Which cable do I need?

[EdMetal]

I found out that the way to connect my laptop to an external screen, while using the dgpu, is through the usb-c port, that should work as a dp 1.4 port, if the nvidia panel is to be believed. Since I don't have optimus, this should be a way to gain some fps.

However, the monitor I intend to use doesn't have a free dp port. Now my question is: if I buy and usb-c to hdmi cable, will it work the same?

Am I forced to buy a usb-c to dp and then buy a converter from dp to hdmi in?

There is not only a DP alt mode for USB-C but also a HDMI alt mode which means a USB-C to HDMI cable could be relying on this very alt mode to be activated. If your laptop supports HDMI alt mode this shouldn't be a problem. If it doesn't it might be worth researching if the USB-C to HDMI cable has a DP-to-HDMI adapter built in already. If not I'm afraid your out of luck and have to chain a USB-C->DP and a DP->HDMI adapter together.
