Windows 10: hdmi not working

I am asking about this again because I never got a solution.

When I plug in the hdmi cable between my desktop PC and my big screen tv, things can get a little crazy. That means nothing will open full screen on the pc monitor. Therefore I can not immolate what is on the monitor to the big screen tv.

It has been suggested that I don't have the right drivers or no drivers at all for the hdmi.

Does anyone know how to update these drives?
Thank you.

Hdmi sound not working

Hi Peter,

One possible reason why the HDMI sound does not work is due to the conflicts with the playback settings. For us to help you make the HDMI sound to work, we suggest that you answer the following questions for further research:

• Have you made any recent changes to your computer?
• What is the current build and version of your Windows 10?
• Have you tried to download and install the most updated sound and display driver of your computer?

Meanwhile, we suggest that you perform the steps on this
article as our initial troubleshooting and see if there will be any changes on the HDMI sound.

We'll be waiting for your response.

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.
