The trippleheadtogo doesn't support HDCP, and I also found out the cinema display also doesn't. Unless they update the tech I won't buy either 🙁
Got a tip for us?

Will the Macbook Pro run 2x 23" Cinema displays?

Blame DVI!
The problem is not the TrippleHead2Go, nor the Apple Displays - the problem is DVI!
DVI by definition does not support HDCP.
You will need HDMI or DisplayPort for that. That's exactly why those two standards were invented.
And this is why I keep saying that Apple's monitors will need to be updated to DisplayPort the moment any Mac comes with BluRay - since none of their current crop has the ability to support HDCP.
But that has nothing to do with the TrippleHead2Go. Since it doesn't have a DisplayPort it won't ever support HDCP. It can't. DVI doesn't support it.
Hey, that's perhaps asking a bit too much! 😉

Sorry to rain on your parade but that is 100% wrong. It is possible to have HDCP over DVI.
Here is just the first monitor I found claiming this capability. There are many more.

And yet, somehow, my Toshiba 35" CRT HDTV can show Blu-Ray content sent to it's DVI input... 😉
Seriously, DVI does indeed support HDCP. 🙂
I do wish the MacBook Pro had a DB-59 connector to allow two displays. Has anyone heard of a DB-59 to dual-link DVI cable so that you could run two single-link DVI monitors or one dual-link DVI monitor.
Guess I am forced to ante-up the extra grand and buy the Gateway 30" instead of the Dell 24" for my MBP. 😀

It would need hardware-level graphics card support as dual-link is not the same as 2 screens, 1 link each. Never heard of a card (or cable) that did it.

I'm sorry, but what does HDCP matter on a current gen MBP since it doesn't have a Blu-Ray drive anyway? And if you buy an external, there's no playback software (that I'm aware of) unless you boot into Windows. If you're going to be adding on external monitors and Blu-Ray drives, what's the point of a laptop anyway? You seem to be asking for way more machine then what the MBP is.
This post is correct, DVI can support HDCP, and my Macbook Pro works just fine with HDCP on both my Infocus projector and Dell 24" in Windows XP.
Question regarding Triple Head To Go
Sorry to jump in here guys, but you seem like the people who might know. I have a new MacBook Pro that I hooked up to a Matrox THTG and three 23 inch Apple Cinema Displays---the computer seems to think it is a dual head to go and only uses 2 of the the three screens? I have no clue what to do.
Thanks

Do you have the digital on analogue version? The specs make it clear that the maximum resolution pre-screen for 3 screens on the analogue version is 1280 x 1024. It also makes it clear that with the digital version 3*1680 x 1050 only works on XP and Vista, not OSX...
ACD and Matrox THTG
Thanks,
I have the digital edition. Spoke with Matrox. Supposedly it's not the operating system as one just uses the GMX software for Mac supplied with the THTG:
"Systems operating under Mac OS® X must download the GXM Control Panel to access all DualHead and TripleHead resolutions"
Apparently the problem (and I'm sure I am not doing this explanation justice) is that the ACD have some kind of "fixed format" for resolution--unike virtually any other monitor, so the Matrox prodcut detects its an ACD and can only run two of them instead of three. (Not that I honestly understand all of this--but at least I won't beat my head against the wall trying to get it to work. I guess someday I will get a real computer and a graphics card that can run three 23 inch ACD----ANY SUGGESTIONS??
Cheers
