A 1U display refers to a flat-panel monitor or screen that is designed to fit into a standard 1U (one rack unit) space in a server rack. A 1U size KVM (Keyboard, Video, Mouse) switch is a compact KVM switch that occupies a single rack unit in a server rack.
1U displays are often used in conjunction with KVM switches or as standalone monitors to provide real-time visuals of server status, system performance, and other critical data.
1U size KVM switch typically supports multiple ports, enabling the connection of various systems while offering features such as hotkey switching, support for high-resolution video, and sometimes integrated USB or serial ports for additional device connectivity.
