How would one increase the refresh rate? I know my monitor can only do 60, at least that's what I think.
I'm using XP, so my screens won't be exact to later versions, but should be similar:
-Right click on the desktop and click properties.
-Click on the settings tab, or try them all until you see one that looks like it controls your resolution.
-Click on Advanced, or a button that brings up a tab-screen with monitor, adapter, general, etc on it.
-ON the monitor tab, you should find the video card's refresh-rate setting and can adjust it. It may do something funky if you are using the default "plug-n-play" monitor drivers, but sometimes it'll work. If you have the actual monitor drivers, it should work fine in all rates, with possibly a bit of resizing.
-If your monitor only has one refresh rate, it's too old and needs replaced.

Every monitor I've seen in the past fifteen years has multiple rates supported.
