How to connect a PC/Laptop to your HDTV using an SVGA cable

Connect a computer to an HDTV set using an SVGA cable so that images displayed on the computer can also be seen on the TV. Most HDTV sets have a number of inputs available for signals from various sources such as HDMI, cable and SVGA. Most computers have support for multiple monitors built into the operating system, and many allow multiple video cables to be connected simultaneously. Watch streaming web content, photo slide shows or other video output on the HDTV by connecting the SVGA cable and making a few minor adjustments to the resolution and video settings.

  1. Power off the HDTV set.

  2. Click "Start" and "Shut Down" to power off the computer.

  3. Place the SVGA M-M HDD15 video cable in a location that will make it easy to connect to the television and the computer.

  4. Push the end of the SVGA M-M HDD15 video cable into the matching port on the back of the computer or laptop. Twist the cable retaining screws a few turns to keep the cable in place.

  5. Push the other end of the SVGA M-M HDD15 video cable into the matching port on the back of the HDTV. Twist the cable retaining screws a few turns to keep the cable in place.

  6. Power on the HDTV and select the "SVGA" or "VGA" input as the source.

  7. Power on the computer or laptop. If the display does not show up on the HDTV or the image is distorted, you may need to adjust the settings on the video card. Click "Start" and "Control Panel." Click "Adjust Screen Resolution" under "Appearance and Personalization." Click "Detect" at the top of the screen to detect the HDTV as a monitor. Select "Duplicate These Displays" in the "Multiple Displays" pull-down menu to show the same image on the main computer display and the HDTV, or select "Extend These Displays" to make the HDTV an extension of the desktop. Adjust the resolution until the image on the HDTV clears up.

  8. Tip

    Obtain the best results by experimenting with different resolutions and refresh rates on the computer. For cable runs of more than 15 feet, use a video extender device to avoid signal loss.


    Don't connect or disconnect the video cable when either the computer or the television is on, as this can occasionally cause a damaging electrical current to surge through either device. Power down the computer using the "Shut Down" command from the "Start Menu" instead of putting the computer into "Sleep," "Standby" or "Hibernation" mode. If unsure of the current system state, start the computer up and click "Start" and "Shut Down" to properly shut down the system. Avoid placing the cable where it will run across the open floor and cause a trip hazard, or placing it in direct contact with heaters or electrical transformers such as those on many power cables for various devices -- they may cause video interference. Twist the retaining screws a few turns to set them snugly to the computer or TV, but do not tighten them up as they are only designed to keep the cable from falling out. Over-tightening can cause the metal standoffs to come out of the computer when you disconnect the cable.
