Questions about Lenovo ThinkPad OneLink Pro Dock

The ThinkPad OneLink Pro Dock is generally compatible with earlier models of the ThinkPad X1 Carbon, such as the 3rd generation (20BS) and specific other models like 20BT, 20A7, and 20A8. However, compatibility with the 11th generation (Gen 11) of the ThinkPad X1 Carbon is not explicitly listed in the available information.

I don't know the difference between old and new, I've had the unit since October 2014. Can't give any other answer unfortunately. Robert0401

To question 1: I don't know, I have E560. To question 2: It has 1 DVI and 1 HDMI output. Greetings

And what about compatibility with the Lenovo Y50-70? It's not listed either. What do you recommend for a docking station if this one doesn't work?
