There could be several reasons why your Arzopa portable monitor keeps going black. Here are some possible causes and solutions:

Power-related issues

• If the monitor is not receiving enough power, it may turn black. This could be due to a faulty power adapter or a problem with the power cable. Check if the power adapter is properly plugged into the monitor and the power source. Try using a different power outlet or a replacement power adapter if possible.
• Arzopa portable monitor can be powered via a USB-C connection from a device like a laptop. If the laptop's USB-C port does not provide sufficient power, the monitor may turn black. In such cases, try using an external power adapter for the monitor.
  

• The connected device may have its own power-saving settings that cause it to turn off or go black after a certain period of inactivity so the monitor will do the same thing. Check the device's settings menu and look for options related to power-saving or sleep mode. You can adjust these settings to increase the time before it enters power-saving mode or disable it entirely if needed.
  

Connection problems

1. If the cable connecting the monitor to the source device (such as a laptop or a gaming console) is loose or damaged, it can cause intermittent blackouts. Check the HDMI, USB-C, or other connection cables to make sure they are securely plugged in at both ends. Try wiggling the cables gently to see if the monitor's display changes. If the cable is damaged, replace it with a new one.
2. Arzopa portable monitors can use a combination of cables for power and video signal. For example, a single USB-C cable may be used for both. If this cable is not working properly, it can lead to display issues. In such cases, try using separate cables for power and video. For example, HDMI for video signal, USB C for power.

• The source device may have incorrect display settings that are not compatible with the Arzopa portable monitor. For example, if the resolution or refresh rate set on the source device is not supported by the monitor, it may cause the monitor to go black. On a laptop, you can usually access the display settings by right-clicking on the desktop and selecting "Display settings" (on Windows) or going to "System Preferences > Displays" (on Mac). Try adjusting the resolution and refresh rate to values that are known to be supported by the monitor.

Monitor hardware issues

• The backlight of the monitor may be failing, which can cause the screen to go black. This could be due to a manufacturing defect or wear and tear over time.
• Similarly, a problem with the display panel itself, such as a damaged pixel or a connection issue within the panel, can lead to blackouts. In some cases, these issues may require professional repair.

• If the monitor is overheating, it may shut down or go black to protect itself. This could be due to poor ventilation around the monitor or a malfunctioning cooling system. Make sure the monitor is placed in a well-ventilated area and not covered by any objects that could block airflow. If the problem persists, it may indicate a more serious issue with the monitor's cooling mechanism and may require professional attention.
