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).
