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
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.
