8KSW21DP Issue with video signal

I recently purchased an 8KSW21DP from amazon, and I have 2 monitors connected. However, my Samsung LU32J590UQNXZA is not receiving signal output while both monitors are connected. It is set to DP1.2, and I have confirmed that the ports, cables, and monitor all work.
I tried updating to the 1.0.2 firmware, and it is up to date.

Hello Scott,

Thanks for contacting us and we are truly sorry for the issue.

  1. Both two inputs requires connected from PC to KVM.
  2. Are there have any adapter or not? Sch as PC not have 2 DisplayPorts no use the HMDI to Displayport adapter/cable? If so you need to use the HDMI to Displayport type, but not DisplayPort to HDMI( mostly this type adapter/cable come with this one-way transmission).
  3. Does the PC detected the monitor or not? if yes and please try lowering the resolution and refresh rate to have a check.
