Anyone got a 4k TV/Projector yet?

So far because your current GPU is HDCP compliant, you can send any resolution you like with any player that you like and not have to worry. DisplayPort can be updated but that always requires new hardward. Hardware that you don't have in the current GPU.

4K resolutions do not require HDCP 2.2 - only protected content requires HDCP 2.2 support.
You can hook up a computer to any of the current 4K displays via HDMI 1.4 and display 4K at 30Hz, or 60Hz using DisplayPort/HDMI 2.0

As I understood it, programs like AnyDVD remove AACS protection from the discs, which allows them to be played in any media player.
Players like PowerDVD are required to enable HDCP when playing back AACS protected content - the content itself is not HDCP encrypted.

The material that one is going to want to watch is going to be the protected content. No currently released 4K projectors have display port. No current Display Port to HDMI adapters are capable of transmitting 4K because they were designed with the HDMI 1.4a spec. My suggestion is to just buy new GPU instead of waiting or hoping for projectors to have Display Port. Display port has very limited penetration in home theater. HDMI 2.0 will be present 100% of the time with new 4K projectors. Display Port will not be and again currently is not present on any.

Blu-ray is currently protected content, and there are plenty of ways around that.
Using PCs for playback, AACS is removed, which bypasses HDCP altogether, because you're effectively playing "unprotected" content.
We won't know until there is actually a 4K format being produced, but there's a high likelihood that HDCP will not be an issue for PC-based playback.

There are 4K displays which have DisplayPort, though you may be right about there being no projectors with it. But HDMI 1.4a is sufficient for 4K at 24Hz and 30Hz, which is all anyone needs for film/tv content. 60Hz is really only necessary for PC use.

HDMI 1.4a supports 4K at 24Hz and 30Hz. HDMI 2.0 adds support for 60Hz—which DisplayPort can already do.

I don't expect them to move to using DisplayPort now, but anything with DisplayPort 1.2 will be able to output 4K60 via an HDMI 2.0 adapter.

I guess. Adapters have given me a lot of problems. I try to avoid them when possible. With the new AMD GPU, it's one hassle with which I will not have to bother. Again,no current HDMI adapters will transmit 4k. Perhaps it's my perception but adapters always seem to lag in development and usually are a kludge. I suspect the AMD GPU will be released much sooner than the adapters. DisplayPort will likely be included on higher priced models at some point, but again you'll be waiting. Connections that are not in wide use, raise the price but do not add much value to lower priced consumer electronics where HDMI dominates. DisplayPort's main value was that it could do things that HDMI could not. I don't see any value for myself personally now that HDMI can transmit everything that it can and perhaps more with audio and it's 32 channels capability.

Looks like Panasonic are including DisplayPort 1.2a on their new 4K displays: http://av.watch.impress.co.jp/img/avw/docs/617/533/html/pana09.jpg.html
