TRADE VISION 102 4 PORT

A compact 4-port HDMI multi-display device, typically designed to either split one HDMI source to four screens or switch between four HDMI sources. It supports 1080p resolution, with higher-end models reaching 4K, and often includes a metal casing for durability.

The TRADE VISION 102 likely falls into the “1 in 4 out” or “4 in 1 out” category of HDMI management devices.

If it is a Splitter (4 Port Output), it is designed to display the same image on four separate screens simultaneously. It is often housed in a compact plastic or metal chassis and supports features like 3D video pass-through and HDCP 1.4 compliance. This setup is useful for digital signage, retail displays, or conference rooms.

If it is a Switch (4 Port Input), it allows you to connect up to four HDMI sources (e.g., laptop, set-top box, console) to a single TV. A key feature is often Auto-Switching, where the device automatically jumps to the newly powered-on device, saving you from manually changing inputs.
