Windows 10: 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

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.

PC:

i5 7600k

GTX 1080ti

16GB 3000Hz Corsair RAM

Windows, CPU and GPU on latest drivers available.

Monitors:

I could turn on the HDR and WCG setting on initially today when I connected a new HDR TV.

Hello,

Thank you for writing to Microsoft Community Forums.

I understand that you are unable to turn on HDR and WCG color settings in Windows 10. This issue might occur due to incompatible drivers.

I suggest you to roll back the display drivers and check if that helps. Refer the steps mentioned below:

1. Press 'Windows
+ R' key together on your Keyboard.

2. Type 'devmgmt.msc' and hit enter.

3. Expand the display adapter option from the list.

4. Right click on the driver and click on 'Properties'.

5. Click on 'Driver' tab and check for 'Roll Back Driver'. If the roll back option is available, roll back the driver and restart the
computer.

If you are still facing issues with color after enabling HDR on your PC and if you’re using an HDMI connection and your display supports HDR over a DisplayPort connection, use DisplayPort instead to connect your PC and display.

• If HDMI is your only option, use that, and then do one of the following:
  

Reduce the frame rate

• 1. Select Settings > System > Display > Advanced display settings, and then select Display adapter properties.
  2. In the display’s Properties box, select the Monitor tab, select 30 Hertz for the Screen refresh rate, and then select OK.

- OR -

Reduce the resolution

• 1. Select Settings > System > Display > Advanced display settings, and then select Display adapter properties
  2. On the Adapter tab, select List All Modes.

In List All Modes, select the setting that includes 1920 by 1080, 60 Hertz, and then select OK.

Hope it helps.
