HDK202-P23 (Previously HDK0202A2U) FAQ

Pre-sales FAQ:

  1. Q: How do I connect my devices to the HDK202-P23?

A: There are two KVM cables (each consisting of an HDMI cable and a USB cable) and two DP cables in the product packaging. When connecting your devices to KVM, each computer should be connected to KVM using one KVM cable (each consisting of an HDMI cable and a USB cable) and a DP cable. Each monitor should be connected to KVM using an HDMI cable.
  1. Q: How many display modes are available for HDK202-P23?

A: The HDK202-P23 KVM offers 2 display modes. You can choose to implement 2-screen extended display or duplicate display or display different PCs on 2 monitors.
Display Mode 1: Display the same PC:dual-monitor display mode1.PNG
Display Mode 2: Display the different PCs:dual-monitor display mode2.PNG
  1. Q: How should I connect my keyboard and mouse?

A: Inside the package, you will find two KVM cables, along with two DP cables. Each KVM cable consists of an HDMI cable and a USB cable. The USB-A to USB-B cable is connected to transfer USB data between the computer and the KVM, which enables the keyboard and mouse to control computers normally. Simply connect the USB A end of the cables to their respective computers and insert the USB B end into the KVM. Then, you can connect your mouse and keyboard to the dedicated keyboard and mouse ports on the KVM.
  1. Q: Does HDK202-P23 support Bluetooth keyboard and mouse?

A: This model does not support Bluetooth keyboard and mouse, and all our KVMs do not support Bluetooth keyboard and mouse, but they all support 2.4GHz wireless keyboard and mouse and are compatible with a wide range of mechanical keyboards and mice, wireless keyboards and mice, and multimedia keyboards and mice.
  1. Q: Can I use the keyboard and mouse on two computers simultaneously?

A: Our KVMs are used to share a set of keyboard and mouse between two computers, and the keyboard and mouse are not used between the two computers at the same time, but the sharing of keyboard and mouse is achieved by switching input devices. In display mode 2 (2 monitors display the different PCs), you can double-click [Right-Alt] to switch the focus of the keyboard and mouse. This way, you can control both computers without the need to physically disconnect and reconnect the peripherals each time you want to switch between them.
  1. Q: What keyboards are compatible with your KVM?

A: Our KVM is compatible with most keyboards. Considering our KVM's dedicated keyboard and mouse ports are equipped with special hotkey chips, there are some typical reasons that may cause compatibility issues:
1. Some keyboard models use proprietary protocols that are temporarily incompatible with the dedicated ports on our KVM.
2. Certain keyboard models, when plugged into the dedicated ports on the KVM, consume excessive bandwidth, leading to compatibility issues such as keyboard lag or key sticking.
To address these compatibility issues, we recommend customers connect keyboards that encounter problems when plugged into the keyboard and mouse dedicated ports on the KVM to the USB 2.0/USB 3.0 ports on the KVM. The USB 2.0/SUB 3.0 ports do not have the built-in special chips found in the dedicated keyboard and mouse ports. Plugging your keyboard into the USB 2.0/USB 3.0 ports effectively treats it as if it were directly connected to the computer.
Due to the wide variety of keyboard models available in the market, our R&D department cannot conduct compatibility tests on every keyboard. Below are some keyboard models that have been reported as incompatible by customers: Dell KB813 (and similar keyboards with a card slot), Logitech MX series (some of which cannot manually switch between Windows and macOS modes), Roccat, and certain Microsoft keyboard models.
You can also refer to keyboard and mouse models that have been tested and approved by our R&D department:
  1. Q: Can the USB 3.0 port on the front panel charge my computer?

A: The USB 3.0 port on the front panel supports charging functionality with a maximum output power of 7.5W. So, it is designed to charge mobile phones or tablets and is not suitable for charging laptops or computers.
  1. Q: Does HDK202-P23 support audio and USB locking?

A: The HDK202-P23 does not support locking audio and USB focus. However, you can switch separately audio focus and USB focus using a set of hotkeys as follows.
To switch the USB 3.0 device connected to the KVM between 2 PCs in display mode 2, use the following hotkey combination: [Right-Ctrl]→[Right-Ctrl]→[↑]
To switch the audio focus between 2 PCs, use the following hotkey combination: [Right-Ctrl]→[Right-Ctrl]→[↓]
  1. Q: How do I switch the input sources via the buttons on the front panel?

