Bob,

Matrox's P750 Millenium Digital Imaging Datasheet, available here on the

http://www.matrox.com/mga/products/tech_info/pdfs/general/digital_imaging_da
tasheet.pdf

Says that the board uses a 10 bit Digital to Analog (DAC) circuitry. Not the
same thing as having 10bit video RAM frame buffer.

This is an excerpt from page 2 of that PDF:

> Ultrasharp Display Output Technology
> Matrox offers the industry¹s highest-quality analog, digital and TV
> output through 10-bit DACs and an advanced board design for
> exceptional image quality.

This is not to say that Matrox, like ATI and the other video board makers,
is not busy engineering 10-bits video RAM boards. But I don't have any
information to that effect.
