I've been looking at Dell's 24" and waiting for it to go on a $700 or less sale again. Does anybody here have one? How is it for gaming and movies, and do you have anything you don't like about it?
Hmm, looks like it'll only be on the new HD-DVD's, and I'm sure it won't take too long before somebody cracks it. But yeah, I'm not planning on buying on probably until summer or so, just interested on if I should be looking at something other than the Dell.
There have been rumors the past few months about a revision to that monitor family to include HDCP. I would say it will come sooner than the next $700 sale (or likely right before it to clear inventory).
i love my 2005fw as well. Unlike css which was a software thing. HDCP is a hardware thing. I wouldn't expect it to be as easily cracked, if cracking is even a possibility.(with enough time i'm sure it will be)

Well, it's a hardware/software solution that encrypts the beautiful raw video stream pouring out of your DVI connector... so it might yield to hacked drivers on the PC side of things? Check out:
Even if valid hardware and valid keys are present, it might still be possible for an external agent (typically a driver or software application) to interfere. In the worst case, this agent could make it appear that the HDCP hardware is present and active when, in fact, it's not there, not working, or altered in some way. Upstream authentication enables the system to prevent or detect this kind of problem and can also permit the system to move confidential values from the hardware to the software application without fear of the values being observed or altered.
The simplest form of upstream authentication uses purely physical barriers. Many applications have fixed hardware and firmware configurations and are not subject to user-installed upgrades or modifications. The absence of such modifications is typical of consumer-electronics products, including devices such as set-top boxes and DVD players. In such cases, the required security can be established by design, verified by test, and protected by the enclosure and the requisite "no user-serviceable parts" warning label.
A personal computer is completely different, though. Users frequently install their own software and can download new drivers or plug-ins with just a few mouse-clicks. In this environment, upstream authentication combines hardware and software protocols that include encryption and signature algorithms, with the implicit assumption that no driver is trustworthy. Special cryptographic messages that only the software can interpret hide link status and confidential data values. The drivers can only pass the messages along. If the drivers fail to forward the messages or tamper with them in any way, the mischief will be detected.
The original HDCP specification does not define upstream authentication, as it is application-dependent and isn't always necessary. A companion specification defines a recommended implementation for PC applications, however. This specification uses a mathematical system that is similar to HDCP's downstream side. The keys come from a different key space, though, and will not interoperate with the downstream keys.

Well, totally open and free flavors won't be playing HDCP content out of the box. I wouldn't be surprised if Novel, Red Hat, Mandriva, etc. ask for licenses... in which case, Linux HCDP stuff might be released (I'm not entirely sure if it would be legally wise to refuse to license them).
I say it's only a matter of time until HCDP details leak and someone starts emulating HCDP hardware... after the first generation of hardware is in living rooms around the nation.
