Triple 8K60 is only as good as its stability
From 8K to 240Hz – It just works
Triple 4K144 HDR VRR
Three displays, more flexible modes
No flickering. No restarts. No black screen.
Thanks to ADI 7674 decoding and advanced EDID emulation, this KVM ensures stable multi-monitor output – even with high bandwidth.
Why this KVM is different:
• ADI 7674: Industrial-grade HDMI 2.1 decoding
• Intelligent EDID: Signal always remains active, no loss of display
• Supports VRR/FVA/ALLM for smooth, stutter-free gaming
• Ideal for high-FPS gaming and high-performance creative workflows
Designed for smooth gameplay, creative workflows, and crystal-clear visuals. With HDMI 2.1 and DSC, our KVM supports extreme resolutions and high refresh rates on a wide variety of displays.
Each HDMI 2.1 output theoretically supports up to:
• 7680×4320 (8K UHD) — 60Hz (DSC)
• 5120×1440 (32:9 Ultra-Wide) — 120 Hz (DSC)
• 3840×2160 (4K UHD) — 240 Hz (DSC)
• 3440×1440 (21:9 Ultra-Wide) — 144 Hz
• 2560×1440 (QHD) — 240Hz
• 1920×1080 (FHD) — 240Hz
Faster switching. Stronger signal. Smoother images.
• Fast switching in 1–3 seconds: No dropouts, no resets
• Signal always active: No connection interruptions when switching
• VRR/FVA/ALLM supported: Smooth, low-latency gaming
• Triple 4K@120Hz HDR (12-bit): Impressive clarity and colors
• Up to 4K@144Hz 165Hz via DSC: Perfect for fast-paced action games
Powered by ADI HDMI 2.1 decoding – amplifies weak signals and ensures seamless multi-monitor stability
• Mode 1: One PC on all 3 monitors (Extend or Mirror)
Use one computer to display content on all three screens – either as a widescreen workspace for increased productivity or mirrored for demos and presentations. Configure via your PC's display settings.
• Mode 2: Two PCs distributed across 3 monitors
Assign two monitors to one PC and the third to another – or combine them flexibly as needed. Ideal for monitoring, hybrid PC setups, or task separation (e.g., development vs. testing). The focus can be conveniently switched via hotkey.
EDID Emulation – Stable screens, no surprises
Built-in shared docking station
Easy switching – 4 ways to choose from
Independent USB & audio focus lock
Dedicated K&M-Ports with dual-mode support
Switching between displays shouldn't mess up your desktop. Our integrated EDID emulator ensures your layout stays exactly as you left it.
• No more misplaced symbols
Retains the position of desktop icons and the size of open windows when switching inputs.
• Flicker-free switching
Prevents screen dropouts and flickering caused by re-initializing the display.
• Smoother multitasking
Maintains visual consistency between workstations and monitor setups.
✅ With TESmart EDID emulation: Your display remains stable and unchanged – even after switching channels.
⚠️ Without EDID emulation: icons move, window sizes change, and the screen flickers after each change.
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 and workflow:
• Custom hotkey switching – Quick keyboard shortcuts for power users
• Front button operation – Easy, direct access at any time
• IR remote control – Convenient control from the other end of the desk
• Mouse wheel toggle – Double tap for instant toggling
Whether at work, gaming, or giving presentations – choose the method that suits you best.
Switch displays without interrupting your USB devices or audio connection.
This KVM allows you to independently lock the focus of USB 3.0 and L/R audio – so that headsets, webcams or external drives remain connected to the current PC, even during screen switching.
Highlights:
• Lock USB and audio focus separately
• Avoid interruptions to calls or devices
• Lock status remains even after restarting
✅ Ideal for meetings, streaming and multitasking
⚠️ USB focus ≠ keyboard & Mouse focus – they are switched separately.
To improve keyboard and mouse compatibility – especially when switching hotkeys – we have developed two special connection modes:
• Pass-through mode (recommended)
Direct routing to the PC. Supports advanced drivers, macros, high-DPI mice, and multifunctional input devices. Ideal for gaming, design, and professional workflows.
