I have an XPS 13 and an DA300 adapter which I use for connecting my U2311HM monitor via its DisplayPort.

I am looking into purchasing an additional monitor (probably another Dell but not sure at the moment) - as far as I know I can only use one video port from the DA300 at a time (DP, HDMI and VGA).

What would be my option for connecting an additional display? Shall I have both displays working if I go for something like this?
