Connecting MacBook Pro to TV monitor?
I have a 2011 MacBook Pro, that I am trying to connect to a TV monitor. I have connected it before with same HDMI adapter and cables (been a few years). Upgraded to Yosemite system and now cant get to work. The TV monitor says no signal on the HDMI input channel. I believe the monitor is a 720 display. Any suggestions or ideas as to what I might try to get this to work?
