Thank you all for your valuable tim and replies.

I’ve got a new question: if I use a Nvidia Quadro on an external Mercury Helios via thunderbolt, which BlackMagic item would be best?

Thanks in advance.

UPDATE:

Just read on RedUser forum:

“The monitor (i.e. EIZO CG275W) can display 10bit from the DisplayPort interface. However you’re not going to get that at this time from a Mac and a Thunderbolt port as the Mac GDI does not support 10bit output, regardless of what type of interface or connection is used. If you want 10bit displayed on this monitor, you need to feed it with a true 10bit source — which means something from BlackMagic, AJA, Matrox, etc.. that has a displayport output.”

Well, I have no reason not to believe this guy (Jeff Kilgroe), as he’s a moderator on RedUser, but I get intrigued how would the I/O card pull that 10-bit from thunderbolt if the macbook cannot output it?

And then again: IF thunderbolt CAN provide 10bit signal to the I/O card, could this same signal go straight (without I/O card) to a calibrated grading monitor to come out as a perfectly accurate image?
