Windows 10: Second Display wont work

Since updating Windows 11 to version 23H2 my second display wont activate, its recognized and detected but wont activate. I have tried resetting my cache in the amd software then restarting the computer, disconnected and reconnected the display, tried amd eyeinfinitywhich is essentially stretching the display to the other monitor, but nothing worked. I have a AMD Ryzen 7 5800x, Gigabyte X570s, and a AMD radeon RX 7900XT graphics card.

Windows won't detect by second display.

I have my monitor and TV connected to my GPU. In Display Settings, under Rearrange your displays I have the 2nd highlighted. Clicking the Detect button will render: Code:

Second Display Working But Not Available

Weird problem, it's probably a driver issue but I'm relatively new to Win 10 (meh) so I'm asking before doing. I have 2 displays, my main display, identified as display 2 is a displayport connection, while my secondary display identified as display 1 is on a HDMI to VGA adapter. All of this was configured and working the other day. It appears, but I'm not 100 percent sure, that when I updated my Nvidia graphics driver that my secondary display stopped working. I enable/disable the second display regularly so I can't be 100 percent sure when the issue started. I also just uninstalled and then reinstalled Nvidia GeForce Experience not wanting to start after the Win10 update from Win7, though it's likely this didn't have anything to do with the problem.

Anyways, when I start my computer, the Post, UEFI/BIOS and pre login Windows starting screen all appear on my secondary display so I know it's not a hardware issue. When the Windows login screen appears display is switched to my main display and the secondary goes to sleep. When I go into my Nvidia control panel to enable the secondary display, under set up multiple monitors, I see both my displays listed. My main display is listed with a checked checkbox next to it. My secondary display is listed with an unchecked checkbox next to it. Though not greyed out, the checkbox for the secondary display cannot be checked. When I do a display detect in Nvidia control panel it still shows both displays listed.

Now, if I go to my Win10 device manager, under monitors, only my main display is listed. If I do a detect displays in Win10 device manager it says no new displayed detected. This was all working fine the other day, don't know if it's a Windows update that broke it, the latest Nvidia driver or some setting I changed. I had been playing with the refresh rate on the main monitor as well as the display specific setting/enable settings for the selected display model under Set up G-SYNC. I've tried switching these setting back and forth but it has no effect on the detection of the secondary display. Thanks in advance.
