Before installation

Acclimate the display

Play the included demo content

The Demo Media Player arrives connected to the display and includes preloaded demo content. No additional video or player cabling is required for your first power-on.

  1. Set the rear AC power switch to OFF.

  2. Connect the supplied AC cable to the display and a compatible power source.

  3. Set the rear AC power switch to ON.

  4. If the display does not start automatically, press the power button on the rear OSD controls or on the remote controller.

  5. Wait for the preloaded demo content to appear before changing inputs.

The display searches for an active input automatically by default. If the demo content does not appear, use the remote's AV/TV button or the OSD Input menu to select HDMI.

The Default Power firmware setting controls whether the display turns on automatically after AC power is applied. This guide assumes that setting is Off, so you need to press the power button. If the setting is On, the display starts when AC power is applied and you can skip step 4.

Use the HLD with an external computer

To use a PC or Mac instead of the included Demo Media Player:

  1. Shut down the computer.

  2. Set the rear AC power switch to OFF and disconnect the display from AC power.

  3. Disconnect the Demo Media Player's HDMI cable from the display. If your computer will use USB-C for video or touch, also disconnect the player's touch/data cable from the display's USB-C port.

  4. Connect the computer to the display using HDMI, DisplayPort, or USB-C with DisplayPort Alt Mode.

  5. If you are using HDMI or DisplayPort and want touch input, connect a compatible USB data cable between the computer and the display's USB-C port.

  6. Connect the supplied AC cable to the display and a compatible power source.

  7. Turn on the computer.

  8. Set the rear AC power switch to ON.

  9. If the display does not start automatically, press the power button on the rear OSD controls or on the remote controller.

A single compatible USB-C connection can carry both video and touch/data.

The display searches for an active input automatically by default. If the computer does not appear, use the remote's AV/TV button or the OSD Input menu to select the connected input.

To return to the preloaded demo content, set the rear AC power switch to OFF and disconnect the display from AC power. Disconnect the external computer, reconnect the Demo Media Player's cables to their original ports, and then follow the steps above.

If you notice smoke, a burning smell, or unusual noise, disconnect the display from power immediately and stop using it.

Check the status LED

Meaning
What to do

Off

The display has no power or is in sleep mode.

Troubleshooting

The display has no image

  1. Confirm that the AC cable is secure and the rear power switch is ON.

  2. If you are using the included Demo Media Player, allow it time to start and confirm its cables are secure. If you are using an external computer, confirm that it is powered on and connected.

  3. Select the connected input from the remote or OSD menu.

  4. If you are using USB-C, confirm that the source and cable support DisplayPort Alt Mode.

  5. If graphics drivers were just installed or updated, wait one to two minutes for the computer to finish starting.

Touch is not responding with the Demo Media Player

The touch function may not respond when the HLD 86" first powers on, or it may stop responding after a period of use.

  1. Locate the USB-C cable connected to the included Demo Media Player.

  2. Disconnect the USB-C cable from the Demo Media Player.

  3. Reconnect the cable securely.

  4. Wait for the touch connection to be restored, then test touch again.

The display shows a yellow status LED

The display did not start correctly. Disconnect it from power and contact support.

The stand is not level

With the display upright and supported, adjust the six leveling feet until the base is stable and level.

Next steps

Once the status LED is green and your source is visible:

  • Use HLD Author to preview and prepare content for the display.

  • Learn how to replace or add to the preloaded content with the Demo Media Player.

  • For long-term deployments, set up a Yodeck or BrightSign digital signage player.
