Windows 10: Monitor not active after turning on HDR

I recently picked up another monitor, and after turning on HDR on my laptop it went blank and says it's not active. I don't have a way to turn off HDR anywhere I've looked at tutorials and I don't have the button. How can I activate my external monitor?Thanks in advance

HDR on HDR monitor causes issue on secondary, non-HDR monitor

I have an Aorus AD27QD (HDR) monitor as my primary display and an ultrawide 34UM88-P (Non-HDR) as my secondary. If HDR is enabled in windows and I go to a full screen video on the non-HDR monitor after a few seconds it will flicker blue then become severely
washed out. Coming out of full screen fixes this. If HDR is not enabled full screen shows the colors perfectly normally.

Secondarily, with windows HDR on on the Aorus, the colors dim pretty drastically. HDR content great but anything that isnt HDR is dim enough to make me question if my brightness is turned down. (Its not, its 90/100). The white of a plain browser window
seems so dim its nearly grey. I also tested this on what I know is a particularly vibrant (non-HDR) . HDR on? Terrible and muted. HDR off? Bright and vibrant.

I have played with in-monitor settings, nvidia control panel, factory reset of monitor, basically everything I can think of. Everything points to it being a windows issue.

I also tried out the suggestions from this post. And it pointed me to this
set of OS release notes which didnt solve my issue either.

I could really use some help because I am really feeling like I wasted my money on this monitor.

HDR cant be turned on with dual monitors. help please

I Recently bought a HDR capable monitor (electriQ 28" 4K UHD EIQ-284KMB-HDR). I had some difficulty with hdr, but in the end, downloaded VP9 Video Extension to get HDR to work. Since then, when i have HDR enabled on my monitor, my settings are forced to "show only on 1" where 1 is my new 4k monitor. when looking art display settings, my second monitor is tiny, like 1/4th the size of the 1. If i try to change to "extend these displays", either HDR gets turned off, or the 2nd monitor just doesnt turn on. When HDR is turned off and both monitors are on, i cant turn HDR on as it makes the screens flicker then turn back on with HDR still off and games and apps showing no support for HDR.

I have all my drivers up to date both through a 3rd party app and windows update. This is on windows 11

GPU: Rx 550

CPU: i7 9700k

mobo: z390 Gaming Plus

Ram: 3700 MHZ ddr4

I hope this is enough information to help me. I have searched all ovet the internet and it just the stupid things such as restart pc, update drivers, make sure im clicking the right thing etc.

 

HDR cant be turned on with dual monitors. help please

I have the same problem. I didn't have it with the earlier AMD drivers, but the latest drivers broke the ability to have my main monitor as HDR and my side monitor as SDR. If I enable extended display, the display settings won't let me turn HDR on. So either I have to have both monitors in SDR, or use my main monitor in HDR and get nothing on my secondary. With all of the various updates I don't know if the problem sits with MS or AMD.
