Jeff, this is where you are flat out wrong. A LCD pixel will maintain a
persistent state as long as it receives signal. Unlike CRT technology,
which requires the electron beam passing over it to glow, LCD has a
consistent back light. When a pixel is told to show up as 'light pink' it
does not fade out, change, or do anything else until such time as it is told
to go to a new state.
There are no artifacts with this, there is no reason for there to be. The
conclusions you are drawing in comparisons of completely different
technologies are not accurate. LCD is not 'scanned' at 1/60th of a second
like CRT (give or take a bit). They are all put up as quickly as physically
possible by the LCD panel. 1/5000th of a second - 1/10,000 of a second.
Yes, each pixel is processed individually, but saying that is 'like CRT' is
like saying a Yugo is just like a Ferrari because both have four wheels and
can get you from point a to point b.
The underlying characteristics that make digital displays progressive format
by nature, is the same that allows them to accurately display lower refresh
rates with a filmlike effect that has been unseen before.
