Hey guys. So I received my MacBook Pro 13" a few days ago. I started using my external monitor, because I wanted to watch some movies. I am currently experiencing some strange problems. Sometimes, the screen flicks. Sometimes it makes small grey dots around the screen. And sometimes, it even turns off the monitor for a second. Also, I run my MacBook Pro in clampshell mode, and sometimes when I wake it up, it goes to sleep right after entering password. Here's a video. I didn't touch anything except my iPhone during this one minute clip. http://www.youtube.com/watch?v=2-Z-86cEiT8 Here is a clip of the external monitor, when there's a dark background: http://www.youtube.com/watch?v=gS96ZdUcarA I am using the following items: Mini display port to HDMI cable (Black one, unaware of the brand) HDMI to HDMI cable (1M) LG Flatron W2361V monitor (Set to 1080p) All of the cables are firmly plugged in. The monitor turned off and on 4 times while writing this. As well as several flicks.
