- Mode 2: Two PCs Across 3 Monitors
Assign two monitors to one PC and the third to another, or mix as needed. Ideal for monitoring, hybrid PC setups, or task isolation (e.g. dev vs. testing). Switch KM focus easily via hotkeys.

Built-in Shared Docking Station
Easy Switching, 4 Ways
Independent USB & Audio Focus Lock
Prevent Accidental Input – Even From Your Cat
Dedicated K&M Ports with Dual-Mode Support
Streamline your setup with a built-in docking station that keeps everything connected — no extra hubs required.
- USB 3.0 (5Gbps) — High-speed data for drives and peripherals
- Gigabit Ethernet (1000Mbps) — Stable, wired internet for all devices
- 3.5mm Headset Jack — Unified audio input/output for meetings and calls
A cleaner, more efficient workspace — ideal for work-from-home or shared desk environments.
Switching shouldn’t slow you down — we offer four seamless methods to suit any setup or habit:
• Custom Hotkey Switching — Fast keyboard shortcuts for power users
• Front Panel Button — Simple, direct access anytime
• IR Remote — Stay in control from across the desk
• Mouse Wheel — Tap twice for instant switching
Whether you're working, gaming, or presenting — choose the way that works best for you.
Switch displays without interrupting your USB devices or audio.
This KVM lets you lock USB 3.0 and L/R audio focus independently, so your headset, webcam, or external drives stay connected to the current PC — even while switching screens.
Highlights:
• Lock USB and audio separately
• Prevent call or device dropouts
• Lock state remains after reboot
✅ Ideal for meetings, streaming, and multitasking
⚠️ USB focus ≠ keyboard & mouse focus — they switch separately
Avoid unwanted inputs during meetings, presentations, or idle time. With one button, you can lock screen output, audio, and all control interfaces.
• One-Touch Lock
Freezes display, disables USB, audio, hotkeys, and IR control.
• PIN Unlock
Resume exactly where you left off by entering your custom password.
• Peace of Mind
Prevents accidental switching — ideal for homes with kids or pets.
✅ Hotkeys and remote controls are disabled while locked.
⚠️ To unlock, press the Lock button again and enter your PIN.
To improve keyboard and mouse compatibility — especially during hotkey switching — we designed two specialized connection modes:
• Pass-Through Mode (Recommended)
Direct passthrough to the PC. Supports advanced drivers, macros, high-DPI mice, and multifunction input devices. Ideal for gaming, design, and pro workflows.
• Legacy Emulation Mode
Ensures universal compatibility and stable hotkey functionality across most systems. Best for office or when driver issues occur.
✅ Hotkey commands only work when your keyboard is connected to the dedicated K&M port.
⚠️ Emulation Mode disables driver-based software and advanced features.
⚠️ Bluetooth keyboards/mice are not supported.
