Multiple projectors

You can, but you will likely need to use one of these options if your laptop needs to be on for a long time:

-HDMI to USB-C cable

-HDMI splitter (likely also USB-C) to keep one port open for power to your laptop

-a 3rd party program to broadcast content split screen across both projectors unless you are just wanting to broadcast two identical images

-to set display outputs appropriately

Depends on your model/year Mac.

Powerdirector is one option
