I've had a Radeon HD 7870 (Factory overclocked) GPU for a while now.
A problem I've been having lately, is that horizontal blue stripes and/or flickering dots appear on my screen (mostly in black colours).
I did some research on the net, and seems this is a common issue with this card, some kind of fabricage mistake.
I read before that this could be caused by an underpowered GPU.
My card requires 500V but I have a power supply of 450V.
Anyhow, when I replug my VDI screen cable, the problem is fixed.
When I take a screenshot of the blue stripes, it does not show them on that screenshot. I am guessing the problem is rather in my monitor then?
I tried a different cable, but the same issue occurs, and when I replug it, it also often fixes the problem.
What do you think?
Is the problem my GPU, my power supply, my VDI cable, my monitor?
I highly doubt it's either my card or power supply, otherwise replugging the cable wouldn't work, would it?
Thanks in advance!
