Universal Serial Bus
Making use of USB (Universal Serial Bus)*
USB(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
monitor 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 chain 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 Plug and Plug auto detection and
configuration. This monitor has an integrated Bus-powered USB hub, allowing up to 2 other USB devices to be
attached it.
USB connection (Option)
(1) Connect the upstream port of the monitor to the downstream port of the USB
compliant PC or another hub using the USB cable.
(2) Connect the USB compliant peripherals to the downstream ports the monitor.
*USB(Universal Serial Bus) is supported WINDOWS98 and Higher.
USB Downstream Ports

peripherals-such as keyboard, mouse etc.
