    I've been wanting to run a triple monitor display from my MBP for the longest time and finally bit the bullet on Black Friday.

    I picked up a trio of 23in 1080p Acer monitors from MacConnection ($99 each!) and a Matrox TripleHead2Go DP Edition. After getting it all set up, I've run into a problem...

    Ideally, I want to run a 5760x1080 resolution (3X 1920x1080) from my Thunderbolt port to the Matrox GXM to the Monitors. However, I cannot get the MBP to output a higher resolution that 4080x768 (3X 1360x768). The Matrox GXM is capable of the 5760x1080 resolution and I'd hope that my 6750M would be powerful enough to run this resolution.

    I suspect the problem lies within the Apple driver for this specific card as other MBPs are capable of running the full resolution. My next attempt is to put bootcamp on the MBP and see if I can find a Windows driver for the 6750M. Any suggestions are welcome.

    It IS possible, and I have done something like this before.

    What you need are two USB video cards, and one Mini-DP to DVI adapter. Remember that gaming/full motion HD video should only be done on the main monitor (The one connected to the Mini-DP to DVI adapter).

    I purchased a DisplayLink adapter from EVGA and the OS X drivers worked flawlessly.

    Though you doing this setup makes me want to rethink my setup, and go for something like this now.

    But you don't get the full 1080p resolution. It should be amazing if H2G or Apple can fix this problem, I really wouldn't mind doing this for my setup as well.

    I looked into going that method before purchasing the Matrox box, but I really just wanted a simpler way with less cables and the ability to play BF3 on all three monitors without lag.

    Instead of 2 USBs and 1 mDP coming out of my laptop, I can have 1 mDP and 1 USB (powers Matrox). Plus I have the advantage of using my GPU on all three monitors.

    I have got a Triplehead2go DP as well, How have you got it hooked to the monitors? Have you done it by VGA or DVI?

    I wanna hook mine up to VGA for the time being, but I dont know what leads will work. On the Matrox website it doesnt have any info for the VGA side. I was wondering if you have tried VGA?

    Right now they are in DVI. I want to say that because it's the DP edition, only a digital signal will work (DP and DVI). So VGA might not be possible without the Analog edition of the TH2G. But that's a complete guess.

    oh screensaver thanks my first guess was you could select the album off that view like a cover flow alternative

    thanks for the reply

    Wow, your adapter costs more than your actual monitors! I want to get this also but I can't see myself paying for such an expensive adapter.

    Did you find out if you could run a 5760x1080 resolution (3X 1920x1080) with your MBP and the Matrox TripleHead2Go?

    I'm about to buy a Matrox TripleHead2Go Digital SE edition (I guess it is the newest one) but want to make sure my MBP late 2010 edition will work in 5760x1080 resolution (3X 1920x1080). I have Mountain Lion installed 10.8. Do you know if I could get this resolution working?

    Not much luck for MBP

    I have digital version and MBP with Retina Display (2012) technically you can only get 1600 x 900 x 3 @60

    According to technical specification, the highest resolutions are off ordinary refresh rates.

    5040 x 1050 (3 x 1680 x 1050) 2 58Hz
    5760 x 1080 (3 x 1920 x 1080) 2 50Hz

    means you need something 50hz with 1920 x 1080 support and this is most likely TV screens, not PC monitors. and usually the TVs don't have 1920x1080 support unless connected via HDMI cables (correct me if recent TVs do)

    Somehow it only support 1360 x 768 x 3 on mine too... It should support 1600 x 900 x 3 @60 at least by their technical specifications.

    does anyone know why ?

    Anyway 3 TV screens would be out of budget for most of us and to be honest 3 x 1920 x 1080 is yes doable on Macbook pro but "Gaming" is totally different story. I have GT 650M on my laptop (well, GPUs on laptops usually a lot worse than you expect by its "numbers") and still struggling to run 3 x 1280 x 1024 at good quality setting (not the highest)
