Switch DisplayPort KVM switch

I’m looking for the following specs on a desktop KVM switch:
1) 4-ports
2) Single monitor port DisplayPort v1.2, but supports daisy-chaining from one monitor to the next (not connecting two monitors directly to the computer or KVM)
3) Port emulation (to maintain connection with computers that are not currently selected so that when you switch to it, the computer doesn’t have to recognize the video & USB again)

Can you recommend one?

 

DisplayPort v1.2 supports Multi-Stream Transport (MST), which provides the ability to connect the video as follows:

Computer —> KVM —> Monitor1 —> Monitor2

The Dell U2415 monitor supports this:

I’m looking for a KVM that can pass on the MST signal.

The AdderView 4 PRO DisplayPort only supports DisplayPort v1.1, so that won't work.

It appears that the DPN-4P has DisplayPort v1.2, but just can you confirm that it supports 1) daisy-chaining of monitors and 2) provide video emulation so that it maintains the connection with computers that are not selected so that when it is selected the computer doesn’t have to re-recognize the monitor?

Thanks.

 

Thank you for the info. Do you have any other KVM switches that support those requirements?

 

Thank you very much for looking into this. I greatly appreciate it! I look forward to the results.

Thanks.
