Hello I recently tried to hook up my new Mac Pro to my 50PC1R-TH LG plasma TV. Iused the Mac mini DVI connected to an HDMI cable which I connected to theTV HDMI port. Sound was through a separate audio cable. Sound workedgreat, but all I got on the picture was no signal. I tried duplicating themonitor and different sequences for turning on, plugging in, but nothing.I then tried the same to a different TV, Samsung LCD, and all workedgreat. Is there something different you need to do with the LG TV's? Thanks for your help!
