HDMI 2.1 KVM Switch – Overview

An HDMI 2.1 KVM switch is a single device that allows users to control multiple computers using one set of peripherals, typically a keyboard, mouse, and display. What sets HDMI 2.1 KVM switches apart from HD or 4K supported models is their ability to support ultra high resolutions and refresh rates, including up to 8K at 60Hz and 4K at 120Hz.

As high performance PCs, gaming systems, and professional workstations continue to adopt HDMI 2.1 graphics outputs, the demand for reliable, cost effective 8K capable infrastructure has grown rapidly. HDMI 2.1 KVM switches are designed to meet this need, providing seamless switching without sacrificing image quality, responsiveness, or peripheral performance.

Below, we’ll take a look at several HDMI 2.1 KVM switch options from BZBGEAR and explore how they fit into real world workflows or just situations that need them.

Standard 2×1 and 4×1 HDMI 2.1 KVM Switches

The BG-8K-KVM21A and BG-8K-KVM41A are designed to let users view and control two or four PCs using a single HDMI display and shared USB peripherals.

How They Work

Each PC connects to the KVM switch using:

• HDMI for video and audio
• USB (host connection) for keyboard, mouse, and peripheral control

On the output side, the KVM switch provides dedicated USB ports for shared peripherals such as:

• Keyboard and mouse
• Webcam
• External storage
• Other USB accessories

Once connected, all peripherals can be instantly switched between PCs.

Switching Methods

Users can change active systems using:

• Keyboard hotkeys
• IR remote control
• Front panel push buttons

This flexibility makes switching fast and intuitive, whether you prefer keyboard shortcuts or physical controls.

Common Use Cases

Standard HDMI 2.1 KVM switches are ideal for workflows where performance and separation matter, such as:

• Gaming setups where one PC is dedicated to gaming and another to streaming or chat. When gaming professionally or entertaining a live audience, using only one PC to game, stream, interact, and do backend work is risky business…. 
• Post-production environments, separating editing, rendering, and asset management systems. The HDMI 2.1 support also helps ensure color accuracy and smooth processing. If it isn’t perfect in the end, it’ll be close! 
• Engineering and software development, keeping test machines and main workstations isolated. You can never be too careful with big projects. The advanced image processing of these units is also ideal for these applications. 
• Home offices where a work PC and personal PC share the same desk setup. The days of having to unplug PC1 to connect PC2 are over; just push a button or do a quick keyboard command to switch. 

Overall, by avoiding the need to run multiple heavy tasks on a single system, users benefit from better performance, cleaner organization, and a more efficient workspace.

2×2 Dual Monitor HDMI 2.1 KVM Switch

The BG-8K-KVM22MA is a dual monitor HDMI 2.1 KVM switch built for more advanced desktop environments. It supports two HDMI outputs, enabling flexible multi-display workflows while maintaining full HDMI 2.1 performance.

Dual Mode Operation

This model supports two primary operating modes:

1. Single-PC Dual-Monitor Mode
   • One computer outputs to two HDMI 2.1 displays
   • Ideal for expanded desktops, timelines, dashboards, or multitasking
2. Dual-PC Display Mode
   • Two PCs can each be displayed simultaneously across two monitors
   • Easily switch control of peripherals between systems

Ideal Applications

The BG-8K-KVM22MA is well suited for:

• Creative professionals working with dual-monitor editing or color-grading setups
• Financial and data professionals managing charts, feeds, and dashboards
• Control rooms and technical environments requiring multiple live views
• Power users who rely on dual displays for productivity and workflow efficiency

With HDMI 2.1 bandwidth, users can maintain high refresh rates, HDR support, and ultra-high resolutions across both monitors without compromise.

Why Choose an HDMI 2.1 KVM Switch?

Compared to HDMI 2.0 based solutions, HDMI 2.1 KVM switches offer:

• Support for 8K60 and 4K120
• Higher bandwidth for smoother motion and lower latency
• Better compatibility with modern GPUs and next generation systems
• A future-proof solution as displays and computers continue to evolve. And they’re evolving faster than ever

Whether you’re building a gaming station, a professional workstation, or a shared control environment, HDMI 2.1 KVM switches provide a clean, efficient way to manage multiple systems without clutter or performance loss.
