Hi, I have a 42pfl4606H/12 philips television (software version TMP71E 2.22) and i am trying to connect it to my new computer with an AMD Radeon 5450 HD video card via an HDMI-HDMIcable. I've tried all three HDMI ports on the television and different resolutions but i cant get it to work. The computer does recognize the television and says in the display managment screen a phillips FTV is connected. The television stays black though and tells me it has no signal. I tried connecting the computer to a different screen via the same method and this did work, so it must be a problem with my philips television. I really dont know what to try next so i would appreciate some suggestions.
