PPT "Advanced Resolution Settings"

[JohnNearSyracuse]

I have read some of the posts about decreasing file sizes, and have
read some of the excellent links mentioned about how to decrease the
file size. It is complicated, but I am getting some of it. My Epson 74C
projector is "1033x768." Therefore I know that I need to set the
maximum resolution of JPG photos that take up the full screen to
1033x768. None of the posts mentions that this can be done in Apple's
IPhoto, but that is all I have to work with I believe on my Powerbook15
G4 ? (I do not have Microsoft photoshop or Adobe etc.) Anyway, I have
gone to PPT Preferences, and am at the "ADVANCED RESOLUTION SETTINGS."
The choice is to check a box for "DPI" or OR SIZE, to select a specific
resolution setting. Right now, mine is set at DPI 72. (I believe this
was installed in my PPT2004 for Mac, since I don't believe I adjusted
this.) I want to be sure that I set the Advanced Resolution Setting
field to that which will give me the best projection quality. (But I
don't want my file sizes to be too large to slow things up.) I see that
the "grayed out" field in the resolution setting is "720x540" pixels.
(I don't know why that was set at that.) PLease advise if I should make
the change here, and uncheck the DPI box, and check the SIZE box to
change the resolution. And, if so, should I change the resolution to
the same as my projector 1033x768? I also have this resolution in my
PowerBook Display setting. What does changing the SIZE setting in the
Advanced Resolution Setting field actually do? Does it effect the
overall file size of a presentation, or just the quality of projection?
I have a huge presentation, and am cautious about making changes I
don't know about. Thanks,
John

John,

Most projectors just "copy" what is displayed on your computer. Ideally you
want everything set to the same resolution. e.g 1024x768 or 800x600, so that
everything matches up.

Most LCD projectors have a 'native' resolution. i.e. 1024x768. That's
physically how many pixels they have.

If your computer / laptop / notebook also works at the same resolution
1024x768, then that's great. If it works at anything else, then the
projector is going to re-size your projected image to make it 1024x768,
which can result in a poor image quality.

If your presentation uses graphics that are also aimed at 1024x768 (if you
want something to fill the screen), then that's also great.

Perhaps some other people will chime in with the mac specific info.

TAJ,
Thanks for your reply.
Since my projector is 1024x768, and I set the displays on my Powerbook
G4 to the same, I presume I am safe to go into the Advanced Resolution
settings and change it to1024x768, rather than at the 72 DPI which it
is currently set at?

John,

I'm not a mac user. But from what you are telling me.....that sounds like
the best thing to do.
