My MacBook Pro deteced it as a display "SyncMaster" right away, but the display is simply black with a flashing green light by the power indicator. When I unplug the video input from the back of the monitor, it says "no connection, check signal cable", so i know the monitor isn't simply dead. I'm using the DVI-VGA adapter with a belkin vga cable to connect it. I've also tried with a completely different adapter and a completely differen't cable. same effect. any ideas? thanks!
