Hello,
I'm facing an issue with my AN515-55 laptop. When I turned it on, the screen displayed horizontal lines, and half of it went black with lines. After two attempts to restart it, the problem was resolved by itself. However, a day later, the same issue occurred again. All my drivers are up to date, but when I turned it on at 60 Hz, everything went fine. Do you have any suggestions on how to get it back to 144 Hz?

"By the way, my warranty has expired."
Thanks in advance.
