Mini DisplayPort to Dual Link DVI Adapter Fix (Temporary)

The Mini DisplayPort to Dual Link DVI Adapter for the new aluminum Macbooks and Macbook Pros is getting some bad press due to sporadic flickering problems. There are seemingly very few people who aren’t having problems, myself included. This is a strange move by Apple. It seems unlikely that this could go unnoticed in testing given the amount of people who are experiencing problems.Most people experiencing the problem have been unplugging and then re-plugging the usb part of the cable. This works but is kind of annoying to do and doesn’t seem to work for a long time — you do have to reboot eventually. Keeping the USB part hooked up to an external (powered) usb hub seems to lessen the symptoms but not alleviate them entirely.Another option that I’ve found works is to go in to System Preferences and then Display Preferences. Change your resolution to 1280×800 and then back to 2560×1600. That’s been consistently working for me for a few hours at a time.Other than that I’ve had a good experience with the adapter. The regular MacBook drives the 30″ display just fine — exposé and spaces are both as zippy as when not hooked up to any external display at all. In case anyone is curious, I’m hooked up to a Dell 3007WFP-HC and having the extra screen real-estate is fantastic.Update: Pressing Ctrl + Shift + Eject seems to work as well. This puts the displays to sleep. After sleeping you just move the mouse and everything wakes up and works. Your mileage may vary, but please let me know in the comments if it works for you.Update 2: Some people are reporting that Apple is retroactively saying that the adapter is only compatible with the Apple 30″ cinema display. I find this pretty unlikely for the following reasons:
  • It’s a standard.
  • Apple hasn’t updated the MacBook page to reflect this.
Again I’m pretty sure that this can be fixed via a software update since the above two “fixes” seem to work. I’ll post again when Apple updates.
