    replaced adapter to solve flicker issues

    • Written by from Montreal

    I had all kinds of sporadic flicker and static issues with this adapter on a 2009 mac mini. Couldn't isolate the problem. Everything cleared up when the apple store replaced the adapter.

    Got it working, but no thanks to Apple

    • Written by from AMHERST

    Bought this to use my old Dell 3007WFP monitor with the new Retina Macbook Pro. On initial hookup the display was only detected in 1280x800 mode. The full 2560x1600 resolution was not available as an option. A call to Apple support was less than helpful with the end result of the support person giving up because it wasn't Apple monitor. She was also unwilling to escalate the call, or to put in a request for an engineer to look into it. A terrible experience, and it really tarnishes Apple's reputation in my mind.

    I was able to confirm the adapter works by testing on the old MacPro, so I was pretty sure it wasn't actually a hardware issue. Many hours later I did find a solution to let the laptop use the full resolution. It involved using the SwitchResX app, which you can find using google. It's still not a perfect solution since it costs a few bucks, and the solution doesn't use the Macs built in UI. But it does save me a grand for a replacement monitor. As a side result SwitchResX lets you use the full resolution of the Macbook Retina display. So now you can have a bigger desktop than the 30" display crammed into a 15" display. Get out your reading glasses.

    I am hopeful Apple will fix this with a patch to Lion, but given that the support staff refused to bring it to the attention of the developers I probably shouldn't be.

    Flicker = Power Issue

    • Written by from SEATTLE

    Great intentions for this apparently quick fix solution. Yeah, for what is rare to happen, Apple botched a bit on this extension. I can't complain in the end though because at least it works as desired.

    USB on almost every class of machine have the tendency to have power related issues. Devices that have a separate power adapter don't have to rely on this voltage. Bus powered devices are all trying to pull the voltage they need. In this case v1.02. If for any reason you get power fluctuations, your monitor will flicker, have issues, or not work at all.

    The Fix, plug the USB cable that is on the Y with the Mini DisplayPort and plug it into an external powered USB Hub that has its own power adapter.

    Don't have a powered USB Hub? No problem. Try using the 2nd Monitor's built in USB Hub. Plug the USB from the Y and plug it into your iMac and then take the USB out from the Mini DisplayPort to Dual-Link DVI Adapter and using a iPod/iPhone power cable and plug it into a Wall outlet for AC.

    Not sure any other way of doing it is worth it. Still glad I got it because there isn't really a better solution out there at this time.

    New cable with Firmware 1.03 did the job!!!

    • Written by from Edgewood

    Followed the advice of entry: Aug, 2011 from MK Atlanta. I "Screen grabbed" (Cmd + Shift + 4) and printed MK's entry, and information about my Mac's hardware, which showed that I had a old 1.02 firmware cable. Took all the printed information and old cable to Apple store and they exchanged it, no problem. We weren't able to test it as the store was packed and everyone was using the monitors and laptops etc. But as soon as I got home, connected the new cable no problems, no snow, no flickering....Halleluiah!!! Why can't they post this, or send us an update? My new Subaru has had some computer updates since I bought it in February..... I get a letter, take it in, update, end of story. (note: I have a mid 2010 MacBook Pro)

    Sync fix

    • Written by from Coral Springs

    I experienced the out of sync issues about 3-4x a day. What I've found works every time is going in to display preferences and changing the resolution down to 1280x800 and then back to 2560x1600. It seems to reinitialize the screen that way and fix it. Since that works it is probably a software issue and should be corrected in a software update. I'm hooked up with an aluminum Macbook to a Dell 3007wfp-hc.

    Works for me, but has some display issues

    • Written by from Mission Viejo

    I was also scared off by the reviews, but since this was really the only option available to connect my 24" iMac to my 30" Cinema Display (which I already owned and previously used with a PowerMac G5), I decided to bite the bullet and order it.

