Laptop will not connect to TV via HDMI anymore. Only Static on Screen. Windows 8 Update Problem?

[jpt2]

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.

make sure the hdmi is plugged in
go to the device manager
under display manager
double click the graphic card
then go to driver and click disable
then click enabled
hopefully it worked because it worked for me

This display adapter solution worked for my Win10 Lenovo Thinkpad P70 w/ nvidia Quadro M4000M. The P70 occasionally just... stops feeding to HDMI, and restarting the PC does not help. I still don't know what causes the problem, but thank you for your response.

'Windows' key plus 'P' key brings up 'Project Screen' Options. Then make your choice ! Duplicate ??

update your intel graphics driver thats worked for me

Nope nothing is working. I connect via HDMI and it doesnt show up just black screen. I remove it and says no signal. I reconnect and says No signal. I disabled the Intel Graphics Driver and enabled it, and still nothing. I can connect wirelessly but not via HDMI. I tried changing project to Second screen and it reverts back to Laptop Display only. Nothing works and no solution has worked. It worked a few months ago but not now. And its definitely a Laptop problem with the HDMI. I connected to a external Monitor and it worked though so i dont know what to do. I Hate Microsoft and Windows now because they always break things.

Kowo 39. THANK YOU! 2 years later and you're still helping people. Worked perfectly, other than re-installing the driver made it unusable again, so just gonna keep the old driver for now. I want to hug you right now hahaha.
