ú Refresh Rate—HydraVision automatically
determines the appropriate refresh rate for your
monitor based on your model selection, as
explained above. You may choose different
refresh rates from the drop-down menu for each
monitor. In general, a higher refresh rate improves
display quality but lowers performance, because
the graphics system can only do a fixed number
of operations per second. The more time it spends
redrawing the screen, the less time it has for
other operations.
Current Settings:

resolutions, a virtual desktop will be enabled on
the monitor that is set to a lower resolution.
