Screen brightness can't be controlled + HDMI does not work (GTX 1050)?

For several weeks, the screen brightness on my laptop (MSI GL62M 7RDX - 64 bit) can no longer be controlled. In the energy-saving options no controller appears at all and on the keyboard as originally possible it does not work.

Furthermore, my HDMI connection is no longer synonymous, so I suspect some connection problem with my graphics card.

If I want to open in my NVIDIA control panel the message appears:

The NVIDIA display settings are not available.

You are currently not using an ad connected to a GPU from NVIDIA.

In Device Manager are two graphics cards:

- Intel HD Graphics 630 (+ yellow triangle with exclamation mark)

- NVIDIA GeForce GTX 1050

Since I'm not very familiar with the subject matter and have had rather bad experiences with official "PC-specialists", hopefully someone can help me here.

Can be due to software, just reinstall the drivers (the latest)

may also update Windows

I have drivers automatically, then reinstalled manually. Did not bring anything. Windows is up to date.

Probably the graphics card is over, but why you can't control the brightness of the screen does not light up to me.

If you still have warranty, send it in. I would always advise against these gaming laptops, because of the usually too weak cooling, the components say goodbye sooner than they should.
