HDMI 2.1 Dual 4K144Hz KVM Switch Gaming Dock for 2 PCs & 2 Monitors, w/ ADI Chip, EDID, VRR, FVA, ALLM, and Dynamic HDR

• 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:

The HKS202-M24 models support HDMI2.1 protocol, with a maximum bandwidth of up to 48Gbps.

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.

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 HKS202-M24 is the [Right Ctrl]. If you need to use a different trigger key, please customize the hotkey settings accordingly.

The HKS202-M24 models 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.

• 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.

• 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.

For HKS202-M24 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.
