Windows 10: Windows 10 Pro fails to send signal to second monitor after sleep

Hi folks! I've been having issues for years since I upgraded from win7 pro to win10 pro with random BSOD, and more recently in the last six months or so with always fail to install windows upgrades. With the recent major zero day exploit released I saw on the news I buckled down and tried to get it working. SFC scans and DISM failed and couldn't fix the issue, but luckily enough I saw someone suggest a repair install, an in place upgrade.

Awesome solution, since that was the biggest thing keeping me from doing a reinstall was the hassle of my thing going again. Laziness I know. Anyways I did the in place upgrade repair install and everything seems to be great. Windows updates work (more or less), and I haven't had a random BSOD yet (fingers crossed). Been going about a week now.

My one major issue is the secondary monitor receives no signal after resuming from sleep. I have no idea what could be causing this. After a restart or shutdown it works fine till I put the computer sleep. Even if the computer puts the displays to sleep after x minutes of inactivity, they both come back when I start some activity/press a key.

I'm unsure how to troubleshoot this at the moment since I did what I could think of. NVIDIA Driver re-install, checked device manager and etc. Be happy to do everything again or anything suggested.

Some pertinent info perhaps.
Monitor is running on a VGA cable
I'm on version 1909 (OS Build 18363.535) of Windows 10 Pro

Edit: Ah, I should add that if after it resumes from sleep I use the windows key + P I can choose to extend the desktop again to the 2nd monitor, but the monitor fails to show up in display settings.

Error: No signal on second monitor after upgrade to Windows 10

Hi,

Thank you for posting in Microsoft Community, we appreciate your interest in Windows 10.

I understand your inconvenience caused to you with accessing the second monitor, we will help you with this issue.

This issue might have occurred due to outdated/ corrupted drivers.

As you have already tried to update the drivers and issue still persists, I suggest you to uninstall the existing drivers for second monitor and re0install them from the manufacturer's website.

Step 1: Steps to uninstall the drivers for the Display Adapter.

• Press Windows key + X key when you are at desktop.
• Select Device Manager.
• Expand Display Adapter.
• Right on the Display Adapter and click on
  Uninstall.
• Restart the computer.

Step 2: Also, contact the manufacturer's website and try to install those drivers for your device.

You can install Windows 8/8.1 drivers in compatibility mode if there are no Windows 10 compatible drivers.

Follow the steps to install in Compatibility mode:

• Download the updated driver from the manufacturer’s website.
• Right click the driver installation file and select
  Properties then tap or click the Compatibility tab.
• Place a check in the Run this program in compatibility mode for: box.
  
• Tap the drop down box and select a previous operating system, then tap or click
  OK.
• Try installing the driver and check.

Second Monitor has No Signal

I recently updated my computer to windows 10 and bought new monitors but I can't get my second monitor to receive any signal. One monitor is connected directly to my vga port but the other monitor is plugged into a DVI-I port with a vga to DVI-I adapter.
My desktop recognizes that there is a second monitor and I've checked both the cords and the adapter for the monitor several times. I've looked at several forums and tried every setting I can think of but even though the monitor is set to extended it still
doesn't get any signal even though windows can be dragged into that monitor.
