My Motorola G100 have a feature called Ready For that allows the phone not only to be mirrored to the TV but also a fully fledged desktop OS, very cool!
A picture of my TV with a split screen with Twitch and Lagrange.
(Sorry about this being a Google Drive link. Something is not working with the file upload from smol.pub)
The large screen allows me to use a very large font without messing too much with the layout and still space for other window if needed. Nice for a late night relax after work to take my head a little out of the computer.
I'm actually posting this using my cellphone Opera while connected to the TV. Not too bad!
