Question My monitor stopped showing picture through DisplayPort after I turned Freesysnc off ?

Jan 9, 2022
I was just playing minecraft on my computer and decided to take freesync option off mid-game. My monitor turned black. It did show black picture and detected my siplayport but couldn't show picture.

I'm using a used gtx 970. Is it possible that the displayport stopped working now? And could there be a fix to this?
