Adding a Monitor Using an HP USB Graphics Adapter
This document pertains to HP All-in-One and TouchSmart PCs with Windows 7 and an HP USB Graphics Adapter for connecting a monitor and extending the Windows desktop.
You can connect a monitor to your computer as the primary display or secondary display (monitor). This document describes how to connect a monitor to a TouchSmart or All-in-One PC using the HP USB Graphics Adapter.
Because the TouchSmart or All-in-One has a built-in monitor, an extra graphics card or graphics connectors are not available. For this reason, to add a monitor you need a HP USB Graphics Adapter. This adapter provides a way to connect additional displays through the USB ports on a TouchSmart or All-in-One. This allows you to:
- Add up to six monitors (one per USB port and adapter) to one computer.
- Extend the Windows 7 desktop across multiple monitors.
- Mirror your primary screen, or view more applications at the same time.
- Add DVI or VGA monitors.
- Automatically install the DisplayLink driver and the DisplayLink Graphics Adapter software.
CAUTION:If you have an HP TouchSmart, use the HP USB Graphics Adapter to duplicate (mirror) your displays. HP TouchSmart software was not designed to operate with additional displays operating in extended desktop mode. TouchSmart software is fully compatible with graphics adapter software if used in mirror mode. To setup a TouchSmart PC in mirror mode, see Configuring multiple displays in Windows 7 below.

|The display does not appear as a device in graphics software.||If you connected the monitor after the software was opened, close the software and open it again. Some software does not recognize a display added or attached while the software is open.|
|Picture quality issues.||Use a USB cable five meters (16 feet) or less in length. Longer distances can result in signal degradation and possible loss in audio and video quality. For longer distances, or for viewing 1080P or higher video definition, use a higher quality cable (Category 2) or a signal amplifier.|
|Blank or missing tiles in the TouchSmart window|
Blank or missing tiles may be displaced to the secondary monitor.
Intermittently, the touch screen calibration might be off significantly in both the TouchSmart software screens and in the Windows interface.
|HP TouchSmart software was not designed to operate with additional displays operating in extended desktop mode.
