Some TouchSmarts include an additional video slot to which a second monitor can be connected. Depending on the age of the device, the TouchSmart could come equipped with either a high-definition multimedia interface, video graphics array, digital video interface or separate video socket. You can connect an additional monitor to duplicate the screen onto a larger display -- thereby getting a better view of your workspace -- or extend the screen across both monitors, allowing you to work on multiple projects simultaneously.

Step 1

Open a Web browser and navigate to HP Customer Care.

Step 2

Press "Ctrl-Alt-S" or "Fn-Esc" to find your HP TouchSmart's product number. Enter the product number into the search field and then click "Next."

Step 3

Click "Manuals." Select "Maintenance and Service Guide" or "Notebook Tour" from the list of documents.

Step 4

Select "Front-Side Components" from the table of contents. Browse through the list of components -- including those located on the left, right and back sides -- to find the location of the HDMI, VGA, DVI or S-Video connector.

Step 5

Connect the monitor cable to the appropriate adapter, if applicable, and then plug the cable or adapter into the video socket on the HP TouchSmart.

Step 6

Confirm the monitor cable is connected to the display. Connect the monitor to power.

Step 7

Press "Windows-D" to minimize all open windows. Right-click the desktop and then click "Screen Resolution."

Step 8

Click "Detect" if the HP TouchSmart doesn't automatically recognize the second monitor.
