    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.

    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!

    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.

    So Far So Good

    • Written by from Orlando

    Despite months of negative reviews I bought this yesterday for my 2.53Ghz Unibody Macbook Pro. When I first got it home I was seeing all kinds of problems running it at 2560 x 1600 on my Dell 3008wfp. The image was shifted making text blocky and unreadable. Just when I was about to go return the adapter, I tried the cable that came with my monitor. Since then I've had no issues running at full res for about 24 hours in and out of sleep both with integrated video and dedicated. I'm using a USB port on my MBP with no special configuration. If you're having issues, try swapping out your DVI cable with a high quality, short length dual-link DVI cable.

    I'm suprised and happy that it's working great, but still mad at myself for investing in a laptop that requires a $100 adapter to use with my monitor.

    So far, OK

    • Written by from MONTREAL

    I got the adapter in February, but didn't receive my 17"MBP ordered at the same time until April, so didn't have a chance to try the adapter until this last weekend and week. When first connecting to my NEC 3090, the screen became fuzzy and unreadable. I unplugged the MiniDP port connector and reconnected, and it was fine. No problems since. The screen was earlier connected to my 2008 MBP with dual link DVI output.

    I'm using the MBP's USB port for power; it's clear the adapter needs it, since it gets quite warm during use. I have no downstream USB port(s) connected to the adapter. The other MBP USB ports have been connected at the same time, so the MBP seems to provide adequate power for three components. To be on the safe side, I've made sure that the adapter hangs free to maximize air flow for cooling.

    The adapter does not allow calibration software on the computer to connect to the screen; this is a known problem. To calibrate the screen, I have to use the old MBP. If I have problems later, I'll post. I've given the adapter a 3 rating because I think it's ridiculous to abandon the usual DVI connector and require customers to pay as much as Apple demands - not to mention the cost of a USB hub, where some have required it.

    Initial problems now solved with Dell UltraSharp 3007WFP-HC

    • Written by from SAN RAFAEL

    I had the same problem as anyone else with flickering and bad noise intermittently. It got so bad at some point that every switch back and forth with my Dual DVI KVM switch screwed up my display.

    What finally solved my problems was to connect the usb cable directly to the usb hub in my Dell UltraSharp 3007WFP-HC monitor. As another review states here the problems seem to have to do with the quality of the power that the usb cable receives. Apparently my monitor does a good job with that.

    A fix for some problem cables

    • Written by from Monrovia

    I was able to get good performance from this adapter by powering it from a high quality external USB power supply.

    My adapter will lose sync several times a day when powered from my MBP's USB port. The CDR in my adapter loses phase lock during laptop power transients, such as during HD spin up. I tried various USB power sources and found a Belkin powered USB hub that fixed the problem. My adapter has not glitched when plugged into the powered hub.

    I believe the powered hub provides cleaner USB power than the laptop does.

    This trick will probably work for some people and not for others. Due to manufacturing variation individual hubs and adapters differ slightly. The current adapter design seems to be marginal so that these small variations can have a functional impact. So caveat emptor and YMMV.

    Works after attention so far...

    • Written by from Frederiksberg C

    I bought this Dual-Link DVI Adapter for my Triplehead2go.. Max resolution before was 2400x600px.. Now i can get op to 3840x1200px!!
    But I would have prefered a DL-DVI plug at the side, like the previous macbook pro.. And savede 99$ and all these adapters.

    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.

    Got a Fix to the Flickering Issue for MacBook Pro

    • Written by from Boulder

    Had the same problem that everyone else seems to have, but got a fix from the apple store:

    For the MacBook Pro (15", unibody)

    1) Open System Preferences
    2) Open Energy Saver
    3) Check the button for Higher Performance.

    The issue disappeared and everything is working fine now.

    Mostly works

    • Written by from Champaign

    I was glad that it has a USB pass-through because I really didn't know how I was going to handle even one less USB port on the laptop. Still I need a hub because the 30" Applemonitor only has 2 ports.

    As for the quality of the device, it works most of the time. Every couple of hours it will blink a blank screen for a fraction of a second. I can deal with that.

    I really just want a 30" version that uses the display port natively and has more USB ports. But I'll have to wait and see if Apple makes one.

    Not perfect, but I'm having pretty good results

    • Written by from Bothell

    I have a 15" MBP unibody and a Dell 3007 WFP-HC 30" Monitor. I received the adapter two days ago. I have seen the fuzzy blur and have also experienced the brief flicker, but not to the extreme that others have.

    I'm finding that when I first turn on the MBP, that is when I (sometimes) get the fuzzy screen. If I disconnect then reconnect the USB cable from the adapter at the MBP it will re-sync with the monitor and the fuzziness disappears and stays gone. The flicker happens from time to time (maybe 2-3 time over an 8 hour day) and I don't know the cause or a solution, but aside from being frustated that it occurs at all, it hasn't been too annoying.

    I'm really hoping that a firmware update will come from Apple, as I suspect that it is not the hardware. I was encouraged that the MBP 17" also has the mini display port. I cannot imagine Apple's entire laptop line not being able to work properly with standard 30" monitors using DVI cables and also the current 30" Apple Cinema Display.

    I purchased the MBP in December and have been using just it's monitor. I have to admit that at this point I'm just so happy to be using my 30" display again!!!!

    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 so far

    • Written by from Berkeley

    I was nervous getting this for my MacBook Air based on the experience of others, but mine seems to be working well so far with a 30" Cinema Display.

    I had been wondering about the purpose of the USB connector on the adapter (I figured it could either 1) simply be used to pass the USB connection from the display to the computer, 2) be required to provide power to the adapter, or 3) somehow be required to control the adapter -- the requirement for OS X 10.5.6 seems odd for a display adapter). Based on my initial tests, it seems like the USB connector on the adapter is required to be attached to the laptop (perhaps indirectly via a secondary hub) in order for it to work (simply plugging the USB connector into a powered USB port is not sufficient), suggesting that the USB connector provides more than just power.

    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.
