Weird red pixelation when tilting monitor

Monitor : Acer Predator GN246HLB
Cable : DVI (brand new cable)

 

The interwebs has literally given me 0 solutions and the people that comment about it have no clue either.. let me state very clearly that this is NOT a SOFTWARE issue. I got this monitor from a friend and he used it on a diff pc than mine and he has the same issue. It only happens when I tilt the monitor backwards a bit.

Half the screen will be covered in this red pixel stuff.
It seems like nobody has a clue about what is going on here.
Or how and if it can be fixed.

Any help here is very much appreciated, I figured if anyone this could be the place to find answers besides Reddit.

I suspect that tilting might cause bad contact for some cable of LCD panel.

Does it have any effect if you hold monitor from other spot when tilting it?

A few possible points of error:

Display panel itself

Cable from controller to panel

Display controller 

 

Can we get a video of this happening?

Here is the video, I don't know if that helps?
I don't really have the skills to open this baby up and see what's wrong.

Looks lot like some cable is slightly loose...

Though typical problem is more random vertical striping:

 

 

But that could be explained by LCD panel signaling being handled by one cable for left side and another for right side.

And right side cable being OK.

 

Any hope of fixing that more permanently would certainly require opening monitor.

A lose cable inside the panel then yeah? Because wiggling the DVI cable doesn't do anything.
I think it would probably be a bad idea for me to open it up myself without any knowledge right ? :P
