    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.

    I've been using this cable with my new 15" MacBook Pro and an HP3065 30" display for a couple of months now with no problems whatsoever. Works perfectly.

    No problem with a Dell 3007 WFPHC

    • Written by from Gilbert

    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.

    flicker and other issues

    • Written by from Raleigh

    I have a MBP w/NVIDIA GeForce 9400M/GT video cards connect with this adapter to an LG W3000H. The monitor flickers, and if I turn my monitor off, when I turn it back on, I see the image, but it's snowy (very hard to see). I have to unplug the mini displayport, wait a few seconds and plug it back in.

    From system profiler, it looks like I have version 1.01. I plan to go back to the apple store to try to get version 1.03 which folks in this forum suggest fixes many issues.

    Does anyone know if we order directly from apple, if it's possible to get fw v1.03?

    1.3 is garbage too!

    • Written by from Parker

    I just went to the Apple Store, had them open the package and connect it to a computer to confirm the latest firmware 1.3 before I left the store. The Apple Store employee told me that they would sent any old units back to Apple, and they only sell the most up to date version.

    I take it home, and try connecting to both my 2009 Mini Mac AND my new 2010 i7 MacBook Pro. Same thing as everyone else. In the black parts of the screen there are white flashing lines. It looks like garbage, and I will be taking it back.

    I have a love/hate relationship with Apple! My 30 Cinema display looks great on my 2006 MacBook pro with Dual link DVI built in! Looks like garbage on all my newer macs. Thanks Apple!

    Flicker

    • Written by from Chanhassen

    Connected to the Cinema HD 30", to the iMac LED 27".

    The adapter works, but the screen has scattered horizontal flicker (graphical artifacts that last for, oh, 1/60th of a second) that is very, very annoying. Especially visible with a darker background.

    Disappointed. Gave the produce 2 stars instead of 1 star, because it is makeshift usable.

    One of the other posters said that they switched to using a powered USB hub and his problem went away. Tried using a Belkin powered USB hub, but that did not change the flicker issue.

    Firmware version 1.03. Hopefully the problem will get fixed with firmware version 1.04.

    Buy a powered USB Plug

    • Written by from Victoria

    I encountered the screen flickering issue mentioned by other users, but fixed it by getting a powered USB hub that I plugged the USB plug from the dual-link DVI adapter into.

    Because the dual-link adapter doesn't work properly without a separate powered USB connector, I give this product 2 stars. It's basically junk without the powered USB connector.

    Works great..price too high

    • Written by from Manchester

    I was nervous about buying this adapter after reading all the bad reviews before hand. I went for it anyway, and it works great. Using a Dell 30" 3007WFPHC monitor, with no picture problems at all. It's as sharp as anything.

    Please ensure you have a DUAL LINK DVI cable...not a normal DVI cable as the adapter then causes problems. I didn't realise the first time round when I plugged in my normal DVI cable.... just make sure it is a DUAL LINK version.

    Too pricey... for what it is. Hence the 4 stars

    Horrible

    • Written by from San Jose

    Many issues with this adaptor. My 30 inch display works fine with my MacBook Pro and a WIndows 7 PC but with my Mac Mini (mid 2010) no go - constant flickers, blackouts and the display flashes a "video not supported" error. Lot's of turning off/on, disconnecting, etc.

    Works as advertised. No problems here.

    • Written by from Ottawa

    As I said in the title, it works exactly as I'd expect it to. I have a 27" iMac that I wanted to drive a secondary 30" Apple Cinema Display. I'm getting full resolution from both screens. 57" of work space and loving it. Absolutely no issues.

    A little less expensive for an adapter would have been nice. I also bought the regular MiniDisplay to DVI adapter first and Apple should call out the fact that those won't drive a 30" display a little more blatantly on the site.
