How to Hook Up a Second Monitor to a HP TouchSmart Computer
By Ruri Ranbe
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.
Open a Web browser and navigate to HP Customer Care.
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."
Click "Manuals." Select "Maintenance and Service Guide" or "Notebook Tour" from the list of documents.
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.
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.
Confirm the monitor cable is connected to the display. Connect the monitor to power.
Press "Windows-D" to minimize all open windows. Right-click the desktop and then click "Screen Resolution."
Click "Detect" if the HP TouchSmart doesn't automatically recognize the second monitor.
