Note: The maximum calculated display pipe dot clocks were used to select supporting
resolutions/refresh rates from the VESA table. Memory bandwidth, simultaneous functions, and
VGA mode support were not accounted for in determining the resolutions supported. In all cases,
only single pipe was used to determine the resolution supported – LVDS is only supported on a
Single Wide Pipe B, and DVO and VGA resolution.
