Can I send/control my PC screen from another room/screen wirelessly?

Hi all. So this is totally out of my knowledge base. I have my PC hooked up to my home cinema in the living room. I was wondering if I can either send the picture to the bedroom tv or even better control the PC from the bed room as if it was in the same room as me. Mainly for movies (not those ones) but maybe for playing games too.

Is this even possible? If so what are my options?

Both my TVs are new modern ones so that should work! How often is a problem solved without spending money? lol Thank you.
