I have a 24" external monitor (HP LP2475w). With my old laptop (PC) this monitor worked perfectly. Now with my new Macbook Pro (10.6.1) this external monitor flickers about every 15-20 seconds. The flicker is extremely fast and seems to just be entirely white. The monitor is connected by DVI-DVI. One important thing to note is that this monitor, when plugged into my old PC, was plugged in via VGA.
Any ideas about how to get the flickering to stop? I've tried using a different mini-display port adapter and a different macbook pro to no effect.
