Anyone got a 4k TV/Projector yet?

HDCP, content protection has also been changed for the 4K standard. You will need HDCP 2.2 with 4K protected material. All the displays and projectors will have HDCP 2.2 for Ultra HD material. So even though, Display Port can transmit 4K, the current generation will not have the correct HDCP 2.2.

Well films are only 24fps anyway, so they don't even require HDMI 2.0.
60Hz is only required for hooking up a computer to the display, and HDCP is generally not important there.

HDCP is only relevant for consumer hardware and 'official' software like TMT and PowerDVD. MC, LAV filters and MadVR couldn't care less about HDCP. (thanks to madshi and hendryck for making this possible).
Upscaling SD 50/60Hz stuff to 4k 50/60Hz would be the ultimate goal! Would the Nvidia Titan have the necessary grunt I wonder? I'm sure we'll see a DisplayPort to HDMI 2 converter capable of 60hz 4k soon.

I guess GPU with 4K 60Hz support via HDMI 2.0 should be ready soon. There is no diplay port on this projector.

I assume the 4:2:0 limitation at 4k 60Hz is a bandwidth limitation for HDMI.
Although I assume that 4:2:0 at 2160p should be better than 4:4:4 at 1080p?

Does not matter, if it's 24fps or not. 4K material, most of which will be at 24fps is going to require HDCP 2.2 to get a picture. Older GPU are not going to work for 4K into the new displays with current version Display Port. The 60Hz is irrelevant really if you can not even get a picture to show at any frame rate for 4K material. Because HDCP has been "cracked" the new sets require HDCP 2.2 to display any 4K material. It's backwards compatible with HDMI 1.4 so you will still be able to display lower resolution material.

How are you going to make the display show a picture if IT requires HDCP 2.2 to show a picture.The current version of DisplayPort appears to be unable to transmit 4K into the new displays not because it is incapable but because the display will require HDCP 2.2. An adapter will be useless in this case.
