HDMI

• 1). Check your computer and television to see if they both have a High-Definition Multimedia Interface (HDMI) connector. An HDMI port resembles a USB port, but is rounded along the top corners. The port should be labeled "HDMI."
  
  
• 2). Connect an HDMI cable from the HDMI port on your computer to the port on your TV. HDMI cables are able to easily transmit data across lengths of up to 15 meters (m).
  
  
• 3). Boot your computer and enter the settings to change video output to HDMI. Most computers automatically detect the cable, so this may prove unnecessary. Press the "FN" and "F5" keys at the same time to scroll through available video modes if using a laptop computer.
  
  
• 4). Turn on the television and use its setup menu to change the video input source to HDMI. Most remote controls have a "Source" button, which should make changing the source easy.
  
  
• 5). Adjust your computer's sound properties if you have no sound from the television. Right click the speaker icon in the system tray and select "Playback devices" in Windows 7. Select HDMI in the window that opens, then click the "Set as Default" icon at the bottom of the window.
  
  

S-Video

• 1). If no HDMI ports are available, connect your PC to the TV using a Separate-video cable, commonly called S-video. Most laptops and the majority of desktops have an S-video out connector, and most TVs have an S-video in connector. You can recognize an S-video port by its round shape with either four or seven round holes and two square holes in the middle.
  
  
• 2). Enter the video settings on your computer and ensure that the external display is set to clone the computer display. Occasionally the default setting is used the external video monitor to expand the screen area. You can do this easily on a laptop by pressing the "FN" and "F5" keys and scrolling through the options.
  
  
• 3). Set the TV's video source to S-video by using the TV's menu features. Most remote controls have a button that allows you to quickly scroll through the possible video source options.
  
  
• 4). Add sound to the S-video setup. Use the audio line-out port on your computer to connect to the audio line-in port on your TV or connect external speakers to the PC audio line-out jack. If your TV doesn't have a 3.5 millimeter (mm) line-in jack, you can buy an adapter that allows you to plug the line-in cable to the TV's RCA audio connectors. This is necessary because unlike HDMI, S-video only transmits video.
  
  

VGA

• 1). Use Video Graphics Array (VGA) as a last resort to connect your PC and TV. This will give you the lowest quality video image, but most computers have this connector available. You can identify a VGA port by the three rows of five holes each. The VGA cable connector has 15 pins that plug into the holes. Connect a VGA cable to the VGA out port on the computer and the VGA in port on the TV.
  
  
• 2). Use a VGA to Digital Video Interactive (DVI) adapter if your computer lacks a VGA port but has a DVI connector. VGA to S-video and Radio Corporation of America (RCA) adapters are also available, allowing you to connect almost any PC to your television.
  
  
• 3). Set the TV video-in source to VGA and ensure the PC duplicates what shows on its display. If you use a desktop computer and connect the VGA port to the television, this will happen automatically.
  
  
• 4). Add sound to the arrangement the same way you would add sound to the S-video set up. Unfortunately, VGA only transmits video.
