FAQ & Trouble Shooting

  1. Make sure the USB 3.0 cable is already connected from each computer to correspondent USB B port on the switch.
  2. Some keyboard and mouse with special features may not work well with the hotkeys on USB keyboard and mouse port, if so, please use the USB 3.0 HUB port(s), or turn off the hotkeys, without hotkeys, user can use the the wired remote or IR remote or front button to switch between computers and display modes.
  3. For wireless keyboard and mouse which share a unified dongle , the dongle must be plugged into the port marked with keyboard (with hotkeys), or USB3.0 HUB (no Hotkey).
  4. Power cycle the KVM switch and reboot computers to re-identify the USB devices, if the keyboard and mouse stop working after a certain time of use.
  5. If keyboard and mouse stops working on one computers, press the right Ctrl twice, then Esc 3 times, then Enter to restore the KVM switch to factory settings, make sure hotkey is on and the keyboard is plugged in the USB keyboard port when doing so, or swap the USB cable to see if the cable issue.

  1. Make sure to power off everything before installation.
  2. Check if the cables and power adapters are well connected ; or swap the cables to see if it is cable or adapter problem.
  3. To get dual monitor display, make sure each computer has 2 video connections to correspondent IN A and IN B ports.
  4. Power cycle the KVM switch and reboot computers to recognize monitors.
  5. Avoid using adapters on both computer and monitors for a same video flow. For example, if an adapter is used for connecting IN A port, then do not use another adapter for connecting monitor A.
  6. Pay attention to signal converting direction, eg. If you want to convert USB C on computer to HDMI input on the KVM switch, correct direction should be USB C to HDMI, If you are converting HDMI Out put on the kvm switch to a VGA on monitor, correct direction should be HDMI to VGA.
  7. VGA to HDMI, HDMI to VGA or HDMI to DP needs to be at least USB powered. DP adapters need to be active type.
  8. We prefer to use adapter with chips instead of simple conversion cable without chips. Some adapters/conversion cables/docking stations may work directly with computers but may not work through the KVM switch. Please reach out to seller for recommendation.
  9. Try to power cycle the KVM switch, or unplug and replug cables, or reboot computers when there is display issue.
