I already sync my color wheel to my tristable switch. Why should I bother to sync each color wedge to vertical blanking?
ANSWER. I guess that your question is a matter of taste. Do you mind watching colored stripes on your TV? If not, then switch sync is all that matters. If you mind the stripes, then the wheel wedge must also sync with vertical blanking. At the start of the video field, the wedge should begin descending down the tube. I reread Stanley’s ideas on the subject. He tried randomly syncing the wedge and the TV display. That method didn’t work for him. (Stanley’s thorough discussion of color wheel adapters appeared in Radio-Television News.
