AZ> AA> PP came up in conversation tonight with a pastor-friend. What exactly
is

the

AZ> CS> The output is taken from the video output (external monitor connector)

AZ> CS> projector.

AZ> CS> The projector becomes an external monitor for all practical purposes.

AZ> CS> Most modern projectors come with a remote that can be used to control

AZ>As far as actually projecting, there's not much difference between using
OO.org

AZ> There are a couple of slightly-tricky parts:

AZ>1) What happens when you plug in the projector to the laptop's external VGA
AZ>port varies with the laptop... in many cases, you'll need to restart the
AZ>laptop. In some cases, you need to go to the Display control panel and fuss
AZ>around with settings to enable the external 'monitor'... in other cases, you
AZ>may have to press a key combination-- often the laptop's FN key along with
one
AZ>of the F keys-- often it will have a rectangle icon on the key (to indicate
a
AZ>monitor)... you may have to press the proper key combination a couple of
times
AZ>to enable both the external device and the LCD panel at the same time.

Alan, I am having trouble using my laptop (XP home) with a
InFocus LitePro 580 LCD projector. I haven't been able to get a
simultaneous display on the projector and the laptop. Is there a
possibility that the projector is not compatible with XP? The 580 is
rather old. Further, the desktop image on the projected screen is chopped
off at  the bottom and I haven't been able to change the projector screen
size to prevent this.

AZ>2) It can takes several (3-5 minutes) for the projector to warm up before it
AZ>shows anything on screen... and if you don't know if the projector is
working
AZ>AND you're not sure if your laptop is set up to send signal through its VGA
AZ>port, it can be confusing!

AZ>3) If you're looking to purchase a projector, and it will be primarily used
for
AZ>PP (etc) presentations, you can save a couple of hundred dollars by buying
an
AZ>800x600 (SVGA) one rather than a 1024x768 (XGA) model... PP presentations
look
AZ>identical at either resolution.
