Connecting to Devices

- HDMI + USB-C (Power): For devices with HDMI output, connect an HDMI cable from your device to the monitor's Mini HDMI port. Then, connect the power adapter to the monitor's 'Power Only' USB-C port to ensure sufficient power for optimal brightness.
- Dual Device Connection: You can connect two different devices simultaneously, one to each screen, using a combination of USB-C and HDMI cables. This allows for independent use of each display.

5. Maintenance
To ensure the longevity and optimal performance of your UPERFECT Delta monitor, follow these maintenance guidelines:
- Cleaning: Use a soft, lint-free cloth slightly dampened with water or a screen-cleaning solution. Avoid harsh chemicals or abrasive materials.
- Handling: Always handle the monitor with care, especially when folding or adjusting the stand. Avoid applying excessive force to the screens or hinges.
- Storage: When not in use, fold the monitor into its compact form and store it in a safe place to prevent scratches or damage.
- Ventilation: Ensure proper ventilation around the monitor to prevent overheating. Do not block the ventilation openings.
6. Troubleshooting
If you encounter any issues with your UPERFECT Delta monitor, refer to the following common troubleshooting steps:
- Dim Screen/Flickering: If the screen appears dim or flickers, it may be due to insufficient power. Ensure the monitor is connected to the power adapter, especially when using a single USB-C cable that might not provide enough power from the host device.
- No Display: Verify that all cables are securely connected to both the monitor and the host device. Try using different ports or cables if available. Ensure the host device's display settings are configured to extend or duplicate the display.
- Incorrect Display Mode: Use the OSD controls on the side of the monitor to manually switch between Clone, Extend (DP MST), or Link modes.
- Screen Orientation Issues: The monitor has a built-in gravity sensor for automatic rotation. If the orientation is incorrect, try rotating the monitor 180 degrees or check your device's display settings for manual rotation options.
- Sound Issues: If there is no sound, check the volume settings on both the monitor's OSD and your connected device. Ensure the correct audio output device is selected on your computer.
