How to connect the computer to the TV via cable?

Applicable Products and Categories of This Article

How to connect computer to TV via cable (HDMI or VGA as recommended cable), and use television as an external display of your computer. Depending on the ports available on your television and computer, it is possible to connect your computer to television – using the television as a monitor.


The following guide was designed to help you to connect your computer to your TV.

Note: Before you proceed, it is recommended that you download the latest driver and software version of your graphic card. For more information visit your graphic card or computer manufacturer Website.


Because almost every computer has an output port, you can use a cable to connect your computer to television. Most computers have a VGA output port, so using VGA cables is very common. Other recommended connection is via HDMI cable.

  • VGA
    Intel®
    The Video Graphic Array is capable of transmitting high resolution analogue video, but does not transmit sound. You will need to use the audio connectors of your device.


    * It is recommended to use a PC cable with ferrites, such as the “Connector, D-sub 15” (ref. 1-793-504-11, available in Sony Service Centre), or an equivalent.

  • HDMI
    Intel®
    The High-Definition Multimedia Interface (HDMI) is an all-digital audio/video interface capable of transmitting high definition video and audio signals. However, not all HDMI-enabled video cards support audio. If your HDTV has an audio input, you might be able to connect a separate audio cable from your computer sound card directly to the TV. Otherwise, you'll need to connect the audio signal to a different device, such as external computer speakers or your home stereo system.

Notes on Audio Connectivity:
If connecting a digital audio system that is compatible with Audio Return Channel (ARC) technology, use HDMI IN 1 (ARC). If not, an additional audio connection with is necessary to PC/HDMI AUDIO IN is necessary.

 

Note if your computer has DVI or Mini-DVI port:
You can connect it to the HDMI (with AUDIO IN) port through a DVI - HDMI adaptor interface (not supplied), and connect the device’s audio out port to the PC/HDMI AUDIO IN.


Corresponding PC input signal

(Resolution, Horizontal frequency/Vertical frequency)

  • 640 x 480, 31.5 kHz/60 Hz
  • 800 x 600, 37.9 kHz/60 Hz
  • 1024 x 768, 48.4 kHz/60 Hz
  • 1280 x 768, 47.4 kHz/60 Hz and 47.8 kHz/60 Hz
  • 1360 x 768, 47.7 kHz/60 Hz
  • 1280 x 1024, 64.0 kHz/60 Hz (Full HD model only)
  • 1920 x 1080, 67.5 kHz/60 Hz (Full HD model only)*
    * The 1080p timing, when applied to the HDMI input, will be treated as a video timing and not a PC timing. This will affect the System Settings and Display settings. To view PC content:
    - Set Scene Select to Graphics
    -
    Set Screen Format/Wide Mode to Full
    - Set
     Display Area to Full Pixel. (Display Area is configurable only when Auto Display Area is set to Off.)

Notes:

  • This TV’s PC input does not support Sync on Green or Composite Sync.
  • This TV’s PC input does not support interlaced signals.
  • For optimum picture quality, it is recommended that you use the signals in the chart. In plug and play, signals with a 60 Hz vertical frequency will be detected automatically. (PC reboot may be necessary.)
