Multiple Monitors

Most laptops, tablets, and even desktop PCs these days have video-output
jacks. Some new tablets and laptops even offer WiDi (wireless display)
technology. In either case, you can hook up a second monitor (or even third

monitor) or a projector.

You can either display the same picture on both screens (which is what you
want if your laptop is projecting slides for an audience), or you can create a

gigantic virtual desktop, moving icons or toolbars from one monitor to
another. The latter setup lets you keep an eye on web activity on one
monitor while you edit data on another. It’s a glorious arrangement, even if

it does make the occasional family member think you’ve gone off the deep
end with your PC obsession.

Over the years, PC makers have offered different kinds of connectors for

external screens—jacks called things like VGA, DVI, HDMI, DisplayPort,
and USB-C. Alas, it’s your burden to figure out which jack your computer
has and to get the right kind of cable or adapter to accommodate your

external screen.

Once you’ve done that, treat yourself to an Oreo milkshake to celebrate.
