problems of dual monitors on X230

[verbatim]

I have X230 on dock station which has one VGA and one displayport; and I have one monitor acer v223w( 1680 X 1050 recommended) and another monitor HP Compaq LA2405x (1920 X 1200 recommended), I connected X230 on dock through displayport to DVI to LA2405X and through VGA to v223w when closing lid of x230.

Resolution and display on LA2405x is fine. however, if I use 1680X1050 for the second monitor v223w, the display is not full, there is a black band I believe belong to LA2405x on the right side close to LA2405x. For example, when I move mouse pointer on the v223w, it can disappear within that black band and directly go to the LA2405x; I am feeling the whole display of v223w move to left for the distance of that black band. Any ideas of this? Thanks for help in advance

Did you try 'autoadjust' on the one you connected by VGA?
