Need to mirror cast from screen to another.

[cu3ed]

Hey folks. Rather simple. I need to see about a second tv screen that shares the same picture in another room for my dad. Doesn’t matter it shares the same channel.
It’s a virgin box as source via hdmi, does anyone have any good preferably wireless solutions?

Many thanks.

I can't offer specific advice but just be aware there are potential content protection limitations that you may need to consider i.e. some casting devices will only display a black screen on the second display for protected video content, etc.