A:
  1. Press [Select] button to switch between PCs on display mode 1.
  2. Press [A]/[B] button to switch between PCs on the corresponding monitor on display mode 2.
  3. The indicator lights blue means the current PC’s main desktop is displayed on the marked monitor, it lights green means the current PC’s subordinate desktop is displayed on the marked monitor. For example, press [A] until you see the 1 LED is lit blue, which means you have selected PC1 Input A as input for Display A; press [B] until you see the 2 LED is lit green, which means you have selected PC2 Input B as input for Display B.
  1. When switching individually, the default channel selection sequence is PC1 Input A - PC1 Input B - PC2 Input A - PC2 Input B. If one of the monitors has already determined the display channel, the channel selection of the other monitor will automatically skip the channel displayed by the previous monitor. For example, when Display A displays PC1 InputA, the PC1 InputA port displayed by DisplayA will be skipped when DisplayB is switched.
  1. Q: What are the differences between HDK202-P23 and HDK0402A1U?

A:differences between the HDK0202A2U and HDK0402A1U.jpg
  1. Q: Does the HDK202-P23 feature EDID emulation?

A: Yes, it supports EDID emulators in each input port to keep PCs always having correct display information. (Note: this function is supported only in display mode 1)
  1. Q: Does HDK202-P23 support operation at a 4K60Hz resolution?

A: Yes, the HDK202-P23 supports 4K resolutions up to 3840x2160 (4K) @60Hz, 3440x1440@100Hz, 2560x1440@120Hz, 2560x1440@144Hz(DSC), and is also backward compatible. However, this model do not support 5120x1440p.
  1. Q: How can the audio signal be transmitted from headphones to the selected computer? What cable is needed?

A: On the HDK202-P23, there is a 3.5mm TRRS headphone jack where you can connect a 3.5mm TRRS cable to transfer audio information from the headset to the chosen computer. Additionally, this dual monitor KVM switch supports the hotkey combination [Right-Ctrl]+[Right-Ctrl]+[↓] to switch audio focus between two PCs.
  1. Q: Does HDK202-P23 support G-Sync?

A: Our R&D department has conducted tests, and it is compatible with enabling G-Sync when using our KVM. According to NVIDIA's official documentation, G-Sync typically requires HDMI 2.1 or DP 1.2 and above. However, many manufacturers have implemented adaptive algorithms, making HDMI 2.0 support G-Sync(or G-Sync compatible mode) as well.
It needs to be noted that:
① First of all, your input and output source device needs to support G-Sync.
② Our KVM will not make any modification to your video signal (data pass-through)
③ Our USB 3.0 HDMI KVM Switch supports the HDMI 2.0 protocol. The maximum bandwidth is 18gbps. Using G-Sync will cause a certain instantaneous bandwidth increase.
Therefore, when you use this function, you must pay attention to bandwidth issues. Please be careful not to exceed the maximum bandwidth limit.
  1. Q: My desktop: GPU Zotac Gaming GeForce RTX 3070 Ti 8GB GDDR6X Trinity OC Triple Fan (Currently using DisplayPort cable to connect to the primary monitor and HDMI cable to connect to the secondary monitor). Laptop: HP EliteBook 830 G82). Primary Monitor: AOC 24G2U/BK. Secondary Monitor: ASUS VS228H. Keyboard: Razer BlackWidow V3. Mouse: Logitech Pro Wireless Gaming. I'm looking for a KVM that allows me to switch my two monitors, keyboard, and mouse between my desktop and laptop with a single button. If possible, I would like the KVM to provide power and video to the laptop with a single cable.

A: I believe that our HDK202-P23 KVM could be the ideal solution to meet your needs. 
Additionally, when connecting the HDK202-P23, each computer will require an HDMI cable, a DP cable, and a USB-A to USB-B cable, while each monitor will need an HDMI cable to connect to the KVM. If your device lacks sufficient ports, you may need to purchase additional conversion cables and docking stations. Our package includes all the necessary cables required for the computer end. Any additional cables or conversion cables will need to be purchased separately.
To assist you in selecting the appropriate cables for specific devices, you can check the reference list below:
HDK202-P23:
1. desktop: one HDMI cable; one DP cable; one USB-A to USB-B cable
2. laptop: one HDMI cable; one USB-C to DP conversion cable; one USB-A to USB-B cable
3. AOC 24G2U/BK: one HDMI cable
4. ASUS VS228H: one HDMI cable
Regarding whether the converter will affect the resolution, generally speaking, it should not impact the resolution. However, if there is an incompatibility issue between the converter and our device, it may cause video signal transmission issues such as flickering, black screen, or reduced resolution. We cannot guarantee it completely.
However, regarding your statement "I would like the KVM to provide power and video to the laptop with a single cable.", I regret to tell you that our KVM is unable to provide power to the devices as you mentioned.
