Laptops can be connected easily to Samsung TVs only if they both have VGA input/output devices. If so, then all you need is a VGA cable. Computer displays work in RGB (red, green, blue) colour space, and a TV with a VGA input is designed to handle this format. You may need to change a few settings in your computers to display a proper picture. As of September 2010, VGA inputs on TVs have become more common because of the growing number of compatible multimedia laptops.

  1. 1

    Connect one end of the VGA cable to your laptop.

  2. 2

    Connect the other end of the VGA cable to the VGA input of the TV.

  3. 3

    Change the channel on the TV to the proper input channel.

  4. 4

    Activate your computer's display settings to adjust to a second monitor. In Windows, this is done with the "Display Settings" utility in the control panel. On a Mac, it is done in the "Displays" section of "Preferences."

  5. 5

    Adjust the resolution if necessary and whether to extend the desktop onto the TV. Click "OK" to apply the changes.

Tips and warnings

  • While it is possible to connect a VGA cable to a TV via the component or composite inputs, it requires an extra device called a transcoder, which can cost between £32 and £130.
