Windows 10: Windows 10 1 out of 3 Monitors is Not Working

Hi Community,I have some issue regarding the 3 Monitors setup.

Windows 10 with 3 Monitors

No, Windows 10 is not allowing me to extend my desktop to a 3rd display.

I understand how to set up 3 monitors, and it was working fine in Windows 7. Windows 10 shows all 3 monitors, but only allows me to use 2 at a time. From my reading through these forums and other searches, it looks like many people are having this same issue.

I am using 2 DVI monitors and 1 HDMI; not a DisplayPort. It looks like people can get 3 or monitors working with a DisplayPort, but I haven't seen any solutions to getting 3 standard monitors functioning in Windows 10. Are there any other suggestions or
fixes from Microsoft for this?

 

Windows 10 Update - Now my dual monitors do not work

Hi,





One of the possible reasons why Windows 10 was unable to detect your dual monitor is an outdated or incompatible graphics driver. To best address your concern, we need you to answer the following questions:

• Which Windows 10 build are you using?
• Have you already tried performing the troubleshooting steps suggested by
  Mauro Cavallin on June 16, 2017?
• Are both of the monitors not working just like what the original poster was experiencing? If yes, have you tried disconnecting one of the monitors? What was the outcome?
• What troubleshooting steps have you done so far?

We will be waiting for your response.

 

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There could be a possibility that this issue might have occurred due to outdated display drivers or corrupted drivers on the system.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