Note
h
0…n cycles optional blanking (horizontal and vertical)
i
a. leading blanking before start of active frame area
b. leftmost scan dot of topmost line (start of active display area)
c. rightmost scan dot on first line, last scan dot of horizontal cycle for single and dual scan
d. trailing horizontal blanking after first line for single and dual scan,
for zigzag scan there is no blanking between rightmost scan dot of topmost line and leftmost scan dot of line number DualScanOffs
e. start of second line (leftmost scan dot) for single and dual scan
f. rightmost scan dot on second line for single and dual scan,
for zigzag scan this is rightmost scan dot on line number DualScanOffs, i.e. last scan dot of horizontal cycle for zigzag scan
g. trailing horizontal blanking
h. last scan dot of last line, end of active display area
i. trailing horizontal and vertical blanking
Please refer to section 3.9 for a more detailed explanation of display timing, especially blanking insertion.
