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.

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

Clear Connection wouldn't create issues for the TV. Try reseating the HDMI cable first and see if that will bring the connection back. HDMI cables can be finicky, and moving the laptop could have jostled the cable.

I tried to put it into the other port on my TV and I unplugged it on my computer numerous times to see if that would help...no luck

Do you have another HDMI cable to try? I know some laptops require the TV to be plugged in, and tuned to the proper HDMI port prior to booting....you can try that.

I have the TV tuned to the right port. I haven't changed anything from the last time I got it to work. I know the cable works because I used it on another TV. It's like the signal gets interrupted or something because my TV will act like it's about to connect and then it doesn't.

I also looked at a forum for HP and someone else had my same issue but it didn't have an answer either. Here is what they had, I think they explain it a little better.

"when i have the cord plugged into my computer and my tv and i select duplicate the screen turns black then comes back up with the tv still responding no signal"

That is what keeps happening with mine. My laptop screen will go black like it usually does before it connects and meanwhile my TV says connecting. Then my laptop screen comes back on and my TV says no signal.

Check your Device Manager to see if any hardware items have issues (yellow exclamation point). I am wondering if the installation of your Clear Connection created an issue with the drivers. While not probable, it is possible....

I have same problem with a view sonic TV and a Dell computer!! I also want to watch movies!! I have another hdmi cable that turns into a mini hdmi for smartphones aa well as a usb? Should this cable work with computer? ( the hdmi to hdmi cable isn't working anymore with my dvd player as it used to either.) That's why I was thinking it was cord, but if the hdmi to USB cord should work with computer, then it's not that simple. Do I need to change the settings on my computer to recognize the hdmi to USB cord? So I can try to hook up the computer that way? Windows 8. ( I am new to windows 8 and hate it!!)

I'm having thew same exact problem. I have a custom built laptop, and a Samsung Smart 3D TV. Ive been using the same 25Ft HDMI Cable for over a year. Just stopped working randomly and I never moved the laptop or changed it's position. I use an Ausus Monitor as my Laptop screen and my desktop Asus screen works fine with all my HDMI cables, only the TV to Laptop Connection reads "No Signal" Ive tried on 3 different HDMI cables. all the same response. While my PS3 works on all the HDMI cables in every port of the TV. So it's the connection between my Windows 8 Laptop that worked for over a year and randomly stopped. I have not installed any programs or made any changes to my laptop. Just stopped working cold Turkey

Mate I had the same problem my Dell laptop would not display external monitors. I then when into control panel system and maintenance and into check drivers. Click on display drivers double click and it should tell you if your driver is working properly. My one said it wasn't working properly. So I clicked on the option below to reinstall display driver and windows dud thhs automatically and solved the problem!

If you have Nvidia go to the nvidia control panel and press the windows key and p at the same time until you get a extend screen the go to set up multiple screen set up and then you'll see laptop display and your TV (whatever it is) and un check your laptop and wait until the 15 sec begin and close the lid and see if it works. It did for me and click apply if it did. Hope this help you all.

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 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 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!

Yeah, unplug your TV and it should fix things. A port of mine stopped connecting to my laptop but the other port worked fine. No PC setting changes were helping but just unplugging the TV seemed to reset it somehow and it works perfectly as before on both ports

Always good to know Im not alone :) 
I have an Acer laptop and connect to a HD TV with HDMI cable. Its been working fine for over a year, even after upgrading to Windows 10.
What I get thats not mentioned here is when the PC is powering up my TV will show the same image as the laptop (the Windows 10 window with the circle of dots underneath) but on my TV screen the image is distored, ie its a blue background (laptop black) and has lots of black lines across the screen like its not tuned in right.

Ive gone into drivers for my onboard graphics card and it says its up to date.
The weird thing is, if I go into sound settings the Playback thats normally auto enabled when HDMI is connected - ATI HDMI OUTPUT- to my laptop is showing as not plugged in.
Yet if I go into Control Panel - Display- it shows SAMSUNG (my TV) as the 2nd option and when I disconnect the HDMI from my laptop it makes the disconnect sound, yet still it says under sound settings its unplugged and the tv stays a black screen after the initial blue distorted loading screen.
It must be an update to Windows or something as its happened in the last fw weeks and Im not aware of anything else thats been updated.

Ive tried unplugging both laptop and TV and plugging back in again but I still get the same result.
Ive tried updating Graphics card driver and Ive tried a different HDMI cable too.

Did anyone find a solution to this?

I rolled back to Windows 7 as Ive found out my laptops graphics card isnt supported on windows 10, so I thought that would be the problem.
But even on Windows 7 its the identical issue.

http://vid271.photobucket.com/albums/jj153/roninxena/VI...

this is a link to a video of whats happening on start up, the TV is showing the laptop image but its got a blue background instead of black and it only last until the laptop asks for User login id, then the TV shows No Source, but it stays highlighted in the Source list as if its connected to something that is actually on ( my ps4 is in the other HDMI and it only lights that Source up when the PS4 is actually on) on windows display settings it shows my Samsung TV as detected as second monitor too.

Have tried changing cables, switching off and unplugging, changing HDMI sockets and tested the HDMI connection on my laptop on a monitor screen to confirm its okay, Ive now tried rolling back to W7 and its still the same issue :(

I had the same problem. My connection from my computer to my tv via a HDMI cord was fine one day, now my tv says theirs no signal/source. Couldn't get it to do exactly what I wanted but I least got it to transfer the view to my tv.

just right clicked my desktop screen

clicked Graphic Options

clicked output to...

selected digital television.

I don't have the computer screen and the television screen anymore but at least it shows up on the tv a quick fix for an impatient person like myself.

Yes Ive tried that too thanks, it does show my Samsung as a 2nd monitor but nothing comes up on TV :( 
You could try holding the windows button and pressing P, if you havent already Christina, it normally brings up 4 options for Projection.

I had the same issue, so I studied the LG TV guide and discovered that you must get a top quality HDMI cable of the specifications cited in the TV's owner's manual, once I went and got the best cable at Best Buy that I could it worked like a champ. I was tearing my hair out and updated drivers and the rest of it until I just bought a top quality cable, with the premium cable everything worked great and my computer recognized the computer right away. I am running Windows 10 and followed the TV's owner's manual step by step and it worked!
