Updating monitor; microsoft.support = microsoft.support
In general, modern PCs should automatically select the best, highest refresh rate for each monitor you connect.
Scroll down a bit on the right pane, and then click the “Advanced Display Settings” link to continue.
Click the “Display Adapter Properties” link under the display you want to configure here. To change a monitor’s refresh rate on Windows 7, right-click your desktop, and then select the “Screen Resolution” command.
When shopping around for a monitor, a higher refresh rate is usually better, but it isn’t always the most important thing to look for.
There are other important considerations like response time, color accuracy, and the monitor’s viewing angle.
