    Terrible - defective junk

    • Written by from Chicago

    Bought it for my uMB, tested it and it left all sort of distortion lines everywhere. Slightly better if you plug the USB into an external USB power adapter but that lasts 10 mins. There needs to be a recall on this. I returned it the same day.

    Have they recalled this yet?

    Flickers the monitor to the point of uselessness.
    Worked great for 5 minutes. Since then it is worthless.
    Almost as if something burned out inside once it was plugged in to a 30" monitor. Seriously, Apple, overheating batteries, cracking logicboards, and now this!

    Flicker

    • Written by from Vadnais Heights

    I purchased the 2.8GHz MacBook Pro. I have a 30" Cinema Display at the office and the new 24" LED Cinema Display at home. I was disappointed that I had to order a $99 cable for the 30" display. Initially worked fine but develops an annoying flicker in the background. Usually not seen in an active window. This is an annoyance and significant disappointment considering the upfront costs.

    Agreed: worst Apple product ever.

    • Written by from Tucson

    I really hope this is a software problem with the NVidia chip and not a problem with this adapter... but the flickering is ridiculous! They say it's not compatible with non-Apple monitors and say that's the reason for many users' problems (complete nonsense...) but that doesn't explain the identical problems I have with my NEW Apple 30" that worked perfectly with my old MBP 17".

    There had better be a fix soon because this is ridiculous.

    Mac Mini(2009) Problems w/Adapter

    • Written by from Fremont

    Just to chime in with the rest of the crowd, I'm also experiencing flickering issues with this adapter. I have a new Mac Mini w/Nvidia graphics that powers the 30" Cinema perfectly, no graininess or distortion, except for that irritating screen flickering every 15-40 minutes. I thought the Mini had issues, I'd never suspect it was the adapter until coming to this forum. Hope Apple fixes this problem soon considering that the adapter was 1/6th the price of the Mini.

    Works Great! People with 1-star reviews were using incorrectly.

    • Written by from Palo Alto

    I'm using this adapter right now from my 15" mid-2012 rMBP to a QNIX QX2710 LED EvolutionⅡ2 27" 2560x1440 PLS Monitor, which states on the seller page on ebay that it is "not compatible with laptops and mac computers," and that "Internal GPU, APU, and low-profile GPU are not compatible." The rMBP uses a GT 650m low-profile GPU. It later states not to use a port converter (eg mini dp -> dual-link dvi), this warning does not account for active adapters like this one, which uses a usb plug to provide additional power. If cabling permits, plug the usb port INTO AN OUTLET to ensure that it's receiving sufficient power. In any case, don't plug it into your laptop, run it off battery power in integrated graphics mode and write a one-star review when it doesn't work.

    it does flicker occasionally but it works

    • Written by from East Lansing

    I have two Dell 30's running on one video card, and they do flicker occasionally. It's annoying, usually requires a reboot, and I don't know why. I opened a support case at Apple just in case it got worse, but so far it's pretty rare, and when it's working the resolution is magnificent - 2500x1900, very sharp and quick.

    Fine so far

    • Written by from CHICAGO

    Despite reviews to the contrary, the Dual-Link Adapter is performing almost perfectly after 3 days. Video performance has been flawless with my 30" HD Cinema Display hooked to my new Mac Mini (replacing my aging Mac Pro). The only hiccup that I've noticed thus far is that audio has twice dropped from my USB speakers that are plugged into my display USB port (defaulting the the Mini's speaker). So there has been the minor annoyance of re-selecting my speakers in the Sound Preference. It's not yet clear if this will be a daily event or is triggered by a specific operation.

    BTW, if you have the the 30"HD display, don't even consider the HMDI adapter as a viable alternative. It's functional, but the poor resolution will hurt your head.

    works fine but too expensive

    • Written by from Stanford

    Despite the endless series of negative reviews, I bought this to connect a Samsung 305T to my MacBook Pro 15" Early 2011, and it seems to be working just fine at 2560x1600 (not mirroring) for now. It is too expensive so I really can't give 5-stars.

    Hope my words could help hesitant people make their decision to buy this adapter for non-Apple displays.

    Expensive and Bulky

    • Written by from Saint Paul

    For the price, this adapter should include a dual-link DVI cable. The adapter doesn't work properly unless you have the very latest version of the cable (with 1.03 firmware), so don't look for used cables on eBay. The adapter is bulky and requires the use of a USB port (though it does have a USB port on it). If you have a MacBook Air, and especially if you want to use an Air SuperDrive, you will have trouble connecting everything at once. This is because the SuperDrive will not work with USB hubs.

    Sadly, this is the only option available for some people depending on their display. If possible, a Mini DisplayPort or DisplayPort connection (with adapter) is a better bet for hi-res work.

