My laptop has a VGA and an HDMI output, and I have the TripleHead2Go Digital edition. It came with a VGA/VGA connection cable and a DVI/DVI connection cable.
Right now I have three 24" monitors that I want to run at 1920×1080 each.
When I'm connected via VGA, the max resolution per screen is only 1280×1024.
Since my laptop has only HDMI, I've tried using an HDMI to DVI adapter, but either only one screen is picked up at 1920×1080, or the entire deal doesn't work and my computer flashes between the normal desktop screen and black.
Is there something that I need to adjust on my computer first to get this HDMI/DVI connection to work? Or, can I obtain a VGA/DVI adapter to see if that could work?

According to Matrox the TripleHead2Go Digital (the one with VGA input) has a maximum output of
Not 3x 1920x1080.
The TripleHead2Go Digital SE (displayport input) allows you up to 5760x1080 (3x 1920x1080@50Hz), but then you would need an active HDMI to displayport convertor.
And that assume that your laptop can generate the needed resolution.
Can you add the model of the laptop to the post?
