How to use a SmartTV as second screen over wifi?

If we would like to use a SmartTV as a second screen over wifi using Linux, how could we do it? Is there a way to do this?

For my case I'm using a Samsung SmartTV and Ubuntu 14.04 LTS with KDE 4.

The TV automatically become a second screen if with we put an HDMI cable to it. And it is capable of sceen mirror too. But I don't know how to use it as a second screen over wifi.

If isn't a way using just the TV, are there devices that we can use to do this?

Solution 1:

I have never heard of a software project within the FOSS community to do this. There are plenty of commercial solutions available, you may perhaps Google linux HDMI over wifi, you will run into them.

Apart from this search, by the look of it, I especially liked an object called WIFI2HD2 HDMI® over Wi-Fi Adapter by StarTech.com because it does not have a transmitter on the pc, just a receiver attached to the TV. But I am not sure this works with Linux.

There are however other solutions: have you heard of CuboxTV? Nowadays, it comes pre-installed with Xmbc/Kodi, it is a full-fledged Linux pc (which means it can access your Samba shares, NAS, UPnP devices), you can ssh into it, it can be controlled with a smartphone app at no extra cost.
