Home Networking Network Switches StarTech VS221HD4KA 2-Port HDMI 4K Automatic Video Switch

StarTech VS221HD4KA 2-Port HDMI 4K Automatic Video Switch

Brand:
StarTech.com

The StarTech VS221HD4KA is a 2-port HDMI 4K automatic video switch that routes two HDMI sources to one HDMI display. Designed for boardrooms, classrooms, digital signage, commercial AV and other professional installations, it supports up to 3840 × 2160 at 30Hz, HDMI 1.4, HDCP 1.4, 5.1/7.1-channel audio and EDID emulation. Automatic, priority and manual switching provide flexible source management, while RS-232 and IR control support convenient operation. It is TAA compliant and backed by a 2-year warranty.

OVERVIEW

  • The StarTech VS221HD4KA is a professional 2-input HDMI 4K switch for sharing one monitor, projector or TV between two HDMI sources. It combines fast automatic switching, priority selection, manual control, EDID emulation and remote/RS-232 operation in a compact steel enclosure. Compatibility: HDMI 1.4/HDCP 1.4 sources and displays. Model comparison: this model provides 2 inputs to 1 output; choose a matrix switch when multiple outputs are required. 

USE CASES

  • Corporate boardrooms: Share one 4K display or projector between presentation computers and other HDMI sources.
  • Conference rooms: Allow multiple presenters to use the same display without physically reconnecting HDMI cables.
  • Classrooms: Switch between an instructor computer, media source or other HDMI equipment on a shared display.
  • Digital signage: Use priority or automatic switching to manage multiple HDMI content sources while retaining 4K capability. 
  • Healthcare facilities: Share compatible HDMI displays between designated multimedia or presentation sources.
  • Hotels and hospitality: Centralize two HDMI sources for a shared television or presentation display.
  • Retail environments: Switch between HDMI media sources for commercial displays and promotional content.
  • Trade-show installations: Provide convenient source selection for a shared 4K display or projector.
  • AV test benches: Connect two HDMI source devices to a single reference display for equipment testing and troubleshooting.
  • Home theater installations: Share a 4K television between two HDMI entertainment sources while retaining remote source selection.

KEY FEATURES

  • Two HDMI inputs with one HDMI output: Allows two HDMI source devices to share one display, reducing the need to manually reconnect cables when users or content sources change. 
  • 4K Ultra HD at 30Hz: Supports 3840 × 2160 resolution for detailed presentations, signage and multimedia content while retaining compatibility with lower resolutions. 
  • Fast automatic switching: Detects the latest connected HDMI source and switches to it automatically, reducing manual intervention during presentations and shared-display workflows. 
  • Priority switching: Lets one HDMI input receive source priority, which is useful when a designated source should remain preferred in applications such as digital signage. 
  • Manual front-panel switching: Provides direct source selection from the device, giving installers and operators a straightforward fallback when automatic switching is not preferred. 
  • EDID emulation and copy support: Communicates display settings such as resolution and refresh rate to improve source-display compatibility and simplify installation.
  • 5.1 and 7.1 surround audio: Supports multichannel HDMI audio, allowing compatible AV installations to retain immersive sound alongside video switching. 
  • IR remote control: Enables operators to change HDMI sources without accessing the switch directly, useful when the unit is positioned away from the user. 
  • RS-232 serial control: Provides an integration option for compatible control systems and professional AV environments requiring centralized source management. 
  • TAA compliance: Helps organizations meet procurement requirements that specify Trade Agreements Act-compliant equipment. 
  • Steel enclosure: Provides a durable housing for fixed commercial and professional AV deployments. 
  • Plug-and-play operation: No driver installation is required, helping reduce deployment complexity for compatible HDMI equipment.
