Its that time of year when Todd begins asking question pre sympsoia
events ;^) We have the new Dell Inspiron XPS laptops. Man these are
beasts - like small desktops. They come from the factory set to some
unreal resolution (1600x a zillion or something) ;^)

For powerpoint presentation heading to an LCD projector, do I need to
set this back to 1024x768 or can I run at default?

As always, many thanks!
 
I'd probably want to match the resolution to the projector--so, since your
projectors probably do 1024x768, that's what I'd set the monitor to as well.
But I wouldn't worry about it too much until it's time for the actual show.

I'm only on the other side of West Campus, Todd. Send one over and I'll give
it a thorough testing and get back to you within the year.

If you need to use 'em before you're in the neighborhood, I'd set them back to
whatever resolution your projector maxes out at. If the native LCD rez of the
laptops is really 1600 by gazillion (and it may well be) then the laptop
display may look a bit fuzzy; the projected image should be fine.
 
Thanks everyone! It was that later point Steve mentioned that worried
me: the fact that the laptop display might appear fuzzy. As long tas
the projector displays fine no worries.

But now Im further curious. If the laptop display is fuzzy, why
wouldnt the projection from that laptop not also be fuzzy? Is the
video output different from what is actually displayed on the laptop
screen?

LCDs have what you might call a "native resolution". Just one of 'em, unlike CRTs,
which can adjust their scanning frequency and other technomumbojumbaloids on the fly.

If you feed the LCD a video signal that's lower/higher than its native rez, something's
got to convert the input pixels to LCD pixels, so the image gets resized, effectively.

Send the same number of input pixels to an LCD running at matched resolution (ie, send
1024x768 to your 1024x768 projector) and no resizing's necessary.
