    Sleep problems with firmware update 1.3

    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?

    Snow on screen when waking up, sometimes

    This product works fine 99.9% of the time with a new Mac Mini/Lion and a Dell U2711 monitor running at 2560x1440.

    The only problem is that when the Mac Mini I am using wakes up from sleep mode, sometimes I get a lot of colored video "snow" on the screen.

    I can remove this snow by power-cycling the monitor. (I am not certain the problem is due to the cable - it could also be the Mac Mini itself or the Dell U2711 monitor at 2560x1440 resolution.)

    I am using firmware version 1.03 of the cable.

    If someone has suggestions, or even a location for support for this, that would be helpful.

    Expensive and Bulky

    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.

    Poor

    Adapter version 1.03 bought 16/08/2011. Terrible noise interference on starting up. It is necessary to drop resolution to 1920 x 1080. Then back up to 2560 x 1440. Works fine until next reboot. Mac mini -> Dell U2711. Disgusting price for this item, even if it worked correctly.

    Microsoft like solution

    Sure it works but instead of plugging directly into the computer now I need two adapters plus it takes up additional USB port. A major hassle not to mention that it's expensive!

    Works, but not through an amp

    I was going to use this adaptor to send the signal through my HDMI equipped AV receiver via my 27" Core i7 iMac. This would not work and sent no signal to the TV at all, despite all my other equipment working fine through the amp, even my PC.

    It does work when connected straight to both my 42" Plasma and my 32" LCD though, so it must be some sort of handshake issue or issue with the power of the cable?

    Not particularly impressed with it overall, especially at the price Apple charges!

    MacBookPro and Dell U3011

    This dual link adapter did not provide the 2560 x 1600 resolution capable on the Dell U3011. My MBP is a mid-2008 with Nvidia graphics card 9400M and 9600GT. Using the minidisplay port to HDMI I could achieve 1920 and using the minidisplay port to VGA I could achieve even higher resolution, but still short of about 400x550 -- ish.

    I am going to return this product. And try the minidisplay port to display port cord. Otherwise, I'll be sticking with the VGA adapter.

    Weird behavior

    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.

    Lasted almost five months

    Worked fine with an HP LP3065 monitor, for a while. I was banging away at a document earlier this week and the screen went black. Thought I heard a very quiet 'pop' so I assumed it was the monitor. Not so. HP's trouble shooting revealed that it hadn't dropped dead. I connected the Mac to another monitor via another adapter. No problems there. Then I envisioned that call with Apple about this $99 adapter, then obviously the culprit. Is there another one you can try? Nope - this is the only $99 accessory that I have ever needed for connecting a computer to a peripheral device.

    I bought another one from Amazon. If you have a dual-link DVI monitor, you really don't have much choice but to shell out for this thing. Plugged it in (after checking one more time to see if the old one had fixed itself) and sure enough the replacement solved the problem. I called Apple then, and at least they are willing to ship a replacement, to arrive in 2-5 days. I guess I'll have a spare.

    Given the hassle I wish I'd sought an aftermarket mini-DVI compatible monitor (not that there are many of those). Apple really needs to examine its perspective on video ports. If the designers are going to demand an adapter, and Apple is going to charge a whopping premium for it, it should at least be a quality product.

    Video noise in black areas

    2010 MBP i7 2.66, 8g ram, 10.6.4, plugged into original 30" Apple Cinema Display. Same issues as others with 30" display, noise in any region that is black color. Also when waking from sleep to input password, 30" display has a LOT of noise until I type password and hit enter key. This is really unacceptable. My 2006 MBP with DVI had no issues driving this display for the past 4 years.

    Don'y buy to use in mirror mode!

    Buyers Beware!! Just bought this to use between a new 2010 13" MacBook Pro and a 2005 20" Cinema Display with a view to using it in 'mirror' mode - ie mirroring what's on the laptop to the larger screen, while leaving the laptop idle. Apparently it only works at the same res as the laptop - 1280 x 800 which is absolute pants on the big screen. Only buy this if you intend to use your second screen as extra real estate!

    It's a driver issue

    I got this for my Samsung 305T. Although it displayed properly, the screen would continue to flash. It was never showing the screen for more than a few secondss before it would flash dark again. Totally unusable. I tried connecting the USB to a more powerful source but that didn't help.

