How to use a smart TV as a monitor via built-in Wi-Fi adapter?

After two years, I have just succeeded to do that in Windows 10. Assuming you have all required hardware:

  1. First be sure the TV source is switched to Screen Mirroring (each manufacturer may use a particular term for that.)
  2. Also make sure the TV is listed among other devices in Devices and Printers windows.
  3. Press windows+k keys and select your TV from list.
  4. Now your monitors will act as a regular secondary HDMI monitor.
  5. You may need to repeat this steps to succeed.

Your laptop or mobile device should support Intel's WiDi (Wireless Display) and have a WiDi receiver, or you can purchase a WiDi adapter separately. It will be something like this (NETGEAR Push2TV HD-TV Adapter for Intel Wireless Display PTV2000-100NAS HDMI Interface) but I am not recommending any particular such device.

Since I see that Samsung made a deal in June 2013 to start including WiDi in their TVs, it's unlikely that your current Samsung TV has this capability.

Intel's information on WiDi is here, and you can look up adapters from that page or from on-line electronics companies; there are several manufacturers.

The type of Wi-fi built into your TV is for networking, i.e. access to media from other devices. That is not the same as sending display content to use it as a monitor. It's like asking how to open a can by using an egg-beater - the Wifi you have, despite having the word "wireless" in it, is not the same as WiDi which is used for displays.

I hope that some salesperson didn't tell you that this would work, because without WiDi, all you can do is display media on the TV from other connected devices, but not use it as a second monitor.

Your question is similar to the one posted here.

This will also depend on the computer having WiDi capability; you haven't specified that, and only some have it (my Sony VAIO laptop has it included, but is advertised as such).


  1. Find an old laptop with wifi.
  2. Connect the TV to it as a monitor.
  3. Use remote desktop program on the old laptop to view and control your remote computer.
