Some people may
be unaware that low refresh rates may cause eyestrain
and fatigue. Many users have the refresh rate
set to below 75 Hz even though their systems are
perfectly capable to handle higher refresh rate.

What is
refresh rate?
Refresh rate means how many
times per second the screen is refreshed (redrawn). It is
measure in hertz (Hz). The old standard for monitor refresh
rates was 60 Hz. Newer monitors usually have the refresh rate
of 75 Hz or higher. In order to avoid flickering the refresh
rate should be no less than 72 Hz. In general, the
faster the refresh rate is, the less the monitor flickers.
How do I know the refresh
rate of my monitor?
Here's a step by step guide
to identifying and changing the refresh rate of your monitor.
Minimize all windows and right-click
anywhere on the desktop. You will see the
pop-up menu like the one on the right.

Go to Properties.
Click Settings Tab.
|
 |
|
Then click Advanced button.
|
 |
|
In the next window click Monitor
tab.
|
 |

Under Monitor Settings
you can see the drop-down menu with the choice of
the refresh rates. It is a good idea to hide
the modes that your monitor cannot display.
Check this box before changing the refresh rate.
85 Hertz is the highest refresh rate that my monitor
can display. You might find out that your refresh
rate is set to 70 Hertz or even lower. If so, check
out if there are higher refresh rates in the drop
down menu. Consider 75 Hz or higher. After
having increased the refresh rate you may be pleasantly
surprised to find out that the monitor is now easier
on your eyes! First check the manual for
both your monitor and graphics card and
see what the highest refresh rate that they both
support and adjust you settings accordingly.
