Rob is absolutely right.

The first thing you need to do is to set the size of the frame buffer
(where you are going to draw the different channels).

Edit globals menu is the way (Managed Area).

Every time you increase this value you can not download the combination
on the fly. You need to "save to EEPROM" and restart the graphics
(stopgfx;startgfx).
