As pointed out, the laptop is THE computer. The other monitor is just an extension of the laptop screen. Kind of like attaching your laptop to a projector during meetings/presentations. He then attached an external KB and mouse using USBs. I use multi-monitors at home and the office. having 2 monitors is great even before the pandemic for me. You can edit a document in one screen, edit figures or run command-line scripts/codes in another. For online meetings, one screen can be the gallery of the participants or the speaker and the chat box, the other yours or the speakers presentation.
