Nitro AN515-58-5299 problems in some old games- horizontal black lines while playing some game

What is the exact model of your laptop, as this should not be happening on a new laptop with the screen, unless your old games are corrupted and are causing these issues, also allot of the fixes for this issue are not what a new user of a new laptop should be doing in changing parts, as that is an Acer service warranty matter, and you should consult Acer about these issues with a new laptop under warranty.

Here are 4 reasons and fixes why you are getting these horizontal lines:

1. Reboot Your laptop first when this happens in the old games
2. The old games might be causing these horizontal black lines
3. Carry out an update of the graphics driver to the last driver(s) e.g. Intel or NVidia or AMD drivers
4. Adjust the resolution of the screen
5. Replace the eDP screen cable (this should be done by Acer)
