Does anyone know if it is possible to run two 24" monitors with a macbook pro unibody. I purchased a matrox dualhead2go digital edition thinking that this would work but it is not allowing me the resolution i need. The max resolution i am trying to achieve is 3840x1200 which is 2 1920x1200 24" monitors.

You can attach one external display to your notebook.

??? Have never done it, but have you installed the latest Matrox driver software and utility - available here. And then read the owners manual for directions on setting it up?

It can be done...but it's expensive.

Multiple Monitor Solutions For The MacBook Pro

The article I linked mentions the "Matrox" product you have.

Clicked on the link for the drives and it showed none, then i call matrox and they said that i can not do it with the dualhead2go digital i need the dualhead2go DP (display port). I also called apple and they said that the max resolution for these computers were only 2560x1600, but the old macbook pros could do 3840x1200 so i do not understand i am not sure if they gentleman i talked to at apple knew what he was talking about.

The info Apple gave you would be related to the internal video card.
The info Matrox gave you would be related to the external dualhead2go video device.

I do not remember any MBP capable of a 3840x1200 resolution from the internal video chip.
As far as I can remember 2560x1600 has been the max for several generations and that available only with a dual-link DVI.

Maybe there may be some confusion here about this resolution goal. If you have 2 external 24" monitors...and if each is set for 1920 x 1200...and if the hardware is set for "extended desktop" (not mirroring)...then (1920 x 1200) + (1920 x 1200) = 3840 x 1200.

So you're not looking for a single setting of 3840 x 1200...it's (1920 x 1200 on 24" monitor #1) + (1920 x 1200 on 24" monitor #2).

Assuming the MBP has enough video ram to display two 24" monitors at this resolution.

Or unless there is something different about the "dualheadtogo" hardware vs. how monitor resolutions are normally configured with Apple hardware.

I think the dualhead2go displays them as one single monitor. I called matrox and talked to one of their reps and he said that i would not be able to do this with the version i have i would have to get the their new dualhead2go Dp (display port edition) which does not come out till feb of 2010. I think it has somthing to do with the display port resolution but i think i have found a way around this. I think if i get the triplehead2go and get the Mini DisplayPort to Dual-Link DVI Adapter and then run a dual link dvi cable into the triplehead2go it should work.

I have exactly the setup you mention. I used to have this with an old MacBookPro with a DVI connector on the side (really not sure which version that was), and that worked in combination with the TripleHead2Go with 2 DVI monitors on 3840x1200.

Now I have it with the DualHead2Go DP with the 17" unibody MacBookPro; both with 2 DP screens, and with 2 DVI screens (with 2 DP->DVI cables).

The DualHead2Go has been available since this summer, however it may take a couple of weeks to get hold of one.

Just to be clear; I'm running 1920x1200 on my internal screen, and 3840x1200 on the external screens (together) giving me a total desktop size of 3 x 1920 x 1200 pixels.

There is a small issue though with 3840x1200 and 10.6.2, please refer to my blog.

DualHead2Go DP with Macbook Pro

Thanks Claude! I have the DualHead2Go and one DP -> DVI cable. I'm still waiting on another DP -> DVI and the Mini DP -> DP. I had to order the cables from different distributors. Each seemed to be out of at least one item that I needed.

Your tip may come in handy when I get everything together. I have the 15" Macbook Pro unibody. I'm really hoping for the best with this solution.
