This 4" USB Monitor is a display screen designed for use inside PC cases or on desktops as an RGB screen. It has a high-resolution 720 x 720 LCD for a colourful and vivid display, a dual USB-C connector, a Micro SD slot, and a tough CNC aluminium alloy case.

This monitor supports NVIDIA and AMD discrete graphics cards and has cool functions such as music spectrum analysis and dynamic video backgrounds. It comes with self-developed software for easy theme management and various data monitoring without impacting computer performance. The screen connects via a single USB-C cable for both power and data.
