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
EDID Emulation — Stable Screens, No Surprises
Zero flicker. No resets. No black screens.
Powered by ADI 7674 decoding and advanced EDID emulation, this KVM ensures stable multi-monitor output even under high bandwidth loads.
Why it’s built different:
- ADI 7674: industry-grade HDMI 2.1 decoding
- Smart EDID: signal always-on, no display loss
- VRR / FVA / ALLM supported for smooth, tear-free gaming
- Ideal for high FPS gaming and critical creative workflows
Built for smooth gameplay, creative workflows, and ultra-clear visuals. With HDMI 2.1 and DSC, our KVM supports extreme resolutions and high refresh rates across a wide range of displays.
Each HDMI 2.1 output theoretically supports up to:
- 7680×4320 (8K UHD) — 60Hz (DSC)
- 5120×1440 (32:9 Ultra-Wide) — 120Hz (DSC)
- 3840×2160 (4K UHD) — 240Hz (DSC)
- 3440×1440 (21:9 Ultra-Wide) — 144Hz
- 2560×1440 (QHD) — 240Hz
- 1920×1080 (FHD) — 240Hz
Faster Switching. Stronger Signal. Smoother Frames.
- Fast Switching in 1–3 Seconds: No blackouts, no resets
- Signal Always-On: No disconnects during switch
- VRR / FVA / ALLM Supported: Tear-free, low-lag gaming
- Triple 4K@120Hz HDR (12bit): Stunning clarity and colors
- Up to 4K@144Hz / 165Hz via DSC: Built for fast-action games
Powered by ADI HDMI 2.1 decoding — boosts weak signals and ensures seamless multi-monitor stability
- Mode 1: One PC on All 3 Monitors (Extend or Mirror)
Use one computer to span across three screens — either as a wide desktop canvas for productivity, or mirror all screens for demos and presentations. Configure in your PC’s display settings. - 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.
Switching displays shouldn’t scramble your desktop. Our built-in EDID emulator keeps your layout exactly how you left it.
- No More Icon Mess
Preserves icon positions and window sizes when switching inputs. - Flicker-Free Switching
Eliminates screen blackouts and flicker caused by display reinitialization. - Smoother Multitasking
Maintain visual consistency across workstations and monitor setups.
✅ With TESmart EDID emulation: your display stays stable and unchanged — even after switching.
⚠️ Without EDID emulation: icons shift, windows resize, and screen flicker occurs after every switch.
Built-in Shared Docking Station
Easy Switching, 4 Ways
Independent USB & Audio Focus Lock
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
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.
