LCD screen connection via vga type connector

Hello, I am trying to connect LCD monitor to the parallax chip using VGA type connection. I have to use as few pins of the parallax chips as possible for that task. from the schematic diagrams of the Propeller professional development board i noticed that 8 pins are required on the parallax chip to connect monitor using vga. Six of them uses red, green and blue color pins via different resistors. I wonder is that the only possible way for these pins to be connected. Can the number of pins used can be reduced in any way? I have attached the schematics, the diagram is in the page 7. If anyone has any ideals pleas share. Many thanks

Kind regards,
Mindaugas
