Windows 10: 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 Youtube Video. 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.

Setting up HDR on external monitor

Hi just got an HDR capable monitor, a
U2718q, and am using an HDR capable GPU (GeForce 1070). However, Windows 10 doesn't seem to recognize it as an HDR capable display. I followed the guide

HDR and advanced color settings in Windows 10, and it says that HDR is not supported. Any idea how to fix that? It's an HDR capable monitor, hooked up via DisplayPort to an HDR capable GPU. I'm running Windows 10 Pro Version 1709, OS Build 16299.64 (just
updated it today), and also have the latest graphics card driver.

Any ideas what to do?

 

Windows 10 and Samsung CHG70 32” HDR monitor

I have the lastest version of Windows 10 fully updated as of today and current version of Nvidia drivers. I have SLI Asus Strix 1080 cards.

The monitor is 2560x1440 @ 144hz with HDR. I can enable HDR in display settings. Monitor shows DisplayPort HDR.

So when I try play World of Warcraft and as soon as i click mouse button the display blacks out and goes to saying DisplayPort and not HDR. Colors are at this point messed up. If I alt-tab out and back into game its fine till click mouse again. If I turn
off HDR in display settings it seems fine. If WoW does not support it why does it start with on? Not sure how to fix this.

Next issue. With HDR on again and run Resident Evil 7 which I believe supports HDR the option in game settings for HDR is greyed out.

Anyone have suggestions?
