Why does the monitor connected to the DisplayPort not work?

When connecting a monitor to the built-in DisplayPort on one of our Thunderbolt 3 devices and it doesn't work, please check the following items.

Passive vs active adapters
The DisplayPort does not support DP++, so when using a passive adapter (e.g. passive HDMI to DisplayPort adapter), the monitor will not be recognized. Please use an active adapter instead. These kind of adapters usually include the word "active" in the description and tend to be more expensive than the passive adapters.
