I was trying to connect my external display to my 13" rMBP (OCT2013) last night, but I couldn't get it to work. I would either get black blinking or constant snow. I switched the external monitor resolution to 720p, and it finally got a stable picture. I tried watching a show, but there was still static present on the left and right black bars (the show was in 4:3).
What's going on? This is my first Apple computer, and I've never run into an issue like this before on a PC. My girlfriend uses the same monitor on her older Macbook using displayport-to-HDMI, so I don't believe it's the monitor. The HDMI cable should be fine as well.
