Detailed Function Description
- HK4400_B integrates four-channel HDMI KVM seamless fast switching. One console set — monitor, keyboard and mouse — can centrally control four computers while USB 3.0 peripherals and audio follow the selected source.
- 4×4 HDMI Matrix Switcher | 4K30 with Audio Embedding & De-embedding.
- Supports matrix cross-switching and four-screen video wall operation. Users can switch freely between a 2×2 spliced large display, independent multi-screen display, or mixed display layouts.
- Scene save and quick recall functions improve layout switching efficiency in meeting rooms, showrooms and control rooms.
- The Web control interface supports input/output switching, video wall mode setup, scene recall and system management.
- RS232, TCP/IP, IR, hotkey, app and front-panel control make it easy to integrate with central control systems or operate independently.
- Designed for small-to-medium professional AV environments, providing a lightweight, efficient and economical alternative to complex distributed KVM over IP or high-end 4K60 systems.

⚠ Deployment Notes
- For best image quality and stability, the total HDMI cable length, including input, output and relay segments, is recommended not to exceed 10 meters.
- For long-distance cabling, use HDMI extenders, HDBaseT or AVoIP systems.
- Do not use uncertified switchers, splitters or adapters, as they may affect compatibility and stability.
- When used with other equipment, confirm compatibility in advance to avoid unnecessary installation issues.
- Use the original dedicated KVM extender whenever possible. Avoid mixing third-party extension devices to prevent protocol mismatch, signal interruption or control delay.
