    144Hz White spot display problem

    I have BenQ 2430T. I use Dual-Link DVI Adapter. when I change to 120Hz, the display is ok. but When I change to 144Hz, there are too many white spot on Display. How can I solve this problem. But when I change to 144hz in WIndow7(bootcamp), it's ok. not ok in osx.....

    Works flawlessly

    MBP 8.1 / OSX 10.9.3 / ACD 30" / 1.03 firmware [adapter].

    No issues, at all.
    This adapter can use significant power.
    I'm powering it with an Apple 10W USB charger as a dedicated USB power source.
    If you have problems or have other USB devices that can use significant power, a dedicated supply can make a difference.

    works as designed

    I'm pleasantly surprised how this adaptor resurrected my Apple 30 inch Cinema Display. I've tried the adaptor with the Display on these Macs: early 2011 MBPro 17 inch, mid 2012 rMBPro and a 2013 Mac Pro. No flicker, full resolution and no problems. The adaptor connected to the thunderbolt port on all three Macs. Of course the only draw back is on the Macs with one thunderbolt port that the port is 100% tied up with the monitor. I imagine a thunderbolt dock could be used and daisy chaining a device for expansion.

    No problem at all

    After reading the many bad reviews I decided to call apple and see what they have to say. I was told there was no reason this should not work with my new LG Ultrawide 29" Monitor. If it did not work I could return for a full refund with in 14 days. On that information I decided to give it a go..

    It works perfectly so far. I hope it stays this way!

    Works Perfectly

    I have used this adapter every day for four years with my MacBook Pro. It has never caused the slightest problem.

    Works perfectly: Mac Mini 2011: 27" Korean reject, and full 1440p

    If you're reading this review, chances are you've banged your head against the wall trying to figure out how to hook up a computer to a 1440p display. I read all the reviews here, and bought the darn thing anyway.

    It works on my 2011 Mac Mini like a charm.

    The only thing I had to do was restart my computer and it worked. The resolution is 2560 x 1440, and adjustable.

    I hooked my mini up to a 27" Korean Thunderbolt knock-off I bought on craigslist.

    Lastly, if you're confused about the length of the cable, and all the ports, just plug the mini-display port into your computer WITH THE USB PORT into your computer. This is required, as high resolution displays draw power from your computer. As to the USB port on the brick itself, that's anyone's guess.

    I originally rated this at 4 stars, but I added the fifth after doing some math. I paid $380 all-together for what is essentially a $999 Thunderbolt display. This thing is gorgeous.

    Hope this helps.

    Works Just Fine

    Purchased 2 of these for a 1st gen Mac Pro with an unsupported ATI Radeon HD 5870. Works flawlessly. Have the DVI port to HDMI on a 32" LCD TV. The 2 mini displayports adapters plug to vid card and then use DVI to HDMI cable to 2 27" hdmi monitors for 3 monitors total. No issues! Just not sure what the extra usb ports next to the dvi ports are for?

    Works Perfectly

    I am using this cable to connect a new Mac Pro (2013) to a NEC monitor. I have attached the associated USB cable to an Apple 12W USB charger and this arrangement allows full resolution of the monitor.

    Thanks to other reviewers, I got this to work beautifully.

    So here is the scoop (although some of my facts might be a bit off).

    The computer industry was going along fine with DVI outputs on computers, but they produced these wonderful 30" monitors with 2560 X 1600 resolution that the standard outputs wouldn't handle. So they developed the Dual Link DVI connectors and standard so the computers could support enough throughput to power these monsters.

    A bunch of them were sold by various companies. Mine is a Hewlett Packard LP3065c, but Apple sold one and a number of other companies sold them as well. I got mine in a package deal from Costco, others bought the monitors for graphics manipulation or photography applications or what not.

    Then the standard became HDMI, which, although a step up from standard DVI output, was actually a step back from Dual Link DVI. For the most part those of us who owned these beautiful 30" monsters were now orphans--HDMI would only support 27" monitors.

    At least that was true until the 4K standard came out and and then new computers started packing extra high powered graphics cards and DP ports to support them.

    Apple developed the Mini Display Port to Dual Link DVI adapters to allow people who had the super-duper 30" monitors to hook them up to the new systems that could now support them.

    So I bought a Mac Mini to use with my HP LP3065c and got the adapter to hook them together. Most other reviewers had a hard time getting the adapters to work. Mine is the 3rd generation one with version 1.03 firmware, so that might make a difference. The problem seems to be from a lack of power.

    The Dual Link DVI adapter has two plugs on it: The mini display port plug that carries the video signal, and a USB cable to provide the power to the whole mess. Unfortunately there sometimes isn't enough power in the host computer to take care of it. The solution is to not plug the usb into the host computer, but to use a little usb power pack. I used my I-pad power pack ($19.95 at any best buy or Mac shop). When I did it all worked perfectly. Another reviewer said that you need one rated at least 1 amp. The I-pad one is rated 2.4 amps which is more than enough power.

