    Hi there!
    I recently bought myself a mini display port/ Thunderbolt to Hdmi adapter and tried to connect it to my TV via HDMI port but for a moment there's info RETRIEVING DATA and then NO SIGNAL. I tried even with changing resolution but no good. In System information in the field Thunderbolt it says that 'no device connected'. I even swapped HDMI cables but nothing works. Mac and Tv don't see each other. :confused: Any ideas?
