Ok the TV is an early digital one, but sound is not appearing through the TV speakers and the image only fills around the middle section of the screen. Was trying to watch something on BBCi, but ended up trying to hear it via the laptop speakers.
TV works fine from other sources including its own built in digi. PC is a Win10 with HDMI output. I tried all the picture and sound settings on the TV, could it be a setting on the laptop please?
There's lots of volume control options to play with - have you got something muted for the HDMI part?
Not that I could see in the TV settings..
It is an HDMI input on the TV and not DVI?
I meant in the laptop settings.
It may help to know:
make and model of laptop make and model of TV your browser whether you are extending the desktop or duplicating it
In the Windows 10 sound mixer applet you should see a HDMI slider channel. It might be disabled for some reason.
Make sure they are connected together before you boot up the PC. I have known it to make a difference. I have had similar problems with my Ubuntu laptop, now I know what to do, it's easy, but getting there was a journey. Good luck.
Its an LG TV around 47". The laptop is an HP Compaq CQ62 on Win10.
Clicking the speaker icon in the bottom RH corner bring up the sound mixer. Click System Sounds and I see Sound, with HDMI Device (not plugged in) and Speakers (my laptops soundcard).
Connect the HDMI lead and it recognises the LG and its properties. I can use the test button and it works via the L+R speakers of the TV fine. However, if I then play something from BBCi player, the sound only comes from the laptops speakers.
I think I am doing what is called duplicating the screen - what ever shows on my laptops screen, is shown on the TV too.
Is there a way to expand the picture to fill the entire TV screen?
Control Panel | Sound, then Playback tab
There will probably be more than one device listed (eg Speakers/headphones and HDMI Output) with one of them having a tick over it. Make a note of where the tick is, and then highlight HDMI and press Set Default.
If you play something (eg in Media Player) you should now find that the sound is coming out of the TV.
Change it back to the previous setting when you've finished.
That may be controlled by the TV. There may be an obscure setting to say (effectively) expand to fill screen.
However you could also try (on the PC) Control Panel | Display | Adjust resolution and select a slightly higher value in the Resolution drop-down or slider. Make a note of what it was originally before changing anything!
It is possible that if you set too high a value, the image will disappear from the laptop screen and the screen will go black. Fortunately there is a safeguard in Windows: you have to press a button "Accept this change" and if you do not press it within a few seconds (eg because you can't see it on the blank screen!) the resolution will automatically revert to its previous value.
Change it back to the previous setting when you've finished.
Let's try first the picture.
You want to "extend", not "duplicate". And you want to tell the laptop that the second monitor (ie your TC) has a resolution of . At present it is sending the TV what it shows on its own screen which is 1336 x 768 pixels. So that appears just in the middle of the TV.
If you press the Windows key + P you get a menu to extend. See eg the examples at
You may also then need to set the properties of the "second monitor" (ie TV). The link above gives an example of that too.
Don't forget to use Windows+P to come back to using just the laptop screen when you finish - else you'll find you mouse pointer vanishing off the edge.
As regards the sound, I'd expect you to have to use the audio manager to change the default for playback from speakers to HDMI but I've not had time to look up what that laptop uses.
Bugger. After "of" please insert the "1920x1080" I assume comes with a
47" LG
No, he probably means that the windows sound goes to the analog ports by default, and you need to tell it somehow to go to the HDMI ports instead/as well.
I know how to do this in Linux...
May need to set the HDMI rather than Speakers as default playback device (right click speaker icon in tray).
doesn't have HDMI, but the reason I checked is because my imac from 2009 could put video but not audio through to the HDMI port.
Model dependent? See eg
yes but not 4K until 2009 then only at 24Hz it seems, which could be why the picture appears small.
It has both HDMI and a multi card reader.
Err...I must have missed where 4k came into it - including when the BBC started streaming 4k
I never doubted it (the HDMI that is) :)
