Adding 2 external monitors without dock

Yes, you can use HDMI and USB c to extend the desktop assuming your monitors are new enough to support those.

It will be spaghetti junction there with a mouse, keyboard, headset too. That’s what the dock gives you, a much tidier setup, and you won’t need to reconfigure everything once you plug out and plug in.

To set it up either direct cabled or with a dock is the same.

1)plug it all in
2)press WINDOWS button +P to bring up the display setting dialog (or search for it in settings).

3)Click detect additional monitors
4)select Extend
5) select Identify
6) drag the pictures of the monitors around in the screen until they match your physical layout.
