Hi Alan,
The instructions below that I gave you for Making Slideshows is for your ATV 4 
1080p unit.

“In the ATV 4K The obvious change, of course, is the adoption of the 4K 
resolution. Whereas the fourth-generation Apple TV maxed out at 1080p video at 
60 frames per second, the new 4K model supports a resolution of 3,840 x 2,160. 
This means you’ll get much crisper and smoother video than previously, assuming 
you have a 4K television.”

Kind Regards,
Ronni
