- MBP 15" early 2011, 512G SSD, 16G RAM ,2G- i7, OS X 10.8.5
Trying to mirror my MBP screen to external Acer monitor using miniHDMI connection to HDMI. It used to work at 1080i, but now will only work at 720i, which is too big for screen and not detailed. At 720i the external monitor works but the MBP blinks and flashes on and off.
