CitricI used to have a laptop and wanted to see if I could use it with a 120hz monitor and get 120hz. This was the most useful reply I got: http://www.teamfortress.tv/36444/laptop-to-external-display-is-120hz-possible#2
Display adapter properties doesn't do anything because my integrated graphics card is an Intel HD, but my laptop also has a GeForce GT 730 graphics card, so I'm not sure if that helps or not.
