Once that's done, the rest of the problem becomes trivial. It would be easier (and probably faster and cheaper) to lurk on Ebay until you can find a four-port PCI video card. -- Mark </blockquote></div>A: This framebuffer idea seems to be the closer one from the ideal solution for this problem, given the circumstancies. A couple of people mentioned it to me today (some from here, some from my college), but I appreciate your data about the monitor's frequencies, it'll be very useful once Im reporting my progress and obstacles to my boss ;) The thing about buying on eBay, as I said before, is that its not easy to get money released from the government to buy stuff for such an unusual project, let alone tell them we're not buying from a store or a company, but from a online commerce website... It'd never be approved; The contract would have to be made with some company, in order to be supplied with x LCD monitors (at a lower cost, obviously, due to the ammount required).
