@bc

I use a Thunderbolt 27″ display with my new MBA 13″. No problems (knock on wood).

I have both the Kanex MDPC30 and Apple MB571Z. I use the Kanex to hook up my Cinema 30″ to my iMac 27″. The MB571Z sits in my “Apple Box of Shame”, along with the puck mouse.

Hi BC,

Don’t the new MacBook Airs have a different video setup via Thunderbolt?

I’ve tested with the 2010 Mini DisplayPort MacBook Air (no problem) and 2009, 2010 13″ MacBook Pros but not with a Thunderbolt port yet.

Please let us know how it turns out.

So… is it my understanding that buying Apple’s dual DVI adapter will solve the problem between my Apple 30″Cinema HD display, and new Macbook Air with miniport output (as long as I get v1.03)? Photography, Aperture, etc are important – so looking for a good high res solution. Or should I be looking for a Kanex MDPC30?

Good news for me!
I read a lot about this problem. I had the horizontal flicker problem on dark areas of my 30″ Cinema display. I thought it would never be solved. I went to my Brighton Apple Store and booked to see a genius. We plugged it all into my new 2011 Mac Mini. Problem Displayed!!
He went and got their desks v1.02 Dual DVI adaptor and the problem went away. They then got a new one v1.03 from the shelves and it worked. Exchanged it with that problem solved.

So go to yr Apple Genius!

Hi Mark,

People need this adapter for monitors with 2560 x 1600 pixels (30″ cinema displays or in my case HP LP3065). There’s some Dell large monitors as well.

Making the web work for you, Alec

PS. The latest version of this adapter (Rev. 3 and further) actually do work.

just wondering why people would waste money on the duel link adapter? looks like a DVI adapter with USB beside it?…. anyways my HDMI miniport adapter works just fine on my 20″ monitor via HDMI to DVI conversion cable. and it works fine on the gramps 55″ LED LCD TV.

I have the smaller one, and run a wacom cintiq off it.

I was always astounded by the quality of the colour off the wacom. Brilliant blue, holds a candle to my Mitsubishi CRTs, and might even be better.

That is, unless you use the displayport adapter. Via DVI on my old laptop… beautiful. Displayport adapter… horrible washed out, dim, bad white balance, fringing on the screen edges, and the blue is sort of turquoise.

I am fairly ticked off, and will have to buy one that actually works. I guess because it’s having to actually process the signal and emit it via DVI, this thing is just weak, doesn’t put out much amps. Probably need to find some mains powered box…

Hi Alec,

Thanks! It’s a reasonable stopgap measure until…

… I’ll still probably get a DisplayPort capable 30″ (e.g., HP ZR30w or Dell UltraSharp 3008WFP) at some point.

Once my business is profitable. :-)

Sincerely,

Hi Eljay,

That’s valuable information. I would recommend that people get the Kanex instead based on your report and this test.

I can’t believe Apple has been putting their best customers (who else has 30″ monitors) through this kind of hell.

On the other hand, the Kanex solution is relatively recent. I see my strategy of pulling back and using a 2008 DVI MacBook Pro as my primary computer for 1.5 years was a good one. Early adopter blues.

Hi Alec,

Just got the Kanex MDPC30 and hooked it up.

Initial experience is good. So far, none of the errant horizontal flickering garbage as seen with the Apple MB571Z.

Thanks bunches!
