    New MBP and adapter, still poor quality over dark screen areas

    We have three older 30" Cinema Displays in our office, three new unibody MBPs (Sept 2009, latest 10.6 updates), and two new Mini DisplayPort to Dual-Link DVI adapters (firmware 1.02).

    With bright or strongly textured backgrounds, no problems at all, everything looks good, monitor stays perfectly in sync. When large black areas are on the screen and the adapters are warmed up, you start to see random red streaks appearing across the dark areas, reminiscent of the kinds of problems seen with bad analog VGA cables and older LCD displays. The easiest way to see it is to set your background to the "Lightning" image in the stock "Black & White" backgrounds. Let everything warm up for an hour or two and look closely at the dark areas at the bottom of the screen.

    With different combinations of hardware, we see the exact same problem, so it really seems to be a design issue. None of our older G4 and Intel macs with DVI ports have any problems with these monitors. Under guidance from the phone support folks, we've reset the PROM on the MBPs, cleared plist files, switched between performance and power-save graphics modes, etc, with no improvement except for brief periods between reboots when the adapters cool down.

    It gets quite annoying after a while if you are using applications with dark backgrounds. The apple staff try to be helpful, but more people need to call them and complain so that more engineering reports are filed; this is the only way to get this remedied. If you're one of the people that think that the adapters work great, please do the above background test and call in if you see noise.

    Apple has a great opportunity to show their high-end users some love here.

    Purchased a brand new macbook pro - 30" cinema display this adapter and it just plain stinks!

    I had the cinema display for the past 2 years running but using this adapter and the latest macbook pro 2.8ghz laptop I notice tons of feedback in the display.

    So bad that after 2 days I went back to my older 2.2ghz macbook pro.

    Apple please fix!

    Do Not Buy

    I own the Macbook Pro 17" unibody and a Cinema 30 display. I am running the latest firmware and Snow Leopard. I still get some distortion (e.g. sparklies) using this product. My only advice is to not buy this product. Honestly, this is the worst Apple product I have ever bought. I am happy with the rest.

    Complete garbage

    Too bad there is no option for zero stars.
    I read the reviews but this cable is the only option for large displays and the current generation of DisplayPort equipped Apple products.
    I have now tried two of these cables. One with the 1.01 firmware and with the 1.02 firmware. Both flicker, scramble the screen periodically, and cause rectangles to randomly flicker on and off (usually on the lower half of the screen). These problems exist on all the 30" displays that worked fine with my last 17" MBP, I want my built-in DualLink DVI back. Apple has made some of the finest desktop and laptop hardware I've ever used. They should be absolutely ashamed that this cable ever made it into production.

    Works great

    Bought the unit in when the new mac mini came out. Was version 1.01 firmware,
    Had the usual problems. Took it to the Apple store they exchanged it for
    a dual link 1.02. Everything was great, works great on MM and MBP.
    It had a rough start but Apple fixed it.
    Great product, great company.

    Intermittent horizontal lines, snow, noise on black...

    ... just like so many others are experiencing.

    Other issue is that waking up the MacBook 17" from sleep will result in the 30 inch Cinema Display to wake up first, causing that monitor to be the default controller/finder monitor (#1).

    Got this today and hoped I could drive my 30 inch samsung but the monitor goes black every 15 seconds for a second. Impossible to work on. Really disappointed.

    Firmware version 1.02 fixes the problem

    I bought this adapter 4 months ago for my MacBook aluminum (bought Jan 2009) and Dell 3007WFPHC 30" LCD. The adapter had firmware version 1.01 and had the same issues many users reported: intermittent flickering, color speckle noise, blurry text, and analog-like color "snow". I could fix issue temporarily by putting the display to sleep and waking it back up.

    Today I took the adapter back to an Apple retail store, where a manager gave me a new replacement that has firmware 1.02. The new unit has performed flawlessly over the past several hours. If you have problems and have firmware 1.01, see if a retail Apple Store will also give you a free replacement.

    Fyi, find your adapter's firmware version:
    Finder -> About This Mac... More Info... Hardware -> Graphics/Displays -> look for "Adapter Firmware Version: 1.xx"

    Rating: Start with 5 stars because firmware 1.02 works, minus one star because the adapter costs too much, then minus two more stars because Apple released the product without adequate testing, wasting hours of my time trying to get it to work and eventually driving around town to get a replacement. 5 - 1 - 2 equals 2 stars.

    Works great for me!!

