7. Troubleshooting (Q&A)

Q: Why does my monitor not turn on?

1. Check if the Type-C port of your device is a full-featured Type-C port that supports both power and signal transmission. If not, use an HDMI to Mini HDMI cable for video signal and a USB-C to USB-C cable for external power supply.
2. Insufficient power supply may be the cause. The monitor requires a minimum of PD 18W. For 2K 120Hz display, higher power consumption is expected, so an external power supply is recommended.
3. If the issue persists, contact customer support.

Q: It says "no signal", what to do?

1. When connecting with a USB-C cable, ensure your device supports USB3.1/Thunderbolt 3. If not, use a Mini HDMI to HDMI cable for signal transmission.
2. Always use the original cables provided.
3. Try connecting to another device. If it still fails, contact customer support for a replacement.

Q: Why does my monitor turn off when I turn up the brightness?

This is typically due to insufficient power supply. Increasing brightness increases power consumption. Ensure you are using an adequate external power supply.

Q: Abnormal conditions occurred (e.g., splash screen, spots, constant restarts).

1. This is generally caused by insufficient power supply. The monitor requires high power. Use the original cable included to power the monitor.
2. If using a mobile power bank, confirm it provides 30W or more. For power bank recommendations, contact support@uperfectmonitor.com.
3. If none of the above solutions work, try another device. If it still fails, contact customer support for a replacement.

Warm Tips:

• If the screen signal is poor or flickers, ensure you are using the provided adapter. Other adapters may provide insufficient voltage. If flickering persists, try a different HDMI cable.
• Verify that your PC/Laptop's Type-C port supports audio and video signal transmission (Thunderbolt 3). If not, a "Type-C to HDMI" adapter is required.
• If "No Signal" or "Power Saving Mode" appears, try reversing the Type-C cable head and reconnecting.
• The monitor defaults to power save mode. To disable, you need to manually turn it off in the OSD menu.
• The 18.4" portable monitor does not have a built-in battery or touchscreen function.

8. User Tips

• Optimal Viewing Angle: For best comfort and safety, place your monitor at or slightly below eye level. Avoid steep downward angles that may stress the stand, especially with larger screens.
• Safety Reminder: Due to the weight of the monitor, it is not recommended to place it above your head for your safety.
• Cable Management: Always use the provided original cables for stable connections and power delivery.
• Power Supply: Ensure sufficient power supply, especially when using high brightness or high refresh rates, to prevent unexpected shutdowns.
