Reviews for Mini DisplayPort to DVI Adaptor

I bought a MacBook Air. I bought this adapter thinking I'd be set, since I already had a DVI to VGA adapter (from the macbook pro I was replacing). However, the two aren't compatible. The DVI to VGA adapter has four pins which this doesn't accept.

I'm not sure if the signal from this doesn't meet DVI spec or what but if I try to run above 24 Hertz on my projector (which I use with other computers at 60 Hz, progressive in both cases) I get intermittent static and blinking. I have a similar problem with a Dell LCD when I try to run it through an ioGear KVM. PCs going through the same KVM drive the monitor at the same resolution and frequency with no problem (even if I swap ports on the KVM to make sure it's not a bad port). I figured the Apple brand adapter would be the gold standard, especially based on price, but I'll have to try another brand of adapter now. Weak.

Pro: I can plug my monitor into the card through the Mini Display Port so I can still have both monitors.

Cons: There are a lot of times where either it doesn't work at all, the monitor rapidly cycles pixels on and off or the monitor looks like it has areas of dead pixels. Cycling the power on the monitor resolves the issue most of the time, so it's more of an annoyance. I tested both of my displays, it's the adapter.

This adapter provides a DVI-D connection. Most DVI cables and adapters I've come across use a DVI-I connection, which has four additional pins on one side (above and below the flat, horizontal pin). This adapter physically blocks those four pins, preventing a connection. I ended up having to buy a special DVI cable (as well as Apple's VGA adapter) to make sure I could always connect to a projector or display on the road.

Adapter works fine on a DVI monitor but will not put out the same signal as my old Powerbook. Using the old DVI to VGA plug that "CAME INCLUDED" with my G4 into the "NOT INCLUDED" Mini display to DVI adapter there is no VGA signal. But you can get a mini display to VGA adapter so the signal is there. WHY does it not carry through the DVI adapter the same as all previous Macs??

wondering why your displayport isn't working right? think its broken?
external screen is not recognizing your video signal? try restarting! i finally figured it out. I have a macbook pro unibody 15". displayport to dvi-d cord to hdmi. I returned my first display port because i thought it was broken.guess not, i have to freaking restart every time for the displayport to be recognized!

The package only says DVI. Now granted the baggie is clear and you can see the connector itself, but when buying a new Macbook Pro, I just asked for the DVI adapter, thinking it was as good as the previous DVI output on my last Macbook Pro. Why would Apple remove functionality from a product, right? I mean having to use an additional adapter (and not have it included with the computer) was bad enough, but why would the new adapter not support DVI-I, when all the previous ones did? Especially given that there appear not to be adapters for MDP that replace the ones available for the previous generation. I see none for S-video or RCA-out. I still need to be able to connect to all these things, not everywhere I go has modern video technology.

I understand the decision to remove the full-size DVI port from the unibody models, but not to fail to adequately replace it with the adapter. And then put a generic label on the adapter not indicating it's less compatible than what it's supposed to replace.

Oh, and I should mention, mine actually doesn't work at all. I think it might just be a defective unit, but I don't have another DVI monitor to test with right now.

This adapter is not compatible with the Cintiq. I didn't bother reading the other reviews before purchasing it.

It gets 2 starts because it looks really neat.

I bought this along with my new macbook, thinking that I could connect my VGA monitors via the old apple DVI to RGB converter that came with my mac mini. It does not work, as the old converter is DVI-I and the new converter is DVI-D. How frustrating! As others have pointed out, why on earth doesn't apple provide a DVI-I connection on this adaptor?

I was happy to see the results when I hooked up my MacBook to my TV, but then when I tried to use this adapter with an older Apple DVI-VGA adapter cable, no go. I needed to connect the two in order to use a data projector with only VGA inputs. Now I have to scramble to find another way to use the projector.
Apple Store employees should tell you up front that this adapter isn't compatible with older (analog) cables, but they don't. That's why there are MANY people with experiences like mine.