    I read the reviews for this item, but recently purchased this adapter anyway (call it true faith in Apple) and it works great with my new 30" display and Macbook Pro. No problems, plugged it in and away we go.

    I am getting the proper resolution, and I love the new real estate that I have on my desktop. I did check and I have the new Firmware version 1.02, so I don't know if this is better than previous ones people might have been buying but I'm happy.

    Truly offensively bad

    I never, ever take the time to write reviews because I just don't have the time. I'll make my very first exception in the case of this adapter for two reasons:

    1/ This is the absolute worst product I ever bought from Apple (I currently own 7 macs, no less). It DOES NOT WORK. Or it works when it feels like it and only when it feels like it.

    2/ I have to restart my MacPro at least four times a day for it to see the second screen attached to this $99 non functioning device, so now I actually have time to come here via my laptop to help prevent other people from making the same mistake I did by buying it.

    It was bad enough to be forced into buying extra hardware because Apple felt like pushing their new standard onto us (What was wrong with two DVI ports?), but at least, at the very very least, if Apple is going to pull this kinds of forced sales tactics, please try and force-sell something that works.

    Stay away.
    It will complicate your life.



    PS: for the technically orientated people:
    -the screen attached to the adapter comes up garbled and unreadable about 60% of the time at start-up, no matter what I do.
    -100% of the time garbled if the screen is turned on after the computer is started.
    -60% of the time garbled if the computer puts the screen to sleep after a long period of inaction.

    So for example, if the screen goes to sleep, I most likely have to restart the machine for it to work, but then there is a strong chance that the screen will still come up garbled anyway, unless I get lucky that the adapter sees the screen fine that time.

    $99? Really? Wow.

    Not cool. Green sparkles of doom

    Started out working OK when booted to Leopard. I use the 3 week old (4GB RAM, 128GB SSD) Mac Mini almost exclusively in Windows 7. I get green sparkles on black areas on the screen. It seems worse when the machine is warm.

    I have flattened the machine and clean installed Snow Leopard. Now I get a black screen.

    I am running on a Samsung 305T monitor.

    $99 fail.

    Finally works with Gateway w.firmware 1.02

    Finally got one after hearing on the US Apple site that someone tried it on their Gateway 3000 with success. I can confirm that it does in fact works though there is no way to tell what firmware version is on without going into System Profiler->Graphic/Displays and scrolling down to the XHD3000 settings. Unfortunately you cannot do this at the Apple Store so had take a leap of faith that the unit I purchased was new stock.

    Also heard on the US Apple site/forums that the firmware cannot be updated remotely/on your Mac via software update.

    Apple has upgraded the firmware and improved the adapter.

    I purchased one of these adapters a few months ago and had nothing but problems with it. Recent reviews on this forum had improved, so I called Apple and asked it the adapter had been upgraded. After some discussion it became clear that the firmware had, in fact, been upgraded. The current version of the firmware is 1.02 and it works great!

    Since the firmware couldn't be upgraded electronically by e-mail, Apple replaced my adapter at no cost. The new adapter has solved all of the previous problems.

    Works fine with Dell 3008WFP SuperView 30Inch Monitor

    Like a lot of people I was dreading having to buy this adapter due to the bad reviews but when I hooked up my brand new Mac Mini with OS X 10.5.6 to my brand new Dell screen the adapter has worked flawlessly and continues to do so more than a week afterwards. I have no problems with flickering, noise or interference, it works great which is a big relief. My only gripe is that it is expensive therefore 4 stars.

    confirming flicker problem

    Most people who buy this overpriced thing complain of similar problems - it flickers every now and again (completely randomly) for half a second to a second. I contacted mac support and they got me to delete two specific files (forget what they were now) but that did nothing anyway. I want to exchange it but from what I've read over the net I'm almost certain the replacement unit will ave the exact same problem! its completely ridiculous that this malfunctioning product is the only way to attach a high-res screen to the macs.

    Works fine for me - beautiful display.

    I've been using this adapter to connect to my 30" Cinema Display with my Macbook Air (model 2,1) 1.86GHz ever since I got the MBA (December 2008). It works fine.

    The only problem is that there are too few USB ports (only 2) and anyway the MBA Superdrive can't use them! The firewire ports on the Cinema Display are redundant as the MBA has no firewire.

    Works exactly as advertised

    The adapter works exactly as advertised with my Gateway XHD3000. Unplugged mini DVI, plugged in mini Displayport and USB cables, plugged in Dual Link cable, and voila, glorious 2560x1600.

    I was worried that it wouldn't work because of the low-ish reviews, but I had no problems.
