Why?  What is your exact problem?  Is the resolution too small?  Could
you be a little more specific about the problem?  What kind of laptop
is it?  What kind of connector does the external monitor use to
connect to the laptop?

Eduard:

Make sure your external monitor is connected and displaying (even badly).
Since you mention that you can read it, I will go on the premise that 
you are already there.
Then:
click the K Menu,
click "System Settings"
click ""monitor and display" under computer administration

Under the first tab "Size, Orientation, Positioning" be sure the slide 
bar near the bottom is set where you need it to be.  I think Kubuntu 
automatically assigns a default value that may or may not be correct. 
Check the refresh rate to the right of that also.  Your external monitor 
manual should have the value you will need, or it may be on the menu of 
the monitor itself. Don't change it unless you need to, it can make your 
display unreadable.
Then, select the "Hardware" tab near the top of the window that opens
from there, you should be able to select your monitor and go from that 
point.

Note that you may have to select the "Administrator Mode" button and 
enter your password in order to make any changes.

I have no idea if this will stay at the values you set, or if it will 
revert when you shut down and repower. It may be fine for an external 
monitor, but be unreadable for the internal monitor on your laptop.
All I can suggest is that you try it.
Good Luck,
