Serviio

Hi
I have a Sony KD75XH9505 and a Samsung S21.
I can't seem to figure out how to screen cast videos/pictures from my phone. Do I need to install any apps on the TV or phone?
Thanks.

This is a forum dedicated to DLNA and Serviio in particular. Casting from a phone to a tv doesn’t use DLNA, so this isn’t the best place to look for assistance. Since you’re using an Android phone and a tv running Android tv, there should be no issues.
