Product: HP Z840
Operating System: Microsoft Windows 10 (32-bit)
What KVM extenders are supported with a Z840 and Z640, I have tried 2 different Gefen extenders (DVI and VGA) and some HDMI extenders and all of them have issues causing each workstation to not POST. The only way around it is to disconnect the extenders and reconnect them after the workstations have fully booted.
