        Should work. Remember, you can take a HiRes screen, so your
        resolution is still at least LoRes. (Don't know from heart
        how many grey scales you can get from this, sure not 256 :-)

        If you don't have extra hardware connected: NO solution.

        If it's 24 bits, then yes.

        NO, sorry.

        Those which really provide 8 bits per color component RGB,
        give you exactly 256 grey shades.
