To use a PC at all, you need a monitor??”but to use your PC to the max, you may
need two monitors??¦or maybe many. Most people find that the more they can
see onscreen, the faster they can get their computing done.

it??”and that??™s even if it doesn??™t have an external display port.
This project starts at the sane end of the spectrum by assessing your options and
discussing how to add one more monitor to your desktop or laptop. But then the project
veers across to the enthusiast extreme??”adding three monitors to a laptop and up
to ten monitors to a desktop.

is already equipped to drive another monitor, and all you need do is connect it.

PCs use two main types of video connector for their monitors:

were even larger.) The illustration here shows a D-sub connector.
