Here you'll find the most compatible example of HDR content (i.e. HDR10) along with an SDR variant and a Dolby Vision profile 5 encode. The only codec supported across all PEDs is HEVC, however, it's unfortunately not broadly supported in browsers
This video has been compiled by us using a selection of short clips from a collection of publicly available demo videos from Sony, Samsung and LG so you can test the HDR on your monitor.
Offering a wider color space, 4K HDR10 demo standards allow images to be viewed with unparalleled brightness and realism thanks to higher brightness and a wider range of color tones.
