hi! I recently had to use the small pinhole on the back of my Acer predator triton 500 to fix an issue with my computer switching off when unplugged.

after resolving that issue I noticed there are now 3 small horizontal lines at the bottom of my screen.

I have checked my BIOS and deduced that it is NOT a hardware issue, so what do I do now?? my NVIDA GeForce drivers are up to date and so is everything in Device manager, what do I do next

    Hello!!

    @RothmanRed

    We need to determine whether it is a hardware or software issue..  Turn off the computer.  Tap f2 while turning on the computer.  It will go to bios.  Please stay on the bios screen for 30 mins.  If the display is looking good on bios then it is a software issue.  If the display is not looking good on the bios screen then it is a hardware issue.  


    If it is a software issue try the following the steps..


    Try windows x 

    go to device manager 

    expand display adapter

    right click on display driver - uninstall 

    Restart the computer 


    It should work fine.. 


    If it is still not working 

    Uninstall the display adapter from device manager 

    Don’t restart the computer. 

    Go to support.acer.com 

    chose your country 

    type snid or chose your model 

    go to drivers 

    Install the display driver 


    It should work fine..
