Look for an extender.  Look at specs too to make sure the resolution you 
want
to run is supported by the extender.

The length of a straight cable run for VGA is limited by resolution.  
You'll need
to invest in QUALITY cables though.  If not,  you'll experience ghosting 
on the
LCD or monitor due to impedance issues.
