i was wondering if i could use an HDMI on my dedicated graphics card which is currently running one monitor and plug in another HDMI to my motherboard where the integrated graphics is to run a 2nd monitor?
check in the nvidia control panel that your video card set to muilt monitor. with the known good monitor working see that the hdmi port on the video card is turned on and see if there a pc setting for your tv. if the min hdmi cable is not working pick up a dvi to hdmi cable if your video card has two ports. make sure you tell your local store your going to use the second dvi port as it has to be a different cable from the main dvi port.
