8 RADEON™ VE User’s Guide
Note
The RADEON™ VE offers Ratiometric expansion.
Ratiometric expansion (or digital panel scaling as it
is commonly known) expands a low resolution
image to fill a higher resolution panel. However,
Ratiometric expansion is only available on the
primary display. Therefore, if a DFP is set as
secondary, the extended desktop is disabled and the
resolution is less than the DFP monitor’s native
resolution. This causes the DFP monitor to default
to center mode.
