Nitro 5 AN515-57-520Y with i5 11400H and NVIDIA RTX 3050.

I connected to my LG C1 TV today for the first time via HDMI 2.1 cable.
However:
a) I can't project the image to just the TV. Either through the shortcut Windows + P, or in Display Settings, whenever I change to Second Screen Only on Monitor 2 (TV) the system automatically reverts to the duplicate the video signal setting.

b) When I connect to the TV, NVIDIA Control Panel starts displaying the other options in the left pane, including G-SYNC and change resolution. But whenever I select PC > 4K @ 120Hz or 2560x1440 @120Hz resolution, PC automatically reverts to 4k @60Hz. GSYNC is set up and enabled on the PC and TV as well.

c) Through Intel Command Center, I can't disable the laptop monitor to force display only on the TV.

It seems to me that the notebook, at the firmware/BIOS level, simply does not allow disabling the integrated monitor and does not allow the Nvidia GPU to take over during normal use - the 3050 is only active in games or when I connect the notebook to an external monitor.

I don't know how to proceed.

    What happens when you temporarily disable the Intel adapter in Device Manager Display adapter folder?
