I have no idea if nVidia is going to release a DVI-D equipped M2000D variant but from what I gather the industry is pushing for the abandonment of obsolete technology such as DVI-D in favour of the adoption of successive versions of Display Port which can handle the ever increasing resolutions of modern monitor designs which industry is gravitating to.
I’d expect that what you’ll have to look for is either an older Quadro card or a DVI-D DL (2560x1600) active adapter–which actually works…
[i]"…A notable limitation of dual-mode is that it can only transmit single-link DVI (and HDMI), as the number of pins in the DisplayPort connector is insufficient for dual-link connections. As a result, an active converter is needed for Dual-Link DVI and analog component video such as VGA. Some of these active adapters can rely on the +3.3 V wire in the DisplayPort connector for the conversion, but other types of active conversion, such as Dual-Link DVI, require external power that is often pulled from an available USB port.
VESA anticipates that HDMI and DVI conversion will eventually be handled by active adapters which act as DisplayPort Sink devices, in order to facilitate easier updates to latest HDMI and DisplayPort specs, and work with dual-link HDMI, DisplayPort connections with either fewer than 4 lanes or different data rates, and multiple DisplayPort streams. It should be noted that DVI 1.0 spec was finalized in 1999 and the DVI industry consortium has since disbanded, so future updates to DVI specification are unlikely; also, although dual-link HDMI Type B connector is defined in the HDMI specification, it has not seen any practical use as of 2012…"[/i]
