I was trying to watch the last episodes of Breaking Bad in preparation for tonight and tried to use the HDMI out for the first time. I don't know if Im doing something wrong, but this is what happened: Computer was on. Plugged into tv. Screen flickered like it noticed the display but nothing came on TV (said no input device detected). Hit "detect displays" to no avail. Restarted computer. TV showed display but macbook display was black. Started playing the show but audio would only come out of macbook (I checked audio output setting on computer and switched them to SAMSUNG). Unplugged and then plugged back in HDM cable. Worked fine. Any thoughts?
