Hey guys thanks for the help! I called HP support after coming up empty 
with online searchs. After an hour and a half and three technicians 
telling me they didn't support Linux and I'd invalidated my software 
warranty etc. they said the VertRefresh should be 60 and the HorizSync 
should be 63.925 for 1280x768 .

I also went to the link Markus provided and filled out the form getting 
the following:

------------------------------------------------------
Max Bandwidth: *350* Mhz
Max Vertical Frequency: *60* Hz
Max Horizontal Frequency: *63.925* Khz
Minimun Refresh Rate: *60* Hz Min Bandwidth: *20* Mhz ( anything more 
and I got a  RESOLUTION TOO HIGH error )
Min Horizontal Frequency: *30* Khz

ModeLine "name" dotclock width x x x heigth y y y #RefreshRate

ModeLine "1280x768" 83.77 1280 1336 1616 1728 768 770 782 808 #60Hz
--------------------------------------------------------

So I'm ready to give this a try but I'm a little concerned that I might 
damage something... this may be a dumb question but the wrong settings 
can't damage the LCD, can they?

Thanks again for your help guys!
