Right now I've got a dual-DVI PCI-X card that runs two LCD screens on my PowerMac (the 256MB variant that shipped with the 2.0 DC). However, I just recently purchased a 37" LG LCD to replace my aging tube TV and I'd like to output my Mac to the LG to watch movies, etc. And at the moment, I have to unplug one of my smaller LCD's and run a cable to the LG... it works, it's just annoying. Can I add another video card to run the LG and if so, what card? Can I have the output on my LG mirror what's on one of the smaller LCD's instead of extending my desktop?
