Resolution

[Stephen Durham]

Hello,
        I have been looking for an answer to this for a few days now
with no luck. I have an LG L1710B LCD and a GeForce 6600GT, currently my
resolution is 1280x1024 at 60Hz with a Horizontal Frequency of 63.9kHz.
According to LG the resolution can be 1280x1024 at 75Hz with a
Horizontal Frequency of 79.9kHz. I understand how to set frequency
ranges for a CRT monitor, but I am not sure how to specify exactly what
I want for a specific resolution. I don't want to just change it and
damage my monitor. I am using the drivers from the Nvidia website,
because support for the 6600GT didn't appear until the 6629 drivers, and
the ubuntu drivers only go up to 6110 (or something like that).
Thanks,
Stephen
