1. Introduction
This USB Display Adapter enables you to connect one more monitor, LCD or projector to a
computer with a USB 2.0 port. For desktop users adding an extra monitor via USB
connection is easier than ever without having to open the computer chassis to install an
internal video card. Once the installation is done, the USB-attached monitor soon wakes up.
No function key hassle to swap a second monitor.
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 watching 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 sides of 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.
System performance is an important issue when using multiple monitors. Another benefit of
this adapter is that it uses little computer resource; ensuring users get quality display
without comprising computer performance.
