Not true... because of YCbCr 4:2:2 sub-sampling, 12-bits YCbCr costs
as much bitrate as 8-bits RGB 4:4:4. And then 165 MHz pixel clock is
still enough for 1080p resolution, so a single link will do.
Note that ATI are saying that all their X1000 (1300, 1600, 1800) cards
have dual-link DVI output, and full 10-bits processing in the output
path, and that they can actually connect to a 10-bits (or more) digital
display. This is the first good application of dual-link that I have
heard of. But you need this only for RGB, not for YCbCr.
Best,
