PC laptops typically rotate through 3 different viewing modes when
connected to an external display (whether that display is another
monitor or a digital projector).
The modes are
1) laptop display only
2) external display only {ie: digital projector}
3) dual display of both laptop and external display
If you are showing a video clip, the video will only show on whatever is
set as the primary display - usually that is the laptop. For the video
to show through the digital projector, you must change the primary
display to the external monitor - if you don't do this, you will only
see a black box for the video. Note that using the digital projector
for the primary display will mean you have no display on the laptop
during the video and will have play close attention to the digital
projector image.
Different laptops have different ways to change the display modes -
usually through both the advanced display settings in the control panel
or using Fn plus another key. I prefer the Fn key combinations because
it is quicker. Look for the LCD/CRT key or it may be marked by a double
box (box inside a box)/single box key. On our Gateways, the key
combination is Fn+F4 and on our PC Tablets it is Fn+F3 and on our ACERs
it is Fn+F5.
Pressing the Fn key and the dual display key will toggle you through
these 3 modes so you can quickly adjust for different needs.
Hope this helps.

The image on the wall won't show a CDRom that is playing (we can see) on
the laptop. The laptop is a Gateway.
Thanks for all your help so far - we are stumped!

We have a teacher that has hooked up her laptop computer to an InFocus
projector. The image on the wall will only project the wall paper on
her desktop - none of the icons, no files, nothing. We can see the
mouse when it is moved, but that is it.
It has been shutdown, restarted, unplugged & replugged.
I've never seen anything like this! Do you have any ideas?
