My pc screen goes black when I move my desk (randomly)

[remote grove]

Hey there, I have an issue with this, my problem is when I make a hit (even if it's strong or mild) my screen of my pc turns black, but the windows and the entire pc still working cuz I can't stop listening the music and the windows sounds when this happen, I've checked my GPU cables and is fine, I know is fine cuz when the GPU cable is too stretched a red light appears but when this happen that light is off, anyone knows what could be? Is weird for me because even if I hit my pc now doesn't turns black, this is random

sounds like it’s just losing image so maybe it’s the display cable

I've checked it with another cable and still having this issue

did you try a different type of cable?if you have a movable desk for sitting and standing, it's possible the ports on the GPU or the display could be having an issue with metal contacts within the ports themselves, because of strain from the display cable pulling and bending the ports
