Windows 10: Updated to Windows 10 and now external monitors keep going to sleep in just a few seconds...

Modifying the sleep or screensaver settings has no effect.

External monitor blanking often

Hi,

Please answer these questions to assist you better.

• What is the make and model of your computer and external monitor?
• Have you installed all pending Windows and driver updates?
• Do you get any error message?

I suggest you to install all pending Windows updates in your PC and also update Display drivers. Follow the steps below.

Step 1: I would suggest you to check and install any latest Windows Updates available.

• Go to Start and then Settings.
• Click on Update and Recovery.
• Check for updates under
  Windows Updates.
• Restart the system and check if the issue is resolved.

Step 2: Please refer to the following Wiki article created by
Andre Da Costa on How to: Install and Update drivers in Windows 10.

Windows 10 Anniversary Update - No External Monitor

I have a Surface Pro 4 and a Surface Pro 3, and I use the Surface dock cable to connect both to peripherals including an external monitor. After installing the Windows 10 Anniversary Update, I cannot duplicate or extend to the external monitor. It does
not appear in the display options at all. I have tried deep reboot, restart, updating drivers (although the monitor does not appear in the list in device manager so I can't update its driver), and checked all cables. The external monitor blinks and shows that
there is a display (i.e. it does not go to sleep) but never shows the display image. It is very frustrating.

 

After waking from Sleep Windows does not detect two external monitors

Hi Arifeen,

As per your description, I understand that when your PC goes to Sleep the two external monitors that are attached to your PC do not wake. Upon reboot, the setting personalized in the other two monitors are lost which enforces you to re-set the settings.

The issue is most likely with the graphics driver. Whenever a single monitor is disconnected from a multimonitor setup in Windows, Windows will attempt to move everything from that screen onto the remaining screen(s). Usually, this will not occur when
suspending/hibernating/shutting down the computer. Thus, it is probably because of the graphics driver doing one of the following:

• 'Disconnecting' the monitors when you put the computer to sleep, so when Windows awakens, it must re-determine where to place everything.
• Recognizing the monitors in a different order each time you bring the computer out of sleep, forcing Windows to rearrange your application windows.

To rectify the above, I suggest that you open Windows Update and check if there are any pending updates related to your PC as well as your graphic card driver. If so, disconnect all external devices other than mouse and keyboard, install the updates and
check.

If the above did not help, then I suggest that you uninstall your graphic card driver and re-install the latest driver update available from the manufacturer's website. To learn how to perform the same, refer to the steps outlined in the link below
