Easy Switching, 4 Ways
Independent USB & Audio Focus Lock
Auto Detect Mode — Smart Switching, Zero Hassle
Dedicated K&M Ports with Dual-Mode Support
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
No need to manually switch inputs — the KVM detects and switches to the active device as soon as it powers on.
- Intelligent Signal Detection
Automatically senses new signal input and switches focus to the latest active PC. - Hands-Free Operation
Ideal for setups with always-on desktops and occasional laptop use. - Seamless Experience
Minimizes delay or interruptions when waking devices or switching between systems.
✅ Example: When PC4 is powered on, the display switches to it automatically — no buttons needed.
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.

Yes. The HKS401-M24 supports HDMI 2.1 and resolutions up to 8K (4320p) @60Hz. It is also backward compatible with 4K (2160p) @60/120/144Hz.
Does This KVM Support Dolby Vision?

Does This KVM Support Adaptive-Sync on My Monitor?
Yes. The HKS401-M24 supports HDMI 2.1 and VRR (Variable Refresh Rate) functionality, and is compatible with both G-Sync and Free Sync technologies.
How to Adjust the Fan Speed?
The KVM switch supports four fan modes, each indicated by the number of beeps from the buzzer. The default mode is Mode 2.
Adjusting the fan mode: Press [Right-Ctrl] → [Right-Ctrl] → [F3] to cycle through the modes:
- Fan Mode 1: Fan is turned off. The buzzer will beep once.
- Fan Mode 2: Fan operates automatically based on the current temperature. The buzzer will
beep twice. - Fan Mode 3: Fan runs continuously at low speed. The buzzer will beep three times.
- Fan Mode 4: Fan runs continuously at high speed. The buzzer will beep four times.
How Do I Switch USB Peripherals or Audio Device Independently?
By default, the KVM operates in Follow Mode, meaning connected USB 3.0 devices and audio
device automatically switch with the keyboard/mouse focus.
- To disable Follow Mode: Press [Right Ctrl] → [Right Ctrl] → [~] to toggle Follow Mode. Note: Enable it will trigger the buzzer to beep twice and disable it will trigger the buzzer to beep
once. - To switch USB 3.0 & audio focus independently:
After disabling Follow Mode, press [Right Ctrl] → [Right Ctrl] → [0] to synchronously switch the USB 3.0 and audio devices focus between the two computers.
Why Does It Automatically Switch to a Newly Connected Computer?
The HKS401-M24 features an Auto Detect Mode. When a new signal source is detected, the KVM switch will automatically switch the display according to the auto-detection logic. Function Details:
- Automatic switch to new device:
When a new active input device is connected to the KVM switch, the system will automatically switch to the newly connected input source. - Automatic switch to the next active source:
If the currently displayed input source is removed (e.g., the computer is turned off or disconnected), the KVM switch will automatically switch to the next input source that still has a signal. Note: Auto Detect Mode is enabled by default and can be toggled on or off using the [M] button on the infrared remote control.
Why Is My Audio Device Not Working?
- Connection Requirements
The audio function of the KVM switch relies on proper USB connections. Please ensure that your computer is securely connected to the KVM via the designated USB-A to USB-B ports for audio data to transmit reliably. - Computer Sound Settings
1) For 3.5mm jack Connection: Select “USB Audio” as the default output device in your computer’s sound settings.
2) For USB 3.0 port Connection: Choose the appropriate USB audio output, such as “USB Audio Device” or “USB Headset”, depending on your system's display.
If no sound is output through the 3.5mm jack even after selecting the correct settings, we recommend using a USB sound card (USB to 3.5mm adapter) to improve compatibility and ensure proper audio output.
