I was wondering if anyone knows how to split-screen with 2 screens using the Onkyo AV Reciever TX-NR636.

To specify, I am trying to split-screen with a Xbox One and a Wii.

The only option I know of for this is to use a video matrix box that takes more than one input and resizes to fit more than one input into a single output image.
Its usually used for having 4 different videos on one big tv so you can watch 4 different sports games at once for example
