Display Mode Description

Q2. Does using a KVM switch lead to a degradation in display quality for the monitor?

• A2. Our KVM supports a maximum resolution of 3840 2160@ 60Hz and is also downward compatible. As long as your input devices and display can support 3840 2160@60Hz, your display quality will not be compromised. If you notice a decrease in image quality on your monitor, please check your display settings to ensure that it is set to 4K 60Hz

Q3. Does the dual-monitor KVM require an additional docking station to operate?

• A3. It is recommended that you purchase a KVM with the same port as the computer to ensure video quality. If you only have one HDMI port but have other video output ports (such as Type-C, VGA, DP, or DVI ports that support video output), you can use a reliable converter to achieve dual-screen expansion.

Q4. Will the USB A/B cable control the keyboard and mouse at the same time?

• A4. Yes, the USB A/B cable will allow simultaneous keyboard and mouse control.
  The USB A/B cable connects the KVM switch to your computer, enabling the transmission of data between the KVM switch and your computer. This allows you to control the keyboard and mouse between different computers.

Q5. If my keyboard doesn’t have a scroll key, how can I switch between dual-screen displays?

• A5. Press the panel button “SW” button until the buzzer beeps for a long time, restart the KVM, and you can switch the hotkey to “Right Ctrl+Right Ctrl+…”.

Q7. Does HKS0402A1U support EDID emulators?

• A7. This HDMI + HDMI dual display KVM switch (HKS0402A1U) supports 2 display modes (mode 1: Mirror Mode and Extended Mode, mode 2: Dual Display Mode). Display Mode 1 supports the EDID emulators function, which can ensure that the previous screen windows will not be rearranged when the input source device is switched. However, Display Mode 2 does not support EDID emulators

Q8. Before purchasing the HKS0402A1U, I have a compatibility question. My laptop has one USB-C and one HDMI port. Can I use the HDMI port and another USB-C to HDMI adapter for video output?

• A8. Before purchasing the HKS0402A1U, please note that compatibility depends on the specific capabilities of your laptop’s USB-C port. In general, if your USB-C port supports video signal transmission, you can try using a USB-C to HDMI adapter to directly connect a display to your laptop (without going through the KVM switch) and check if the display shows correctly. If it displays appropriately when connected directly, it should work fine when connected to the HDMI+HDMI KVM switch.

Q9. What is the keyboard hotkey for switching between two laptops?

• A9. Double-click Right-Alt to switch all input (i.e. keyboard, mouse, speakers, etc.) from PC 1 to PC 2, and double-click again to switch it back to CP1.

Q10. Does HKS0402A1U support a wireless keyboard and mouse?

• A10. Our KVM supports 2.4GHz wireless transmission technology and allows you to connect the USB receiver of the wireless keyboard and mouse to the KVM for use. For some brands, you must open the control software to use the USB receiver, which may cause compatibility problems when using it on the keyboard and mouse. At this time, you can only connect the wireless receiver to usb2.0 for use (so you will not be able to use the Hotkey function); It should be noted that our KVM does not support wireless Bluetooth technology.

Q11. Can you recommend DP to HDMI expansion docking station?

• A11. There are many different brands on the market and it is not possible to test all models, so we cannot recommend an exact model for you. Most adapters are oneway, for example, you need to confirm that the adapter is DP to HDMI, not HDMI to DP. The following is the conversion principle of the docking station and the converter

Q12. How to create a dual-screen display when the computer has only one video port?

• A12.
  •  There is only one USB-C interface: to distinguish between Thunderbolt 3 and 4 or ordinary USB-C interface (it is best to provide the product model to customer service), one interface of Thunderbolt 3 and 4 can transmit 2 audio and video signals at the same time, ordinary needs direct testing.
  • There is only one DP interface: a direct connection is required to test whether it supports the transmission of two audio and video signals at the same time
  • Only one VGA port: Is there a USB-C or USB-A port to allow the use of a conversion cable (if there is only one video output port, it is basically not recommended to use the dual-screen function, if you must use dual-screen anyway,
  • it is recommended to use USB-A to HDMI converter, but the picture quality and usage effect may be affected by the converter.).

Q13. Can all Thunderbolt 3/4 ports support two external monitors?

• A13. Most of the Thunderbolt 3/4 ports can support two external displays, but the MacBook is special, we need to carefully check the description of the display support on the official website to confirm. At the same time, you can use the direct connection test to determine whether two external displays can be supported at the same time. The screen output of the query through the Mac official website:
  • The computer supports only one external monitor:
  • The computer supports multiple external monitors:

Q14. What kind of cable is equipped with HKS0402A1U?

• A14. Most display devices come with cables, so we only included cables for inputs.
  The input terminal contains 2 (HDMI+USB) cables and 2 HDMI cables.

Q15. Why does every computer need two HDMI port inputs?

• A15. Due to the absence of MST-multi-streaming in HDMI, each HDMI output can only handle a single video signal independently. In dual-screen mode, two distinct video signals need to be output simultaneously. Therefore, a PC must have two HDMI ports active simultaneously to achieve dual-screen output.

Q16. Can I copy content on PC1 and paste it on PC2?

• A16. No, you cannot directly copy content on PC1 and paste it on PC2 using this KVM switch. Its primary purpose is to switch control between different computers, but it doesn’t provide a mechanism for copying and pasting content between them.

Q17. What is the pass-through mode?

• A17. The pass-through mode is a built-in function of the KVM, which can improve the compatibility of the keyboard and mouse and enhance the user experience. In passthrough mode, the keyboard and mouse act as if they are connected directly to the computer. At this time, you can use more keyboard and mouse functions and special functions that are not supported by traditional KVM
