presentation displayed on Widescreen

[Kurt Merkel]

My client is showing his presentation on a 40" widescreen TV (16:9
ratio). Do I have to create slides higher than 72 dpi to have the
picture sharp?... if so, what's a safe dpi, 100, 200, 300?

Thank you.

DPI and the size of the screen don't really matter in this case.

What you need to work out is the display resolution of the computer that'll be
running the show. Say it's 900 x 1600 pixels/dots. It won't be, but fill in
the correct numbers when you know them.

You'll want to set PPT's Slide size to something proportional to 16x9 (16 by 9
inches works for me and saves wear and tear on the calculator).

Images that will fill the screen should be the full screen resolution, again in
pixels. 1600 x 900 pixels in this example.

By using the sizes I've mentioned above, you can work out the needed image size
by drawing a rectangle in PPT then noting its size. Make the image that size
at 100dpi and you'll be good to go.

Depending on the image, you may find that they look a bit better if you go for
a slightly larger image and let PPT downsample a bit for display ... 120 or 150
dpi for example.

Thank you, Steve. This forum has been very helpful!! I don't use
powerpoint at all. This is my second project and it will now turn out
beautifully. Again, Thanks... Kurt

Hi

The dimensions I use for a wide screen powerpoint presentation are
25.4cm wide and 15.88cm high.
This will print on a sheet of A4 and is scaleable to any size 16.9
screen.
As for resolution, I use 120dpi as you get a nice crisp image and you
can print it at A3.
Also by using jpeg files, saved to level 6, it keeps the overall file
size down.

I hope this is useful.
