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)
FAQs
What to do when the monitor displays a black screen after connecting all devices to the KVM?
- Make sure to use the included power adapter.
- Make sure to connect the thunderbolt 3 or thunderbolt 4 port on your computer, or a USB-C port that supports DP Alt mode.
- Try connect the computer directly to the monitor using the output HDMI cable, to check if it can display properly. If no, the issue could lie with the output HDMI cable or the monitor itself. In this case, please try to replace the output cable or the monitor to troubleshoot.
- If none of the above steps solve the problem, we may also consider the following technical compatibility reasons:
1) It might be the compatibility issue between the KVM and the converter devices/ dock stations/ computer itself in connection, resulting in video signals can not be smoothly transmitted to the monitor to be displayed.
2) The EDID data of certain monitors is quite unique, causing the KVM to read the EDID data abnormally, which in turn affects the display performance of the monitors.
3) Some monitor models fail to communicate with the KVM via Aux, leading to the inability to detect the monitor connection.
What refresh rate does the KVM support in 8K and 4K resolution?
CKS201-M23 supports DP 1.4 protocol and DisplayPort Alternate Mode (DP Alt Mode).
- 7680x4320@60Hz 8bit
- 3840x2160@60Hz 8bit
- 3840x2160@120Hz 8bit
- 3840x2160@144Hz 8bit
What to do if laptop indicates that the charging power is too low?
- Currently the Input A port on the CKS202-P23 supports charging at around 36W; the main reason for limiting the charging power to this standard is due to a combination of factors such as heating concerns that may affect its lifespan. If more charging power needed, you can consider another model as same series, the HDC202-P23, which will provide 60W charging power for the Input 1 port; in the future, we will also release the Plus version of CKS202-P23, which will upgrade to 60W charging power.
What to do if the hotkey switching is not working?
- Please make sure the keyboard is connected to the dedicated keyboard port on the rear panel (with keyboard and mouse marks).
- The default hotkey for CKS201-M23 is the [Right Ctrl]. If you need to use a different trigger key, please customize the hotkey settings accordingly.
- The CKS201-M23 model supports both pass-through mode and legacy emulation mode for keyboard and mouse control. For pass-through mode, it features good compatibility with the mainstream keyboards and mice on the market. However, with the iterative upgrading of the keyboards and mice, it is inevitable that there will be some special keyboards and mice which may have potential compatibility issues with our KVM, therefore, to get better compatibility experience, it is available to turn to legacy emulation mode.
- If you encounter some issues with the keyboard and mouse in pass-through mode, please connect a basic keyboard to the dedicated keyboard port on the rear panel of the KVM and switch to legacy emulation mode using the hotkey combination [Hotkey + Hotkey + F2]. This mode theoretically enhances the compatibility mode between the keyboard and mouse and our KVM. Once set successfully, you can reconnect your original keyboard and mouse instead and continue to use them.
What are the differences between the keyboard and mouse pass-through mode and legacy emulation mode, and how to switch between them?
- Legacy emulation mode provides the PC with preset basic keyboard and mouse data information, ensuring basic functionality while improving compatibility theoretically. This means that the computer connected will not be able to recognize the actual keyboard and mouse specification, and the control software of keyboard and mouse will not work. If the keyboard and mouse function properly in pass-through mode, it is recommended to maintain pass-through mode.
- The default keyboard and mouse control mode is pass-through mode. You can switch between them using the hotkey combination [Hotkey + Hotkey + F2]. After pressing the hotkey, two beeps is emitted to indicate entry into legacy emulation mode, while one beep is emitted to indicate entry into pass-through mode.
Can the USB 3.2 Gen 1 ports on the front panel charge the computer connected? If so, what’s the power output?
- The USB-A and USB-C ports on the front panel indeed feature a built-in charging module that supports charging your phone, tablet, and other mobile devices but not the computer connected, with a maximum output power of 7.5W.
- It is designed under the BC1.2 protocol and the voltage and current can be automatically adjusted to match the specification of the device to be charged, ensuring safe charging.
Can the input USB-C ports on the rear panel charge the computers connected? If so, what’s the power output?
Yes, it supports charging your laptops connected to Input 1 and Input 2 on the rear panel of the KVM with PD protocol with the charging power of 60W, which can meet the daily office requirements.
