I am trying to use an additional monitor to show a different screen to that of my laptop so that I can use PowerShow for PowerPoint - Laptop to show slide sorter and other monitor to show Slideshow. But whatever I try it does not seem to recognise the PnP monitor as an additional screen but just as a duplicate of what is on my laptop
What do I have to do to configure my laptop properly?

try Fn key with F5 or F8. depends on your model of laptop.
Look for the screen symbol on one of the function keys and try pressing that once and wait several seconds to see the screen changing video. Then press again if not correct.
If nothing is appearing on the projector, then connect a lcd monitor on the laptop and try the function keys intil it works thyen swap the monitor for the projector, and start the input scan for the active video input.
It's likely that your screen is "fried" (faulty) ... try to connect your laptop to an external VGA monitor, and see if the screen shows up (on the external monitor) properly. You may have to toggle the output display (device) from computer screen to external monitor ..using Fn+F3.
If it displays on your external monitor properly, it means your laptop screen is no good. You can replace the laptop screen, or just continue to use the external monitor.
If it does the same (blurry & different color, etc.) on your external monitor, then, your video card/module on your laptop is bad. This usually happens less often.
I have encountered this same problem once in the office when i was trying to do the same thing.
The solution: *Assuming you have windows xp*
1) make sure the projector and the laptop are connected (FN+F8), do a right click anywhere in your desktop then go to settings by default Monitor 1 would be your Lattitude D620 and Monitor 2 should be your projector, to make sure of that click on the 'identify' it should show a 1 in your laptop and a 2 on the projector 2) now select monitor 2 and select 'use this device as my primary monitor' check mark, by doing this your videos should play in your monitor but they will be a blank/black screen on the laptop (basically we are reverting the order).