• Legacy emulation mode
Ensures universal compatibility and stable hotkey functionality on most systems. Best suited for office applications or when experiencing driver issues.
✅ Hotkey commands only work if your keyboard is connected to the dedicated K&M-Port is connected.
⚠️ Emulation mode disables driver-based software and advanced features.
⚠️ Bluetooth keyboards and mice are not supported.

FAQs
Why can't my computer use Wi-Fi after connecting to the KVM?
The KVM switch has an integrated network card that is enabled by default. Computers may prioritize the wired connection. If you want to use Wi-Fi instead of the KVM's wired connection, you can:
Disable the KVM's integrated network card for the selected computer:
- Switch to the desired computer using [Right Ctrl] → [Right Ctrl] → [1]/[2].
- Press [Right Ctrl] → [Right Ctrl] → [F4] to turn off the integrated network card.
- Note: The buzzer sounds twice when activated and once when deactivated.
Disable the USB network adapter in the computer settings (example Windows 11):
Method 1: Advanced network settings
- Press [Win + I] to open Windows settings.
- Go to Network & Internet → Advanced network settings.
- Look for the adapter called Realtek USB GbE Family Controller in the list.
- Click on Deactivate.
Method 2: Device Manager
- Press [Win + X] and select Device Manager.
- Expand Network Adapters and search for Realtek USB GbE Family Controller.
- Right-click and select "Disable device".
Using one of the two methods, your computer prioritizes Wi-Fi while remaining connected to the KVM switch.
How can the fan speed be adjusted?
The KVM switch supports four fan modes. Each mode is indicated by the number of beeps from the buzzer. The default mode is Mode 2. To set the fan mode: Press [Right Ctrl] → [Right Ctrl] → [F3] to cycle through the modes.
- Fan mode 1: The fan is deactivated. The buzzer sounds once.
- Fan mode 2: The fan operates automatically based on the current temperature. The buzzer sounds twice.
- Fan mode 3: The fan runs continuously at low speed. The buzzer sounds three times.
- Fan mode 4: The fan runs continuously at high speed. The buzzer sounds four times.
Does this KVM support Dolby Vision?
Yes. The HDK202-M24 supports HDMI 2.1, HDR10 and Dolby Vision.
Can this KVM 4K@144Hz- oder Supports 8K monitors?
Yes. The HDK202-M24 supports HDMI 2.1 and resolutions up to 8K (4320p) @60Hz. It is also backward compatible with 4K (2160p) @60/120/144Hz.
Does the KVM support both Mac and Windows environments?
Yes. The HDK202-M24 is compatible with a wide range of operating systems, including Windows, macOS, Unix, and Linux-based systems such as Debian, Ubuntu, Fedora, and Raspbian (including support for Raspberry Pi). It works in mixed operating system environments without additional configuration.
Why is my audio device not working?
Connection requirements
The KVM switch's audio function requires proper USB connections. Please ensure your computer is securely connected to the KVM via the designated USB-A to USB-B ports to guarantee reliable audio data transmission.
Sound settings on the computer
With 3.5 mm jack connection: In your computer's sound settings, select "USB Audio" as the default output device.
With USB 3.0 connection: Select the appropriate USB audio output, e.g., "USB Audio Device" or "USB Headset", depending on your system's display.
If no sound is output via the 3.5 mm output even after correct adjustment, we recommend using a USB sound card (USB to 3.5 mm adapter) to improve compatibility and ensure proper audio output.
Why are my keyboard and mouse not working properly?
Common symptoms:
- Keyboard shortcuts (hotkeys) are not working.
- Keyboard input is unresponsive or delayed
- Keystrokes get stuck or are registered twice
- Mouse movements lag or stutter.
Recommended solutions:
Try switching to legacy emulation mode to improve compatibility with a wider range of keyboards and mice:
- Press [Right Ctrl] + [Right Ctrl] + [F2].
If the problem persists, please contact our technical support team at support@tesmart.com, to receive expert support and guidance on troubleshooting and resolving the problem.
Does the KVM switch support firmware updates?