    Luckily, it works, and for the most part, works well. The image quality is very good and I love having two big high quality monitors for apps like Aperture, Photoshop and Final Cut Express.

    However, I'm a tad disappointed that there are flickering horizontal pixels lines visible in the dark areas. The lines are usually red, but occasionally other colors and seem to appear toward the bottom of the screen most frequently. If I set the background to pure black, they are more visible throughout, but under normal use, it's not noticeable enough for me to return it...especially since I have no other option.

    If I can find a way to fix this, I'd give it 4 or 5 stars, but as is, it's just an average 3 for me.

    Works fine except when waking up

    • Written by from Newton

    Works just fine with my MacBook Pro much of the time, but has periods when it flakes out: sometimes after waking up from sleep I get a bunch of static on my display (NEC PA271W). Power cycling the monitor clears things up, but it is annoying. Fortunately my monitor also has a DisplayPort input so I've switched to using a mini to regular DisplayPort adapter (also much smaller, cheaper, and doesn't need a USB port). If you've got no other option besides dual-link DVI then this adapter works OK, but I'd go with other options first if you can.

    Connected to my Dell 30" U3011

    • Written by from SAINT LOUIS

    I reluctantly purchased the Dual-Link DVI to MDP adapter after reading the horrible reviews on this site and elsewhere. Yes, $100 to get full resolution seems excessive.

    I was able to get my 30" Dell hooked up and working properly. It works about 90% of the time, as I have multiple computers connected to the monitor, and sometime 1/10, when I switch the source input to my MBP, I see snow on top of my Mac OS screen. This is usually fixed by changing the input source to a different PC, then switching back to the MBP, or unplugging/replugging the MDP.

    For $100 it should work 100% of the time. 3.5 stars in my book.

    If you don't need USB pass through, you can pick up a cheap MDP to DP adapter from Monoprice

    Hybrid rating: Replacing adapter fixed problem

    • Written by from Louisburg

    Rating is 5 stars for eventual performance, 1 star for putting many defective adapters on the market and making me (and many others posting comments here) deal with this. Average rating then = 3 stars.

    I have one of the original Apple 30" Cinema Displays which has worked flawlessly for over 5 years with multiple Macs. It has the original full size DVI connector on the end of the cable. When I recently upgraded from a 2006 MBPro to a 2010 MBPro I had to buy the dual link DVI mini displayport adapter to drive the 30" to full 2560x1600 resolution. The first adapter created the horizontal video lines on the 30". They would appear only in areas displaying dark colors. Apple Support (phone call) had me unplug EVERYTHING except for the monitor. They had me reset the PRAM (power-command-option-P-R for 2 sec) and then reset the SMC (shift-control-option-power) to no avail. So we made a Genius Bar appt and I took the adapter and my new MBPro back to the local Apple Store. We plugged my MBP and this adapter into one of their new 30" Cinema Display HD monitors in the store. Of course, everything worked perfectly.

    After some head scratching and no satisfactory explanation, they swapped out the adapter for a new one and sent me home to try out. If it still didn't work I was prepared to go back with adapter, MBPro, and my 30" monitor. Luckily, It worked fine when I hooked up everything at home. So take your adapter back if you see these horizontal video lines appear. It solved my video noise problem, it may solve yours.

    Got it. Now how do I connect it to my Dell?

    • Written by from Palo Alto

    The adapter arrived after the 2-month wait. The combo dvi-usb head does not fit into my Dell 30" 2008WFP monitor, and it will not fit into any non-Apple monitor. It will take me an additional two extension cables (short usb/short dual-dvi) to get it to work.

    That DVI/usb combo head crosses the line separating neat from annoying. Minor convenience of not having to plug in a usb cable when you dock, causes major incompatibility with all non-Apple monitors.

    An additional insult for the owners of DisplayPort capable Dell 2008WFP display, is that mini-DisplayPort -> DisplayPort cable is not available anywhere.

