Hi there.
I have two HDMI monitors, both plugged into the KVM where one uses a DisplayPort male to HDMI female adapter. When plugged into my mac both screen works but they mirror each other instead of being independent. The mac laptop screen works independent from the two displays.
The monitor plugged into the HDMI port of the KVM is the monitor that shows in the display settings of my MAC. Which leads me to believe that the issue is with the adapter. The adapter is an old adapter so my hope is that I just need to replace it with a more modern adapter. I also don’t have a DisplayPort monitor so I can’t test my theory. Unfortunately I am still waiting for my motherboard upgrade on the second computer with a type-C adapter. I do have a type-C port on the second computer’s GPU but just plugging the KVM in does nothing. So I don’t know if it is only Mac related.
My question is whether the adapter is the issue and if it is the issue would a new modern or a specific adapter solve my problem or will I have to return the product?
