Hi, I'm using a minidisplay port > VGA to connect my macbook to my HDTV. The thing is, the image gets all fuzzy, kind of shaky. then stops. This goes on and on. I've tried disconnecting everything from the laptop, even the power cable, thinking it might be interference, but nothing stops it. The TV works fine with other computers connected, and the VGA adapter works fine when i connect the computer to another screen. Any ideas? It's giving me headaches, i can't watch anything!
