HKV202-E23 (Previously HKV0402A1U) FAQ

Pre-sales FAQ:

  1. Q: How do I connect my devices to the HKV202-E23?

A: There are two KVM cables (each consisting of an HDMI cable and a USB cable) and two VGA 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 an additional VGA cable. Each monitor should be connected to KVM using an HDMI cable.HKV0402A1U connection.PNG
  1. Q: How many display modes are available for HKV202-E23?

A: The HKV202-E23 KVM offers 1 display mode. You can choose to implement 2-screen extended display or duplicate display on 2 monitors. It doesn't support displaying content from two different computers on two separate monitors simultaneously. dual-monitor display mode1.PNG
  1. Q: How should I connect my keyboard and mouse?

A: Inside the package, you will find two KVM cables, along with two VGA 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 keyboard and mouse to the dedicated keyboard and mouse ports on the KVM.
  1. Q: Does HKV202-E23 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: 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/USB 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.

  1. Q: Does the HKV202-E23 feature EDID emulation?

A: Yes, it supports EDID emulators in each input port to keep PCs always having correct display information, and prevent display setting changes while switching input ports.
  1. Q: Does HKV202-E23 support operation at a 4K60Hz resolution?

A: Yes, for HDMI, it supports 4K@60Hz. But for VGA, it supports 1080P@60Hz. However, this model do not support 5120x1440p.
  1. Q: Does HKV202-E23 support pass-through mode?

A: Yes, it does. Pass-through mode is a built-in function of KVM, which is able to improve keyboard and mouse compatibility and enhance user experience. In the pass-through mode, the keyboard and mouse are equivalent to directly connecting to the computer. At this time, you can use more keyboard and mouse functions and special functions that are not supported by traditional KVM.
  1. Q: I need a KVM switch that Allows 2 HDMI monitors, 1 USB keyboard, 1 USB mouse, 1 USB webcam, 1 USB speakerphone To connect to 1 desktop (HDMI and VGA ports or USB) and 1 laptop which has 2 type c ports and 2 USB ports and HDMI port. Which model can you recommend? The monitors are Samsung 27-inch Super Slim Curved Monitor LC27F390FHEXXS | VA Panel | 60Hz Refresh Rate.

A: Based on your situation, we have HKV202-E23 KVM which could meet your demands.
It is important to note that each computer will require 1 HDMI port, 1 VGA port, and 1 USB-A port and each monitor will require 1 HDMI port when connecting HKV202-E23. 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:
HKV202-E23:
1. desktop: one HDMI cable; one VGA cable; one USB-A to USB-B cable
2. laptop: one HDMI cable; one USB-C to VGA conversion cable; one USB-A to USB-B cable
3. Samsung monitors: one HDMI cable EACH
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.

  1. Q: Is it safe to use your KVM?

A: Yes, it is. Our KVM falls under the category of physical KVMs. It is designed specifically for switching and transmission of audio, video, and USB data. One remarkable aspect of our KVM system is that it functions independently of internet connectivity; it simply requires a power connection to operate.
Our KVM employs a direct data transmission mode, ensuring that no alterations are made to the transferred data during the process. Furthermore, it is important to note that the KVM does not possess any storage functionality, alleviating any concerns about potential data leaks. Essentially, our KVM serves as a dedicated device that not only ensures an absence of data exchange between connected hosts but also facilitates the shared use of a single set of keyboard, mouse, and display between two host systems, all achieved through a physically isolated switching mechanism.

A: 1. We specialize in a variety of KVMs, including single-monitor KVMs, dual-monitor KVMs, and triple-monitor KVMs.
2. Our multi-monitor KVMs offer two display modes: dual-screen mode (where both monitors simultaneously display the same input source) and extended screen mode (where both monitors simultaneously display two different input sources).
