    I was just curious today and decided to see if my laptop monitor was able to support any other refresh rates besides 63. I began adding modes from 70 to 150 and each refresh rate worked which was suprisingly strange to because I know that LCD's aren't even able to go up to refresh rates that high. Changing the refresh rates didn't real seem like it affected the monitor because I know for a fact that the mouse becomes a bit faster and smoother with higher refresh rates. Is there someway of finding out whether or not the refresh rates are actually working on this laptop? OH! Also, when my laptop first starts up, the mouse is incredibly faster at the login screen. Right after I login, my mouse slows back down to the default speed. So...I have a feeling that the refresh may? be working just not when I'm logged in...

    "Refresh rate is the rate at which the electronics in the monitor addresses (updates) the brightness of the pixels on the screen (typically 60 to 75Hz). For each pixel, an LCD monitor maintains a constant light output from one addressing cycle to the next (sometimes referred to as 'sample-and-hold'), so the display has no refresh-dependent flicker. There should be no need to set a high refresh rate to avoid flicker on an LCD." See this.

    Exactly refresh rates have no effect on LCD. The response time of the LCD is still slower than even 60Hz.

    The mouse speeding up and slowing down is mouse drivers kicking in. At start up defaults are loaded, then when your windows logs in, it uses your preset settings. Same thing happens here and I never played arround with the refresh rate settings.
