You've got the laptop and external monitor set to mirrored.  Mirrored
means "Make both monitors look the same" so X has to select a resolution
that both monitors have in common.  LVDS1 supports 1280x800, 1024x768,
800x600, and 640x480.  VGA1 supports 1280x1024, 1024x768, 800x600,
640x480, and 720x400.  You can see only three resolutions are in common
and those are the three you are given as options.

Uncheck the 'mirrored' checkbox and arrange the monitors side by side or
one over the other, then you can use both at their maximum resolutions.
Or else turn your laptop monitor off when you're connected to the
external display.

Or, if you want something more exotic than gnome-display-properties
allows, you can do whatever you want using the xrandr command line tool.
For instance, you can set up viewports, scale or pan, and so on.
However these more advanced options are generally not what average users
are looking for, thus aren't supported in the GUI config tool's design.

Title:
  The resolution is stuck at 1024x768

Status in “gnome-control-center” package in Ubuntu:
  Invalid

Bug description:
  Binary package hint: gnome-control-center

  After upgrading from ubuntu 10.10 to 11.04 I can't change a monitor
  resolution greater than 1024x768 even if my video card and monitor
  support a higher resolution. Executing xrandr --output VGA1 1280x1024
  change the resolution correctly but unity launcher doesn't know that
  the resolution is changed so is not a good workaround.  ...perhaps the
  bug is only on gnome-display settings?

  $ lsb_release -rd
  Description:	Ubuntu 11.04
  Release:	11.04

  I have already reported this bug in
  https://bugs.launchpad.net/ubuntu/+bug/776719 but I don't know how to
  add ubuntu-bug generated report to an existent one. So I close the
  first and open a new one.

  Thank you very much
