Windows 10: Windows 10 with 3 Monitors

Windows 10

AMD Radeon 7700 series, Driver Radeon Software Version 20.3.1


First, I'll state that all 3 monitors used to work perfectly up until a restart a few weeks ago.


I have three monitors plugged directly into the card. All three used to work perfectly up until I restarted the PC a few weeks ago. All three are connected with HDMI to mini-DP. If I have three of them connected, only two monitors display. If I disconnect one of the active monitors, then the third monitor works. I cannot get more than two at any one time. This tells me it's not the monitor hardware. It's not the cables either.


Windows seems to recognize the third monitor.

• all three monitors are shown in Device Manager.
• in the Windows Display setting, it shows a third monitor but trying to activate it and this pops up: "The display settings could not be saved. Please try a different combination of display settings". And then refuses to accept it.

All of this is pointing towards some sort of recent windows update. Since I don't restart my PC much, the only updates are likely to be

Windows updates in 2020

KB4551762

KB4534132

KB4541338

KB4538674

KB4537759

KB4528759

KB4524569

KB4525419



So far I have

• updated & rolled-back graphics drivers
• dismantled the PC, cleaned it up, and put it back together
• switched out every cable
• started unrolling each and every Windows update in 2020
• hit it
• spent hours and hours and days and days internet crawling for an answer. The closest I've found has beenthis in the Microsoft Community.

What in the name of good grief is going on.

Does Windows 10 Support 3 monitors?

Hi Chuck,



As per the description, you are experiencing issue with you want to know Does Windows 10 support 3 monitors because you are able to see the display on 2 monitors but the third one is grayed out.



I certainly understand your concern.

There could be a possibility that this issue might have occurred due to outdated display drivers or corrupted drivers on the system.

I would suggest you to try the following methods and check if that helps.



Method 1:

Run inbuilt Hardware & Device troubleshooter

  Type Troubleshooting and click

  Now click on view all option.

• 
  When the Windows Update control panel opens, click on “Check for Updates” on the top left corner to receive a fresh list of updates.
  

Step 3: If the issue persists, I would suggest you to uninstall and reinstall the Display driver. Please follow the steps mentioned below to uninstall the display driver.

  Expand Display adapters.

  Right-click the display card driver and click
