Have an old 23" cinema display purchased in 2002. It is the one with the polycarbonate case and one input wire with a male plug. I believe the plug is a DVI-D, it has 24 pins and one horizontal blade. Am I able to use this as a TV? I have a verizon fios HD DVR with HDMI and s video. I see I can get DVI-D to HDMI adapters but I'll bet that is just too simple. Also, I will still need something to get audio. So, two questions, is it possible or would it be cheaper to just buy a TV ?
