ATV4k - how to share files from Windows 10

Hi there,

I have downloaded Infuse 5 to my Apple TV 4k.

I am finding it really difficult to figure out how the passwords work - when setting up share, between ATV & Windows 10 - I keep getting user name/password don’t match.

Do you also know if the 1080p files I am looking to share on ATV4k - when working, will display in 4K??

Can anyone help me please.

Tony
