Activate sound

[Dave Davison]

Just bought the appropriate cable to connect my laptop to a LG smart TV, instantly got the picture but no sound from the tv speakers, obviously some setting needs tweeking but the tv did not come with a manual. I did a search on line for the model [43UM7450PLA] but in the search result I could not see a section that dealt with my issue. Can anyone with such a tv talk me through the setting change please. My earphones are not plugged on. Dave

Dave, I didn't find an answer but I found a place where you can ask the question and perhaps get more information.

By cable you mean HDMI cable right? Change the laptop output sound setting to use HDMI instead of laptop speaker.

Revert back to laptop speaker when cable is disconnected from the smart tv.

Your smart TV may support wireless mirroring connection via Miracast or even Airplay for both video and audio.

You may be able to use/try chrome browser CAST function to mirror a chrome tab and even your desktop albeit with a bit of delay but serviceable.

Thanks guys, The link you mentioned Bob is the very one I found but is somewhat vague but the laptop setting that Jolas recommended does in fact mute the laptop speaker diverting the sound to the tv so problem solved, great result Thanks. Dave.
