Computers have become all-out media centers, capable of playing movies, music, and video games and even of streaming live television. Modern computers also come with an assortment of ports and outlets that allow easy connectivity to other devices, including televisions. Today's HDTVs can display high-resolution images ideal for showing off the media available on your computer, and they're relatively easy to connect.
Determine which type of cable to use; it will depend on which ports both your computer and TV share. Older computers and TVs will only have S-Video or VGA ports. Ideally, your computer and TV will both have HDMI ports, which allows for high-definition video and audio transfer. Consult your owner's manuals for port identification before deciding on which cable to use. Connect the computer's video outlet, either HMDI, VGA, or S-Video, to the TVs corresponding video input. These will usually be on the back of the TV and will be clearly labeled. Turn on your TV and set it to the proper video channel, which will correspond with the type of cable you have used. Some TVs have multiple ports for the same connection. Just set the video channel to whichever port you have used--for example, "HDMI 1" or "HDMI 2." On your computer, right click on your desktop and highlight "Graphics Properties," prompting a submenu to pop up. Highlight and click "Output to TV." Your computer's images should now be displayed on the TV instead of the monitor. how to connect your PC or computer to a TV http://www.online-tech-tips.com/computer-tips/how-to-connect-your-laptoppccomputer-to-your-tv/
