How to connect the TV to other devices?

TV Connectivity Guide.

    This guide is intended to help in your understanding of high definition and standard definition videos, as well as assist in connecting your audio and video devices in the best possible way.

    High Definition vs. Standard Definition 

    Standard definition (SD) videos (i.e. NTSC, PAL, SECAM) are signals of a resolution between 480 and 576 horizontal lines.

    High definition (HD) videos are signals of a resolution between 720 and 1080 horizontal lines.

    You can compare HD and SD to digital photography: a 10 million pixels picture printed on a 10x15 cm paper will not look much better than a 5 million pixels picture printed on the same format. However, if you print the same pictures on a 40x30 cm format, the difference will be huge.

    On a small display, you will not necessarily see the difference between both. You may notice a difference in colours only, as the colour gamut of high definition pictures is wider.

    However on a larger screen (from 32 inches with at least 720 horizontal lines or vertical pixels), the difference becomes very noticeable.

    Before connecting your devices...

    The signals that enter the TV and connected devices will need to be output in the correct format using the suitable connections. Below are the different types of video connectors. When connecting the TV, use the inputs that are available on your devices that provide the best video performance.

    Video performance level



    Signal transmitted

    Separate audio connection required

    HDMI Picture + Sound No
    DVI*1 Picture Yes
    Component video Picture
    S-Video Picture
    Composite video Picture
    RF/Coaxial Picture + Sound No

    *1 If the equipment has a DVI jack and not an HDMI jack, connect the DVI jack to the HDMI IN (with HDMI-to-DVI cable and/or adapter jack), and connect the audio jack to the AUDIO IN (L/R) jacks of HDMI IN. (The DVI connector is for video signals only)
    To enjoy the best visual experience with your system, it is preferable to connect your best devices with the highest quality connections available. For example: your Blu-Ray Disc player or HD Set Top Box with HDMI, followed by your DVD player with Component, then your Video Cassette Recorder with S-video etc.

    Note: The quality of the picture also strongly depends on the quality of the cable used.


    The High-Definition Multimedia Interface (HDMI) is an all-digital audio/video interface capable of transmitting high definition video and audio signals. HDMI provides an interface between any compatible digital audio/video source, such as a set-top box, a DVD player, a PC, a video game system, or an AV receiver and a compatible digital audio and/or video monitor, such as a digital television (DTV).


    The Digital Visual Interface is capable of transmitting high definition video, but does not transmit sound. You will need to use the audio connectors of your device (usually Optical/Coaxial digital, or RCA). It is possible to connect an HDMI device to a DVI device using a HDMI to DVI adapter.

    Component video

    Component video is an analogue connection. It is capable of transmitting high definition signals. Component does not transmit sound. You will need to use the audio connectors of your device (usually Optical/Coaxial digital, or RCA)


    Separate video, abbreviated S-Video and also known as Y/C is an analogue video signal that carries the video data as two separate signals (brightness and colour), unlike composite video which carries the entire set of signals in one signal line. S-Video, as most commonly implemented, carries standard definition video. It does not carry audio on the same cable.

    Composite video

    Composite video is an analogue video (no sound) format. This is the connector you should use if you do not have any other connector available, in terms of quality.


    RF Coaxial Cable connection is used for transferring television signals (audio and video) originating from an antenna or cable box to a Television.
