    Hi ,

    First of all make sure your machine is up-to-date and recieved all lastest windows updates.

    Try the below steps ,

    Run a troubleshooter. Open Settings and select System > Troubleshoot > Other trouble-shooters and run the Video Playback and Program Compatibility trouble-shooters. If you get presented with any recommendations for other trouble-shooters, run those too.

    Update your device drivers. Check for driver updates for profiles associated with your monitor and screen.

    Change your monitor’s refresh rate. Switching to another refresh rate setting can help with lines and screen flickering.

    Calibrate your monitor. This process should only take a few minutes and can help optimize your monitor for use with your computer and its environment.

    Change the screen resolution. Whether using a Windows or Mac computer, try changing its screen resolution.

    Click on 'Yes' for the question on bottom , if youre happy with my answer❤️

    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..

    If the line is there also in the BIOS then we know it's a hardware issue and we will want to try and pin it down to the cable that runs between the motherboard and display or the display itself. If the line isn't there in the BIOS we know it's a Windows issue and as suggested a remove/reinstall of the graphics drivers will likely clear it up.
