    General information about connecting a television to a computer for use as a monitor.

    1. Make sure that the procedure to output the computer screen is performed correctly.
      NOTE: he problem may be solved by turning the device off and on again or disconnecting the cable and connecting it again, even when you follow the procedure shown below. Try following the procedure to output the screen again.
      1. Select a computer screen resolution that is supported by the TV.
        If the TV does not support the resolution set on the computer, the screen image may be distorted or may not be displayed.

        NOTES:
        • For resolutions supported by the TV, refer to the instruction manual of the TV.
        • For how to check/change the computer screen resolution, refer to the help or instruction manual of the computer.
        • It is recommended that you take a note of the computer screen resolution before changing it. (It is necessary when you restore the original setting.)
        • Use a clone or duplicate output with 1080i if it is available on the computer. Some computers are not able to output an HDMI or HD signal in certain video modes.
        • Depending on the specifications of the computer and video card, some resolutions supported by the TV are unable to be displayed. For details, refer to the instruction manual, etc., of your computer and video card.
      2. Turn off the TV and computer.

      3. Connect the HDMI input port of the TV and HDMI output port of the computer via an HDMI cable.
        NOTE: Be sure to use an authorized High Speed HDMI cable bearing the HDMI logo.

        • B: Computer
        • C: HDMI cable (not supplied)
      4. Turn on the TV first, then turn on the computer.
        NOTES:
        • At this point, the input has not been switched to the computer, therefore the picture from the connected computer is not displayed.
        • If you turn on the connected computer first while the TV’s power is off or standby, the computer screen may not be displayed correctly 
      5. Press the Input button of the TV’s remote to change to the input that is connected to the computer.
        Most TV remotes have an Input button that cycles from one input to the next. Press the Input button repeatedly until the correct HDMI input is displayed on the TV. Be sure to check which input on the TV you are connecting to.
        NOTE: The location of the Input button on your remote and the number and names of the inputs may be different on your TV.

      2. On the computer, select a lower screen resolution, then check if the image is output correctly.
      3. When the TV has another HDMI port, connect to it and check if the image is displayed correctly.
