Display Surfaces
A surface is a block of memory assigned to one or more physical display devices.
13506BMP provides 7 display surfaces (0-6) which cover the possible combinations of
display types. Table 1:, “Display Surfaces” lists the predefined display surfaces that may
be selected.

Display surfaces 0 through 2 each display data from a single memory block to an individual
display device (LCD, CRT, or TV).
Display surfaces 3 and 4 output to two seperate display devices, but generate the output
from the same memory block. This may be useful when the same image is to be displayed
on both display devices. It also reduces the total amount of display memory required.
Display surfaces 5 and 6 output to two seperate devices from different memory blocks. This
allows two completely different images to be displayed at the same time. When using
display surfaces 5 or 6, some combinations of display modes with a high resolution and/or
high color depth may not be supported within a 2MB display buffer.
