I would like to show the screen of my Ubuntu laptop on a Samsung TV.

The TV has a menu entry called "mirror screen".

But up to now I found no way to get it working.

I need a wireless way to us the TV as monitor.

Any hints?

Exact hardware version: Samsung SmartTV UE55J6250

If it is not possible via software am willing to buy some hardware.

  • On a friend's LG TV a similarly named option is actually for Miracast. You might want to check if that's the case in your TV and clarify accordingly. – muru Mar 19 '18 at 10:04
  • Buy a Chromecast, open Chrome, from the menu choose "Cast...", select "Cast desktop" and select your Chromecast. – Jos Mar 19 '18 at 10:06
  • @Jos That means ignoring the TV's built in chrome cast like feature or potentially adding a second chrome cast via dongle if the TV has chrome cast built in. – WinEunuuchs2Unix Mar 19 '18 at 10:39
  • What Samsung TV model number do you have? – WinEunuuchs2Unix Mar 19 '18 at 10:39
  • It might be limited to Samsung phones and tablets but more goggling is required: samsung.com/uk/support/tv-audio-video/… – WinEunuuchs2Unix Mar 19 '18 at 12:17

Google Chromecast is likely the best and cheapest option for mirroring your Ubuntu desktop to your TV. Here is a short youtube video.

For setting up in Ubuntu 16.04 there are other users to help out if you have a problem: Google cast on Ubuntu 16.04

Note there is a now a version 2, an ultra option and even an Ethernet option.

The cost (without options) is reasonable around $35 USD.

Although this is the recommended option for the OP, check your TV model first before buying a Google Chromecast. It could very well be your TV already has it built in. Also check your blu-ray player as some of them have Google Chromecast already built in too.

  • @guettli AFAIK this will "only" allow you to cast the contents of Google Chrome. If you want to stream videos, you might want to give UPNP/DNLA a try. No additional hardware needed ! – Robert Riedl Apr 10 '18 at 7:13
  • "Google Cast" extension no longer exist in the Chrome Web Store: This extension has been discontinued. Learn more What is the new/alternative solution? – Sun Bear Oct 17 '18 at 3:30
  • Thanks for updating your answer. The Cast button works but I got the "No Cast destinations found. Need help?" message. According to Step 3 in ChromeCast Help, it states It is compatible with both 2.4 GHz WiFi 802.11 b/g/n WiFi networks and 5 GHz networks. If the SmartTV and Ubuntu 16.04 Workstation is connected to the network via LAN (not wifi), can ChromeCast still work? The Workstation is able to ping the Samsung SmartTV. I am able to ChromeCast to the SmartTV using a mobile phone. – Sun Bear Oct 17 '18 at 10:51
  • @SunBear We need to thank Pablo for the edit. The concept of Chromecast is wireless connections. For wired connection HDMI is the preference and I use a 25 foot cable to laptop. There probably are Ethernet LAN broadcasting apps but I don't recall reading about any. – WinEunuuchs2Unix Oct 17 '18 at 10:58
  • @PabloBianchi Thank you for updating this answer. WinEunuuchs2Unix, I have tried using another Workstation that is connected to the network via wireless 5GHz to ChromeCast to the same SmartTV. However, I still get "No Cast destinations found. Need help?" message. What should I do next? – Sun Bear Oct 17 '18 at 11:42

This is my work-around, not a real solution.

The laptop gets connected to the TV via a short cable.

I use a wireless keyboard (inclusive touch-pad) to control the laptop.
