Thinkpad X220 with Dual External Monitor through ThinkPad Mini Dock Series 3

Dear all,


would like to inquire if X220 will operate with two external monitor? I'm ok to close the lid of my X220.

The 4337 docks support VGA and DVI, will both work together?


What's working:

- I have been using x220 screen with another external monitor through VGA connection.

- Connecting Dell 2340L direct to VGA works with X220 screen, not with 2 external monitor.


What's not working:

- Recently got a Dell 2340L which contains only VGA and HDMI, which I thought HDMI would work with an adaptor (HDMI to DVI) port - no response although the Windows 7 detects external monitor display.