    I didn't even try to hook the USB up to the Mac Mini. I just used the power pack when I first hooked it up and shezam, it all worked perfectly and my Mac Mini's display is shown beautifully on my 30" screen.

    If you have one of these monitors, you can't take advantage of the graphics by using the HDMI port. You need either one of the new display port computers, or one with Dual Link DVI output, which is usually only found in higher end graphics cards.

    I did have one incident where the monitor refused to display the output of the Mac Mini, and that was when I bought a new one of the little adapters from Best Buy. The new adapter didn't work the 2nd time around, so I swapped it back out with the old one from my I-pad Air, and everything worked fine again.

    Good luck with this product if you are buying it.

    I kept all my receipts and boxes just in case it didn't all work. You would be wise to do the same thing since YMMV.

    Surprisingly, I had no issues!

    After reading all the reviews on here, I was terrified to try this cable out. But since I just bought a new 2013 macbook pro retina 15" and there are no other options to use it with my mac 30" cinema display, I bit the bullet and bought it. I'm actually surprised that I've had no issues with connection and resolution. Works just fine (for me at least!)

    Works great

    Have this plugged into my Late 2011 Macbook Pro, Hazro HZ27WD 27" 2560x1440 monitor and a powered USB hub. Works flawlessly so far and I didn't have to configure anything. Shame these kind of adapters are so expensive :(

    Works Great! People with 1-star reviews were using incorrectly.

    I'm using this adapter right now from my 15" mid-2012 rMBP to a QNIX QX2710 LED EvolutionⅡ2 27" 2560x1440 PLS Monitor, which states on the seller page on ebay that it is "not compatible with laptops and mac computers," and that "Internal GPU, APU, and low-profile GPU are not compatible." The rMBP uses a GT 650m low-profile GPU. It later states not to use a port converter (eg mini dp -> dual-link dvi), this warning does not account for active adapters like this one, which uses a usb plug to provide additional power. If cabling permits, plug the usb port INTO AN OUTLET to ensure that it's receiving sufficient power. In any case, don't plug it into your laptop, run it off battery power in integrated graphics mode and write a one-star review when it doesn't work.

    It works with New Macpro 2014

    I almost did not buy this due to all the negative reviews but i had no choice. I purchased the new macpro 2014 but needed a solution to run the 30 inch cinema display at max resolution 2560. The adapter works perfectly. I had no issues.

    Make sure to get the version with Firmware 1.03!

    I use this adaptor on my 2010 Macbook Air to connect to a Dell 30" monitor. The first adaptor I bought would flicker and cut out, but after reading this (support dot apple dot com/kb/TS3232) I returned it and got a newer version with firmware 1.03 on it and now it's FLAWLESS. Zero problems and worth every penny.

    Just buy the thing and if it doesn't work, return it!!

    I hesitated to buy this because of all the bad reviews and then just thought to my self: "Just buy the thing and if it doesn't work, return it!!"

    You definitely have to have the usb chord plugged in to work.

    I'm updated with all the latest software on my early 2011 MBP. And it WORKS PERFECTLY! No problems at all.

    With my older 2007 MBP the screen would show those horizontal streaks of light that others have complained about. And this was BEFORE i got this adapter.

    The streaks would get worse and worse as the monitor was left on longer. So far this has not happened at all with the new adapter.

    So:

    Just buy the thing and if it doesn't work, return it!!

    Amazing cable

    Works great. Was able to output from MBP Haswell through the 2 thunderbolt outlets to two 5MegaPixel Barco mammography grade monitors. Flicker-free and seamless.

    Works fine on Dell 3007 and latest MBA

    I've had very few problems with this running my Dell 3007 monitor. I also run 2 other screens via display link (so 3 external including this one).

    A lot of people complain about the cost of these, but if you look at the market place and other manufacturers prices, the apple cost of one of these is actually OK. As the signal conversion between dual link DVI-D and mini DP is not straightforward, there is a chip inside these that has to convert the image, and if running at 2560*1600 at 60Hz, that is 245,760,000 pixels per second it has to do - hence the power requirement of USB and the cost.

    Works Perfect

    I don't usually write reviews, but I felt like this product needed a good one. I bought a 27 inch monitor for my job and found that I couldn't get its full resolution from my MacBook Air. I purchased this adapter, hooked it up and it works great! Picture is crystal clear, color is accurate. Like most Apple products, it simply works. Period.

    NEEDS a DVI-D dual cable!!!!

    IMPORTANT: make sure you're using a DVI-D dual cable!!!!!

    I initially used this with a regular DVD cable I had laying around, plugging my MacBook Pro into one of the three DVI-D on the back of my hp LP3065 30" monitor. I got all of the scrambling and other issues way too many people are reporting here. As soon as I found the DVI-D dual cable that came with the 30" display, it was all simple plug and play!

    To tell the difference, a single-link DVI cable has 3 pins, a gap, and then another 3 pins whereas a dual link DVI cable has pins running all the way across with no gap.
