    Doesn't work!

    • Written by from Waxhaw

    Plugged it in to my MacBook Pro with my 30" Cinema Display, worked once only with flickering results. Apple doesn't seem to be interested in resolving this faulty issue with this product. Very sad.

    Works enough.

    • Written by from Herriman

    Connected successfully to my third party monitor (Samsung SyncMaster 220WM). Although, when display wakes up from its "sleep" the resolution is all wrong and cannot be changed; computer must be restarted to use correct resolution. Apple support could not help me resolve this issue so I disabled my sleep settings.

    If I don't let my displays sleep there is no problem. I prefer this solution (because of performance and price) to my easily breaking, Matrox multi-screen device.

    Works like a charm

    • Written by from chicago

    Using this product I connected a circa 2008 30" HD Cinema Display to a brand new 27" iMac quad core with Intel I7 processor and ATI HD Raedon 5750. The 'install' took about 90 seconds, and it worked perfectly from the get go. I suspect those reporting of flickering or diminished quality are running on insufficient processsors and/or video cards.

    Flicker Issues on Black/Dark Backgrounds

    • Written by from Clifton Hill

    Like a lot of people, I too am experiencing green & blue flickers on black/dark parts of the screen when connecting my brand new 15" MBP to an Apple 30" Display. I had hoped this wouldn't happen to me with brand new equipment but there you are...

    Expensive & Made my 30" Cinema Display unstable

    • Written by from NORTH HAVEN

    For the price I would expect good quality, but no. The screen flickers and render my cinema display unusable when the 30: display is already very unreliable.

    I just have to deal with the flickering forever.

    no troubles here -- "It just works"

    • Written by from Logan

    Connecting 13" MBP (2009, OS 10.5.8) to 30" HD Cinema Display. Plugged it in and it works.

    I do notice occasional flashing lines on a black background (on the cinema display only), but that's it. I'm very pleased. I had no idea I'd be able to drive a monitor of this size with my MBP.

    Sweet!

    The problem isn't this part, it's your DVI cable

    • Written by from Vancouver

    I have the pleasure of working at a company that gave me a 30" monitor, and right off the bat this adapter worked perfectly.

    When I moved to a new desk, I moved everything but my old DVI cable. Instantly I started to experience the flickering and snow problems described here.

    Ran back to my old desk and grabbed my old DVI cable, and it solved the problem.

    If this adapter doesn't work for you, try a different cable.

    Mac Pro with Radeon HD 5770 card and this adapter

    • Written by from State College

    The Mac Pro Radeon HD 5770 card has one dual link VGI port and two mini display ports. It can carry three screens.

    I have one carrying three Apple Cinema 30 in displays flawlessly.

    However the mini display ports are NOT LIKE THE ONES in Mac Books.

    VGI and DVI screens - even small - don't work if connected with a cable adapter to the mini display port.

    Every VGI and DVI display (any other than the new ones with the mini display plug built in) NEEDS THE $99 Mini DisplayPort to Dual-Link DVI Adapter in order to work with the mini display port, Apple just confirmed to me.

    With 2 of these adapters there are no problems with 3 screens/card. The adapters are powered though their USB cable so plan on an USB powered hub as well.

    unreliable, way overpriced

    • Written by from Boulder

    Non-stop problems, as others have experienced, with snowy screen and flickering, especially when coming out of sleep mode using this adapter and a Dell U2711. Found a mini displayport to displayport cable that works flawlessly for a fraction of the price.

    No problem with a Dell 3007 WFPHC

    Contrary to some of the reviews I've read about this adapter, I've had no problem using it between a MacBook Pro 2009 and a Dell 3007 WFPHC. I don't notice any flickering and I've haven't lost video.

    OMG...!

    • Written by from Fort Myers

    Okay...Here it comes:
    This is the worst disappointment of all time.
    The Dual-Link DVI Adapter is an absolute failure by Apple in my opinion.
    Being quite the Apple nerd, I was certain that I could get it to work....NO...!
    It didn't work....I faced a barrage of problems: Screen flicker, video drop-outs, noise.. Finally just nothing at all. ZERO. Why Apple would take away a perfectly good DVI port on their MBP, and put this pathetic low-power mini-display port in, is beyond my understanding. The DVI port worked perfectly...PERFECTLY...I could EASILY drive the 30-inch monitor from my "old" MBP. Then..I buy a brand new MBP (with a mini display port) and it's a step BACKWARDS. Shame on you, Apple. You must have KNOWN that this wasn't going to work...why in the world would you EVER sell a band-aid for a hundred dollars...? You can drive a 23" inch monitor fine...by using the mini-diplay to DVI pig-tail plug. No prob. But I hope no one else goes through what I did. Tearing out an entire system out of office furniture...wires and plugs, etc..to put this thing in...all excited about a big, rich 30" screen. Now I have to tear it all out, and go back to 23"... Sorry Apple...this ranks worse than the reception problems on your iPhone 4....which I also own...when did it become okay to do this to your customers...? You are suppose to be different from all the others. Now it seems you're cutting corners....sad.

    works as advertised

    • Written by from Tucson

    I've had this adapter for about 2 weeks now. Contrary to what its name implies, it does NOT allow you to use it to drive two displays, though that's what I am doing with it by means of a second piece of hardware: Matrox TripleHead2Go Digital. Every time you attach two active adapters together, problems are bound to follow, and I do have problems waking my displays from sleep (I need to power-cycle the Matrox box to do that). Still, for an unsupported configuration, it works quite well.

