I had to replace the video card because they wore out the HDMI port. Ouch.
I recently got a new hdmi cable and it will not display my computer on my tv. The old one that I just had to get rid of worked fine. I plugged in the cable to my xbox just to make sure it wasn't a faulty cable and sure enough, it worked with my xbox. Ive tried just about everything I can think of fn + f8, connect projecter, changing resolutions, shutting both off and starting each seperately, etc. If anyone has any idea why this cable wouldn't work with my computer while the other one did just days ago please let me know.
