The USB Graphics Adapter provides a unique solution to add extra displays to a
computer without using additional graphics cards. This product has successfully challenged
the limitations of current display connectivity to deliver a highly interactive user experience
across USB 3.0 or USB2.0 connectivity. Users can instantly clone or extend a desktop onto
another display via DisplayPort, HDMI, DVI or VGA (D-Sub) interface, such as LCD, CRT,
projector and plasma displays. With USB interface plug-n-play and bus power feature, this
product brings multi-monitor applications into the mainstream.

Overview
SuperSpeed USB interface is the next revo lution in I/O interconnect standards that will
deliver the bandwidth and features required by PCs, consumer electronics and
communications devices. With 10 times faster throughput than USB 2.0 standard, USB
Graphic adapter enhances better VGA performance effect and reduce CPU loading
substantially.
With this handy adapter, you can enjoy many benefits brought by an add-on monitor. The
most obvious one is that you get more desktop area to have more applications visible at one
time. For example, you may work on one monitor while your family watches video on the
other. No more stacking windows within the confines of a single display. Or you may span an
application, e.g. spreadsheets, across two displays. What's more, the adapter is hot
pluggable. If you are not using the extra monitor, just unplug the adapter at any time; no
reboot needed.
