Mini DisplayPort to Dual-Link DVI Adapter

It's not the $100 adapter, it's your $2700 computer

Written by WS from Redondo Beach

Feb 5, 2009

I have both a MacBook Pro and a MacBook. The adapter works great on the MacBook and lousy on the MacBook Pro.
On the MBP it flickers and loses sync on a regular basis.

Also consider that it uses a USB port for power. Granted, there is a pass through port on it, but that can't even run a keyboard/mouse.

I don't know what Apple's said (can't find anything), but I've read that the problem could be the USB power regulation. Meaning mainboard. Meaning good luck getting that fixed.

Still, it's better than a PC any day!

This adapter is broken. It should have received more testing.

Written by AB from miami

I have a Dell 30" 3007WFP monitor that I bought for 1300 bucks over a year ago.

It works flawlessly with my desktop computer but has several problems with my unibody macbook. Periodically, the image will get either ghosted and weirdly broken (as many have reported) or the colors will become all wrong and there will be "snow" all over the screen.

Both are fixed by unplugging the USB connector of the Adapter (apparently it's needed to power it for some reason) and replugging it. I'm not returning the accessory for now since there are no alternatives and I'd rather live with the bugs than not be able to use my 30" monitor.

And the price is outrageous as well. I admire and love many apple products but this is certainly not one of them. Apple should have tested it more thoroughly and fixed the bugs.

Not working with my Gateway XHD3000

Written by AT from HELSINKI

Feb 2, 2009

The adapter did not support the full native resolution (2560x1600) of my Gateway XHD3000. No reason for me to use this adapter, so I returned the product. Very disappointing as this was the primary setup I was planning to use.

Got a Fix to the Flickering Issue for MacBook Pro

Written by MB from Boulder

Feb 1, 2009

Had the same problem that everyone else seems to have, but got a fix from the apple store:

For the MacBook Pro (15", unibody)

1) Open System Preferences
2) Open Energy Saver
3) Check the button for Higher Performance.

The issue disappeared and everything is working fine now.

FIX FOR 15" MBP

Written by GD from Arvada

Feb 1, 2009

If you change the graphic card settings in system preferences under energy saver to better performance from better battery life, we found the flicker to disappear. This changes the graphic settings from the 9400 card to the 9600 card. Thanks

Not an Apple authorized fix, just a customer trying to make the community happier by offering this suggestion to a problem.

Unreliable with External Displays

Written by GH from Charlotte

Jan 30, 2009

This does not work reliably. We have the new 15" Unibody MacBook Pro and a 30" Dell Monitor, which works great with the old style MacBook Pro. However, with the new required adapter the screen fuzzes. Wait until the adapter is reliable to purchase this or the unibody MacBook Pro 15".

It works, but...

Written by PB from Oakland

Jan 30, 2009

I have it attached to my 30" Apple Cinema HD display. I don't get any flicker and the screen always comes up, but any areas of the screen that are completely black display a rapid faint flicker of horizontal lines (think film noise). It's subtle but definitely noticeable.

I'm on the fence about returning it.

Mini DisplayPort to Dual-Link DVI Adapter

Doesn't work

Written by MD from Morgan Hill

Jan 28, 2009

Like so many others, this adapter does not work for me. I get a constant flicker that will not stop (unlike the occasional ones others have complained about). I have tried plugging it into both an Apple and a Dell 30in, both with the same problem. I have tried a bunch of the workarounds listed in the forums to no avail. I've tried this with 2 separate adapters. And of course, I tried them with a colleague's MacBook Pro (he got his about a month before me) and it works fine!!!! So I don't know if it's the adapter, the computer, or a combination. But in any case, now I have to keep using my Lenovo Vista machine to do any real work until this is resolved. I'm a designer constantly in the Adobe Creative Suite and I'm not willing to go back to 1440x900 just to use this computer that doesn't work with the newest technology. Very disappointing. I'm anxiously waiting for a recall and replacement program.

$100???

Written by LL

Jan 26, 2009

You're joking me? $100 for an adapter for a perfectly good working and relevant 30" ACD monitor??!

Not to mention i cant use the firewire on the back of the ACD. and it barely works most of the time which is just the kicker.

I mean, its not that hard to create something that looks simple and elegant, but put some craftsmanship and quality into it really!

You have access to a multitude of Apple products in your factory, do a bit more grindstone testing before we pay the burden of failed products that dont get the quality assurance customers that are willing to pay for apples premium.

Good luck next time.

