Slideshow for Plasma Display

I'm throwing some pictures together to be shown on a plasma display and was wondering what the best crop and display settings would be to look best on it.

The display is a 480p 16X9 Panasonic. The technical page shows that its resolution is 852X480.

Does this mean that if I crop the shots to 16X9 and set the laptop external display to 852x480, it will look the best?

Any pointers would be greatly appreciated.
