When I go full screen when in extending mode and playing videos, why do I get solid green screens? It appears to have occurred when I updated my Lenovo ideapad 130S-14IGM to Windows 11. I really don't need the 11 version. Would it be best to just go back to windows 10? If so, HOW?? Not a computer person.

Green screen

Hi Nancy,

The issue you are experiencing may be due to a corrupted software or a hardware failure on the computer. However, we need to perform some troubleshooting steps to isolate the cause of this concern. Before we proceed, may we know the following:

• What were you doing when you encountered the green screen?
• Did you make any changes on the computer prior to this problem?
• What troubleshooting steps have you tried so far?
• Are you also getting any error messages when experiencing the green screen? If so, can you send us a screenshot?
  Note: Please do not include any personal information.

 

Extended screen with wndows 10

I have a new HP laptop and an LG external monitor and want to extend the screen.
As a starting point, I tried to extend the screen just using the laptop and the monitor.
I pressed the windows icon and "P".
Four options appear. "PC screen only", "duplicate" and "second screen only" all work.
However, "extend" option appears not to work.
The monitor has the expected image (if a website is opened) and an operational mouse pointer. However, the laptop screen shows none of the webpage and shows only the wallpaper image present when the device is turned on. The mouse pointer can be moved between screens.
The web page is certainly not extended across two screens.
Any suggestions?
Thanks Michael.

 

green screens

Since I upgraded to windows 10. I'm getting green screens on IE, Firefox, Microsoft edge videos and on some movie apps. But not on Google Chrome.I have tried all the community step by step suggestive, instructions. But the problem is still there. I understood
that Microsoft is having some issues with windows 10. Is that a fact? .
