Apple's Mini DisplayPort to Dual-Link DVI adapter isn't adapting very well. There have been a numerous of complaints on Apple's Support forums claiming that the adapter has a fault. The new adapter is intended for the latest MacBooks, MacBook Pros, and MacBook Airs with their nifty new Mini DisplayPort. Forums users have been reporting errors ranging from blackouts, to graphic corruptions that look like something out the movie Jacob's Ladder.
Blame has been pointed towards the monitors themselves, wih claims that the adapter will only work with the highest-end Cinema Displays. Glitches are being reported on Apple monitors, as well as high resolution screens from Dell and Samsung. Apple's product page shows that the adapter will function with a 30" screen with a DVI port, but there are images and movies that say different.
It's not certain if this is the adapters fault, but one possible solution is to delete the com.apple.windowserver PLIST files and then reset the PRAM. This solution, unfortunately, hasn't worked for everyone. Apple has just released a NVIDIA graphics update that should hopefully fix the problem.
