Q: Keynote presentation set up for an Apple TV

I am setting up a presentation that will auto play and loop on an Apple TV. I am thinking of using Keynote to do that but am not sure if this is my best application. I need a very high resolution outcome as it is for a real estate community with beautiful views that need to really POP on screen. I am confused on the scale to use. I have the document set up as a 1920x1080 HD and the images the same. Once I complete all of the pages, I will import it from my desktop to my iPad Pro and then stream that to my Apple TV. Am I heading in the right direction here? Any tips and tricks to get a really crisp HD output would be greatly appreciated.

    Find out the resolution of the display that will be used, then in Keynote set up the slide size at the same resolution in:

    Inspector > Document > Document > Slide Size

    Brand new HD LCD LED TV's I know the aspect ratio, but was curious if it makes a difference if I create the background images in higher DPI. 72 vs 300 for example. Will that reflect in the screen view?

    I know the aspect ratio,

    To be clear about termiology:

     

    The aspect ratio is a proportion showing the width against height e.g.  4 x 3, it does not measure resolution.

    When using Keynote the aspect ratio is of little use in creating Keynote presentations, it only tells us if the presentation is set to widescreen or or not.

     

    What is important in creating Keynote presentations is the number of pixels in width and the number of pixels in height e.g. 1920 x 1080

     

    if I create the background images in higher DPI. 72 vs 300 for example.

    The term dpi means "dots per inch", it is only used when printing to physical media such as paper or film,

    dpi is of no use when specifying the resolution of Keynote, televisions and computer displays.

     

    The only setting available in Keynote to set resolution is,  pixels.   Therefore, keep to the accepted workflow of matching the slide size in Keynote to the end product (a computer display or television).

     

     

    When importing graphic files into Keynote, there is no point in using images larger than the pixel count set in the slide size:

    e.g. if a 2400 x 1600 pixel image is placed in a 1200 x 800 pixel Keynote presentation, 50% to the images pixels will be thrown away as the can't be resolved by the software. So as a rough guide, use images with the same size as the Keynote slide size.    Smaller images on the slide can be used in proportion if convenient.
