Reviews for Mini DisplayPort to Dual-Link DVI Adapter

I have the same issue often reported here of flicker and noise coming through the adapter. For those who think it works, I suggest you test with a black background (or play a movie) as the high contrast makes the noise impossible to miss.

It maybe, as one reviewer suggests, that people complaining merely have a defective adapter and it should be returned. Well, I did that and it still doesn't fly. Given the number of complaints here, I think it is pretty clear that the adapter is faulty. I tried two Apple Cinema displays with a new mac book pro, and I get the noise. My old macbook pro works fine. I am a huge supporter of Apple, but this product needs to be replaced.

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.

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.

I can only get a small % of the dell 3007WFP resolution.

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.

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.

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.

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

As I write this review, I've had to unplug and replug the adapter 3 (count 'em, 3! times). I am using an HP LP3065 display. I have all the same issues as everyone else on this thread. Apple should fix this adapter and replace all the ones that we bought.

Interesting product. Using my 30"Cinema HD with the adapter I was getting "snow" in the dark areas of the screen.

I moved the Dual link adapter to my Wacom Cintiq 21" and it worked without a hitch. The adapter was harder to insert initially for the Cintiq but after attachment there were no problems.

I am using another adapter to connect to my Apple monitor but it only drives to the 1280x800 resolution. There is not another product that will allow me to get the high resolution on the 30" Cinema Display. I now have to decide if I should buy another $99 Dual-Link DVI and try it out or wait for a product to come out that will drive my monitor.
