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.
