    I am interested in the CS1912 and I would like to know if it has active DisplayPort support monitor emulation so that when switching computers, the computer which is 'off' still thinks it is connected to the monitor.

    No.
    DisplayPort does not have provisions to allow for EDID emulation like HDMI or DVI does. It requires a constant connection.

    Hope this helps!

    What happens then when you switch the monitor from one computer to another using the switch with display port connections? Since the graphics card of the non-connected computer 'senses', there is no connection, what happens to the signal? Does the non-connected computer simply 'think' the monitor is turned off and if so, does that create any problems when you switch back to the non-connected computer?

    Every time you switch to a computer, a new video connection is established (as if you connected a monitor to the computer for the first time). The computer's graphics card and the monitor (via the KVM switch) exchange information (resolution, refresh rate, screen size, etc.) and then the video gets displayed on the screen. In practicality, this translates into a slight delay of the video showing on the screen after every switch. This is in contrast to having no delay with systems that support full video emulation (e.g. HDMI or DVI).

    Hope this helps!
