to be recognised
KVM Mode
Troubleshooting / FAQ
My hotkey commands don’t work or stopped working
- Make sure the keyboard is plugged into dedicated mouse/keyboard ports
- Try using Scroll Lock as a hotkey trigger, if not, then Right-Ctrl. My keyboard does not have a Scroll Lock button
- There are two kinds of trigger hot keys in this product, the default is the Scroll Lock key, and the alternative is the Right key.
- If the Scroll Lock Key has been used for other functions, you can switch the hotkey to Right-ctrl by:
- Method 1: 10 seconds after powering on the KVM, press and keep holding the set button on the front panel until you hear the buzzer beeping, then restart the KVM.
- Method 2: Press Scroll Lock→Scroll Lock→F1, and you will switch the control hotkey to Right-ctrl. Vice versa, Press Right-Ctrl→Right-Ctrl→F1, and you will switch the control hot keytoScroll Lock.
Keyboard/Mouse Issues
Jumpy mouse erratic behaviour repeating keys | multimedia keys not working | No mouse | No keyboard upgraded this KVM keyboard and mouse compatibility The new generation pass-through mode is built and opened by default, which further expands the compatibility of the keyboard and mouse and enhances user experience. At this time, you can use more keyboard and mouse functions and special functions that are not supported by traditional KVM.
Simplifies user operation
- There is no need to turn to pass-through mode on/off, so there will be no compatibility issues caused by accidentally turning the pass-through mode off.
- No longer need to use the hotkey to determine whether the mode is turned on. 2.1 My Mouse & Keyboard Are Not Working.
- First of all, make sure you have the USB connection established
If you’re having erratic mouse behaviour, dropouts, or repeating keys when connected to the dedicated mouse/keyboard ports, this could be because the dedicated mouse and keyboard ports have EDID programming. This emulation is what allows the switch to receive hotkeys and mouse gestures but conflicts with gaming peripherals and select mouse/keyboard brands
Solution 1
We see issues occur sometimes when there is Logitech keyboard/mouse
software (corsair, razer etc.) installed into the computer. You can search
your “Apps & Features” and uninstall this software. This should stop the
conflict between the hotkey software and keyboard/mouse software.
Solution 2
Another possible cause could be IR interference if you’re using a wireless
keyboard/mouse since the USB port is in the back of the KVM. There could be
interference due to distance and the cables. Using a USB extender to bring the
USB dongle closer to the devices will strengthen the connection. If that still
doesn’t work we recommend using the USB 2.0 port with a powered USB hub as a
workaround. Because the USB port does not have EDID emulation, keyboard
hotkeys and mouse gesture switching are not available to devices that use the
USB input.
Video Signal Issues
Blank Screen | No video | Monitor not working | Flashing/Blinking | Only one
computer displays | Port #not working |
Only One Display Is Working
One monitor working only If you have at least 1 video connection from each computer then using the Mode 2 feature (each computer on each monitor) you can test the KVM output to the monitors. Both displays should work when Mode 2 is active. This confirms the output is working fine. 3.1.2 If you have only one monitor working, you’re likely missing the second video connection or the dock/adapter you’re using is incompatible. Even if the adapter works when not connecting it to the KVM, it is possible that the adapter does not work well in the KVM environment.
STEP1
Keep the cables and KVM connection ports unchanged, and then exchange the
monitor connected to Display 1 with that to Display 2, and check the working
status of them after the exchange. The monitor that worked properly before ——>
still works properly The monitor that cannot work before ——> still cannot
work. That means this monitor is malfunctioning. 2) The monitor that worked
properly before ——> cannot work anymore.
STEP2
Maintain the connection state completed in STEP 1 and do not change the
position of the monitors and the ports. Exchange the connection (which
connects the monitors and KVM), and observe the working status of the monitors
now.
-
The monitor that cannot work before ——> works properly
-
The monitor that works properly before ——> cannot work anymore
-
That means the cable of this monitor is malfunctioning. 2) The monitor that worked properly before ——> still works properly
The monitor that cannot work before ——> still cannot work -
That means the KVM is malfunctioning. Any other questions, please feel free to contact us. 3.2 Flashing Monitors/No Display
Flashing Monitor | Snow screen | Blank Monitor
- The following are some common reasons that cause this situation Cable- It’s pretty rare but sometimes the video connection could fail. Try testing this connect
- Bad Port- Either on the KVM or computer side. On the computer side, swap it with another computer if available. On the KVM test the failing port with another computer that is known to be working with the KVM. If the issue (keyboard/mouse) fails, make sure you have the Online Light on, it indicates that the USB connection is active.
- Generic Adapter/Converters- If you are using adapters/converters in the connection stream this is often a point of failure. Non-standard Resolution than the Other Working Monitor- Try to change the resolution for the problematic monitor to the same as the other working monitor. It’s possible that the selected resolution is not supported by the therefore this will result in a blank screen or flickering.
- Docking Station Issues-Its pretty rare to have incompatible docks but it does happen with some older docking stations for example the HP UltraslimDock2013
- Monitor-Make sure the monitor is set to the right input source.
Dual Monitor Display Troubleshooting
Only One display is working | Display not working | One monitor working only If you have at least 1 video connection from each computer then using the feature (each computer on each monitor) you can test the KVMs output to the monitors. Both displays should work when Mode 2 is active. This confirms the KVMoutput is working fine. If you have only one monitor working, it’s likely that you’re missing the second video connection or the dock/adapter you’re using is incompatible. Even if the adapter works when not connecting it to the KVM, it is possible that the adapter does not work well in the KVM environment. If PC 1 works well with both monitors but PC 2 does not then you can swap PC1 over PC 2 Inputs. If PC 1 works fine on both inputs this confirms the KVM is working fine and the issue is related to PC 2. Could be the port, adapter or dock being used.
Audio Issues
My audio isn’t working | speakers are not working | no audio
How Do I Get the Audio to Work?
Your computer will transmit audio via the video connections, such as HDMI
cables. Please confirm what output interface is the computer equipped with.
(DVI? HDMI?) If your computer is equipped with DVI output, normally the DVI
output does not carry audio signals, so the audio signal cannot be output to
the speaker. If you have an external device plugged into the audio mini-jack,
the switch duplicates the audio signal from the HDMI input to the monitor and
mini-jack out.
After you connect the headset, you need to switch to the computer with the audio device turned on. Only the computer that controls the audio playback will output audio. Generally, we just try all of the outputs one of them is correct. If the audio is not working, please go to your sound settings and choose the correct output device. This is typically listed as the monitor that is connected to the KVM because the audio is transmitted via the video connections. (Right-click the speaker, open the sound settings, select the correct HDMI output device, and set it
Refresh Rates/ Resolution Issues
We see refresh rate/resolution issues all the time when using adapters to
connect to the KVM. It is important to remember the connection flows FROM the
computer to the KVM. For example, if you need to convert a USB-C connection,
it would be a USB to an HDMI Adapter. we are aware that not all adapters work
well in a KVM environment. A common issue we hear about is monitors not
displaying the correct high refresh rate. This can be checked on the manual of
your monitor it will demonstrate what refresh rates are supported via HDMI.
