Default Re: PC Generated 405 lines question

Hi Trevor,
was the video waveform from the computer generated video DC restored before inserting the sync pulses? The black level has to be set to a specific level and then the syncs are introduced into the video signal.
Syncs should be 30% of the total P - P waveform.

DFWB.
