    * Attention Mac Mini Customers using dual monitors only. There is an unresolved issue with using both the mini-DVI and mini display port outputs simultaneously. Specifically – when the mini-DVI cable is disconnected from the Mac mini, this causes the mini display port to not function  – often causing the display to show an “unsupported format” error. This appears to be an ongoing issue with multiple generations of Mac minis (models with mini-DVI and mini display port) and also appears to be happening with a variety of manufactures display adapters for macs, not just Monoprice adapters.


    The solution – (Again, for dual monitoring Mac mini users only) Use the mini-DVI output for your main display, and the mini display port for the secondary display. That way - disconnecting the second display (mini display port) will not affect the output on the main display (mini-DVI). This will not be an issue if you are using two monitors - and are not disconnecting your mini-DVI adapter.

    Will this adapter work with a Dell 3007WFP to a Macbook Pro 2015?
    A shopper on Sep 3, 2017
    BEST ANSWER: I have this model 300WFP but the adapter gives me the same intermittent interference problems as the Apple adapter which used to work fine, but seemed to go bad. The interference is just not so often (for now). Running at 2048 resolution. My next theory is that I have power fluctuations (both in the apple port AND the wall outlet? IDK?) but what I would do about that I have no idea. This unit seems lighter than the Apple one.
    is there a regular size displayport version of this?
    Christopher C on Nov 25, 2016
    BEST ANSWER: Hello, thank you for your question. Unfortunately we do not carry a full size displayport version of this item. I apologize for the inconvenience

    Issues and possible work around
    Like many of the other reviews, I had two main complaints with this product:

    1) Problems waking from sleep, and
    2) That the adapter consumes one of the precious USB connections in addition to the mini display port.

    Note that the Apple-branded adapter has many reviews with the same complaints, so I think this is more of a design issue rather than a quality issue. Although some say the newest Apple version with firmware 1.0.3 is better.

    I think I have come up with a work around that addresses both of these issues. The USB connector on the adapter appears to be for supplying power only. It also explains why the adapter freaks out when the computer wakes up: it is trying to both establish the video connection while at the same time, power is just becoming available through the USB connection.

    I simply connected the USB cable from the adapter to a spare Apple iPhone USB power supply. Now the adapter has continuous power and seems to wake from sleep without issue. Doing this also freed up the USB port on my MacBook Pro previously used by the adapter.

    I just did this today, but so far, so good. I'll update this review if things change.

    PROS: Connects a 30-inch cinema display to the new MacBook Pros at native resolution.

    CONS: 1. Does not wake from sleep well
    2. Consumes a USB port as well as the mini display port
    3. Runs a bit hot

    I initially went with the AMD certified active adapter, but kept getting an occasional DisplayLink Failure notice. The company says that their adapter isn't 120hz stable and suggested going back down to 60hz. This Monoprice adapter does 120hz with no link failures.

    PROS: Works perfectly and gives 120hz option without DisplayLink Failure. Cables are long enough for any setup.

    CONS: None

    Mostly Works
    I'm pleased with Monoprice's products most of the time and was happy to have a MiniDisplayPort / Thunderbolt to Dual Link DVI solution for appreciably less money than Apple's MDP/TB - DL DVI adapter. It is also smaller which is nice. Initially I was concerned with the product as testing with two regular Single Link DVI monitors yielded very poor results - at best the image was riddled with artifacts and at worst there was no display at all. However, my intent was to use the adapter with a Dual Link monitor, which I proceeded to, and the picture is wonderful! So personally, the issues with SL DVI don't bother me. However, when my Mac Mini (2012) goes to sleep, and I wake it, the computer wakes up, I can tell, but the display does not wake up. I tried a few things but the only solution is to unplug and replug the adapter to the computer. Not very friendly. I suppose I could tell the computer to never sleep, but that's not too convenient.

    However, it does mostly work.

    PROS: Allows a Minidisplayport or a Thunderbolt port to attach to a Dual Link DVI monitor.
    Much less expensive than Apple's adapter, and I think smaller.

    CONS: Seems to have issues with waking from sleep.
    Seems to have issues with Single Link Displays.

    Looses synch - defective design
    Unfortunately, this adaptor has a design flaw that causes it to loose synch resulting in the snowy screen several times a day. As you can see from these reviews, this is a common complaint. Monoprice was was cooperative in exchanging the unit for me but the problem existed on both. I also tested the units on two different monoprice monitors of the same model and two different macbook pros with the same results. So it's not just a defective unit. It seems to be a design flaw of some kind.

    Works, sort of, but...
    When the adapter works, it works reasonably well.

    Sadly, there are several situations where it doesn't work. I'm using it with a 27 inch iMac and a Dell 3007WFP. If I tell the iMac to "detect displays", or put it to sleep, or reboot, the adapter loses all communication between the computer and the Dell screen, and won't come back until I unplug the adapter from the iMac, wait a few seconds and plug it back in.

    There's an almost identical setup here in the office using the Apple adapter with no such problems (although I've seen plenty of negative reviews about the Apple model too).

    Not recommended.

    PROS: When it works, it works well, and it's cheaper than the Apple version

    CONS: Connection to the monitor disappears frequently

    So so product
    The product allowed me to connect a MacBook Pro with a mini displayport to my 30" monitor which required dual DVI. However, the results are far from satisfactory. When I was researching this adapter, I noticed that Apple's version of this product was pretty poorly rated, while the Monoprice one was rated much better. I opted to get this one and see that it does a very poor job. There are a lot of "shadows" around windows edges and more importantly there is flicker. Oddly enough the flicker is worse when the laptop is first turned on, but it does reduce after a while. I have no idea why this happens.

    I hate to think what the Apple's product is like, given the poor quality of this unit. Maybe, I have a dud? I have not had a chance to call Monoprice's tech support.

    PROS: Cheaper than the Apple product

    CONS: Lots of flicker and shadows

    For those of you wondering if this is an active mini DisplayPort adapter, it is! What a great deal at $30 less than anywhere else! I am using this to run 4 screens simultaneously (1 HDMI, 2 DVI, 1 mDP to DVI). This adapter allows you to expand your screen real estate using more than two legacy (non DP) connections.

    PROS: Easty to set up and is an active mini DisplayPort adapter

    CONS: None

    it works
    Works with my Mac Pro and Dell 3008wfp. Apple's crappy minidisplay to dual link dvi didn't work at all and this one works perfectly for 2/3 the cost.

    PROS: works as advertised

    CONS: none
    September 29, 2010
    This works exactly as advertised. One note: you also need to make sure that you're using a dual-link DVI cable to connect to the monitor. I initially tried (unknowingly) with a single-link cable which resulted in a very fuzzy image.

    PROS: * allows for high-resolution display on 27" and 30" monitors.
    * much cheaper than Apple's version.

    CONS: * ties up a USB port for power (so does the Apple version).

    Use for 3 DVI monitors on 2010 Mac Pros
    It makes everything work on a Mac Pro with the 1 DVI and two Mini-display ports. You CAN hook 3 DVI/HDMI monitors to your Mac Pro.

    I have two of these, and i have 2 DVI and 1 HDMI Sharp Aquos hooked into my Mac Pro now - zero configuration problems.

    You might want to spend $5 on a POWERED USB hub to power them instead of using up your USB ports on your Mac.

    PROS: Its $40 cheaper than Apple's adaptor which seems to not work very well per the reviews. And it works.

    CONS: none
