HI, okay well I have a hp laptop computer and a Panasonic tv and I have been trying to connect them together with a hdmi cord, but it does not work, there is no picture or sound. the display came on once for a second and then went off with a few black lines running over the screen, as if the cord was beening pulled out. I thought the cord may have been faulty so I brought a new one but still nothing. can someone help me please???
a friend said that the problem could be in the computer settings?????
