Maintenance
- Keep the monitor clean by gently wiping the screen with a soft, lint-free cloth. Avoid using harsh chemicals or abrasive materials.
- Store the monitor in a cool, dry place when not in use.
- Handle the swivel hinge and connections with care to prevent damage.
Troubleshooting
- No Display/Signal:
- Ensure all cables are securely connected.
- Verify that the monitor is receiving adequate power. Use the provided power adapter if necessary.
- Check your laptop's display settings to ensure the external monitor is detected and configured correctly (Extend or Mirror mode).
- Confirm your laptop's USB-C port supports video output if using a single USB-C cable.
- No Sound: The monitor does not have built-in speakers. Audio will play through your connected laptop's speakers or other external audio devices.
- Incorrect Aspect Ratio: The default aspect ratio is 16:10. You can manually change it to 16:9 through the monitor's OSD menu.
- PS5 Connection Issues: The monitor does not support 1440P output when connected to a PS5. Adjust the PS5's video output settings to a supported resolution (e.g., 1080P).
- Unstable Attachment: Ensure your laptop screen is within the recommended 14-17 inch range for optimal fit. Adjust the extender's frame for a snug fit.
