ThinkPad Advanced Mini Dock (250410U)+two LCD

such as Subject, i have a Mini Dock connect with two LCD, one with DVI and other with D-Sub. But the problem is,all of three monitors(including Laptop Monitor)can not display at the same time,only two of them work.

is it a problem of graphiccard(X1300) or only 2 are allowed to display?

Hi meng,


Welcome to the Lenovo forum.


You are correct, the X3100 GPU can display (only) two screens at a time. If you need more screens, you could use a USB-DVI converter like this one. Another member reports good results with it in this thread.
