Standard NTSC monitor and TV always show solid green, violet, blue and orange line in high resolution. Do you know if there is higher frequency monitor which it allows me to see dot line instead of solid line? Let say for example. Violet line starts at position 0 and ends at position 556. Violet dot is supposed to show 0, 4, 8, 12, and so forth. I would like to experience it. 

Just take a look with a good monochrome monitor and all the
structure of the video signal will be visible.


Michael,

Thanks for the information. I have one, but I still want color monitor that looks identical to monochrome so color line can be shown dot. 

You can look at both to see what color corresponds to the video
signal shown on the monochrome monitor.

There is no such thing as an NTSC "dot".  There are only
color artifacts corresponding to the position of a pulse
relative to the 3.58MHz color subcarrier.  When a series
of short pulses is interpreted as color, the color displayed
is not properly a result of the juxtaposition of several
very small color dots corresponding to each pulse.  The
whole "constellation" of pulses corresponds to a single
color dot.

A proper RGB decoding of the Apple II video signal will
similarly replace a "pixel" constellation with a single
color pixel as wide as the entire constellation.  To do
otherwise is to invent new graphics modes.
