I've tried reinstalling graphics card software, every resolution from lowest to highest setting, disabling audio frequency through the dvi-hdmi connection to avoid video interruption, changing aspect ratio on my TV, swapping hdmi ports on tv and swapping between the two dvi outputs on my graphics card. I've left the TV and computer unplugged for 24 hours for a sure hardware reset on both. I've been digging through countless forums and have tried known possible solutions. I cannot see if the LG TV is HDCP compatible because I cannot see a display. I've rolled back to older software updates on the graphics card because I previously was able to use the 42'' LG TV as my display before this update occured but still no luck. I don't have another dvi-hdmi setup to display two monitors at once, I have it currently hooked up to a 32'' samsung which is working perfectly on any possible setting, both TVS are full 1080p capable. The TV recognizes the HDMI ports being used as it goes from NO SIGNAL to INVALID format on all settings. I am looking for some much needed advice please help me.
