Windows 10: after sleep mode grey screen lines

hi, when trying to "awake" my computer from sleep mode, vertical grayish lines appear as my screen, turn off and on several times until reloads windows 10, how do I get rid of that screen?

:)

 

Screen showing grey lines

Screen on my laptop suddenly showing grey lines across the screen for a few seconds in Firefox browser and sometimes in mail. This is something new and suggestions? I run Windows 10 on my Dell Inspiron.

Thanks

 

Laptop screen displays jittering horizontal lines when coming out of sleep mode.

Problem description: My eighteen-month-old laptop screen displays
alternating horizontal lines and constantly jitters up and down when coming out of
sleep mode. The only resolution I’ve found is to reboot or let it go into sleep mode a
second time, after which, upon reopening the screen-lid, the problem clears and the screen displays normally. Any suggestions? Thank you.

 

sleep mode

Hi disgruntledWC,

There could be other settings on your computer that triggers your computer to go on sleep even though the sleep settings is set to never. To ensure that the sleep and display settings are properly set, I suggest that you look into the Advanced Power Settings.
Follow these steps:

• Open Control Panel and click Power Options.
• On your preferred plan, click Change plan settings.
• Click advanced power settings.
• Expand Sleep option, and make sure to set the following:

Sleep after : Never

Hibernate after : Never

5. Click Apply, then OK.

Please check also the screen saver option.

• Navigate to Settings > Personalization > Lock screen.
• Click Screen saver settings.
• Set your Screen saver to None.
• Click Apply, then OK.

Once done, please observe if your computer still goes to sleep mode after a few minutes of inactivity.

Looking forward to your reply.

Regards.
