Thanks for posting! Appreciate you providing those details about your requirements and setup.
Based on this information, I would recommend you to consider our USB 3.0 Dual Display Universal docking station (UD-3900). Assuming you have an available USB 3.0 port on your Lenovo system, it can drive up to two 1080p displays via one HDMI port and one DVI port (or VGA through an included DVI-to-VGA adapter). Additionally, the dock provides gigabit Ethernet connectivity and a total of six USB ports (2x USB 3.0 ports, 4x USB 2.0 ports).
