@Gecca a simple USB-C to HDMI cable should absolutely allow you to run the external display in Extend mode. The multi-output adapters are the ones to be wary about. Some of them will ONLY allow you to use mirroring across any displays attached that way, whereas others (including the specific item you linked) will allow the attached displays to be used independently of each other. But when dealing with a single display, this shouldn't be an issue at all. If you connect the external display and go to Settings > System > Display and scroll down to the "Multiple Displays" section, do you not have an option that says "Extend these displays"? If not, what if you check Intel HD Graphics Control Panel (or Intel HD Graphics Command Center, depending on the driver version)?
@Gecca glad it worked. As for that thread you linked, you'll notice that there are a few posts of mine in there. Unfortunately the first answer from Mary G about the system's capabilities simply wasn't accurate. But the real issue in that case was that the person who asked the original question in that thread was trying to run two external displays that would be independent from not only the built-in display but also from each other, i.e. three independent displays total when counting the built-in display. That's different from running a single external display that is independent from the built-in panel as you're doing. And the problem in that person's case was that the adapter they were using only supported receiving a single display signal from the source system, so if you connected two displays to it, then the two external displays would be mirrors of each other -- but they were still independent of the built-in display.

Hi,
Thanks for the quick reply.
And you're right, that seemed to run contrary to what I read in this thread:
https://www.dell.com/community/XPS/XPS-13-9360-dual-monitors-will-only-mirror/td-p/7272029
But tried again and it worked.
Thank you very much
