Adder AV4PRO-DP-US – AdderView 4 PRO DisplayPort USB KVM Switch

Product Overview

The Adder AV4PRO-DP-US is a 4-port DisplayPort KVM switch that lets a single operator control four computers from one high-resolution console with shared USB 2.0 peripherals and analog audio. Built around Adder's USB True Emulation technology, this professional KVMA switch delivers instantaneous, reliable hotkey switching between DisplayPort sources at resolutions up to 2560x1600 at 60Hz. It is engineered for desks where operators need fast, dependable multi-computer control without duplicate keyboards, mice, and displays.

Product Description

The AdderView 4 PRO DisplayPort connects four computers through full-size DisplayPort 1.1 and USB 2.0 (USB B) links, presenting them to a single console with one DisplayPort monitor, True Emulation USB HID ports, two transparent high-speed USB ports, and a 3.5mm audio output. Because USB HID devices are continuously emulated to every computer, channel changes are immediate and keyboards, graphics tablets, jog shuttles, and joysticks behave consistently across all four systems.

Video performance suits demanding desktops: 2560x1600 at 60Hz with 10 bits per color, 1920x1200 at 120Hz, or Full HD 1920x1080 at 60Hz with 12 bits per color, while an extended DDC EDID profile keeps each graphics card optimized for the connected screen. Independent peripheral selection allows the operator to type on one computer while a USB printer, scanner, or storage device remains attached to another — a practical advantage in edit suites and operations desks.

Channel selection is available from keyboard hotkeys, a three-button mouse, front panel controls, or the optional ADDER RC4 remote, and an RS232 options port supports remote switching, firmware upgrades, and unit linking for multi-head configurations. The fanless 1U metal chassis runs silently in quiet rooms. The US model includes a country-specific power cable.

Frequently Asked Questions

What resolutions does the AV4PRO-DP-US support?
Up to 2560x1600 at 60Hz with 10 bits per color, 1920x1200 at 120Hz, or 1920x1080 at 60Hz with 12 bits per color over DisplayPort 1.1.

Can I keep a USB device connected to a different computer than my keyboard?
Yes. Independent peripheral selection lets the keyboard and mouse follow one channel while the two transparent USB ports remain assigned to other computers.

How do I switch channels?
Via keyboard hotkeys, a three-button mouse, front panel controls, or the optional ADDER RC4 remote; ASCII commands through the RS232 options port are also supported.

Can multiple units be combined for multi-monitor computers?
Yes. Units can be linked through the options port to create a multi-video-head switching system.

Is special driver software required?
No. USB True Emulation works at the hardware level and is compatible with Windows, Linux, Sun OS, macOS, and all known operating systems.

What is included with the US model?
The switch ships with a power supply unit, a US power cable, and a quick start guide. Computer connection cables are ordered separately.
