Aspire 7 (Model A715-75G) Display issue - Faded Edges and Screen

That looks like its how the caption on the desktop is and its not from your laptop, as if the screen is like that with such dominant edge fading then its either the VGA drivers from Intel or NVidia, or its a faulty eDP cable or the actual screen is faulty and needs replacing..

First uninstall the graphics drivers with DDU software and follow their guide as you need to do this in safe mode and then reinstall the gpu driers, if that doesn't fix the problem then you need to cheek hardware issues like the laptops eDP cable and its plugs at the screen and mainboard if its not damaged or broken in any way and then check the screen as that could be faulty and needs replacing, which should be done by an experienced technician that knows exactly what these screen issues are. Good luck and hope all this helps you out.

For the LED screen and to see which screen model your laptop has, install WiNFO64 and look in this software's Monitor section for the exact screen model that your A715-75G laptop has from the list below
