Does anybody know whether ThinkPad Advanced Doc has dual-link DVI output connector as the same in Advanced Mini-Doc which can drive 2560x1600 WQXGA resolution?
Regarding Advanced Mini-Doc I've seen some posts on this forum that it has dual-link DVI.
Does Advanced Doc have the same one?

RonS,
Good news! Thanks.
Did you check this yourself or only hear from somebody?

RonS,

that Advanced Dock is not dual-link DVI.
I wonder how you detected that it has dual-link DVI.
Did you test it yourself?

I tested both an Advanced Dock and Mini Dock with a 30" display running 2560x1600 resolution. I tested with both a T60p and a T61p. All combinations drove dual-link just fine.
Prior to that, in March 2007, I did a test with a widescreen T60p and an Advanced Dock where it would not drive dual-link DVI. I suspect that was a driver issue - I was using someone else's system for that test.

Does anybody know if integrated graphics can do Dual-link or just the discrete graphics?

intel GMA chipsets in the T6x support DVI-I and DVI-D up to 2048x1536 resolution.

Try Advanced Doc with dual-link graphics adapter inside.
