So I recently returned my RX 480 since it was faulty and I have my old GTX 650 ti inside my computer now. But now that I'm using HDMI input, there's a slight static on the picture for some reason. I've tried reseating the card, unplugging cables from both ends, etc. What could be causing this? I'm using a switch that allows me to switch between my PS4 and my PC so I don't know if this could be the problem even though I've had it for quite awhile now.
