: 2.2
A smooth gradient from black to white should appear uniform. If it looks too dark or too bright in the middle, adjust the gamma.
Windows / macOS: 2.2
Linux: 2.2
Gamma calibration ensures your monitor displays colors accurately. Incorrect gamma can make images look too dark or washed out. Most monitors target a gamma of 2.2 for standard sRGB color space.
Gamma is a measure of how a monitor translates input signal into brightness output. A gamma of 2.2 means the monitor applies a power curve where the brightness is roughly proportional to the input value raised to the power of 2.2.
Incorrect gamma can cause images to look too dark or washed out. Proper gamma calibration ensures accurate color representation, which is important for photo editing, design work, and gaming.
The standard gamma value for most monitors and the sRGB color space is 2.2. Some systems like Macs historically used 1.8, but modern displays and macOS versions now use 2.2 as well.
No, this tool is for testing and reference only. It cannot change your monitor hardware settings. Use your monitor OSD menu or operating system display settings to adjust gamma.
