Windows 10: HDMI issues

I hope you can help with this problem which is now unbelievably frustrating :-

After working fine for ages, my HDMI connection has given up the ghost. I have my laptop connected to an external TV using two HDMI posts and the appropriate cable. Suddenly, it stopped working.

Since then, I have:

• changed the cable but found out that this was not the problem.
• Tried connecting to a separate TV monitor and, therefore, ruled out a TV problem.
• Updated the operating system to Windows 10 2004.
• Deleted Radeon Vega Graphics 3 and reinstalled.
• Tried a power reset, disconnecting TV and computer for five minutes, and then reconnecting the TV first, followed by the laptop second.

Every time I press the Windows key+P it does not recognise the presence of an external monitor.

However, when I pull the HDMI cable out of the laptop port, the external monitor recognises that it is no longer connected to HDMI.

I have looked for updated drivers for the graphics card and the programme tells me that I have the best ones installed. It also says that the device is working perfectly.

Would you care to suggest an option I might not have considered yet, please?

Many thanks!

:)

I plug my HDMI cable into the card, then into my TV. Those are the steps that I have to do. All the steps you list make absolutely no sense to me.
