ROFL THE WORD PENIS IS HILARIOUS!
Just curious... I know it can display 60, but what's the maximum?
How Much Hz Does The Lcd Have?

You're pushing your luck little man
Most LCDs I've worked with have a set frequency rate of 60. That's all I know.

The CPU sets the LCD timings, and the LCD tries to keep up 
You can certainly run it at 100Hz. You can also run it at less than 60Hz, although if you go too high or too low, then the display will start to flicker and look odd.
One thing about high refresh rates is that the CPU has to read all of the LCD frame buffer memory every time it refreshes the LCD. This means that the higher you set the LCD refresh, the slower your program will run! (although it's not a very major slowdown).
I think the LCD tweaker program that's available around here can be used to try different LCD refresh rates, have a look at it if you're interested.

Lol, you dont need to adjust frequancy for that to happen sometimes!Robster posted on Feb 13 2006 at 10:44 AM said:

Running off FPLL (which is default), 30Hz is its slowest, 310Hz is its fastest.
Flickering is quite bad when slow, and taking it over 110Hz washes out the colours (black becomes about 75% gray at its fastest.)
You can't take it much higher as the LCD fails to read the sync signals, and you can only get lower by using the UPLL (which is roughly the half speed of FPLL)

My lcd on my pc runs
63.92khz horizontal and 59.96hz vertical. Is this normal, as it is supposed to be 60 for each?

59.96hz vertical is normal. you video card will sync to it anyway. (vsync)
horizontal is 1000 times faster, so it's a whole new can of worms.

your vertical resolution is probably about 1024, so you need to write 1024 horizontal lines in the time it takes to do one screen update. So no wonder the numbers differ by about this factor.
