Hi. I have a Sapphire Radeon HD 5670 video card on Windows 7 Ultimate 64-bit. I am using my monitor with the DVI port. I wanted to add my TV to the set up as an additional monitor to increase screen estate. I connected it with a HDMI male to male cable. However, my system does not seem to detect the monitor and there is no display on my TV. On hitting the detect button, it shows me "Another display not detected". Even when I unplug my current monitor and keep only the TV plugged into the HDMI port, I can see no display on my TV. This is the first time I have tried to use a TV in a dual monitor set up so I am not sure what I am doing wrong. Can someone help me out?
