LCD driver through vga

[gaums]

Hi guys, this is my first post. I have a pic16 driving an lcd and it works great. Now I want to drive the lcd through a 5ft vga cable. I have done the prototype using a two bread boards: one has the pic16, the other has the lcd, and the vga is used to communicate between the two (). The set-up works wel, but I sometimes get strange symbols. I checked the grounds on both boards and they appear to have the same potential. I don't really know what could be wrong. What do you guys suggest?

you can use max232 and implement serial interface between two pics..
you can send commands and data via serial interface to other pic with lcd from the first one..
and vga cable will be the phyiscal medium..
you need only 3 wire 1Tx 2Rx and 3GND for communication between them...
