Windows 10: When I connect my two monitors, they both go black.

I just bought a Sceptre monitor and while trying to set it up with my laptop, I made the Sceptre the main screen. Once I made it the main screen, both monitors went black. What do I need to do to fix this?

Hi Ron,

Thank you for posting your query in Microsoft Community.

• What changes did you make in the BIOS? As making the changes in the BIOS is only recommended by Microsoft if done by the manufacturer.
  

• How are you connecting to the 2nd monitor?

I suggest you to follow the steps from this article below:

[Applies to Windows 10 as well]

Regards.

Hi Frank,

Thank you for your interest in Windows 10.

I understand the you have tried to resolve the issue and tried many steps. I really appreciate your efforts in resolving this issue. As you have mentioned that switching the cables make both the monitor
work so I believe its not the driver issue. I would suggest you to try connecting another cable and check if the issue persists.

Below is the Microsoft help article on How to connect a second monitor/ Multi monitors.

Note: The steps for Windows 8/8.1 applies to Windows 10.

If you are facing black screen issue on the second monitor I suggest you to refer to the below thread and follow the steps given:

Thank You.

 

Things to do once connected new G-Sync monitor

I'm getting my G-Sync monitor today.

I think I have to take the following steps:

• Connect 1440p G-sync monitor with DP cable
• Connect second 1080p 60Hz monitor by HDMI
• Startup PC
• Reinstall display driver
• Restart PC (I always do that after display driver install)
• Activate G-Sync in NV control panel (I believe also V-Sync is auto on after that?)
• Set my 1440p monitor from 1080p to 1440p
• Calibrate my 1440p monitor

Also ingame, I should turn off V-Sync?
Are there any problems running a second 60Hz 1080p monitor?

Is there anything else I should do/know?
