Forcing a refresh rate on an E207FP

Question

I looked at the technical specs of the E207FP and noted that lower resolutions supported a refresh rate of 75Hz at low resolutions

VESA, 720 x 400 - 31.5 kHz Horizontal, 70.0 Hz Vertical, 28.3 MHz
VESA, 640 x 480 - 31.5 kHz Horizontal, 60.0 Hz Vertical, 25.2 MHz
VESA, 640 x 480 - 37.5 kHz Horizontal, 75.0 Hz Vertical, 31.5 MHz
VESA, 800 x 600 - 37.9 kHz Horizontal, 60.3 Hz Vertical, 49.5 MHz
VESA, 800 x 600 - 46.9 kHz Horizontal, 75.0 Hz Vertical, 49.5 MHz
VESA, 1024 x 768 - 48.4 kHz Horizontal, 60.0 Hz Vertical, 65.0 MHz
VESA, 1024 x 768 - 60.0 kHz Horizontal, 75.0 Hz Vertical, 78.8 MHz
VESA, 1152 x 864 - 67.5 kHz Horizontal, 75.0 Hz Vertical, 108 MHz
VESA, 1280 x 1024 - 64.0 kHz Horizontal, 60.0 Hz Vertical, 135 MHz
VESA, 1280 x 1024 - 80.0 kHz Horizontal, 75.0 Hz Vertical, 135 MHz
VESA, 1600 x 1200 - 75.0 kHz Horizontal, 60.0 Hz Vertical, 162 MHz
VESA, 1680 x 1050 - 65.0 kHz Horizontal, 60.0 Hz Vertical, 146.25 MHz

From my understanding, all TFT panels run at their native resolution(in this case 1680*1050) and just distort the input image to fit the displays output.

should I be able to force the monitor to run at 1680*1050 @ 75Hz without

A) damaging the unit(which I'd doubt since it would technically be running at that when set to 1280*1024 @75Hz)

B) invalidating the warranty.

I already know how to set it via my driver settings it's quit simple and I'd done it with several older low-binned CRTs to match their design specifications

Also, would flashing the monitors firmware invalidate any warranties? if I'm allowed to run it at it's optimal settings, I'd like to be able to flash ti so that I wouldn't have to bother manually forcing the refresh rate higher each time I change my monitor configuration(or have to reconfigure xserver in linux based OSes)

Why would you want to? I understand to need to run a CRT @ 75Hz to avoid flickering and eye strain, but, TFT monitors use completely different technology which produces excellent results at 60Hz.

Invalidate the warranty  ?  You bet it would   As farrellart stated, the optimal native 60 hz or what ever is shown on the User Guide for that LCD is more than good enough.  Its optimal for the LCD, and trying some thing fancy to change it, thinking it will give you the cats meow is foolish at best.   LCD's do not need to be refreshed like CRT's.  LCD's are always on.

that still doesn't smooth out the motion of my mouse wheni drag it accross the screen or makes y games look smoother... temped to use 1280*1024 despite the distortion...

How about the video card driver or mouse driver that you should look into for an answer to the smooth motion gitch.  Not the monitor

when i tried the monitor at 1280*1024, it wasn't jerky like it was at 60Hz though... some people are more sensative to changes in motion,and I'm one of them apparently.
