Please find enclosed this PDF
not true - as i have a show - 'Keane" tour - running on a quad g5 with both triple and dual heads. i think rob has 4 or 6 outputs. I cant remember.

i also have a several g5's on other shows with these devices.
including 'waves' at the national theatre.

all the information from matrox has been inaccurate.
this pdf simply shows what matrox might have tested - not what works.

it depends on the graphics card - and it depends on the operating system.
there are no rules of thumb-
these devices also sometimes work at different resolutions on different machines.

if it works - it works - it if doesnt it doesnt.
you have to test it.
not every resolution is supported at every refresh rate - sometimes only 2400x800 works - sometimes only 1920x480 works.
