Windows 10: When I plug tv into laptop via HDMI I get sound and vision on tv but laptop screen goes black

Every thing was perfect until oneday I had picture but no sound I fiddled with something cant remember what then I had picture and sound on tv but laptop screen was black

:)

 

Laptop monitor is black but HDMI to TV works

So, I seem to be having the opposite problem of most. After updating my laptop to windows 10 the laptop monitor basically does not work - it's as if the graphics card does not see it. When I turn the computer on it shows me the dell logo with options to
open the boot settings, and it starts to show the graphics for loading windows and then just goes to a black screen. Like others I thought maybe it's the issue with thinking there's 2 monitors when there really are not because it's acting like my dual monitor
work computer at start-up, but none of the listed fixes worked. I tried to plug the computer into the TV via an HDMI cable and that does work but the laptop monitor goes from a 'light' black to an 'off' black. Of course the computer at that point only thinks
there's one monitor which is the TV when I go into the settings. I've tried every combination of plugging in and pulling out the HDMI at different points in the reboot process but I always end up in the same place of having to plug the laptop into the TV to
use it. It's as if the Intel graphics doesn't see the laptop monitor as an option. I also tried to update the graphics drivers but it says there are no available updates. Anyone else have this problem and a suggested solution so I can move my laptop away
from the TV?!

 

Split screen with sound on Laptop and TV through HDMI

HEY WILFREDO, you say this:

We show you an example, keep in mind that depending on your operating system and sound card, the images may vary, but the steps are very similar.

WHERE IS THE EXAMPLE ????????

The HDMI audio there in settings is already enabled by default as I have seen on all PC's I connected to TV's via HDMI.

You must not read the question.

They state that they already have SOUND out of the TV through HDMI or speakers on laptop for the video on TV.

Such as playing a Video on a media player/web page on TV via HDMI, there is sound.

And then playing another video on another media player/web page on the main laptop screen and they have no sound, as they should if I am not mistaken. But possibly not. Kind of like plugging in USB speakers, now your other speakers do not work as you have
to switch to USB as default speakers.

I get sound from every program no matter how many monitors are connected and what is playing what per display.

But probably this Laptop, you are going to get sound from both at one time on speakers or sound with HDMI on TV and possibly not on laptop. The HDMI sound enabled for TV could disable the sound for laptop speakers.

I am going to bed. I have 3 monitors and 1 TV connected HDMI to my PC. I will double check tomorrow, But I have a PC with Vinyl-VIA HD AUDIO and 5.1 surround sound speakers and not a limited laptop. There are many possibilities depending on your hardware
of video and audio and then configurations.

OP, is the sound coming out of the TV or the Laptop speakers while playing the video on the TV. Give me that info and i will check tomorrow. Because I know for a fact you can drag a video to the TV and have sound out of the PC speakers connected
HDMI and another video playing on PC and have sound for that too. But who watches 2 programs with 2 sounds going.

So I have never tried getting sound out of TV speakers via HDMI and sound out of PC speakers for a 2nd video playing the same time on PC.

 

laptop to tv with hdmi problem

Hi,

To begin with, I'm using windows 10.

I've had an HDMI cable hooked up from my laptop to my TV and easily duplicated the screen via the display settings to do so.

The other day, I removed the HDMI from the laptop.

The following day, I plugged the HDMI back into the laptop, made sure the settings were still set, but the image would not duplicate onto the TV at all. I scrolled through different options (such as duplicating, expanding, showing on laptop screen only and
showing on TV screen only) and nothing seemed to bring the image up on the TV.

I've changed the cable to see if it was a faulty cable, I've changed to different HDMI ports on the TV and I've plugged in other devices, such as my PlayStation to see if the TV picks up other HDMI, and it does.

The TV definitely registers that there is something there, the screen is black but never indicates 'no signal'. That only happens when I remove the HDMI from the laptop.

Thanks in advance for your help.

Cheers

Joe
