Right from the start, only left display was working. After trying different usb ports, updating bios, drivers for usb, and reseating hdmi cable to rift and gpu, black block appeared on the left screen. Now i can only see little from the edges of the display, and even that is shown in purple. Rift is connected directly to hdmi port Pc: Asus maximus hero VIII, Win 10 i7 6700k, Asus strix 980ti
