For Online Computer Support, Ask a Computer Technician
You need to have a video card in your laptop. If you do, you need to install the driver for being able to see your computer on your TV. Go here: http://welcome.hp.com/country/us/en/support.html
and enter your compaq version e.g. Pavilion 7955, LaserJet 1100 or C4224A and CHECK "Download drivers..."
Then, after following instructions and rebooting your computer, you can RIGHT click your desktop, Click properties, go to "settings\advanced\view" and you will see where you can ENABLE your TV.
Of course, you must have a video card that has SOUT (ask your store when you buy the card) and of course you need the proper cable to connect the computer to the TV.
