I have a Lenovo z580 Laptop (can give detailed spec if needed) and an LG HD TV. Laptop is running Windows 8

I have had the laptop connected to the TV via HDMI for a few months now. Not all the time but would connect to watch Netflix, play games etc.

Last night I tried to set up my girlfriends laptop so that it could also connect to the TV via HDMI. I switched the output to duel screen in the control panel and the TV went from "No Signal" to static. I tried to work out why this was happening but couldn't.

I connected my laptop to the TV to check it would still connect as usual but found that the same thing was happening. The laptop was connected but I was only getting static.

Tested the cable on my ps3 and it was working fine as was the HDMI port on the TV. Tried the laptop in a different HDMI port on the TV and had the same problem of just static on the screen.

Unfortunately I don't have another TV to test the laptop on.

Have tried to adjust the frequency, which was set at 59Hz, to 60Hz but it didn't make a difference. Tried rebooting laptop. Connecting first then turning the laptop on.

Very confused by this because it has been working fine for months then suddenly it stopped. Possibly it could be due to a Windows update? The last time I had the laptop connected and working well was about 2 weeks ago. During this time my laptop installed a Windows update. I think this is the only thing that has changed. Is anyone else having similar problems after a windows 8 update in the last few weeks?

Any suggestions would be greatly appreciated.

Yes I have tried with the other cables I have and they produce the same result. I also tested the cable on my ps3 and it worked fine with that.

I have exactly the same problem, I assumed it was my laptop at first until my friend brought his round and the same thing occurred.

Mine does work on other TVs though and the TV that's effected is an LG so I think that must be the cause although I still haven't been able to solve the problem.

My laptop is only windows 7 as well so maybe it was a blanket update for all windows systems that caused the issue?

I realise that this isn't that much help but nothing I have tried has had any effect.

I've just realised that one of the other TVs that I've tried is an LG. I have recently bought a PS4 though and so maybe that might be the cause, as you said that you have a PS3. Although that still works fine.

Could be a number of different things I suppose, the link between playstations and LG TVs seems strange though. Probably just a coincidence i'm sure.

Any thanks to / kovo39@seznam.cz

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

Try connecting the HDMI cable to diiferent HDMI slot in the LG tv. LG has HDMI(ARC), HDMI(MHL), HDMI(normal). MHL and ARC might have problems. The HDMI slots will be named accordingly in the tv

I think the problem is Intel HD graphics. I got a service call for an hp Pavilion desktop that was hooked to a Panasonic TV via HDMI and it worked fine for a long time. It's running Win 8.1 w/ Intel HD graphics. I brought an extra monitor and my Acer lappy to help troubleshoot the problem. My lappy is Win 8 w/ Intel HD graphics and it is giving me the same "No signal" error as the TV! Both the desktop and the lappy connect fine to the additional monitor via HDMI, but neither will connect to the TV. I'm attempting to download newer video drivers to see if this helps. If I find a solution, I'll post it here.

No luck w/ disable/enable video driver here. Windows 8/10 HDMI out to A/V receiver/big screen TV worked since 2012.
Last week it stopped, wasted hours rechecking and finally did System Restore to week before Windows 10 last update returned to service. I understand windows 10 forces updates so today HDMI returned to "no service". Went back and tried all the compatible drivers in Device MGR/video adapters/ Choose from list of compatibles... no luck. :?
Did 2nd System Restorejust now again, 1st time no go but read that if press Windows key + P and set to extend [not duplicate] it worked.
I switched back to duplicate and it's all working again, WTF?? Oh well, oh hell. We'll see how long it lasts this time.
Thanks MS 10.....:ange:

Hi

I have Lenovo laptop with Samsung tv connected to HDMI port. Experienced the same problem ('check cable' message) after Windows update today.
Many thanks to tips on this page - I went through following steps:
>Device Manager >Display Adaptors >Intel HDMI Graphics
Selected [Rollback driver]
Then went back in and ran [Update driver] and selected Automatically detect driver software and allowed it to update

This worked for me, hope it helps others.

I connected my pc to t.v. via HDMI cable. But also added device on pc in Control Panel. Tried to watch Netflix as well. But after 15 - 20 minutes Netflix went out and kept getting error message, "Your device may not be connected to the internet." Try again or contact your provider. This happened several times. Dish Tech Support was no help. They advised me to call Netflix. Now today i am going to try using a VGA Cable instead and see what happens. Sometimes people say you can do certain things doing this or that. But remember we are probably using different devices. And how long ago did this work for them? Is the information up to date? All we do is try and hope for the best. Good luck. If i were you, you can order a VGA CABLE from Amazon, they are way cheaper. But make sure your laptop and t.v. and t.v. have those inputs to use them before you spend the money.

What i did was plug a VGA cable from t.v. to computer. Turn off cable box, you won't need. Then turn on t.v. Turn on computer, go to settings or maybe your t.v. has a setting that says " PC, select that and your computer should work now on your t.v. screen. Doesn't matter what computer you have, it should work with the VGA CABLES.
