external monitor for notebook

MSI GL75 notebook,Intel UHD Graphics(630 Gen9.5),Nvidia gtx 1660 Ti.Archlinux,XFCE4.
Is it possible to connect an external monitor using only the Intel driver for output HDMI?

Re: external monitor for notebook

if hdmi port(s) is on the dGPU i donk think so.
if port(s) is on the mainboard maybe.

In any case you must test to know exacly.

Please use [code][/code] tags. Edit your post in this regard.
There're no indications of any nvidia GPU and all three outputs (eDP1, HDMI-A-1 and DP-1) are wired to the same (and only) intel card?

Re: external monitor for notebook

When installing the system, no programs related to nvidia were installed.
I was satisfied with everything.
a month ago inxi -Gsaz

Device-2: NVIDIA TU116M [GeForce GTX 1660 Ti Mobile]
vendor: Micro-Star MSI driver: nouveau v: kernel non-free: 550-570.xx+

When trying to configure the notebook, nouveau was disabled?.
I don't remember where.

Please post your complete system journal for the boot:

sudo journalctl -b | curl -F 'file=@-' 0x0.st

and the output of "lspci -k", inxi, neo/screen/whateverfetch are nice for screenshots on r/unixporn, but not very reliable when it comes to illustrating the system configuration.
