How to Fix AOC USB Monitor not Working

AOC produces low power consumption and low-cost monitors. Their monitors are mostly powered by USB and can run directly connected to your laptop or desktop. However, users have reported multiple issues over the years. The issues range from frequent display disconnection to zero display from the monitor.

Some of the solutions provided online mention changing the proprietary USB cable that comes with the monitor, while others advise updating display drivers.

Use Short Cable for Less Power Interruption

A large number of users reported that the AOC monitors either turned on and worked for a few seconds or they did not show any display at all. Moreover, this issue was faced by a majority of Microsoft Surface users. The solution provided and verified by many users is to use a different cable than the one accompanying the monitor. The reason being that these USB cables are longer and provide more interruption in the power flow. Furthermore, USB hubs also did not generate enough power with the provided cable. Any normal charging cable for a phone depending on the port on the monitor (USB 2.0 or USB 3.0) will work.