(dont get me wrong im not here to bash Apple at all, I'm just reluctant with all these quiet changes and no realization that customers are offered standards and are now being kicked high to adapt or get nothing)

Mini DisplayPort to Dual-Link DVI Adapter

Mostly works

Written by AS from Champaign

Jan 26, 2009

I was glad that it has a USB pass-through because I really didn't know how I was going to handle even one less USB port on the laptop. Still I need a hub because the 30" Applemonitor only has 2 ports.

As for the quality of the device, it works most of the time. Every couple of hours it will blink a blank screen for a fraction of a second. I can deal with that.

I really just want a 30" version that uses the display port natively and has more USB ports. But I'll have to wait and see if Apple makes one.

Doesn't work with the Apple 30" Cinema Display HD either

Written by KB from Los Angeles

Jan 26, 2009

I have an Apple 30" Cinema Display. I waited patiently for Apple to release this product, hoping the delay meant they were ironing out last-minute issues.

They didn't. When I connect the monitor either of the two 15" unibody MacBook Pro's in my household, green and purple noise flickers across the screen where dark colors are displayed. For example top and bottom when showing widescreen formatted movies. Or left and right when displaying 3:4 formatted videos.

I hope I just got a lemon. I am going to the local Apple store tomorrow to demonstrate that either the adapter is broken, or the mini display port on both my MacBook Pro's.

Really Apple?

Written by ND from Lakewood

Jan 25, 2009

Being a web developer and graphic artist I use a ton of Apple products and for the most part I really love all of them. However, this adapter is the exception. First off, $100? Are you kidding me? The price of this adapter is one thing, unacceptable. I don't appreciate having to pay an extra $100 to hook up my MBP when the old one had a DVI connector built right into it. You could have at least given me 1 adapter for free with the laptop. And then there is the performance issue, always reconnecting my screen because it just shuts off or randomly displays static.

This is very disappointing apple. Normally I hold you in such high regards, but this adapter is only one thing, that's a P.O.S.

Extremely disappointed with Apple

Written by SL from Urbandale

Jan 25, 2009

I bought a new 15" MBP about 3 weeks ago as a replacement for my aging MS box. I'm a software developer by trade so a majority of my work is done at a desk using a Samsung 305T 30" monitor (2560x1600).

Unfortunately, I didn't do quite enough research on the new MBP models - I figured that it would support dual-link DVI out of the box.

I was surprised and shocked to learn I had to spend another $99 to plug in my existing monitor. After reading the reviews, I was hesitant to even bother (I think this is currently at 2/5 stars on the Apple store). I went ahead and purchased it out of sheer necessity, hoping I'd have better "luck" than other reviewers. I have NOT.

I experience at least 3-4 instances each day where the monitor will suddenly go out of sync. Its a simple matter of unplugging and plugging the mini-dvi adapter back in, but it is very annoying.

Additionally, there's a noticeable flicker - especially areas that have gradient color fills.

I'm absolutely disgusted with this product given the price. It were $20, I'd have more understanding. But $100? C'mon, Apple. Fix this. And offer us free replacements ASAP.

It simply does not work

Written by OK from Wien

Connected the adapter to my 30 '' cinema display - every few minutes flickering, sometimes the whole screen goes snowy and distorted and I have to reconnect.

Thanks Apple for making such a great Pro-product!!

Colored streaks over dark areas with 30" cinema display

Written by JM from Los Angeles

Jan 24, 2009

I have two problems with my Macbook Pro, this adapter, and a 30-inch Cinema Display:

1. Very visible colored streaks over dark areas of the screen, especially black areas. This problems varies in intensity, but it's always present. I connected a coworker's MBP to my display and saw exactly the same symptoms.

2. Jumpy mouse cursor, at others have reported.

I suspect both problems are MBP issues rather than a problem with the adapter, but in any case, as this adapter is the only way to hook a late-2008 MBP to a 30" ACD, buyers beware. I am using this system for technical work, so for me it's a merely big annoyance, but if I were doing creative work, it would be totally unacceptable.

Apple needs to acknowledge the problem!

Fuzzy video sometimes

Does not work reliably. Getting fuzzy video, I have to disconnect and reconnect the adapter. My old macbook pro (with a DVI connector - so this adapter is not used), works perfectly everytime. Very disappointing.

Periodically the display goes awry and I have to reconnect

Written by WP from Snohomish

Jan 22, 2009

I am one of the many users who are experiencing what appears to be an interleaving issue of the DVI channels, from time to time the picture shifts and the image is unusable. I have to disconnect the adapter then reconnect it. I advise holding off purchase of this until Apple is able to resolve the problem.
