I have a Panasonic 42 inch flat screen plasma tv. Is there any way that I could hook it up to my PC so that I can use the tv as a monitor. I have an Acer computer (with HDMI port) and I have tried running a HDMI cable from the PC into the TV but can not get it to display. I have made sure that the tv is set to the right port and even told the computer to look for a secondary monitor, but still to no avail. Anyone have any ideas please. I have a Integrated NVIDIA® GeForce® 7100 graphics card if that helps. many thanks
