Black Box Corporation KV9704A DT Series 4-Port DisplayPort USB KVM Switch

Four-Port DisplayPort KVM for Multi-Computer Control

The Black Box DT Series KV9704A lets one DisplayPort monitor, keyboard, mouse and up to four USB peripherals switch between four connected computers. Front-panel push buttons and hotkey commands select the active system instantly. Autoscan mode cycles through ports automatically. No driver installation is required for basic keyboard and mouse operation.

Check DisplayPort outputs and USB peripheral count

Verify that each of the four source computers provides a DisplayPort video output and a USB port for the KVM link. Confirm the single monitor accepts a DisplayPort signal at the resolution and refresh rate you need. Ensure the total number of USB devices you plan to share does not exceed four, as the switch supports up to four different USB peripherals across all connected systems.

Replaces manual cable swapping or smaller KVMs

This unit replaces the hassle of physically moving DisplayPort and USB cables when shifting between four workstations. It also upgrades from a two-port KVM when a fourth computer is added to the desk. The jump is worth it when daily workflow demands instant, driver-free switching across four systems with shared USB accessories and a single DisplayPort display.
