The ThinkPad Multiple Monitor Configurations pdf (LINK) says the DVI port on thinkpad Mini Dock Series 3 only support up to 1920x1200, but I would like to connect the DVI-D port to a external monitor with 2560x1600 resolution. Will it work? I am planning to buy a T420 with a discrete Nvidia Optimus video card and a mini dock series 3. Yes, I can't use the display port because the external monitor only have DVI-D port. I knew that the DVI-D port is able to support 2560x1600 resolution as long as the video card support it, I don't understand why the DVI-D port on the thinkpad mini dock series 3 can only support up to 1920x1200 even though the Nvidia Optimus Technology is powful enough. Please share your experience and suggestions. thanks.

yes, you are right. it says it's DVI-D single link on lenovo, but the image of mini dock series 3 clearly shows the DVI-D port is dual link. here are some images. I am quite confused.

I am not sure about the answer at all. I am just so confused. That's why I was posting this question here. I thought the lenovo tech will come here and give answers to my qustion. lenovo, please help!!! Why does your company label a DVI-D dual link port as DVI-D single link? It just doesn't make any sense.

Oh, I see.
OK, for the people with similar question， there is the final conclusion based on lead_org's response：
For the DVI-D port on lenovo mini dock series 3:
It only has the DVI-D single link function, but it has the same appearance as DVI-D dual link port, as you can tell the images I have uploaded. Some on-site image of mini dock I have searched shows the same DVI-D dual link appearance.
The DVI-D single link port on mini dock series 3 only support up to 1920 resolution, even though the appearance of the port is same as DVI-D dual link. Only DVI-D dual link port can support up to 2560 resolution.
Buyer beware please!
