The company I work for has a setup using 4 computers and 4 lcds just to display some pretty low resource requiring information. What sort of quad display or even more can you get these days? I think ideally they'd want 4x VGA but DVI would possibly be an option. Is it cheap to do now? What are the best gfx cards to get for this? And like I said the stuff displayed is nothing special so any real graphics processing isn't required, it's mostly 2D maps with an overlay. Getting a card which could be mounted in a 19" rack PC would be the preffered option..
