    Frequent screen issues

    • Written by from Vancouver

    I finally received my adapter last week. I use a 30' monitor at work and wouldn't live without it, so my new MacBook Pro has been in a drawer until yesterday (purchased the computer in October). I have purchased all 3 adapters for various purposes, but the Mini DisplayPort Dual DVI adapter is a great disappointment. On my Samsung 30', the screen flickers periodically or goes completely out of sync and this is incredibly annoying. I have tried a number of solutions as suggested in various on-line forums all to no avail. The only way to temporarily resolve the problem is to disconnect the adapter cable. If you regularly use a 30' monitor then I would delay purchasing a new MAC notebook computer until this problem is rectified.

    Flickers and shuts off

    • Written by from Anchorage

    I've got one of the brand new unibody MacBook Pros and also just purchased a 30" Cinema display, seemed like a great idea to me. Then I realized that I needed the $99 adapter, ok, well drat, whatever as long as it works. Got my adapter in the mail two days ago. So far I don't have all the artifacts that people are talking about, but if I shut the lid on my MBP I can't get it to wake up for more than about 3 sec at a time then it flickers and goes back into sleep mode. The only way so far I've found is to restart my machine (in those 3 sec its awake, gotta be fast) then it'll work ok for a while. I haven't used it long enough to see the artifacts or lines yet.

    They must have known

    • Written by from SAN FRANCISCO

    This thing only works part of the time. When its good its good, but it goes bad many times a day requiring either sleep display, disconnect cable, restart etc.. to get it to work again. Snow, garbled screen whatever you want to call it.. How could this have possibly gotten through QA?

    I am very disappointed. $99 and two months of waiting later, I got a product that doesn't work to spec. My Samsung 30" display (which conforms to ALL the specifications Apple laid out on its product literature for the MacBook) goes out of sync every few minutes. Unplugging it and plugging it back in gives me a few more minutes. This is not a useful product for me. Considering that I purchased the MacBook for the sole reason that it featured Dual Link DVI output, I am feeling swindled.

    Extremely Disappointed

    • Written by from Merritt Island

    Just bought a new MBP and also a 30" Gateway Monitor to use with it. Right after I bought the MBP, I purchased this adapter and apple said it would ship in 5-7 days. After waiting a few weeks I checked online and then found out I'd have to wait 2 months to receive. It gets better. Now after I finally received the adapter, it simply won't work with the Gateway 30" monitor, the monitor is only seeing it as a plain DVI and I can only get 1900X1200 res. SO frustrated. If anyone has a solution please post.

    Frequent problems

    • Written by from Brattleboro

    Several times per day, my display that is plugged in to this adaptor will suddenly become unusable due to varying patterns of interference showing on the screen. The only way to fix it is to unplug the adaptor and plug it in again.

    As there is no other way to plug in a 30" display to a unibody MacBook Pro, and there is no 30" display currently available with a native Mini DisplayPort interface, I have to suffer through this. I wish I had kept my old MacBook Pro, as it's DVI interface was able to drive my display without problems. I advise anyone considering upgrading to a recent MacBook Pro to NOT do so until Apple has fixed this problem.

    Poor performance

    • Written by from Ferndale

    The adapter works, but not anywhere near satisfactorily. "glitches" in the display are seen all the time, especially in black patches of the screen.

    Sometimes after going to sleep, the monitor will ghost the display three different times.

    You have to unplug and plug the monitor back in several times a day.

    My 30" cinema display is sad and my workflow is interrupted constantly.

    Shame on you Apple. Do you care about us? Or just those people buying your new LED displays?

    Arrived today. With my Dell 3008WFP it only supports the 640x480 resolution. Took it to the Apple store where it was plugged into a Apple 30'' Cinema display. With the Apple display it supports all resolutions up to 2560x1600. Whether this is sloppy engineering or Apple protectionism remains speculation.

    dual link dvi cable not recognized by Gateway

    • Written by from Herndon

    Bought a brand new aluminum macbook because it supported 30" displays. Checked at the Apple store to make sure my Gateway 30" was supported - no problem. After buying the computer, I was told that it would be a couple months to wait for the dual link dvi adapter. The worst part was still coming. It arrived the day after Christmas - the gateway doesn't know it exists - thinks its a regular DVI. So I'm stuck with a new macbook that can't accomplish the tasks for which it was purchased, a high res monitor that thinks it's low res, and a $99 cable that doesn't work. So much for my first experience with Apple...

