Monitor Resolution

[Brian Blater]

I recently purchased an Acer X223W 22" monitor. The monitor looks and
works great with my MAC or Windows, but for the life of me I can not
get it to function at full resolution (1680x1050) with linux. I'm
running Kubuntu Ibex with an Nvidia 8600 GTS card and using the Nvidia
180.29 driver. I'm not a real xorg guru, but I at least have an idea
of what things do what, but I just can't get this setup to run at full
res - I get 1024x768.

Can anyone give me some help getting this configured correctly to use
the 1680x1050 resolution?

Thanks for your help.
