HKS0402A1U / 2 in 2 out / 2 Port Dual Monitor KVM Switch
Q1. Is this suitable for a KVM switch that supports 2 laptops and 2
monitors?
A1. Yes, this KVM switch is suitable for 2 laptops and 2 monitors. It offers the
following functionalities:
Mirror Mode: Both monitors can simultaneously display the mirrored content of the
connected laptops.
Extended Mode: Both monitors are capable of displaying information from the same
computer in extended mode.
Dual Display Mode: Different laptops can be displayed separately on the two
monitors.
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+...".
Q6. Does the dual-screen HKS0402A1U support resolutions of
5120x1440 and 3440x1440?
A6. You can refer to the detailed information in the image provided below. Currently,
our KVM does not support a resolution of 5120x1440, but it does support a resolution
of 3440x1440 at 60Hz.

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 wireless keyboard and mouse?
A10. Our KVM supports 2.4GHz wireless transmission technology, and supports 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 one-
way, 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.).
Direct connection test reference picture:
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:
- 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 pass-
through 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.
2. After-sales FAQ
Q1. How to turn off the buzzer?
A1.
- The buzzer can be turned on or off by the hotkey combination Scroll Lock +Scroll
Lock + F11.
- If the hotkey trigger key has been switched to the right ctrl, you can simultaneously
Right-Ctrl + Right-Ctrl + F11 to turn on or off the buzzer.
Q2. Does the product have a factory reset function?
A2. The product does not have the function of restoring factory settings, what
problems do you encounter? You can contact us in the lower right corner.
Q3. Does the keyboard have no right alt key to switch the mouse and
keyboard?
A3. If there is no right alt button on the keyboard, you can't use the hotkey to switch
keyboard and mouse, but HKS0402A1U can swap keyboard and mouse position by
remote control.
Q4. Does the product support firmware updates?
A4. There is currently no firmware update for the product, what problems do you
encounter? please feel free to contact us through the bottom right corner.
Q5. When using an assembled computer, when connecting to a KVM
product for image output, should I choose an independent graphics card
or an integrated graphics card?
A5. The correct choice is to use the ports on the discrete graphics card to connect to
the KVM product. If both discrete and integrated graphics are present in the PC, the
integrated graphics may be disabled, so it is important to use the ports on the
discrete graphics card for best performance.
Q6. Can the HKS0402A1U dual-screen KVM switch use monitors
alternately between PCs? For example, can PC 1 use monitor 2 and PC 2
use monitor 1?
A6. The 2x2 KVM switch can alternate monitors with the "P" key on the remote.
Additionally, you can switch monitors between PCs using the hotkey combination
Scroll Lock + Scroll Lock + 3/4.
Q7. Does the product support 7*24 hours of work?
A7. Our products support the power being turned on all the time, but in order to
prolong the service life of the KVM, it is recommended to turn off the power when not
in use. If the KVM needs to keep working without power for a long time, it is
recommended to check the working status of the KVM regularly and confirm whether
the power supply environment is stable.
