Hey there. Sorry if I'm asking a silly question, but I've recently moved and as I've been getting comfortable with the place, I have a new HDTV. The issue is it only has HDMI ports, so in order for me to get a display via HDMI, I have to use it from my GTX 580. The issue however is my PC does not recognize any HDMI cable I put into the port, and I'm sure the port worked before as I used it at the old location. Does anyone know exactly on how to troubleshoot this? My only guess was the card came with a mini-HDMI cable that worked, but I believe I lost that in the move, and I know the HDMI cables I did use work, as they work for my cable and my PS3. I assume either the HDMI port on this thing is shot, or it's an issue with the cable. Since when I used it however, I did replace the motherboard, if that's anything to consider. I'm unsure if HDMI has to be enabled on the BIOS or not, but it didn't have to on my old machine. I figure I'd give you all a basic rundown of my situation, as I'm forced to use two HDTVs right now, with my new one getting no use at all right now.
