What factors determine how many external screens (monitors/displays) a laptop can support?
For this specific question, let's define several parameters:
- we are working with modern (2023) technologies
- minimum resolution of 1920x1080 pixels per screen (1080p)
- each screen needs to display its own content (no mirroring)
- each screen requires graphics acceleration (to play video, perform 3D CAD manipulations, etc.)
- allow dragging windows between screens
- strongly prefer that the laptop's integrated screen also be used in conjunction with the external screens, but this is not a hard hard requirement
