Windows 10: External monitor and sleep

I have a laptop with an external (HDMI) monitor. When it sleeps the windows that are open change to a smaller size, sometimes but not always, is this typical or is something amiss? Project is always set to 'Second screen only'.

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

External Monitor with Quicken

Hi Mark,

It is possible that the display resolution automatically adjusts after connecting to an external monitor. For us to properly isolate this issue, we have some questions for you:

• Are you experiencing the same issue even without using the Quicken tool?
• Have you checked if the display resolution settings of the Surface device and the external monitor is the same?
• Have you tried checking for a graphics device driver update?
• What troubleshooting steps have you done to isolate the issue?
  

We're looking forward to your response.
