Hey guys, I purchased a third party mini displayport to HDMI adaptor off ebay and I cannot get it to show an image on my Sony Bravia KDL-46W4100. I've tried all 4 HDMI ports, and each one allows my MBP to detect the Sony being there with its various resolutions/refresh rates. However, no display shows up on the TV. I've tried turning on mirroring, turning it off, restarting the MBP, turning off the TV, firmware upgrade for both, etc. but the TV still shows no input signal. The MBP does flick off and turn blue when it first connects to the TV or if I choose a different resolution, but again nothing on the TV. Also with the Bravia, it's not picking up my MBP as a "PC" in the lists of inputs. I've tried searching through the net and have found similar issues with other people but have yet to find a definitive answer. Thanks for any suggestions you may have.
