Adder AV4PRO-DP Review

Adder AV4PRO-DP 4 port DisplayPort KVM switch USB audio 2560x1600 broadcast editing suite

A four-computer DisplayPort switch built for post-production and broadcast bays, giving one operator instant hotkey control over four DisplayPort machines with synchronized USB peripheral and audio switching.

Overview

The AV4PRO-DP switches DisplayPort video, USB 2.0 peripherals, and stereo audio together across four sources, so pressing a hotkey moves the keyboard, mouse, speakers and display all at once, important in edit bays where audio and video must stay in sync during source changes.

Build and Control

Adder targets broadcast and secure environments with the AdderView PRO line, and the AV4PRO-DP includes both physical front-panel buttons and an on-screen display for confirming which source is active, reducing the chance of an operator editing the wrong machine live.

Comparison to Alternatives

Against ATEN's CS1922 (2-port USB-C, up to 4096x2160@60Hz) and CS782DP (2-port DisplayPort with audio), the AV4PRO-DP trades port density up to 4 while ATEN's units push higher per-port resolution/refresh on fewer ports. Broadcast facilities that need four full DisplayPort sources with matched audio typically choose the Adder; desks needing only two 4K60 sources are better served by the ATEN CS1922.
