How can I tell which vid cards support dual DVI displays?

[dterrors]

Some vid cards support two DVI monitors via the use of a splitter
cable, even though they only have one DVI out. Do they all support
that? I never see it say so in the specs...

thanks

Look at a picture of the card. If it has two dvi connectors
then it will feed two monitors, it's as easy as that.

The DVI connector supports both single- and dual-link
forms of the digital interface it uses (called "TMDS").
It's possible that some cards could provide two separate
single-link outputs via the connector, but this is a non-
standard use. (Not that the DVI standard is all that solid
in the first place...) You can also, of course, simply
split a given output, preferably with an active splitter
(i.e., one which takes the digital signal and duplicates
it via a buffer).
