How to troubleshoot your Smart Monitor M80B when connecting a device to the USB-C port

Depending on the connection status and specifications of your USB cable, the screen output may not be optimal. Also, please make sure that your monitor’s USB-C Preference function menu setting is set to High Resolution.

You can choose to prioritize High Resolution or High-Speed Data transfer. If you change your settings during a data transfer, your transfer may be canceled, or your data may be corrupted. From Menu, you can change the USB-C Preference setting.

Step 1. Press the Home button on the Smart Remote and navigate to Menu.

Step 2. Select Settings > All Settings.

Step 3. Select Connect > External Device Manager.

Step 4. Select USB-C Preference setting > High Resolution or High-Speed Data.

• High Resolution: If High Resolution is selected, 3840x2160@60Hz is the optimal resolution. Up to USB 2.0 port is supported.
• High-Speed Data: If High-Speed Data is selected, up to USB 3.0 port is supported. In this instance, 3840x2160@60Hz cannot be used with USB-C input. If 3840x2160@60Hz input is desired, please select and use “High Resolution”.

You can choose to use USB devices (keyboard, mouse, etc.) from your monitor or from an external device connected to the USB-C port. If you set the USB Source setup to Auto, the setting automatically and conveniently changes, depending on your monitor display output. You can change the USB Source setup from Menu.

Step 1. Press the Home button on the Smart Remote and navigate to Menu.

Step 2. Select Settings > All Settings.

Step 3. Select Connect > External Device Manager.

Step 4. Select USB Source Setup > Auto/USB-C/Monitor.
