Hi together,

I'm successfully using the digital tripleheadtogo from my PC. Now I would like use all 3 monitors from my Laptop, too, disconnecting the dvi and connecting the VGA output of my laptop. I can only display 2 monitors (unfortunately the most left and the most right) even with latest matrox firmware, drivers, etc..
Can it be this is a bug at Matrox? Matrox quick setup detects and display all 3 monitors. If I adjust this mode it wants to make a restart, and comes back with error during applying the new settings.
Thank you in advance!!

Try applying the new resolution from the desktop. For some reason, Powerdesk sometimes has a hard time in changing resolution. Also, if you have two monitors active and they are on opposite screens, use the swap monitor (or swap screen) option in powerdesk.

May I assume you are using 1920x1200 or 1920x1080 monitors? This is the only real reason it wouldn't choose to use a TH resolution.

May also depends on the laptop GPU, it may not have enough RAM to support the resolution?

No, I have 3 x (1024x1280).
The question is why this error message of not beeing able to set the according configuation.

It's a Nvidia Quadro FX570M.
total 1407 MB RAM, video dedicated memory 128 MB, shared system memory 1279 MB, that should be enough if calculated it right. What do you think! :nudgenudge

Hi,
It is OK for me with Quardro FX570M,My laptop is Thinkpad T61P.
it can output 5760x1080 50HZ to our device through DVI output.

Please read the thread more detailed: I'm talking of VGA output instead of DVI! DVI is only available using docking station which I don't have at home.
