Please tell me the quote below from the CNET review of the Vizio P series 55 inch is NOT accurate.
"Like most 4K sets, the Vizio P series can't accept 4:4:4 chroma subsampling signals via any of its inputs. The company claims that's because three of the ports are compatible with HDCP 2.2, which doesn't allow 4:4:4 signals. This isn't a big deal to us since, once again, the only common 4:4:4 sources come from PCs."
Does this mean that HDCP 2.2 (HDMI 2.0) has a requirement to NOT include Chroma 4:4:4 at 4k60z?
I know that the Vizio P series can accept 4:4:4 1080P@120hz but not 4k60z, the question is why? If HDCP 2.2 is the problem then Displayport is most assuredly the future for everyone on this forum.
"High-bandwidth Digital Content Protection can be used to secure the transmission of digital assets, be they broadcast or media. Without a device-to-device handshake, HDCP 2.2 delivered content isn't going to make it onto any screen. Unfortunately HDCP 2.2 chip availability is trailing behind 4K product roll-outs.
Chris Pinder heads up HDConnectivity, video distribution specialists for the custom install industry. "Yes I see trouble ahead," he confided to me. One complication is backwards compatibility, he says. "An HDCP 2.2 device would not work in the mix with any (currently available) HDCP 2.1 (and below) TV or sources. Everything has to be 2.2."
Pointedly Pinder points out that the likes of Sky may actually have no intention of implementing HDCP 2.2, simply because the chipset would not only drive up the cost of any new HEVC Sky box but limit compatibility with available 4K displays.
Conversely, a 4K Blu-ray player could circumnavigate the HDCP 2.2 headache by offering two HDMI outputs, with one going directly to the screen (which would then also need to be HDCP 2.2 compliant). But we could speculate until we go 4:4:4 blue in the face.
If all this is all beginning to sound like a hideous mess, that's because 4K UHD's standards are a hideous mess"
For example: http://www.cnet.com/products/samsung-un65hu9000/
go to HDCP 2.2 in the article.
Apparently the SiL9679 chip being used by TV manufacturers for HDCP 2.2 support over HDMI 2.0, the only such chip available currently, is only capable of up to 4:2:0 chroma at 4K at 60 hz. Anyone looking for full RGB color at 4K60 on a TV should try to find one without HDCP 2.2 and hopefully using another chip, if this is the case.
