What frame rates are output from the WFM series VGA outputs?

External VGA: Tracks the incoming frame rate, except that for lower frequency frame rates (30 Hz and below) the VGA refresh rate is doubled. The worst case VGA refresh rate is 48Hz.

VGA PIX MON: Tracks the incoming frame rate all the way down to 24 Hz. Many VGA monitors do not support the lower rates.

Note: The PIX G/Y, B/Pb, R/Pr analog output also tracks the incoming frame rate all the way down to 24 Hz. Many TV picture monitors do not support the lower rates.
