Reviews for Mini DisplayPort to Dual-Link DVI Adapter

I had concerns about buying this because of all the bad reviews but went ahead anyway because I would have had to buy a new monitor. It worked perfectly for connecting a mac mini to a 30 inch Apple Cinema display with full 2560 x 1600 resolution. I found it awesome!

Using mid-2011 13 inch MacBook Air to drive a 30 inch Dell display. 3007WFPHC at 2600 x 1600. After reading the comments, I connected the USB plug to my iPad charger, so that it can draw as much power as it might need. I am not sure if connecting to the macbook air usb will also work.

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.

Even with the latest version 1.0.3 firmware this adapter is terrible. I've had issues using it with multiple monitors from my 2011 Macbook Pro 13" i7 2.7Ghz. Flicker, snow, image jumping. Apple support told me that I have to power my monitor off and back on for things to work properly after the monitor had gone off with energy saver settings. This works sometimes, but even after power cycling the monitor after a while the problems come back.

It's massively overpriced and doesn't work as advertised. Apple should really resolve this or pull it from the market and stop advertising that their portables are able to drive a 30" monitor, because with this being the only solution they offer to do so .. it's just not usable in a professional capacity.

I use this with a MacBook Pro 15" and a Dell U3011 monitor. It works great and I haven't had any problems.

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)

I've had this adapter for a few months now. As a long time Apple fan, this product is very dissapointing. I use this adapter on a mid 2009 MacBook Pro connected to a 30" ACD and it flickers like crazy on dark blacks. I primarily use the ACD for editing in Aperture... So I experience the flickering issue a LOT! I really expect better from an Apple product, especially when its a $100 cable connected to a $2000 display. I plan on trying several of the things I read on this forum tonight (such as using an iPad 10w adapter and checking the firmware), but even if they work this is a still a fail. Apple products should not need "fixes" they should just work.

I recently bought a 15" Macbook Pro Intel Core i7 and needed this adapter to connect my 30" Apple display. I connected them together, and it worked flawlessly, just like it used to work with my old 17" Macbook Pro Intel Core 2 duo (which didn't need the adapter). No complaints!

It's a little pricey, but it works as advertised. My MBP (2010) drives my 30" Cinema Display without any problems. I haven't experienced the flickering some have talked about. The cable seems kind of bulky, but its length is outstanding. Any shorter and it would pose a major inconvenience in trying to connect. (The Display's actual DVI port is very close to its brick, you see.)

The adapter works fine with Samsung SA850 27" monitor achieving a screen resolution of 2,560x1,440. Make sure the firmware of the adapter is version 1.03.
