appears by clicking [Advanced settings] in [Screen resolution]. Click the [Monitor] tab, select
a desired refresh rate from the pull-down menu of [Refresh Rate], and click [Apply].
・About refresh rate
A refresh rate means the number of renewal of screen performed for 1 second. If a refresh rate
is high, the flicker of a screen can be suppressed. However, note that the higher the refresh
rate, the lower the drawing performance.
The LCD monitor does not require high refresh rate compared with a CRT monitor because its
after-image persists for a long time.
The maximum of the refresh rate depends on monitors to be connected.
※You can use [NVIDIA Control Panel] to specify multiple displays, screen resolution, color depth,
and refresh rate. See the next section for details.
