Apple adapter triggering 30-inch LCD errors?

updated 09:50 am EST, Mon January 26, 2009

Apple video adapter issues

Apple's recent Mini DisplayPort to Dual-Link DVI adapter may be causing problems with 30-inch LCD displays, complaints on Apple's support forums suggest. The adapter is mainly intended to connect modern MacBooks, MacBook Pros and MacBook Airs, which are currently the only devices that support Mini DisplayPort. Users of the adapter are reporting a variety of errors however, ranging from graphics corruption to temporary blackouts.

Although some Apple tech support staff are said to be claiming that the adapter will only work with the highest-end Cinema Display, glitches appear to be unrelated to brand, affecting Apple monitors as well as screens from Dell and Samsung. Apple's own product page indicates that the adapter should function with any 30-inch screen with a DVI port.

It is unclear if the adapter is directly responsible for errors however, as deleting the PLIST files and then resetting PRAM may diminish problems. The strategy is not working for everyone though, and it is not clear if and when Apple may have a solution prepared.

    might be "ok"

    I dont know, it will probably be ok. I got mine shipped to me late Dec and have been using it on my 30" cinema display. the only issue I have at all is that (for whatever the reason) it will blackout the screen for about a second or less. It does it randomly and when it does it it is only one time only it does it and seems to do it within about 5 mins of starting up.
    After that I can have the display running hours with it and no other issue at all arises.
