My laptop won't connect to my TV anymore

[glma_engine]

Just recently my TV won't recognize my computer anymore. I have an HP laptop with Windows Vista and an LG TV. When I connect them my TV says it's connecting and then it says no signal. It was working just the other day. The only thing that has changed is that I loaded Clear Connection on my computer for internet, but I don't see how that would change anything on my computer. Any suggestions would be greatly appreciated.

I had this problem and after wasting close to an hour on this forum I finally found an answer by myself. Here's what you do:

Go into Device Manager

Display adater

Double click on your graphics card

You should see an option that says ROLL BACK DRIVER

Click that.

(Don't freak out if your resolution gets messed. )

Now just update the driver

Hope this helped!!

I had the same problem with my laptop to my Sony Bravia. After determining that the HDMI cable was OK I turned on my TV, then unplugged it, hoping that would work as a reboot of the tv's system, Lo and behold, it worked! Give it a try....

I had the same issue with my PC lapper and my Sony Bravia, and after determining that the HDMI cable and laptop output was ok on another TV, I turned on the Bravia, then unplugged it, hoping that would work as a de facto reboot and, lo and behold, it worked! Give it a try.

How were you connecting the Laptop to the TV? (HDMI, VGA, LAN, etc)

I have a Sony vaio and it use to connect via hdmi now my tv doesn't recognize it doesn't even try to connect, what's wrong?

I have a same problem, tried all you mentioned here and still no signal on my LG TV.
It seems to me like this connection was interupted when I installed win 8.1 on my PC, but I cannot belive in that theory and still looking for solution on forums.
I cannot recall if this problem firstly occured when I installed new OS win 8.1 or not so I am not sure but 3-4 years before it worked properly.
I have no device problems, tried to extend and duplicate displays (at nvidia control panel and screen resolution manu), windows key+p.
But every time when I connect or disconnect HDMI to TV PC makes a sound like something is connected or disconected, and when HDMI cable is connected on TV I can see HDMI ikon like it could be chosen, but when cable is disconnected HDMI cable icon is gray and couldnt be chosen.
Also in menu adjust screen resolution when PC and TV are conected both displays are recognizable but why TV says "no signal" and how to see anything on TV as I have on PC monitor I realy do not have solution.
Sorry for my bad english, but I hope someone has any idea hove to solve this issu.

Thanks in advance

I had the exact same problem. While the laptop is connected to the tv, turn your tv off wait a few seconds then turn it back on

Had the exact same problem. Follow these steps to resolve it.
1. Right click on your laptop main page and click Personalize
2. Click Display Settings and then Advanced Settings
3. Click on the graphics card tab at the top. It should be above the Adapter, Monitor, Troubleshoot, and Color Management tabs
4. Then click Graphics Properties, Multiple Displays
5. From the Operating mode section select Clone Displays then click Apply

This should fix your problem

I just had this problem today! Go to the bottom left where the microsoft symbol is, right click, and open up Device Manager. From there, double click display adapters, then right click Intel Graphics. Then click update driver software. Then browse my computer, then let me pick, then select the software from 2012. It worked for me! Good luck!
