1. What can I do if there is no video output?
Check if you have connected the host PC to the right zone of switcher and it is selected.
Check if you have chosen the right HDMI input channel on your display device.
Make sure all of your HDMI cables work normally. You can connect the source to the display device directly via one of
these HDMI cables, to check if video can be shown normally on the display.
2. HDMI video can work, but USB connection is not working. What can I do?
Please ensure you connect the PC to the "HDMI In" Port and "USB Host" Port in the same group.
Please ensure you connect your USB devices to the right two USB 2.0 ports on the front panel of the KVM switch.
Try connecting the USB host cable to another USB port on your PC.
Try connecting the USB devices to the PC directly without using the KVM switch. Then check if the USB connection works.
3. What can I do if the hotkey is not working?
Please ensure your keyboard is connected to the left white USB 1.1 port (with a keyboard icon below).
Quickly press one of the four hotkeys twice (Tab/Caps Lock/Left Ctrl/Right Ctrl) on your keyboard to activate it or switch
to it. The default hotkey is "Tab". For example, if you want to use "Left Ctrl" as a hotkey, press the "Left Ctrl" key twice
quickly to switch the hotkey to it, then other hotkeys will be invalid.
Ensure you operate the hotkey in a correct way. For example, if the present default hotkey is "Tab", you can press "Tab"+
"1"/"Tab"+"2"/"Tab"+"3"/"Tab"+"4" to switch to HDMI input 1/2/3/4 respectively. You can also press "Tab" + "→"/ "Tab"+
"←" to switch to the next or the previous input source.
4. What can I do if the USB connection is intermi ent and not stable?
Check your USB cable connection, or try using shorter USB cables with be er quality.
Try connecting the USB devices to the PC directly without using the KVM switch. Then check if the USB connection works.
Power on the KVM switch once again to check if it can help.
5. What can I do if there is no audio output from the 3.5mm audio port?
Check your headset's 3.5mm audio jack. It should have 3 pins instead of 4 pins to match the KVM switch's audio port.
Check if you have selected the headset as an audio output device on your PC.
6. What can I do if the IR remote controller is not working?
Check if the ba ery has run out of power.
Check if the ba ery is installed correctly and on the right position.
When you use the remote controller, it needs to be directly facing the receiver head of the IR extension cable, or facing
the IR receiving window on the front panel of the KVM switch.
