I'm new to this particular group and hope someone can provide some
guidance.

I'm looking for video cards and displays that can support greater than
24-bit color depth (8-bit per RGB color channel) over a DVI interface.
In particular, I'd like the video stream be sent over the digital
portion of the DVI cable as opposed to the analog portion (I am not
referring to an analog VGA cable).

Does anyone have suggestions for vendors, dealers, or websites to
contact?

For more details please see below:

I need to put together a workstation to support high-color precision
scene generation. My job is to put the hardware together, other people
will be handling the CG scene generation software.

I know that current generation GPU's are capable of handling high
numerical precision (e.g. floating point) data within their pipelines,
including color/shade info. The pixels coming out of the pipe are then
dumped off the board at lower color precision, either 8 or 10-bit per
RGB channel. Most high-end video card specs are calling out triple
10-bit DAC's, so that implies 10-bit per color channel data is being
transmitted either thru the VGA cable or the analog portion of the
DVI-I cable. However, I don't know if the 10-bit per color data is
available over the digital portion of the DVI-I cable (which is what I
need). This would depend on whether the video card vendor is utilizing
their TMDS transmitter's second link in their DVI interface
implementation.

Likewise, on the display side, I need a display that can handle 10-bit
per color RGB using the DVI digital link. If you've read this far, I'm
sure you will be thinking that usually only LCD displays will come
with a DVI interface, but LCD's usually have inferior dynamic color
range compared to CRT's. I know this is ironic, but this is what I
need for our system Your feedback is appreciated.
