Only One Display is Working

Only One display is working | Display not working | One monitor working only

Edit By Fiona & Zeki, Customer Service Center 

 

1. 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 KVMs output to the monitors. Both displays should work when Mode 2 is active. This confirms the KVM output is working fine. 

 

2. If you have only one monitor working, it is likely either 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. 

 

3. Some Suggestions for Troubleshooting:

All input devices need to plug 2 video cables into KVM. (HKS0402A1U, HDK0402A1U, HCK0402A1U, PKS0802A1U, HKS0802A1U); All "Display 1" and "Display 2" means the screen printing of KVM.

  • STEP1---Keep the cables and KVM connection ports unchanged, and then exchange the monitor connect to Display 1 with that to Display 2, and check the working status of them after the exchange.

1) The monitor that work properly before ——> still works properly

    The monitor that cannot work before ——> still cannot work.

    That means this monitor is malfunctioning.

2) The monitor that works properly before ——> cannot work anymore.

    Go to STEP 2.

  • STEP2---Maintain the connection state completed in STEP 1 and do not change the position of the monitors and the ports. Exchange the connection cables(which connect the monitors and KVM), and observe the working status of the monitors now.
