The rate at which your monitor updates is measured in Hertz. One Hertz is equal to one cycle per second. If your monitor is set to update at a rate of Hertz, then it is refreshing times per second. The Hertz used to measure monitor refresh rates is similar to the Gigahertz used to measure the speed of your CPU, except that Gigahertz is a measure expressed in billions of cycles per second.

While some people are comfortable with around 30 Hertz, others can see the flickering and require a higher refresh rate. The most common refresh rate is 60 Hertz. There are other factors that can cause screen flickering and I have mentioned those at the bottom of this post. The refresh rates that you can set for your LCD monitor are largely determined by the capabilities of your monitor. While some LCD monitors can take advantage of several different refresh rates, others are confined to just one or two.

If you are on Windows 8 or 10, just right-click on the Start button and choose Control Panel. Click on the Monitor tab and you will notice a few things.

First, notice the setting labeled Screen Refresh Rate. This is the current refresh rate for your LCD monitor. Click the drop down menu and Windows will display all of the refresh rates possible for your monitor.

It is likely that your monitor can only use one or two refresh rates, so this list may not be long. Some manufacturers build monitors that can display anywhere from 30 Hertz to Hertz. Normally, monitors with higher refresh rates will be more expensive. A common refresh rate for gaming monitors is Hertz.

For example, some new 4K monitors are cheap, but are only 30 Hertz, which can make everything look choppy on the screen. Also, a lot of monitors will show 59Hz and 60Hz and you can pick between the two. Clean it up and tell the user it's a newer model than the one they have.

If you're lucky you can even find one that's a bit bigger than the one they had. Everyone's happy, and it doesn't cost a dime.
