Adder AV4PRO-DVI-DUAL-US – 4-Port Dual-Head DVI KVMA Switch

Product Overview

The Adder AV4PRO-DVI-DUAL-US is a 4-port dual-head DVI KVM switch that lets one operator control four computers from a single console with two high-resolution displays, USB 2.0 peripherals and analog audio. Part of the AdderView 4 PRO MultiScreen family, this dual-monitor KVMA switch supports dual-link DVI resolutions up to 2560x1600, making it suitable for film production at 2K and detailed imaging work. With USB True Emulation for instantaneous hotkey switching, it is a dependable desktop KVM switch for multi-monitor control positions.

Product Description

The AV4PRO-DVI-DUAL connects four computers through eight DVI-I inputs (two per machine), four USB 2.0 Type-B ports and four 3.5mm audio inputs, presenting them to a single console with two DVI-I display outputs, USB peripherals and speakers. Dual-link DVI capability supports demanding resolutions including 2K (2048x1080) for film work and WQXGA (2560x1600), while the DVI-I connectors also accommodate high-definition analog sources.

Adder's USB True Emulation continuously emulates connected HID devices to every computer, so hotkey and three-button-mouse switching is instantaneous and reliable, and specialty devices — graphics tablets, jog shuttles, joysticks — behave exactly as if directly connected. Two additional transparent high-speed USB 2.0 ports handle printers, scanners and other peripherals, and independent peripheral switching lets the operator type on one computer while a USB device stays attached to another. Audio follows the same independent-switching logic.

Channel selection options include keyboard hotkeys, a three-button mouse, front-panel buttons or the optional RC4 remote via the Options port, which also supports ASCII control codes, unit linking for additional video heads, and firmware upgrades. Extended DDC EDID profiling keeps graphics cards optimized for the attached screens, and the fanless metal chassis runs silently at the desk or in a rack with the optional RMK kit.

Frequently Asked Questions

How many displays does each computer need to drive?
Each computer connects two DVI-I outputs to the switch, which routes them to the two console displays. Single-output machines can still be connected but will drive one screen.

Will my graphics tablet or jog shuttle work through the switch?
Yes. USB True Emulation presents HID devices to every computer continuously, so tablets, jog shuttles and joysticks behave as if directly attached.

Can I keep a USB peripheral on one computer while typing on another?
Yes. Independent peripheral switching routes the keyboard/mouse, the transparent USB ports and audio to different computers at the same time.

How do I switch channels?
Keyboard hotkeys, three-button mouse, front-panel buttons, or the optional RC4 remote; the Options port also accepts simple ASCII codes from a control system.

Can multiple units be combined for more screens?
Yes. Units can be linked through the Options port to build multi-video-head switching systems beyond two displays.

Is it rack mountable?
Yes, with the optional Adder RMK rackmount kits sold separately; contact Creation Networks for the correct kit for your installation.
