Windows 10: No signal on TV using HDMI since windows 11 update.

Since updating to windows 11 I have been unable to get a signal from my laptop to any HD TVs through HDMI. Everything works fine on monitors and the TVs I'm trying to connect to worked when windows 10 was installed on the laptop. I have made no hardware changes to the laptop and it has suffered no damage. I have tried:-Updating graphics drivers both integrated and dedicated-Used DDU to completely remove display drivers and reinstall-Hard reset after driver install-Updating chipset drivers-Updating bios-Different HDMI cables and ports-Checked windows display settings to ensure the correct out

Hdmi TV no signal

Thank you for the update and sorry for the delayed response. To isolate the issue, try connecting the cable to other ports or use a different HDMI cable and see if it will work. If not, try following these steps to check output settings and see if it will
resolve the issue:

• On your desktop, right-click on a blank space and select Personalize.
• Click System then select Display.
• Check if you can see the TV as second monitor.
• If not, click Windows key + P.
• Select Duplicate.
• If the duplicate option is not applicable, select Extend instead.
• After that, repeat steps 1 to 3 again and see if the TV is now detected.

Get back to us with so we can provide further assistance.

Loss of HDMI signal on a recent TV after the latest Windows updates.

I have a recent LG TV (under warranty) connected by HDMI to a recent computer under Windows 10. For its graphics part, the PC has an Intel HD Graphics 500 GPU.

For several months, the whole thing worked very well but since the last Windows updates, a PC restart causes a loss of HDMI signal. In general, disconnecting the HDMI cable and reconnecting it will restore the Windows screen.

First I called on the TV's after-sales service, which even changed the TV's motherboard without solving the problem. After many discussions with LG specialists, this would be due to the latest Windows updates. They explained to me that Windows must produce
an HDMI signal for a (recent) television set and not a signal for a monitor. On their advice, I tried to adjust the Windows settings by choosing TV instead of Monitor but this was not enough.

I also checked if the video driver could be updated, of course, but I always automatically find "Generic Plug & Play monitor driver".

Please provide me with a solution because PC restarts are very frequent after Windows updates and these updates seem to be the cause of the problem.

Thanks.
