Hi, I bought an LG external monitor and it's giving me some very annoying trouble when I'm using it with my Macbook Pro. I have a Moshi MD port 2 HDMI adapter and an Apple HDMI cable. The thing is when I connect everything, it works OK for some time and then I start getting this "rain" randomly. I uploaded a video on youtube so you can see it better. http://www.youtube.com/watch?v=3-WO9rY8_dU Any help will be appreciated! Thanks on beforehand!
