There is no image on the external monitor, what's the problem?

Question

Monitors

When connecting the BenQ GW2760HS monitor to an HP Omen 17-an013ur laptop with an HDMI cable, there is no signal.
The same cable and monitor work fine with the stationary.
The laptop monitor is visible in the settings of the Intel GPU, the external monitor is in the NVIDIA settings (GTX 1050), but the image is only on the built-in monitor.
I tried to update the drivers, install from the HP website and the original ones, it did not help.

Answer 1

As funny as it sounds, try a different cable. HDMI is surprisingly capricious to the cable, I personally have repeatedly run into what you described because of the cable.

Answer 2

Can two laptop video cards work simultaneously, or only alternately?
