I have a best buy brand tv Hiteker that I am trying to output my PC to. When I try and extend my desktop to TV through the windows 7 control panel it errors with cannnot save settings. When I try and do it via the AMD Catalyst control panel TV tries to connect but displays not support. I cannot change resolutions as it's all greyed out. I have 2 monitors connected via DVI that work fine. I have tried disconnecting one but get the same error.
Thanks for your help.
