<DIV><FONT face=Arial size=2>How about GEM working the sync on a extended screen
and a Matrox TripleHead2Go. It gives you three displays + your laptop screen
(would not give you an extra on a desktop). Is external so you don't need a slot
on your computer and is very cheap (around $300). This is the most basic
solution, is this what you need?</FONT></DIV>

<DIV><BR class=webkit-block-placeholder></DIV>
<DIV>what mpeg decoder cards with 4 outputs from the same machine are you
refering to? I will need to get something like that for an installation, but
don't really know much about it.</DIV>
