the refresh rate is the frequency at which your monitor projects a new image to the screen. Typically I believe higher frequency or refresh rate is better, meaning the image on screen is refreshed more often.

I guess that depends on your actual system... but I would set it as high as you can.

Make a test for yourself also.. like something easy.. maybe open MS Word and print a bold letter D in a huge font, you can see what it looks like before.. smooth edges and such.. then change the settings and open the document again... notice a difference??

It's how many times the screen refreshes itself...if you set it low, (Under ~70-75) it'll hurt your eyes after a while when you look at the desktop. The only reason to set it low would be if your monitor or graphics card can't handle that high of a refresh rate at the given resolution. If you have a higher resolution, it's typically harder for most monitors and graphics cards to use a high refresh rate (My monitor can only do a 60hz refresh rate at 1280x1024 - it hurts my eyes too much, so I stick with 1152x864.)

Here's link to a site for just about anything you can think of. I entered "Refresh Rate' in the site search feature and came up with this.

The site (howstuffworks) has been invaluable in my learning process (still is). Browse around the site, you'll like it.

Hmm, I can really think of no good reason to have a low refresh rate, besides the monitor not being able to handle a high one.

Hmm thats true to a point, but I can think of one reason to avoid overkill, because REALLY high refresh rates seem to cause fatigue and problems with your eyes more so than a low one (we're talking 100+hz) Several ergonomic studies have shown that high refresh rates starting around 92hz (depends on the person) and above cause strange brain reactions that can lead to fatigue, sometimes interfering later in the day with your sleep. Generally dont bother going above 85hz as the effects of refresh rates beyond that aren't clear as of now.

This may be due to the todays monitors having some type of flicker pattern above 90hz or it might be due to the refresh speed itself.

Just one reason to use a high but not too high refresh rate.
