Reviews for Mini DisplayPort to Dual-Link DVI Adapter

Setup: Mac Pro 2010 with ATI Radeon 5870 with two duallink DVI to minidisplayport adapters and three DELL 1920*1080 LCD monitors.

After sleep the computer frequently hangs for a while and then responds again. Time for another firmware update?

I read the negative reviews of the adapter... but having a 30 inch cinema display I need to use with my Retina MacBook Pro, there weren't a lot of options.

Worked fine until... yesterday when I came back to my desk and my system had shut down due to a kernel panic. Joy, upon reboot discovered that all my email accounts were wiped out. 3 hours later after restoring MacOS and all my data from backups i discovered it was the DVI Adapter that failed and caused the panic. Wow.

Starts off ok, but over time this becomes almost unusable. I've used the Mini DisplayPort to Dual-Link DVI Adapter for just over a year with a 2011 MacBook Pro with Thunderbolt port and Dell 30" monitor. For the first few months I didn't have any problems, or none that couldn't be fixed by simply toggling the monitor off/on. But over the last few months the problem has increased in frequency and severity. Often the only way to get my monitor back is to shut down my system for an hour. If I'm lucky I may get a few hours of work afterwards. If not the snow/distorted pixels, flashing, blinking, and gray/black screen will reappear a few minutes after starting up.

I did not have any problems (and still don't ) using this monitor with a 2007 MacBook Pro with built in Dual-Link port.

Sorry, it there are typos in this post. My monitor is blinking on and off and pixels are distorted with snow, so I can't proofread what I've typed.

Makes my macbook pro freeze up randomly... very annoying and expensive.

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.

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.

I have used this with both a Dell 2407WFP-HC and a Benq Q24W5. Roughly 33% of the time, upon waking the MBP from sleep the external screen is covered with coloured noise. Even worse, once in a while (maybe 1 out of 10 times), while unplugging and plugging the adapter back in the entire system locks up with the blue "I'm examining the displays" screen. Only get the Dual-Link adapter if you *really* need it. Get a single-link (or HDMI or regular display port) adapter if at all possible.

This adapter works fine, I have a 30" Cinema Display running. I think most of the negative comments result from the earlier model which has an outdated bios version. If you do purchase from other source, make sure it is the latest model production. Wish adapter supported firewire is my only criticism.

After reading the bad press on the adapter I wanted to be 100% sure that my 30" display was going to work with the new MBP, so I boxed it up and took it to our local Apple store. The sales people were more than willing to provide this adapter to connect it to the new MBP. They only had the Retina display models, but since the Retina and the anti-glare models (which is the one I wanted to buy) use the same video card and I figured if it works with one it will work with the other and IT DID. As soon as I saw it worked I placed the order.

I just received my new MBP 2.7GHz I7, 8 GB ram, 512 SDD with the 15" antiglare screen and connected to my 30" cinema display this adapter and I have full 2560x1600 resolution. In fact, I would say the overall quality being displayed on the 30" is actually better than it was using my 2008 MacBook Pro that I just replaced.

I decided to buy this adapter due to the fact that they updated its firmware to 1.03. Turns out it didn't fix anything. It still gives a static/snow distortion to the external display when waking up your computer from sleep mode.
