Does it have built-in battery?
Yes, it has built-in 10800mAh battery, so that you can work remotely with this monitor.

Why there are no signal?
Make sure your pc/laptop has "True" Thunderbolt 3 USB-C port for this to work, some laptop/pc only has USB 3.2 Gen 2 Type-C port but without Thunderbolt 3 or DP.
