Take the test

Welcome to the wide-gamut test page

This is a test area to check if your monitor or screen supports a wide range of colors and other color-related tests. The test is organized into three sections:

COLOR TEST is for color gamut, HDR and new image formats compatibility.

IMAGE SDR is a showcase of images to guide you through the difference between sRGB and Wide-Gamut color space in a Standard Dynamic Range.

IMAGE HDR is a showcase of images to guide you through the difference between a Standard Dynamic Range and High Dynamic Range images.

Choose the test using the tabs below. Let's get started!

Does your monitor support ICC colour profiles? Green YES - Red NO

Can your monitor display a wide colour gamut? If you see a uniform red square, your monitor cannot display a wide gamut of colours.
If you see the W letter inside the square, your monitor is wide gamut.

How far from sRGB is your display color gamut? The more difference you see inside the squares, the further your display color gamut is from sRGB standard.