    My adapter has firmware 1.3. People around here complain it does not solve the problems with firmwares 1.1 and 1.2, but that has not been my experience: I do not see noise in black areas. I do not see distorted graphics. I do not see odd lines on my displays. Neither of these is also a problem when I run QuickTime or iTunes. Pixel-wise I am driving slightly more pixels than what your average 30" display has, so I am pushing this adapter close to its limits.

    My complains are the following: (1) compatibility with my video extender (I wish). (2) price: this is effectively a $80 fine for running decent graphics! (3) design requiring this adapter be powered through a USB port on your laptop: show of hands, how many people enjoy being able to cook eggs on their keyboard? (4) USB port on the face of the adapter is drained of virtually all power, so nothing works off it.

    Works for nVidia 3D Vision

    • Written by from Woodland Hills

    Using this Dual-Link DVI adapter with my 2010 Macbook Pro (Core i7 + nVidia GT 330M) allowed me to use nVidia 3D Vision under boot camp with Windows 7. The regular DVI adapter is only capable of 60hz output, but under boot camp this adapter will allow a 120hz output from the GT 330M thus letting 3D Vision work. I primarily need 3D Vision in order to view stereoscopic visual effects footage for work and was thrilled to discover I could do this with my existing Macbook Pro. I'm using the Asus VG236H monitor and it works perfectly. I also fired up Portal just to see if it would work in 3D vision and to my amazement it ran well in 3D even under fairly high settings despite the fact that nVidia's system requirements state you can't do this.

    Unfortunately, I have to deduct a star as I'm unable to output 120hz to my Asus display under Mac OS X with this adapter. It shows options up to 75hz but they are all greyed out and the only mode I can use is 60hz under OS X. Windows 7 will allow you to use the full 120hz.

    Flicker, flicker, flicker.

    • Written by from Chêne-Bougeries

    I have read all these reviews and decided to give it a try (I have Samsung Syncmaster 305T+ 30" display). People at Apple Store told me if I got any problems with the adapter, I can get my money back. At first, it worked more or less OK (the image was scrambled occasionally, but turning display off and back on via Hot Corners solved the issue). Then, Snow Leopard graphics update happened few days ago (or was it the EFI update?), and it started to FLICKER. Several times per day, for 20-30 minutes. That drives me completely mad; I having headaches, and if I had epilepsy, I would immediately got a seizure. This is insane, and if Geneva Apple Store doesn't solve the problem, I will do something awful, I swear. I need my 30" display, I can't work without it.

    Flickers with 30" Cinema Display

    • Written by from San Francisco

    I just went to the Apple store to swap out this cable due to flickering (the service there was great). Unfortunately, the swap didn't help. Unfortunately for me, this means I need to buy a new monitor if I want the flickering to stop. (From a troubleshooting standpoint, the monitor works fine with a direct DVI connection, and I've plugged 3 different laptops in with the same results, so I'm confident the issue is with the cable.)

    Mine works perfect and have no problems with my Apple 30 inch display. Reading all the reviews almost kept me from purchasing this spectacular display as I am using it with a unibody Mac Book Pro 15 inch. Maybe the new firmware fixed the problems?

    Weird behavior

    • Written by from Albuquerque

    So setup - Brand new Mac Mini, Brand new 30" LG W3000H, Brand new - Dual link mini display port adapter. Random flicker, pink noise on the screen, blurred blacks (blue flicker). Tried with different DVI cables, different power cables, different power sources (i.e., wall vs UPS), all with similar but different problems. Plug the screen into an old MBP with full size DVI, no problems at all.

    So, I tried to plug the display port adapter into another 30" screen, 2yr old Samsung 305T. Looks great.

    I have suspicions that some monitors will work, and that some won't after this. However, I am going to blame the adapter for being quirky. For a $99 piece of equipment, I would like to have seen better performance than this. Basically, my new monitor is useless with this display port adapter. I'm transitioning to a linux box with a dual link DVI graphics card in it. Sigh.

    Lasted almost five months

    • Written by from Sandy

    Worked fine with an HP LP3065 monitor, for a while. I was banging away at a document earlier this week and the screen went black. Thought I heard a very quiet 'pop' so I assumed it was the monitor. Not so. HP's trouble shooting revealed that it hadn't dropped dead. I connected the Mac to another monitor via another adapter. No problems there. Then I envisioned that call with Apple about this $99 adapter, then obviously the culprit. Is there another one you can try? Nope - this is the only $99 accessory that I have ever needed for connecting a computer to a peripheral device.

    I bought another one from Amazon. If you have a dual-link DVI monitor, you really don't have much choice but to shell out for this thing. Plugged it in (after checking one more time to see if the old one had fixed itself) and sure enough the replacement solved the problem. I called Apple then, and at least they are willing to ship a replacement, to arrive in 2-5 days. I guess I'll have a spare.

    Given the hassle I wish I'd sought an aftermarket mini-DVI compatible monitor (not that there are many of those). Apple really needs to examine its perspective on video ports. If the designers are going to demand an adapter, and Apple is going to charge a whopping premium for it, it should at least be a quality product.
