Dual link DVI uses two 24 bit data paths running in parallel to double the bandwidth. This allows supporting higher resolution 24 bit displays only.
This is what is listed on page 5 of the NVIDA 30 bit Technology PDF at the link I provided:
DisplayPort DisplayPort allows a mode with 10 bits per component or 30-bit color. This is the approach explained in this paper.
Dual-link DVI DVI will not natively support 30-bit deep color. It is possible to enable 30-bit color over DVI using device specific pixel packing method. In this approach, off screen buffers are used for rendering at a deep color value and a fragment shader is used to implement the monitor-specific pixel packing. Since this approach is display specific it will not be covered by this paper.
I personally have never run across any application using higher than 24 bit color over DVI, and no commercial displays I am aware of support more than 24 bit color over DVI.
I used to work for an Intel Embedded Alliance system manufacturer and display support was one of my pet peeves. I used to talk directly with Intel's Embedded Engineering team concerning display support issues (like this) that our customers would encounter.
Don't your Eizo CG displays have DisplayPorts?