    Stupid adapter blows buttt

    • Written by from joliet

    I had the flicker too, I had my resolution set to the highest setting because I forked out the extra $ and bought the 2.8 ghz and maxed ram. But I had to lower my resolution to make it not flicker. And it blows because it is not as crisp as the highest setting but it is a fix for now till I decide to get on the phone with apple (UGH!). So hope this helps.

    Jitters on the letters

    • Written by from 京都市上京区

    This is a new product. I am not surprised that the bugs are not worked out. But I am disappointed that it does not work properly. I had no problems with my one year old macbook pro and the old dual link with my Dell 30 inch monitor. So why change what works? But apple did and I have the newest macbook pro. I waited a month to get this adaptor. And from the get go this product performs poorly. What happens is the letters all over your screen, from the top menus to the words in your screen seem to jitter or double up on top of each other. Letters become unreadable. And there is no predicting this. The first time I hooked up it went badly. I restarted and it worked. Now it seems to happen randomly. It does not matter which setting I use for the graphics card in the energy saver. Both go badly.
    A restart seems to fix it for a while. But at some point the problems rear their ugly head and you cannot read anything on your computer screen. You restart and hope you did not loose your train of thought at work.
    Do not buy this if you expect it to perform as it should. It does not. Use your older machine with a dual link port for performance and wait for Apple to make it right.

    Ridiculous product...

    • Written by from Bend

    I'm using this cable with a Samsung 30" monitor, and 2-3x per day, the monitor loses sync; this never happened with my older MBP and the same monitor (using dual-DVI). The cable is WAY too expensive and just doesn't work properly. Apple should be ashamed. Does anyone know how I can get this remedied?

    Colored Streaks Constantly Flicker Across Screen

    • Written by from Mountain View

    Especially noticeable on a dark background, streaks of random colors flicker across my 30" cinema display.

    This adapter costs waaay too much and I waited an extra month for this to ship. I sincerely hope that Apple does the right thing and has a recall.

    Very dissapointed!!!! :(

    • Written by from Cherry Hill

    Just hooked it up to a Dell 3007WFP display. It flickers often and then the monitor also goes all blurry and you have to unplug the adapter and plug it back in to get it to work again. This occurs every few minutes. I am using the Belkin high bandwith DVI cable which was also $100.00. I hope this was just a bad batch!!

    Flickers, jumps and other irritating analog type defects. This is $99 that also can't keep the monitor from randomly shutting off. This should be recalled.

    I just received this adapter and it works for about 5 seconds before my Dell 30" display goes out of sync. I returned it to the apple store, but they don't have any in stock to replace it, so they gave me a refund (minus the shipping cost). Now I'll have to try again -- maybe it was just defective.

    Flicker, sporadic issues...

    • Written by from BOSTON

    Major issues...

    First, when I plugged it into my brand new 2008 Macbook Pro I got a message saying that the USB device drew too much power! I did manage to make it work by plugging it into my monitor's USB hub, but wow...

    Secondly, there is a slight flicker. You can see it clearly with certain kinds of backgrounds and fill patterns. It almost looks like the kind of noise you get with analog, except it's DVI. It's not a severe problem, but *any* flicker with DVI is ridiculous.

    Finally, sometimes it just fails. The screen will go all weird, and you have to reset it. Again, it looks like an analog failure mode except it's not...

    I'm going to wait a bit and then trying exchanging my adaptor at the Apple store. Maybe there are issues with the first-run units.

    Apple really botched this one. Dongles are bad enough, but overpriced broken ones... come on guys...

    Incompatibility Issues

    • Written by from Leonardtown

    I think the theory of this product is sound and I really hope Apple releases either some support documentation or graphics driver updates to help it perform better. My experience is that when connected to a 30" HP LP3065 2560x1600 monitor I can only get the macbook to put anything on the monitor when it is "mirrored" off the laptop screen and even then only at 1280x800. With my other Panasonic Pro TH-50PFD9UK 1920x1080p compatible plasma display I was able to get it to output video in what appeared to be 1920x1080, but again I believe this was only in "mirrored" mode. Personally, I think it is some sort of obnoxious joke that Apple shipped this product with no documentation and no tech support website.... sure, the Apple user experience is just so magically awesome that it will just telepathically "know" what I want it to do when I plug it in... either that or I am supposed to be magically aware of all of the configurations and software settings it needs as soon as the breathe the air from the open box. Just ridiculous! But I have high hopes.. so please get us a software driver update that robustly supports this product, it has huge potential!
