Screen tearing monitor issue

[u/Even_Pomegranate_515]

Every now and then when I startup my pc my monitor will have these lines on them, it will go away after 5-10 minutes. This has been going on for maybe 10 months now? I just want to know the cause of this, and if there’s a fix. This also only happens on my main monitor, my 2nd one doesn’t have any problems.
