(Universal Serial Bus) is an innovation in connecting your different
desktop peripherals conveniently to your computer. By using the USB, you will
be able to connect your mouse, keyboard, and other peripherals to your display
instead of having to connect them to your computer. This will give you greater
flexibility in setting up your system. USB allows you to connect a chain of up to
120 devices on a single USB port; and you can "hot" plug (attach them while
the computer is running) or unplug them while maintaining the Plug and the
Plug auto detection and configuration. This display has an integrated BUSpowered USB hub, allowing up to 2 other USB devices to be attached it.
