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.

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.

It was a chamber over forty feet long, with dark flock paper and dark curtains, with dark painted wainscoating below the paper, and huge dark mahogany furniture.

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:

The luncheon was laid in a low room, with a beam running across the ceiling; the walls, once bright with red flock paper and much gilding, were soiled and dull now, after the manner of a great many of our dining-rooms.

Can your monitor and your browser display an HDR video? If the bottom of each square appears much brighter your browser supports HDR video (an HDR monitor is required).

It was a large room, going far back, and the rich old red flock paper was peeling from the walls in long strips, and blackened with vague patches of rising damp; the ancient clay, the dank reeking earth rising up again, and subduing all the work of men's hands after the conquest of many years.

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.

Can your monitor and your browser display an HDR image? If the bottom of each square appears much brighter your browser supports HDR images in AVIF format (an HDR monitor is required).
