Hello!

Yesterday my monitor started having weird scanlines that cover half of the screen and jag up the colors in a strange way. I tried changing the power cable and even turned it on without connecting it to the computer, and nothing happens.
Here's a video of the problem in question:
I really don't know what is going on, and I'm afraid I'll have to buy a new one. What can I do to fix it?

Thank you!

While on your current specs/system, did you try using another display to see if the system ended up with a dead/faulty GPU?

Speaking of GPU, what are the specs to your build?
I'm afraid the problem isn't on my build, since in the video attached, the monitor isn't plugged to the computer at all. It's only plugged into the power source. I have two monitors, and this problem only occurs in the one in the video. If that helps, I have an AMD Ryzen 5 2400G, Nvidia GeForce GTX 1650, and 8GB of RAM.
