<< The AIW cards support 1 crt or DFP monitor AND 1 TV or VCR. They do not support dual monitors. I use a secondary PCI card for dual monitors, and that works well, except the video-in functions are disabled while the secondary card is enabled, so no TV and no video capture with dual monitors. I do not know if the same is true for the AIW 7500 or the AIW 8500dv. >>
Funny thing, with my triple monitor setup I have the TV tuner On 19" monitor (I'm a financial consultant so I like to have the business news on as much as I can), second monitor 17" is my browser for keeping up to date stock markets etc, third monitor 17" is for my Email, contact manager, office, word etc.
My three vid cards are pretty much always activated and my video in, tv tuner and video capture have no problems what so ever.
rbV5 is right about the AIW cards, they do only support 1 crt or DFP monitor AND 1 TV or VCR. They do not support dual monitors so no choice to go to another PCI vid card to drive that other monitor, or monitors if you get a dual head that supports two monitors on the same card. Then you could have three monitors with only the two vid cards. Tv on one monitor and your photoshop and stuff on number two monitor. Then you can work on the image on number three monitor. Cool huh.
