Personal Computer - Displaying PC screen on TV

    Before Connecting

    The following guide will help you to connect your computer to your TV.

    Before you proceed, it is recommended that you download the latest driver and software version of your graphic card. For more information, please visit your graphic card or computer manufacturer's website.
    Most computers have a HDMI output port, so you can use the HDMI cable to connect your computer to the TV.

    • HDMI
      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 the HDMI jack (socket) that carries the "ARC" mark. If not, an additional audio connection to PC/HDMI AUDIO IN is necessary.

    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.)
    • TV 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.)
    • Depending on the connection status, the image may be blurred or smeared. In this case, change the PC’s settings and select another input signal "Corresponding PC input signal".
    • 1920 pixel x 1080 line/ 60Hz output may not be available, depending on your PC. Even if 1920 pixel x 1080 line/ 60Hz output is selected, the actual output signal may differ. In this case, change the PC’s settings and  select another input signal "Corresponding PC input signal".
