Pre-requirements for any of the dual monitor KVM's to work correctly with both the monitors:
1. Two video connections going out of each machine in to the KVM
2. One USB connection from each machine in to the KVM
Our dual monitor KVM's come in different combinations of ports such as HDMI+VGA. HDMI+HDMI or HDMI+DP.
Using either with any of your personal machines please make sure that you have two video outputs available.
Laptops usually use a docking station that comes with more than one video outputs. Please remember that you may need appropriate connector/adapters in order to be able to go into the KVM if the link is not a direct connection such as an HDMI out on the computer and HDMI in on the KVM. There may be cases where one might have to consider adapters when the available port on the laptop is not HDMI.
When there is no matching ports available you will have to bring in the converters.
Please refer to the diagrams below for your specific model to have better visual understanding of the setup:
1. Models: HKV0402A10, HKV0402A1U
2. Model: HKS0402A1U
3. Model: HDK0402A1U
If you have all the connections correct and still have issues achieving the correct setup, here are some steps to go through:
- Check for bad cable (Swap with any other available cable)
- Non-standard resolution than the other working monitor (Try to change resolution for the problematic monitor to the same as the other working monitor)
- Verify Bad ports; either on the KVM or computer side (On the computer side, swap it with another machine if available; or, plug in the same computer on the other open slot on the KVM)
- Docking station issues(This one is not easy to troubleshoot because people would usually have only one docking station available at hand but its the least likely of all the problems listed above)
- KVM Power cycle the KVM. It will reset all the communication with the devices and start all over again. Useful if there is communication/signal problems
- DOA(Faulty power adapter/ faulty KVM board)
