Patterns are:

Filled screen

Fill all pixels with the same color. Just to check that your hsync and vsync signals are right.

Edge frame

To check that your timing and x/y coordinates are syncronized.

Checkboard

Well, it's nice and classic.

Color gradient

To display basic colors and its combinations.

Part II: Images

Draw images from ROM or RAM.
