Not enough hertz hurts: Here's an important tip from the Hot Deals Maniac.
After speaking with a few of my friends, I noticed that hardly anyone updates
the refresh rate on their
desktop computers. From someone who spends a lot of time looking at a
computer monitor, let me tell you how important it is to maximize the refresh
rate on your monitor. First off,
understand that the images that you see on your monitor right now are
not static images - they are not like looking at a painting on the wall. Your
monitor actually draws the screen
several times a second, kind of like a fast strobe light. The frequency
of refreshes per second is referred to as hertz. Most monitors support a
minimum refresh rate of 60Hz, which
means the monitor will flash the screen 60 times each second.
Since the flashes are done so fast, your eyes tell your brain that
there are static images (and text) on your monitor. However, if the refresh
rate is too low, your eyes can become very
stressed over time. Continued eye strain over long periods of time can
cause serious eye problems. How do you know if your eye is strained? It's
simple. If you stare at a monitor for
more than a few hours at a time, and if your brain starts to hurt (like
you have a small headache), your eyes are under too much strain and must be
given a rest.
How do you minimize eye strain? The best way is to increase the refresh
rate on your monitor.
Based on a poll that I did to a select group of people, here's the
refresh rates that I discovered and their relation to people feeling "eye
strain":
60Hz - 2 hours of casual use
75Hz - 4 hours of casual use
85Hz - 7 hours of casual use
(I mean "casual use" because the test subjects were not staring at
their computers for the entire time, but were for most of the time - in a
workplace.) Note that this was a personal
survey of a few friends, and should not be considered as an official
guide to "eye strain" in any way.
Okay, so now you know, but how do you check your refresh rate? In
Windows 95/98/ME/2000, right-click on the desktop and choose Properties. Click
on the Settings Tab, click the
Advanced button. Click the Monitor tab. Check the Refresh Frequency
setting. On some Windows OSes, you may have to make sure your exact monitor
model is in there before the
refresh rates show up. Under Windows NT 4, right-click on the desktop
and choose Properties, click the Settings tab, and the refresh rate should be
right there.
I strongly recommend a refresh rate of at least 85Hz at all times.
Anything less and you may be asking for trouble, especially if you are in an
office where you are staring at your
computer for most of your day. If your refresh rate is 60Hz, you must
must increase your refresh rate to something higher. 60Hz is extremely
unhealthy if you stare at your computer for
more than an hour at a time (est. 2 hours of casual use). Note that as
your screen resolution increases, the monitor's max refresh rate will
decrease. For example, my Viewsonic PS790
supports 85Hz at 1280x1024, but drops to 72Hz at 1600x1200. Lowering
your screen resolution will allow for a greater max refresh rate. I would
gladly sacrafice desktop space for an
85Hz refresh rate. If your monitor does not support a good refresh rate
at your desired resulution, I would consider purchasing a new monitor.
Note that laptop screens and LCD monitors may be much easier on the
eyes, because of their LCD displays. I do not know how the eyes handle staring
at LCD screens, but I do know
that most laptop screens have a refresh rate that cannot be changed.
If you do spend more than a few hours staring at a desktop computer
monitor each day, I strongly recommend looking at a refresh rate no less than
85Hz. Period.
Update (8am): An optometrist who visits this site regularly has these
comments. He says while increasing the refresh rate of your monitor will help
reduce eye

Hello Hot Deals Maniac,
Just a quick comment about your suggestions on maximizing the refresh
rate. You certainly are correct. However, there are several other
causes of asthenopia (eye strain) resulting from working at a computer
workstation. Please check out the following site which has a brief
article by a highly recognized and well published authority on computer
vision syndrome, James Sheedy, OD, PhD.
http://www.allaboutvision.com/cvs/
Then, go to:
http://www.doctorergo.com/allaboutvision/
and page down and click on "computer displays". It will give you some
other tips on display factors as well.
I practice optometry and see a fair number of people with these
complaints. I always discuss refresh rates with them but often other
factors play a major or very significant role in alleviating their
symptoms and must be addressed as well.
Hope this info is helpful. I appreciate and enjoy your website!

Jadi ya pilih yang refresh ratenya cukup baik.
