Windows 10: Why is screen going black when I extend display?

Hello, I am having a problem that just started today after booting up my computer. I have 3 monitor display, but for some reason the middle display is black despite bringing on and the computer detecting. I have done enough to know it is not the montior because when I change display settings to duplicate displays the montior is fine. It is only when I change the display options to extend these displays. I have tried changing the ports in the GPU around, checked to make sure my drivers are updated, and ruled out the idea that the monitor has gone bad. Please if anyone has any ideas or options

:)

 

Issue with black screen, dual display, ATI Integrated GPU

Hi,

I suggest you to follow the below methods and check if it helps.

Method 1: I suggest you to go to device manager and disable the display drivers, check whether the issue persists or not.

• Press Windows + X keys and click
  Device manager.
• Click to expand Display adapters, right click the second adapter and click
  Disable.
• Restart the computer and check whether the issue persists or not.
• Repeat the same steps to disable the first display adapter and check if it helps.

If you find the issue is with anyone of the display adapters then, I suggest you to update the display drivers from the manufactures website for Windows 10 and check if it helps.

Method 2: I suggest you to follow the steps form the below article for
“Black Screen” issues and check if it helps.

Second (extended) Display recognized but black

I just attempted to fix black extended display issue by upgrading Nvidia 765m driver. Nothing changed. I tested dual display function with Nirsoft's MultiMonitor tool (which DOES show the blue windows background image on the extended monitor in preview),
but the extended display remains black. I think the issue may have been caused by a recent Windows-10 update. I have also tried swapping monitors, but both are good elsewhere. I could use some additional suggestions.

 

no audio on extended display

We would like to know more information from your end to know what is the next possible step that we can offer for you to resolve your issue.

• Were you able to get an audio on your extended display before? Or is this the first time that you will set up an extended display with your computer?
• Aside from the HDMI cable, have you tried using VGA cable instead to connect to your extended display?
• Can you verify if you have any audio on your speakers if you are not connected to the extended display?

We look forward to your reply.