    Unacceptable and Apple Support is Unable to Provide Solution

    • Written by from homeland

    I purchased a Makpro with two graphics cards supporting a total of six monitors and four of these adapters for a trading application. Every now and then a monitor will go blank at random and when that happens all the monitors fail to blue screens and when they reinitialize, the contents of all screens are scrambled. Support has asked a lot of questions but has not provided any solutions and now is not responding to my emails. I will have to return the computer and adapters and go back to the dreaded PC's (which have other issues but not this one). Too bad, otherwise, the computer is quite good. I have 8 Macs total so I am not new to them.

    Works well with 17" Macbook

    • Written by from Westmount

    This adapter works fine with my 17" Macbook Pro. Note that the adapter draws power over the USB connector, so that must be plugged in even if this is used with a non-dual-link display.

    Flickering Horizontal Lines

    • Written by from La Habra

    Computer is a new i7 iMac, secondary display is a 30" Cinema Display. In black areas of the screen, there are horizonal lines flickering across the screen. It's usable, but ugly.

    Apple won't send a replacement until they receive this defective one, which will leave me out of commission for a week or two. I stopped by an Authorized Apple Retailer, and got another DisplayPort adapter. The replacement was WORSE than the original.

    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.

    Lines in dark areas of screen on Apple 30" Cinema!

    • Written by from Kaneohe

    I too have the adapter (V1.02) hooked between to my NEW Mac Mini and my 3 year old 30" Apple Cinema display and I am experiencing the same problems with the horizontal video static lines. Unacceptable when watching a video! I have reset everything per all the tech suggestions to no avail. I have searched for the new firmware V1.03 but have not found it anywhere on Apples site. Please post the firmware revision 1.03 Apple Tech Guys! If someone knows where to download the firmware update please post!

    this cable work on my NEC 30" 3090

    • Written by from Sydney

    just bought this cable plugin from my new mac mini to NEC 30" multsync 3090 monitor. It works so far without any problem.
    No flick
    No noise
    No problem after sleep.
    The 2460x1600 res is very detail and line is very sharp and fine showing on my monitor.
    Before I bought this cable, I had tried this cable with a apple cinema 30" in an apple store also no problem.
    I think it does the job..

    I don't like just it is too expensive but 30 " with 2460 res need this so I have no choice and I don't even know what else cheaper can replace this.

    Also not many staff in apple store I have been know this cable well.
    I heard someone can't get this cable work is because the firmware of this cable is not 1.03. Also no one in apple store can confirm to me the one I bought is 1.03 or not.

    Luck I have my one work and I think my one is the latest firmware

    1.01, 1.02 all bad. Went through 5 of them all cause distortion eventually.

    • Written by from Mundelein

    All failed eventually even with external USB charger (Apple as well). They work for a while, then after 2-3 days it starts with flicker, then garbled screen out of sleep, then screen goes garbled even in the middle of the work. Feels like something burns out in these adapters. I have not tried 1.03, was not sure they even did 1.03 but doubtful that it will solve it. Seems hardware related.

    works for me.

    • Written by from san bernardino

    I just received this adapter a few days ago and tested it out with my new apple 30" cinema display & slightly older 30" gateway xhd3000. Both Monitors hooked up with this adapter seem to work perfectly with my 15" unibody MacBookPro 2.53 w/ nvidia geforce 9600m GT running 10.5.7.

    I ran the screens for around 5 hours, did some photoshop work, watched some hd videos and I didn't encounter any of the distortion problems that i've seen in the forums. I checked the adapter firmware in system profiler , & it says 1.02.
    I was expecting something to go wrong, but so far so good, atleast for me.

    The only things i don't like are the price, the wires with huge white boxes..Oh and it needs to be plugged into a usb port to run. Mines plugged into the lower usb port next to the mini display port.

    anyhow hope it keeps on working. I'll be back if it doesn't.

    A bit on the inferior side

    • Written by from Madison

    I have 2 setups with unibody MacBook Pro and 30" Apple monitor. I'm on the phone with Apple right now switching out the cable for the 2nd time. Works fine for a couple of months and then, launch up to a non-working monitor. By process of elimination, we've deduced it is the cable that is faulty. Going on my 3rd cable now. Kinda blows!

    Ditto for me - Brand new 13" MBP with a brand new Dell 30 monitor

    • Written by from Nepean

    I get the random fuzziness - thing is I have typically 20 or more windows open and they scrunch up into the 13" inch screen each and every time I "fix" the monitor. Not exactly the productivity solution I was looking for I'm afraid.

    Adjusting the resolution seems to help if you go to a really low setting (1280 x 800 or lower) however I still have to unscrunch all my previously nicely arranged windows...

    Identical problem occurs on a Samsung 27" monitor as well so I know it is in Apple's domain.

    Apple: Fix This!!!!
