Dual monitors won't "wake up" after sleep

Question

My laptop is set to go to sleep when not in use, but when I have it set to use Dual screens, after I "wake it up", all I can see is the mouse on the second screen, flickering. If I unplug the VGA cable, the laptop screen wakes up, and I can see the log-in screen. Once I plug the VGA cable back in, the second screen "wakes up" too.

This problem does not occur on startup, and I have set the second screen to be my main display - but I do often disconnect the laptop to take it with me. I have also changed the settings to make the laptop screen my main display, and the issue still occurs, just on the laptop screen instead.

This has only just started happening, around the time of the last update (2017-06 Cumulative Update for Windows 10 Version 1607 for x64-based Systems (KB4022715)).

Running Windows 10 Home, Acer Aspire E 15. Let mem know if additional information is required.

Solution 1

I had a similar issue with one of my dual monitors not showing up after resuming from sleep. I used the keyboard shortcut Ctrl+Shift+Win+B to restart the graphics driver and my main screen flickered off and then both screens turned on.

There's some more information in this question.

Solution 2

I found a simple solution I make sure that no monitor is using VGA. It seems that Windows 10 will "wake up" the Digital Monitor (HDMI/DVI/DP) but not VGA. I have had to remove the VGA connection on countless users computers to get around the problem.

I have tried to use the DP to VGA, HDMI to VGA and DVI to VGA converters but that does not seem to solve the problem. The monitor works correctly with DVI to HDMI, mini DP to DVI and DP to DVI.

Solution 3

Perhaps it'll be useful to anyone:

My unit is old Fujitsu P710, fairly standard business aimed, core i3 based pc. BIOS: Aptio Setup Utility | Code ver. 4.6.5.3

I fixed the issue with secondary monitor not waking up after exiting sleep mode by changing bios settings:

Go to Power tab: change "Hibernate like Soft OFF" value to disabled.

Save & exit.

That's it. Problem went away in my case.

Solution 4

disabling the display driver that is not working and enabling again in the device manger worked for me . it caused my screen to flicker for 1 time but it worked .

hope it helps

have been searching all over in the net for answers.

Here are some troubleshooting steps that may help in solving that issue.

• Open Power Option and click on Change plan settings then Change advanced power settings.
• Expand Hard disk then Turn off hard disk after and set it to Never.
• Expand Allow hybrid sleep and set it to Never, set Hibernate after to Never as well.
• On Power Option main menu, on the left pane click on Change what the power buttons do.
• Once open under Shutdown settings remove the check on Turn on fast startup then click Save changes.
• Also do disable the screen saver mode of your PC when it idles.
• Next is to do a clean install of your graphics card driver as well.

I've done all but the fresh install of the GPU, and the problem is still occurring. It also appears that the windows update system is trying to install the same driver, over and over. So I'll try the fresh install and see what happens.

Welcome to Super User. Just a guess, but the OP probably would not be using VGA if those other connections were possible. :-)

Great! It works for me.

[Sergеу Isupov]

In fact, it worked only once

I'm encountering this issue with a VGA cable plugged into a DisplayPort with an adapter, so you might be onto something.

I've installed graphic driver. But after restart, my second monitor is turned off whenever lockscreen appear on primary screen.

[sobelito]

Did not work for me. Had to reboot.

Hah, this worked, but it turned on my laptop screen too, and reset all orientations.
