Review on Enhance Connectivity with the Lenovo ThinkPad Basic Dock 90W - Black (40A00090US) by Art Porras

I got this for my Lenovo T570. It works great. I have a monitor arm and use my laptop screen as my main monitor and the monitor above it as my second monitor. Not the preferred setting. I would say this document will be helpful if you need 2 monitors. Many of today's monitors still have a VGA connection. However, if you prefer monitors with display ports, spend a little more for a dual display port dock. I use this at work. It gets a maximum of 3 monitors including laptop screen.
