I got my rift over a year ago and it worked just fine for the first two or so months. Out of the blue, the software said that my HDMI cord wasn't plugged in even though it was. I have made sure it isn't a problem on either end of the cord, tried countless online remedies, and contacted several different companies to no avail. I need help with this because I can't afford to just buy something else. Also, it isn't a broken cord or port because the HDMI port works with other cords and I have bought a replacement to the headset cord already. Any suggestions?
