Displaying video from a PC on a television screen

October 2016

With revolutionary technology in hardware , video can now be displayed on a television screen from a PC. To enable this, two conditions have to be satisfied. The graphics card of the PC must have a TV output which is either a S-video or RCA output and if both are not present, then an additional hardware VGA box will be required. The TV must also have a SCART adaptor or S-video entry. The desired configuration is set through the control panel. The view option can be activated through the settings tab. Once the TV is connected to the TV output, the display gets ready. TV signal can be checked through AV mode on the television screen. For better resolution and clarity, one should ensure that the resolution of the TV and the monitor, as well as the I / O standards, remain similar.

You can display the output from the computer on a television (or even the sound on an amplifier). This requires a graphics card with a TV output and a TV with SCART or S-Video entry.

TV output

The output of the graphics card is usually an S-Video (mini DIN 6-pin), also called S-VHS. Sometimes there is also an RCA output. If the graphics card does not have any of these connectors, consider changing your graphics card or invest in a piece of additional hardware called a VGA Box.

S-Video output

If using an S-VHS output, an S-Video cable must be used to connect the computer to the S-video TV or in other cases to an S-Video/SCART adapter.

Note: Full S-Video support is not a feature of many graphic cards, causing a black and white display. To solve this problem, simply open the S-Video/SCART adapter and bridge terminals 15 and 20.

RCA output

The same goes when using a RCA output, but using a RCA cable.

Configuration under Windows

  • Activate the TV output via the control panel:
    • Double-click on display, then choose "Settings" tab
    • Click on "Advanced" tab and choose the View option
    • On Nvidia, the option is present in Start/Panel configuration/NVidia desktop manager /NView
  • If the TV is connected to the TV output, a TV screen with the designation "connected" should appear
  • Select the Clone Monitor/TV and validate
  • Check the presence of a signal from the computer by pressing the "AV" button on the television until it switches on the TV display
  • Restart the computer if there is no transmission to the TV.


Why does the image on the TV flicker?

If the resolution of the TV is not identical to that of the monitor the display will flicker. Return to the configuration options, click the right mouse button on TV (monitor No. 2), then choose resolution and clarify 800x600x32 bit in 60 Hz (or 50 Hz if available).

Why is the image in black and white?

The problem often comes from video standards (the PAL), so check that the standards I/O are identical.
