    USB Port Stopped Working after Mavericks Update

    Adapter worked well with my 2011 13" MBP on Mountain Lion. USB port on adapter no longer works after upgrade to Mavericks. Both USB ports on MBP work when not docked.

    hit and miss

    I have two of these, both connected to different Dell 30" monitors and used with the same 17" macbook pro. One works well with no problems. The other one requires unplugging and plugging back in the USB cable, or the display connector cable, 98% of the time when first connected, or when waking from sleep. The monitor comes on, but is fuzzy like a snow storm and the unplug/replug (sometimes 2-3 times) is necessary to get a clear picture. Its annoying, frustrating, and the first really poor product I've purchased from Apple in my 19 years of business with the company. Given the high price of the cable and that its OEM, I expect more. I've put up with this for over a year--it time to start searching for an alternative.

    Fine at first, now won't wake up my monitor most times

    As the title suggests, the cable worked fine at first. However, over time, it has stopped waking up my monitor when I turn on my computer. I know how to turn my computer on 4 or 8 times before it will wake up my HP LP3065. And I don't suppose that hard resets of the computer are good for it long term. Very disappointed. I will see what the Apple service line will do for me. I did buy AppleCare.

    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?

    When it works, it's great. When not, it's annoying.

    I use this to connect my 11" Air to a 27" WQHD non-Apple monitor (I had tried HDMI and regular DVI adapters and couldn't get full resolution). Most of the time, the D-L DVI adapter works fine and the picture looks great.

    About 1/10 times if I wake up my monitor from sleep, it looks great for a second or two, but then overlays the entire displayed image with a weird static. You can still barely see the picture, but you wouldn't want to use it. To recover from this, I often have to unplug the adapter from my Air and try again, sometimes multiple times are required. Also, it uses up a USB port and the pass-through one it provides does not provide much power: a mouse works, but the USB->Ethernet adapter does NOT work, nor does the external superdrive.

    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.

    Flicker

    Connected to the Cinema HD 30", to the iMac LED 27".

    The adapter works, but the screen has scattered horizontal flicker (graphical artifacts that last for, oh, 1/60th of a second) that is very, very annoying. Especially visible with a darker background.

    Disappointed. Gave the produce 2 stars instead of 1 star, because it is makeshift usable.

    One of the other posters said that they switched to using a powered USB hub and his problem went away. Tried using a Belkin powered USB hub, but that did not change the flicker issue.

    Firmware version 1.03. Hopefully the problem will get fixed with firmware version 1.04.

    Buy a powered USB Plug

    I encountered the screen flickering issue mentioned by other users, but fixed it by getting a powered USB hub that I plugged the USB plug from the dual-link DVI adapter into.

    Because the dual-link adapter doesn't work properly without a separate powered USB connector, I give this product 2 stars. It's basically junk without the powered USB connector.

    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.

    Works, but flickers and dies unexpectedly

    I read all the bad reviews, but had to buy the adapter anyway -- when I upgraded from my old MacBook Pro to the new MBP with mini displayport, this adapter was the only way to get my 30" Dell monitor to work.

    I never had any problems plugging the DVI directly into my old MBP, the monitor was crystal clear and never had a single issue. Since using the adapter, there is a constant flicker of red, green and blue pixels that are hard to notice, but if you're looking at a very dark screen they're very apparent.

    The adapter will also just die at random times, displaying a distorted picture, vertical lines, or both. I'll have to completely disconnect and reconnect to get it running again.

    For $100, you'd think it would be made better. Very disappointing especially since it's the only way to get my MBP to work with my monitor.

    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!

    New Macbook Pro and Display Connectors

    I just bought a new Macbook Pro with the i7 chip. It's a screamer and works beautifully in almost every respect but the display connectors. My old Macbook Pro had a full size DVI connector that directly supported every display mode I needed out of the box. Now to support my 30" Apple Cinema display I need this clunky connector? Really? To top it all, I bought the mini display port to DVI only to discover it's DVI-D (single link) not DVI-I. Every VGA to DVI adapter in my school is DVI-I so I can't connect without another adapter! So in the end I'm going to have to buy 3 connectors: mini displayport to dual-link DVI, mini displayport to DVI and mini displayport to VGA. A total of $160. For a company that has a reputation of attention to detail, Apple failed on this one.
