In Productivity mode, the pixel data come faster than the normal
de-interlacer circuitry and its RAM can sample them. You would need
much faster devices at exponential higher cost, so this was not done.

Same as 1).

Yes, the A2024 can only display 4 shades of grey. This mode is never
supposed to be used on a different monitor.