    I measured the current drawn from the device from the USB port and it never drew more than 200 mA, which should be fine for most computers with USB ports. I don't see how that could be the issue.

    I partioned my mini mac for Windows XP and lo and behold. There are absolutely no issues when running the cable and monitor using XP on the same mini mac. This rules out the problem being the monitor, cable or mini mac. The problem is the Apple driver, either for the adapter or for the integrated video. Since it works on XP, I'll keep the cable. But I can see why there are so many complaints!

    Needs fixing still

    I'm onto my 2nd adapter now and still getting issues with it. I have done the usual trick of plugging the USB into an iPhone wall charger. I am getting the horizontal flickers across black screens, strange distortion from sleep and occasionally it will flick on and off quickly. I am also on the latest firmware (1.02). If you are thinking about this adapter, I'd suggest waiting until it's all sorted out. Currently I wouldn't bother. From the information I've found on the internet, I gather it's an issue with software as the adapter works fine on bootcamp. Hopefully Apple are working on a software update to fix these issues.

    Sometimes works

    Expensive piece of hardware, but is amazingly flaky. I mean it works most of the time, but is subject to random problems is the form of messed up displays (get used to unplugging and plugging back in). It's a digital to digital converter but it produces artifacts that you would expect from a analog to digital converter.

    Seriously, can this not be done better?

    (yes I have the latest firmware)

    Flaky at best

    I was so excited to get my new 17" MacBook Pro until I realized that this "Pro" product didn't work with my 30" Cinema Display anymore without me dropping another $100. I then get the adaptor to find that it is really flaky, my screen flickers few times an hour and it just seems like the whole thing was an afterthought at best. Really, really disappointed that Apple did this to their core audience who spends the most money on their products.

    Found solution for Mac Pro 4,1

    I just bought this adapter to run two 30" Apple displays on a 2009 Mac Pro with GT120 video. At first I could get nothing from the mini display port using this adapter. But from reading the other comments regarding usb power, I tried connecting both the usb connector from the adapter and the usb connector from the display directly to the back of the Mac Pro (rather than connecting the display usb cable to the adapter case). That brought both displays to life in full resolution. Only been running a few minutes but seems good. Agree this is a very disappointing product, and as a very big purchaser going all the way back to Lisa (1983) I expect better of Apple.

    How to run with Dell 30"

    The is a comment from a gentleman in this thread that mentions the USB connection. That is the key. I have a 3 year old Dell 30" monitor that would not work with the adapter. I have noticed that none of these laptops have enough juice to power the USB devices on a chain of hard drives, etc. So I had purchased an AC adapter powered Tripplite USB hub. When I plug the USB cable from the Apple dual link adapter to the powered hub the adapter works fine so far.

    Summary: If you want it to work you need an AC adapter powered USB hub or similar device.

    Vertical stripes and pixelated screen upon waking from MacMini 2.53

    I should have read the reviews here first, as I too am experiencing vertical banding upon waking up my 30" cinema display from sleep (usually overnight sleep only). I just purchased a new MacMini 2.53 (server model). I have not yet attempted to plug the USB adaptor into a powered USB Hub, as other have suggested. But this cable cost $100, and it should work plugged into the MacMini, unassisted.

    I was tempted to purchase the new 27" iMac, but I did not want to part with my 30" matte screen. It has to be the cable, as my 30" cinema display never exhibited this issue plugged into my MacPro (2 year old model). The cable is the only variable here.

    Dual-Link DVI Adapter with Nov 2009 iMac and NEC MultiSync 3090WQXi

    The Apple Mini DisplayPort to Dual-Link DVI Adapter rates 5 stars for driving the NEC MultiSync LCD3090WQXi 30" monitor at 2560 by 1600 pixel resolution from my Late 2009 iMac. The problem is that I cannot calibrate the monitor color using NEC's SpectraView II software and the Mini DisplayPort to Dual-Link DVI Adapter. It appears that the Mini DisplayPort to Dual-Link DVI Adapter hardware and/or OS X software drivers do not provide for proper communication between the SpectraView calibration software and the display's internal processor. I have to remove the Dual-Link Adapter, install the Mini DisplayPort to DVI Adapter (Single-Link), and calibrate the monitor at a 1600 by 1200 pixel resolution. I then have to reinstall the Dual-Link DVI Adapter to get the 2560 by 1600 pixel resolution.
