I picked up a new to me toshiba regza tv today and came home and swapped it out with my old tv. I plugged my mid 2012 MBP into it using a monoprice lightning display to hdmi adapter, the same one I used on my other tv. The MPB recognizes that there is a display attached (shows display settings), but no image appears on the tv. I tried all 4 hdmi ports, 3 hdmi wires, 4 different resolutions, and two other devices. My xbox and old hp computer connect fine to the tv. Do you folks have any suggestions? Again, mid 2012 MBP, 16gb ram, 256gb ssd and 1tb hdd. Thanks!
