Does Vivaldi Support HDR Video?

[sprayer]

Does Vivaldi supports HDR content, on YouTube for example?

It didn't work for me.

@sprayer When reporting problems please always give your system specs, Windows OS, Vivaldi version, etc., and provide a link too where it is relevant.

Does This HDR Video Test on YouTube work for you?

I cannot test as I don't have a 4K monitor.

Here is another 4K Video

no hdr modes in resolution menu, and you can see different color space in statistic window (bt2020 is HDR, bt709 is SDR)

resolution menu should be like this

@sprayer Check the flag. Perhaps it is disabled by default.

vivaldi://flags/#enable-hdr

Bump. Just tested this and enabled the flag, still doesn't work.

did you check the Windows requirements for HDR? https://support.microsoft.com/en-us/help/4040547/windows-10-display-requirements-hdr-video just my 2 cents, I know I can't display HDR
