Transfer screen via network?

Is it possible that I use my TV, which is connected to my router via a network cable, as a screen for my laptop which is also connected with a network cable?

That I can also reflect the things on my laptop on my TV from my office.

Simple: no.

The TV can't stream via network.

What you may be able to do, various TV channels are streaming via the Internet.

Of course this is not possible with all channels.

Maybe this software will help you:

Or you use a paid streaming service like Zattoo, or similar.

But I have no experience with that.

…

I just realize that I misunderstood you.

Maybe that works with devices like Chromecast, etc.

But I do not know that either.

Otherwise you could lay a long HDMI cable and go over the HDMI output of your notebook…

Try Joyn!

Some systems are LAN Miracast capable. It's possible that this will work.
