But only on much shorter cables (up to 1 m) than normal size DisplayPort or HDMI.
In my home, I use 2 monitors. One of them is close enough to the laptop so that an USB-C cable can be used. The second is too far away. If the laptop had no DisplayPort or HDMI, I would have needed a dongle.
Those include the USB-C to HDMI converter in the connector, instead of in a separate dongle.
It is more convenient than the separate dongle, but not as convenient as having a HDMI connector on the laptop.
If you have HDMI on the laptop, you might find a HDMI cable wherever you go. With only USB-C, your only chance is to always carry with you the USB-C to HDMI converting cable.
