Stranges effects.

[Chris Watts]

I recently experienced two unexpected effects when giving some powerpoint
presentations that I wonder if anybody can explain.


First.
I have two presentations that contain embeded audio files - wav. When the
PPT is run and the files played through the computer's internal speakers all
is as expected. When I plug an external audio amplifier into the headphone
socket then one wav runs normally - the other runs about twice as fast.
Same computer.

Second
My computer (laptop) has a widescreen display. When I play the PPTs on the
internal monitor then the sides are clipped, as I would expect. When I plug
in a digital projector then projected display is at the correct aspect ratio
(and fills full screen, no clipping at the slides); the internal monitor now
shows an image stretched to full screen (wrong aspect ratio). I have
changed nothing but just plugged in the projector.

Can anybody explain these effects?

TIA
Chris

I'm not sure about the first, but the second is expected.

The monitor is a different aspect ratio than the projector (you knew this).
But the projector is given the priority for showing presentations, so the
desktop was told to use the projector dpi settings and fill the screen.
Because of the different aspect ratios, the monitor appears stretched and
the projector appears normal.
