Question 1

I would like to be able to use the USB port for power or an AC power cord that plugs into a wall outlet. (I am in the USA) Is this possible with this unit and where would I purchase the power cord?

Thanks,
Mike Sparks

Accepted Answer

Hey Mike, I bought this a while back and it does work with a wall outlet. I used and old iPhone charger.

Question 2

I would like to run two (Non-Thunderbolt) Apple Cinema Displays from my 2009 Macbook Pro. Will this work?

Accepted Answer

Sorry I can't directly answer, but I can tell you that I've run this from a 2011 MBP and a 2014 MBP (both w lightening adapters) to 2 Viewsonic 22" DVI monitors, and to ASUS 27" and Viewsonic 22" DVI monitors successfully.  I also pre-tested a couple of well-rated USB to DVI converters and found their lag unacceptable.  Settled on this instead, even though a bit more costly.  There is a small bit of movement lag thru this, but not nearly as bad as the USB adapters, and certainly  acceptable for my daily spreadsheet, web, and email work.  The thing is built like a tank and reliable, and has decent control panel software for desktop location, splitting, & control.

Question 3

Has anyone using one of these on a MacBook Pro ( Mid 2012 ) upgraded to 10.9, and if so any issues? I have seen a few articles that the OS update broke multi screen functions.

Accepted Answer

I have a Matrox Duall ME for my MBP (2011) and using OSX 10.9.

It runs great for me.  The graphics are clean, and I can watch videos on both my monitors and my MBP with no lag or issues.

The only issue I have is playing a game or maximizing a page.  For some reason, when they go full screen they show on both my monitors (instead of just one of the two screens).

But I believe that issue is with the OS, not with Matrox.

Hope this helps

Question 4

Will this work with a MacBook Pro (Mid 2012) and 2 Dell U2412 monitors?

Accepted Answer

Yep...works great!  I use it with my macbook pro w/retina on Mountain Lion and now on Maverick with no problems.  I can use it with just the two monitors or with the macbook's monitor as a third screen down below in the middle...just drag the screens around until the config suits your style.  I go straight up onto the other two monitors like it's one big destop.  I have two 24" monitors above and the 15" below in the middle.  A little expensive but it was a fair price and it works very well.

Question 5

Anyone heard of or suspect any compatibility issues with Yosemite? I am currently using an ArkView product that turned out to have software compatibility issues.

Accepted Answer

I know nothing about Yosemite issues. I never managed to get it running completely smoothly on Mavericks, and eventually dropped it when I bought a 27" monitor that was too high-res for the converter. In hindsight, the solution might have been as simple as replacing a cable, or as hard as getting Apple to reveal more of its API to 3rd party providers -- my DisplayPort link has never managed to work work properly with Mavericks, which is the main reason I bought the Matrox in the first place. I am torn between selfishly advising you to try it with Yosemite and tell me how it works, and cowardly advising you to let someone else try it first. Sorry, I wish I could tell you something more honorable.

Question 6

I use a 2013 MacBook Air with a single Thunderbolt adapter.  I'm also using Parallels, and currently have a configuration using the Diamond USB Adapter.  I have Mavericks, and the Diamond adapter lags incredibly bad when I put my mouse over it.  I can't use it all the time, and typically leave my email up on that screen as it gets annoying to use.  I am constantly connecting to client sites and require the user of a third monitor, however I want to ensure that this will allow me to use the two monitors attached to the Matrox system independently.  From everything I read, it makes it appear as ONE giant monitor, instead of two separate ones.  Can anyone confirm if it is possible to set it up to allow two separate screens using Parallels and Windows 8.1? Thanks for your help.

Accepted Answer

I use windows 7 on parallels - in it's own window - this allows you to move it around to wherever you like(you can fill a screen with it if you like).  Windows 8 should work (as well as win 8 can work...) within these parameters.  It is one giant monitor - in my case using all three screens - two big monitors above and my laptop screen below.  I won't however say you can't do what you are asking.  But if any piece of hardware will do what you ask - this is likely your best shot at it.

Question 7

Currently I have a mdp>hdmi adapter out of my MBP going to my receiver, then out to my tv.  It also carries the audio so I can watch movies from my MBP on the large tv.

I want to add another monitor.

1) can I use a dvi>hdmi converter to get video signal to receiver (hdmi  inputs only)

2)will audio be carried?

Accepted Answer

I am saying I don't own any Matrox yet.  Thinking about a purchase.

And by receiver, I mean just that, a stereo system receiver thats hooked up to my computer via hdmi cable (which passes audio as well).  My stereo receiver only takes hdmi, not dvi.

I want to add an extra monitor to my current set-up but I don't want to lose audio to my stereo.

In the past, by running mdp>dvi>hdmi conversions has always seemed to lose audio when I try to complicate the connections with these adapters.  Trying to find the cause of the lack of audio is exhaustive.

But even before audio, I need to know if a dvi>hdmi cable will pass video to a tv.  I can run another audio cable if necessary.

Question 8

can i use this with a VGA connection if i can an adaptor?  I'm running off a mac and want to run two projectors?  if not this one what is my best option?

thanks!

Accepted Answer

Yes, you can run any connection you want.  I am currently running 2 monitors.  One I am using a HDMI cable, the other a DVI cable.  My computer is a Macbook Air.

Question 9

can i use it in portrait mode?

Accepted Answer

It does have a setting for it - I have not however used it.  This is fairly versatile and seems to beat anything else on the market.  I have been using it with two screens and my monitor for some time now and have had no problems at all.  I have two 26" screens and the Macbook pro screen directly below and in the middle (monitors are raised).  It acts as if it's all connected into one big (T shaped) screen.  You can position things however you like.  It appears as though you can change display orientation and aspect ratio on just the two upper screens if you like.  I've had an enormous amount of windows open at the same time with no lags or issues.  I also use parallels from time to time in its own window.  Hope that helps!
