6. Troubleshooting
If you encounter issues with your UPERFECT portable monitor, please refer to the following common problems and solutions:
| Problem | Possible Cause / Solution |
|---|---|
| Screen is dark or not displaying. | Insufficient power supply. Ensure you are using the included power adapter and it is correctly connected to a Type-C port. Other adapters may not provide enough voltage. |
| Flickering vertical stripe on the left side of the screen. | Incorrect cable connection. Verify that the video cable (Type-C or HDMI) is securely connected to the correct ports on both the monitor and your device. |
| No image when connected to a Mac PC. | Mac PCs may require a specific conversion adapter or cable due to proprietary port designs. Ensure you have the correct adapter for your Mac model. |
| HDMI connection is unstable or disconnects frequently. | This could be due to power incompatibility with certain Type-C AC adapters when using HDMI. Try using the included power adapter or a different power source. Ensure the HDMI cable is not damaged. |
| Brightness settings are not saved after sleep/reboot (especially with Mac). | Some operating systems or devices may not retain external display settings. You may need to manually adjust brightness after waking the monitor or use third-party software for display control. |
