HDCP copy protection?

I have an MSI laptop that I've always connected to my TV with an HDMI cable without any problems. Now I've bought an LG TV, which recognizes the connected PC but doesn't display a picture. The TV's error message says there's a problem with the HDCP copy protection. What can I do?

The HDCP is a mess to keep the film industry in the mood. Here all data is kept encrypted into the TV. This ensures that the films cannot be recorded.

The system, however, constantly makes problems, for example, to read here with Microsoft

And look here:

At NVIDIA, you can’t turn it off (at AMD already). In the post it is also suggested that certain cheap HDMI splitters can’t do the HDCP and so TV and PC then assume that the opposite cannot do that and then work unencrypted. Only if there is a program or streaming service on HDCP will it not work, but everything else will be.
