    Is it safe for me to higher my laptops refresh rate from 60-75 or 100htz?

    It says it may damage the hardware, but what are the chances that it will?

    There's very little point in exceeding the default or the manual's recommendation. LCDs don't work like CRTs. There's no phosphor dots that glow only for a fraction of a second and need to be refreshed by a sweeping electron beam. Instead each pixel has its own transistor that keeps it on or off or in between until it's told to do otherwise. When it is asked to change, it takes a finite amount of time for it to switch from the old shade to the new one. On a good current TFT displays that switching time tends to be equivalent to about 50-60Hz. That's why there's still a bit of ghosting on an LCD display in high motion, high contrast graphics.

    the "refresh rate" is determined by the transistor latency of the TFT screen.

    TFT screens tend to be easier on the eyes anyway. (Apart from the effect you get with scrolling text on crap ones which really irks me)

    You don't really need to try to force your refresh rate higher, and will hit the natural limitations of the transistors if you do.
