HDR CPU bottleneck

Hi,

I recently bought a HDR10 capable TV. To test it I tried to plug my laptop (i7 9750H and GTX 1650) through HDMI to the TV and played some HDR demos on Youtube. Strange thing that I noticed right away the image was capped at 30Hz by the NVIDEA control panel. I tried to set it to 60 but it just colapsed and switched back to 30. Youtube then set itself to 720p and when I forced it to 4K the image frame rate dropped drastically. In my troubleshooting I opened task manager and noticed that the CPU was on 100% utilization and both integrated graphics and GTX1650 were at 30%. I looked it up and is my understanding that the CPU shouldn't bottleneck HDR video. Any ideas on what I'm doing wrong?

I assume you are using an internet browser to watch the Youtube videos?

 

If so, check to ensure that hardware acceleration is enabled. You should be able to go to settings and type "hardware acceleration" in the search bar to take you straight to it. I use Edge, but should be pretty similar in Chrome:
