Hello...i have already got some info on how to make a 32 x 32. So, what would i need to do to make two 30 x 20s and synchronize them together. Kinda like synchronizing two Peggy 2 boards to work together. Your input is greatly appreciated 
Simple synchronization could be achieved by strobing a digital pin every refresh period. For more sophisticated data sharing, the serial port should work.
Please explain what you want to do exactly.

It depends entirely on the schematic you are working with. We need to see that before we can be more specific.
