Do any Thunderbolt 2 docks allow for 2 displays (Non Apple TB Display) off one dock?

    Looking to buy a TB2 dock for my 2013 rMBP 15" and want to use 2 monitors. It looks like most, if not all, of the current docks only support one display off of the dock as a design decision, to allow second dock or Apple TB Display compatibility. See the last section here:

    Are there any docks that demultiplex both display signals immediately and thus allow for 2 displays?

    No, one display must be thunderbolt in all cases. You could use two docks and daisychain them, however.

    basically every thunderbolt chip has one display port. the thunderbot display has 1 thunderbolt chip so it uses the diplayport for itself and cannot connect another display, like wise a dock will use the displayport for hdmi out leaving the thunderbolt port without displayport. The next thunderbolt may have another.

    use a usb3 dock. Basically it will use displaylink (software rendering).

    Just a minor detail, but the dock will only consume the display port when an HDMI monitor is attached, otherwise it passes DP through to the next device in the chain... which could be a DP monitor.

    Interesting, but I was hoping to use a 4k monitor off the dock so I don't think USB3 would be able to handle that at a decent refresh rate.

    Exactly, I guess I'll have to go with a dock + 4k monitor and the second monitor will go to the other TB port. Someday my single cable dream will come true :cool:

    Sorry i guess you can add a thunderbolt hardrive to the chain and connect a monitor to the drive
