PIPE_A_VERTICAL_TOTAL_DISPLAY_LINES:
This 13 bit field provides Vertical Total
up to 8192 lines encompassing the Vertical Active Display Lines, top/bottom border and
retrace period. The value programmed should be the number of lines required minus
one. Vertical total needs to be large enough to be greater than the sum of the vertical
active, vertical border, and the vertical blank regions. The vertical counter is
incremented on the leading edge of the horizontal sync. For interlaced display modes,
this indicates the total number of lines in both fields. In interlaced modes, hardware
automatically divides this number by 2 to get the number of lines in each field.

PIPE_A_VERTICAL_ACTIVE_DISPLAY_LINES:
This 12-bit field provides vertical
active display resolutions up to 4096 lines. It should be programmed with the desired
number of lines minus one. When using the internal panel fitting logic, the minimum
vertical active area must be three lines. For interlaced display modes, this indicates the
total number of lines in both fields. In interlaced modes, hardware automatically divides
this number by 2 to get the number of lines in each field.
