Ergonomic Refresh Rates
The VGA controller is capable of displaying many
resolutions with a refresh rate (vertical scan rate) of 72
Hz, and can display some modes as high as 78 Hz.
These refresh rates eliminate almost all monitor flicker
detectable by the human eye. If your monitor is capa-
ble of using the higher refresh rates, you can use the
ALTPARM utility (described in Section 2, Chapter 2) to
change the display mode to one of those listed below.
Do not attempt to set a refresh rate that
your monitor is not capable of producing. Check the
that came with your monitor for details.
