Up to what resolution does your monitor support?  

Apparently it only supports up to 1024 x 768

Change these according to your monitor's specs.

And also verify that your monitor supports up to 24 or
even 32 bits.

If it does then change the DefaultDepth to 24 and in
the modes section add 1280 x 1024 and try it again. 

You might have to shutdown the machine and/or restart
it for the changes to take effect.
