HDR display not detected/abysmal 4K performance

I just installed the latest display driver update, and thought I could just start playing HDR content from YouTube and Netflix happily - I WAS WRONG.


Here are my problems.

1. The Windows 'Video playback' settings doesn't detect an HDR display connected. My PC is an i5-7400 connected via HDMI 2.0 to my LG OLED65B6T. EVERYTHING IN THIS CHAIN IS HDR/4K60/HDMI 2.0 compatible. WHY ISN'T WINDOWS DETECTING A COMPATIBLE DISPLAY?

2. When 'forcing' HDR through Windows Display settings, My TV correctly recognizes the HDR signal, HOWEVER this does not auto detect whenever HDR video is being played, so this is NOT a solution, however it PROVES that my display and the rest of my PC components are HDR compatible.

3. When playing back ANY 4K video (HDR or otherwise), playback slows to a crawl. Audio plays fine, but video appears choppy and in slow motion. Task Manager reports that the GPU is at 100% load, CPU at ~50% load with 100% spikes, and RAM usage is 5.5Gb/8Gb. No other applications are open/running in the background during this time. This is regardless of which 4K content I play and what I use to play it on - YouTube/Netflix/Windows Media Player/VLC, etc. WHY IS 4K VIDEO PLAYBACK IMPOSSIBLE ON MY MACHINE THAT IS LESS THAN A YEAR OLD???


I waited SO PATIENTLY for a driver update because we were told TIME AND AGAIN by Intel that the HDR support was coming. Now that it's here, not only does it NOT detect a compatible HDR display, but ANY 4K video is unwatchable.

Needles to say, I am incredibly ****** off.
