The scenario is one computer (Win2000) currently with a dual-monitor (AGP) card. Will be adding one or two PCI video cards (no more dual-monitor cards as I don't like the display quality on the secondary monitor) and was wondering if there is any problem having a single program like Realtick or Cybertrader utilize all the cards so that it can spread it's display across all the monitors. An alternative approach would be to eliminate use of dual-cards and simply use 3 or 4 standard single-monitor video cards (probably all from the same mfg). Can a program talk to 4 separate cards and display as one unified program across 4 screens? I assume it's not a problem but are there any caveats I should know about? Thanks.
