1 - The Basics
the early days of computing, a 60Hz refresh rate was usually the best we could get. It
was almost guaranteed, that after prolonged
exposure to the monitor, an eyestrain headache
was around the corner. Why? Because 60Hz is
the frequency of AC electricity (at least here
in the US, many other countries use 50Hz power).
With the refresh rate set to 60Hz, you will
probably notice a strobe or pulsing effect.
Over time this can cause eye fatigue.
are three things that determine what refresh
rate your system will support - the video card's
RAMDAC, the monitor's capabilities
and what resolution you are running. The higher
the resolution, the lower the refresh your monitor
can support. If you set a refresh rate too high
for your monitor, you can damage it. I remember
my "old" Lightspeed 128 only had a
135MHz RAMDAC - now cards ship with 350MHz RAMDAC's.
There are also typically recommended resolutions
for different monitor sizes; i.e. 800x600 for
15" monitors, 1024x768 for 17" monitors
and 1280x1024 for 19" monitors. Personally,
I use 1152x864 for my 17" monitor. The
higher the resolution, the more "desktop
real estate" you gain, but the text and
icons get smaller.
how do you find out what refresh rate your system
is currently using? Go toStart>Settings>Control
Panel. In Control Panel choose Display (Properties),
then select the Settings tab. It should look
select the Advanced button in the lower right
corner. From the next screen choose the Adapter
tab. It should now look like this
