Super VGA monitors can support IBM standard VGA plus the 800x600
extended mode used by most VGA cards, and the 1024x768 interlaced
mode used by most VGA cards and the IBM 8514A.
Multisync monitors are more expensive and will work at all Super VGA
resolutions plus additional higher resolutions or refresh rates. The most
useful multisync monitor specification for determining maximum
resolution and refresh capability is the horizontal frequency range. For
PC use, the lower limit of the range must be no less than 30KHz. The
upper limit is usually 48K Hz, 57K Hz or 64K Hz. These correspond to a
maximum resolution of 1024 x 768, 60 Hz refresh, 1024 x768, 72 Hz refresh
rate; and 1280x1024, 60 Hz refresh rate, respectively.
By default, the card
will drive your monitor at a screen refresh rate of 60
Hz. In other words, it repaints the screen 60 times per second. If the
screen is not displayed properly when you boot your system, your
monitor may not support this refresh rate for the resolution chosen. In
this case, you must either lower the resolution to one that can be
supported at 60Hz or lower the refresh rate. The maximum refresh rate
supported by your monitor is specified with the Refresh Rate utility.
Refer to your manual for information on the monitor capabilities. If you
are not sure what refresh rate is supported, you can always try a higher
rate. If the screen looks good, the rate is supported (and will be easier
on your eyes).
