From 4K to 240Hz — It Just Works
Two Display Modes, Two Ways to Work
EDID Emulation — Stable Screens, No Surprises
Easy Switching, 3 Ways
One switch, endless options. Whether for gaming, content creation, or multi-window workflows, our KVM handles a wide range of resolutions and refresh rates with ease.
Each KVM output supports up to:
- 3840×2160 (4K UHD) — 60Hz
- 3440×1440 (21:9 Ultra-Wide) — 100Hz
- 3840×1080 (32:9 Ultra-Wide) — 120Hz
- 2560×1440 (QHD) — 120Hz
- 2560×1080 (21:9 Ultra-Wide) — 165Hz
- 1920×1080 (FHD) — 240Hz
- Mode 1: One PC on Two Monitors (Extend or Mirror)
Extend your desktop across both monitors or mirror your display for presentations. Simply configure in your PC’s display settings — perfect for multitasking or dual-screen workflows. - Mode 2: Two PCs on Two Monitors
Display two computers side by side — one on each monitor. Use hotkeys to switch the KM focus between them. Ideal for hybrid setups (e.g. Mac + Windows), dev work, or live monitoring.
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.
Switching shouldn’t slow you down — we offer three seamless methods to suit any setup or habit:
- Hotkey Switching — Use fixed key combos for quick source changes
- Front Panel Button — Simple, direct access anytime
- IR Remote — Stay in control from across the desk
Whether you're working, gaming, or presenting — choose the way that works best for you.
Independent USB & Audio Focus Lock
Prevent Accidental Input – Even From Your Cat
Dedicated K&M Ports with Dual-Mode Support
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.
⚠️ Legacy Emulation Mode available via firmware update (Prime 23 series)
