Detailed description：Can get HDR to work fine on the device but It gets turn off when connected to my 4K HDR Monitor using HDMI. Can't fine anything in the manual regarding HDR use externally Not sure if its the HDMI cable or simply that the HDMI port can't do 4K HDR. Don't really want to purchase another HDMI cable nor a USB/Thunderbolt to DP/Hdmi cable/adapter if it won't help.

Anybody know if HDR is possible on an external display and what I'd need to buy?

May I ask what is the model of the monitor you are connecting via HDMI?
Thank you.

Thanks but that wasa NOT my question. How to get HDR to work on an external Display. I'd be pretty stupid if I spent soo much money on 43" 4k 144hz HDR display over a year ago and not figured out how to turn HDR on in windows. Not to mention I said I can get HDR to work but it gets toggled of only when connected to my external monitor. If I had no idea how to use HDR how exactly would I even know it gets toggled off?
The issue is with the zenbook. Either the HDMI port, Cable or Zenbook doesn't support 4K HDR. Since writing this I've tried my PS5 HDMI cable that can do 4K HDR @120fps/hz and the issue is the same. So that leaes the issue being the HDMI port on the Zenbook, the Zenbook itself or it can do 4k HDR externally using a Thunderbolt port which means I'd need a thunderbolt to DP/HDMI cable/adapter. I'd rather not buy something only to return it if it does not work because the Zenbook it's can't do 4K HDR externally hence the question.
