Question : Problem: Multiple Monitors on one computer

Hi,
I am furnishing an office. The vision is to have instate of pictures some five 21 inch screens hang on the wall. The issue is that if I buy 21 inch digital picture frames I will be a poor man ($1300 a piece). So I see there are 21" screens for about $200 the question would be can I connect all 5 to one computer and then have a slide show and/or videos show on these 5 screens. The idea would of course be to have different stuff of each screen.
Wile at it did any of you ever hear of something wireless to get 5 screens work?
Basically the idea is to hang these 5 screens around the office and have some sideshows with music and some videos run all the time. Of course it is an issue with cable but this could be worked out. But I would like to be able to manage this from a single computer.

I would be happy if someone could give me some opinions or tips on how to archive my goal.

Best wishes,
thom

Answer : Problem: Multiple Monitors on one computer

Multiple monitor video cards are available. Here is one such link to some:

The problem would be syncronizing audio to the different screens. I have not heard of a multiple output audio card yet.
