The 8K60 HDMI 2.1 2x1 KVM Switch is designed to deliver seamless control of two computers using a single keyboard, mouse, and display without sacrificing performance. Supporting ultra-high resolutions up to 8K@60Hz, 4K@120Hz/144Hz, and 1080p@240Hz, this switch is ideal for professional AV environments, high-refresh gaming setups, and advanced workstations that demand uncompromised video quality and fast switching.

Equipped with USB 3.0 peripheral sharing, multiple control methods, and advanced HDMI 2.1 features, the switch ensures a smooth, zero-latency experience. With broad operating system compatibility and true plug-and-play operation, it integrates easily into professional workflows, control rooms, studios, and high-performance desktop environments.

Features In-Depth

Built around HDMI 2.1 architecture, this 2x1 KVM switch supports a 40Gbps video bandwidth, ensuring stable transmission of ultra-wide and high-refresh video formats. Full support for HDR, HDR10, HDR10+, Dolby Vision, and HLG preserves accurate color reproduction and contrast, while HDMI 2.1 gaming features such as VRR, ALLM, QMS, QFT, and SBTM deliver smooth, tear-free visuals with minimal latency.

The integrated USB 3.0 switching engine enables shared access to keyboards, mice, storage devices, webcams, and other peripherals at speeds up to 5Gbps. Each HDMI input is equipped with independent EDID emulation, maintaining stable resolution and preventing display re-handshaking during source switching. Advanced hardware and firmware design ensure zero video and audio latency, making it suitable for live production, mission-critical control, and fast-paced interactive environments.

For flexible control and automation, the switch supports front-panel buttons, keyboard and mouse hotkeys, IR remote control, and RS-232 ASCII commands. A built-in virtual interaction function automatically wakes connected PCs from standby, significantly reducing switching time. With support for Windows, macOS, and Linux and no drivers required, the unit delivers reliable, plug-and-play performance in both professional and enthusiast applications.

Content Creation / Post-Production

The BG-8K-KVM21A’s full 48Gbps HDMI 2.1 bandwidth ensures uncompressed 8K and high-frame-rate 4K signals are delivered without chroma subsampling or visual artifacts, preserving image fidelity throughout the workflow. Support for RGB and YCbCr 4:4:4, 12-bit color depth, and advanced HDR formats allows editors and colorists to evaluate accurate color, contrast, and luminance in real time.

EDID emulation per input maintains consistent resolution and refresh settings for each workstation, eliminating display renegotiation when switching systems. This results in uninterrupted timelines, stable grading sessions, and precise visual monitoring across multiple production machines.

Professional AV / IT / Control Rooms

Designed for operational environments, the 2x1 KVM architecture enables seamless control of two computers through a single workstation without compromising video or USB performance. Near-zero video and USB latency ensures instant operator response, while USB 3.0 peripheral sharing supports high-speed devices such as cameras, storage, and control interfaces.

Virtual interaction technology minimizes downtime by automatically waking connected systems during switching, improving efficiency in time-sensitive operations. With RS-232 and IR control, the unit integrates easily into centralized control systems for automated and dependable system management.

High-End Gaming / Simulation

The BG-8K-KVM21A supports 4K at 120Hz/144Hz and 1080p at 240Hz, delivering smooth, ultra-responsive visuals required for competitive gaming and simulation environments. Advanced HDMI 2.1 features such as VRR, ALLM, QFT, and QMS reduce latency, eliminate screen tearing, and optimize frame timing for fluid motion.

Near-zero-latency switching ensures immediate input response when moving between systems, maintaining immersion and precision. Multiple control options - including hotkeys, front-panel buttons, and IR remote - allow fast, intuitive switching without disrupting gameplay or simulations.
