I will do reinstall soon to version 1903. I have RX 580 so GPU definitely support it (I think) but I am still on Wind(previous update make a big mess of my system so I reinstalled and disabled update).

The display must also have HDR turned on. In Windows 10's Settings->Display I have HDR10 and Advanced Color turned on and Resolution is set to 3840x2160. I have the Stream HDR Video setting turned on in Windows 10's Settings->Video Playback.

(DP 1.2 also works for Kaby Lake HD Graphics 630 or Coffee Lake UHD Graphics 630 with the latest Windows 10 graphics drivers installed.) I'm using Windows 10 1709. If the display is HDR-10 capable and you want to use it directly instead using of VLC's tone-mapping, then you need to be running Windor higher, the GPU must support HDR-10 and you must use your video graphic adapter's DisplayPort 1.4 or HDMI 2.0 connection. Like your monitor it doesn't support real HDR or real wide color gamut.) (My monitor is HDR capable if I use its HDMI 2.0 connection in HDR mode but not if I use its HDMI 1.4 connection. VLC uses tone mapping to simulate HDR if the display or the video graphic adapter's HDMI connection is not HDR capable. To check that VLC is set to use hardware decoding so it can play 4K HEVC smoothly, go to Tools->Preferences->Input/Codecs and make sure that Hardware accelerated decoding is set to 'Automatic'. Note that the GPU must support HEVC hardware decoding or video playback will be too choppy to watch. I use VLC 3.0.7.1 Ventari to play UHD HDR-10 video.
