I have a 3 monitor display and when I came back from dinner 2 of the monitors would not display anything. A couple things I've noticed before and after might help diagnose the issue. Before, when I would walk in a certain spot right in front of my tower, on the floor, my center screen would flicker (center one is one of 2 no longer working). After no signal, I've noticed my computer randomly gets like 2 fps as it takes forever for my mouse to move from one side, of my remaining monitor, to the other. This doesn't always happens but maybe every 5 minutes.

One monitor is a dvi connection the other is a display cable connection. The 3rd, that is working, is a display adapter from a vga cable... so the display adapter plugs into the gpu.

I thought my drivers were out of date, they were, but updating did not fix anything

Here are my specs

My gpu is this however... I got something else than what is above

Does it sound like a cable problem, certain parts pop out of place? Or did my gpu or something else die on me?

If walking cases flicker that should be first thing addressed

this

meaning its some sort of connection

All of the cables were plugged in just fine. I even unplugged and replugged. So the cables sound faulty? Or could it be what it's connected to? I only ask because 2 displays won't display a signal not just one!

did you try moving around which cable is plugged into which port/monitor?

run speccy. I want to see your temps.

I personally would start with making sure theres no damaged cables in the tower.
You walking in front of it should have literally no effect on it.

So it was the cable after all. I switched out the display cable for an HDMI and now all 3 are working. Only reason I bothered posting was because 2 went out simultaneously which was rather disturbing at first. Now all 3 are working again...

Thanks everyone!

Doesn't explain why you walking in your room caused issues.

Unless floor sunk down in that area.
Cause then cable moves if tower moves

yeah I guess, must of been one real touchy cable or some real fucked up floors.
