From 4K to 240Hz — It Just Works
Three Displays, More Flexible Modes
EDID Emulation — Stable Screens, No Surprises
Built-in Shared Docking Station
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 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.
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.
Easy Switching, 4 Ways
Independent USB & Audio Focus Lock
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
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.
FAQs
What to do when the monitors are displaying a black screen after connecting all devices to the KVM?
Connect the each computer directly to the monitor, bypassing the KVM switch, to check if they work properly. If any one of them can not display correctly, the problem may be with the computer port, the monitor port, or the cable between them. Try replacing the monitor or the cables connected to the KVM to troubleshoot.
If the problem only occurs when switching to a specific input source, try to swap the port connection between this PC and another working PC, to observe if the monitor can display properly in the configuration.
If none of the above steps solve the problem, in addition to the damage of the KVM itself, we may consider the following technical compatibility reasons:
- It might be the compatibility issue between the KVM and the converter devices/ dock stations in connection, resulting in video signals can not be smoothly transmitted to the monitor to be displayed.
- 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.
- Some monitors fail to communicate with the KVM via Aux, leading to the inability to detect the monitor connection.
If you encountered any problem mentioned above, we sincerely hope to assist you in troubleshooting to improve your experience with our product. Please do not hesitate to contact us and share the issues you’ve encountered and we will collaborate with our technical team to resolve your concerns after obtaining relevant information.
What refresh rates does this KVM support in 4K resolutions？
The HKS203-P24 models support HDMI2.0 protocol, with a maximum bandwidth of up to 18Gbps.
- 3840x2160@60Hz 8bit
- 3440x1440@100Hz 8bit
- 2560x1440@120Hz 8bit
- 1920x1080@240Hz 8bit
The user manual inside the box does not contain detailed information on how to operate the KVM Switch, where to get the instructions?
In order to be environmentally friendly and to reduce the use of paper and hard brushing film, we have uploaded the detailed instructions in electronic form to the Support Centre of TESmart official website, you can scan the QR code on the user manual included in the box (the second page and the back cover) to get access to the detailed operation instructions.
What to do if the hotkey switching is not working?
Please make sure the keyboard is connected to the dedicated keyboard port on the front panel (with keyboard and mouse marks).
The default hotkey for HKS203-P24 is the [Right Ctrl]. If you need to use a different trigger key, please customize the hotkey settings accordingly.
The HKS203-P24models support 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 models of keyboard and mouse 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 front 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 port on the front panel charge the computer connected? If so, what’s the power output?
The USB 3.2 Gen 1 port 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.
Why is there no sound when an audio device is plugged into the 3.5mm audio port of the KVM?
For HKS203-P24 model, they both feature an integrated microphone and L/R audio output port, and the audio signals from the audio interface are transmitted through the USB channel. Please confirm if the selected the playback device for audio has been set to "USB Audio" channel.