    Can't play rented iTunes content, and shows "snow" on blacks

    • Written by from Hamilton

    This adapter lets me connect my mid-2011 (Thunderbolt) MacBook Air to my old 30" Apple Cinema Display. It works for the most part, but it has significant flaws:

    1. Pure black areas show a little "snow" on the Cinema Display.

    2. The adapter doesn't seem to support HDCP, which means I can't rent a movie in iTunes and play it back on the 30" display. This is annoying given that I'm using an all-Apple setup, and renting iTunes content! (This does not seem to affect purchased iTunes video content, though -- just rented video content.)

    Neither is a deal-breaker, but both are annoying.

    Firmware Version 1.03 does not eliminate "flickering snow" problem

    • Written by from Cedar City

    I tried this adapter with a NEC PA271W monitor. I am using a 17" MacBook Pro (2011 model, 8GB RAM) with OSX 10.6.8. Initially, I was experiencing the "flickering snow" problem about 25% of the time when my computer woke from a sleeping state.

    It was very frustrating to have to cycle the monitor off and back on or to unplug it from the computer and then reconnect it so often to clear up the display.

    It was able to reduce the frequency of the problem by connecting a USB cable between the monitor's Upstream USB Port 1 and the USB port on the Adapter. But this did not eliminate the problem.

    NEC tech support sent me a Mini DisplayPort-to-DisplayPort cable (NEC Part Number PA-MDP-CABL, price $29.99). They also instructed me to connect an A/B USB cable between the monitor's Upstream USB Port 1 and the computer.

    So far, this has fixed the problem.

    This cable does support the Monitor's highest resolution, 2560 x 1440, 60 Hz.

    I do not know how well this particular cable will work for non-NEC monitors. There is a latch on the end of the cable that locks into the DisplayPort on my NEC monitor. I do not know if the DisplayPort connections on monitors from other manufacturers have the same fitting.

    Works fine but so pricey

    • Written by from Binningen

    Seems to work without any issues so far described by others. I am just very surprised that my adapter has firmware 1.01 even though this seems very old and supposed to not work. Hence only three stars as it is very expensive and with outdated firmware.

    Flicker

    • Written by from Walnut Creek

    New 17" Macbook Pro and 4 year old 30" Cinema Display. I have my display set to "Higher performance" in the Energy Saver preference pane.

    When displaying large areas of black on the Cinema Display there is clearly flickering horizontal lines. I once tried unplugging and replugging in the connector and the flickering was a bit less. But I do plug the adapter in virtually every day since I commute with the laptop. Generally speaking it will flicker when displaying black areas.

    I will probably try to return it for another one to see if it varies.

    I can live with it if there is no fix as the flicker is only there in black areas.

    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

    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!

    Buy this adapter or they'll kill your dog

    • Written by from Mississauga

    I initially purchased the single channel adapter not being aware of the 1280x800 signal limitation. I returned to the store (without packaging, but with receipt) and explained that it was unlikely anyone on the planet would benefit from the single channel adapter, and the staff agreed. I was given full credit for the single channel and purchased the dual.

    It worked as expected, and I am running 2560x1600 w/millions of colours. No flicker, no warbles. Samsung 30 inch SyncMaster 305T.

    So why a 3 star rating? Because it is a solution after the fact. My old MBP had a DVI port on the side and ran this monitor just fine. Exactly how is this Mini DisplayPort suppose to benefit me? There is a high PIA factor plugging two cables where prior I had one and now I have 3 feet of cable and a box the size of a deck of cards on my desk.

    So in summary.. If you are reading this, chances are that you already purchased a new laptop and are trying to solve your display problems. Go ahead and buy it.

    Like others I have to unplug and reconnect a few times to get the screen to come on, but once it does I enjoy the 30" cinema display in all its 2560x1600 glory. Now if they could just get it working on the first time you connect it that would be great.
