    You may need something more muscular than an AtMega32 to generate an RGB signal.

    The frequency is somewhat variable, as is the quantity of data sent. Think of an 800 x 600 display, and then the 14,400 x 900 I have on my monitor. 480,000 pixels in the first case, 12,960,000 in the last. Then imagine sending all that data at a rate of 72 Hertz.
