Horizontal actives beyond 2048
pixels require a reduced vertical
active limit. Vertical actives
beyond 2048 lines require a
reduced horizontal active limit.
Required limit reductions shown
in table. Horizontal actives
beyond 4096 pixels repeat the
information contained in the first
4096 pixels of each scan line.
