Why is my display shows many small screen

Hi,

Try uninstalling the display adapter in Device Manager and restarting the laptop.

If you have Win 10 installed, right click on the Windows Start key on the left side of the Taskbar and select the Device Manager link.

If you have Win 7 go to Control Panel> Device Manager.

When you are in Device Manager, click on the arrowhead next to Display Adapters to open the list and then right click on the display adapter entry, then select Uninstall and follow the prompts.
