If you
want to upgrade your computer, the new monitor is the easiest way to
upgrade your computer, because if you have old monitor with new PC, your
monitor slow down the system to download image on the screen. The main
change with new monitor is the increased screen resolution, fast refresh
rates in which a monitor will refresh a image on the screen.
If
you want to change the refresh rate of your monitor, Right click
on Desktop > Properties > Settings then open
Advanced
options. Here on the Monitor tab, go to Refresh Frequency
list, Here you can change your Monitor frequency with new refresh
rate. The default frequency setting of old monitor is 60 Hertz, but
your monitor may support more than 60 hertz. First check your
monitor manufacturer documentation about your monitor supports. The
higher refresh rate reduces the flicker problem on your screen.
