Q on monitors and resolutions thru Advanced Mini Dock

[tlc]

Which variations of the T60/60p/61 support at least 1900x1200 externally when used with the Advanced Mini Dock (and no extra video card)?

Do any support external Dual heads at 1200x1024 each via the AdMiniDock (with no extra video card)? (I'm not interested in one external and the laptop LCD.) Do I need the Advanced (non-mini) Dock and a vid card for this?

Thanks!
