I looked at the Sony spec sheet for the 850A and it specifically calls out HDMI 2.0. However, the 850B spec sheet does not even mention what version of HDMI it supports.
The HDMI Forum appears to be pushing all companies to stop quoting HDMI specification revisions in their marketing materials, and instead to advertise the specific features that are supported by a given device. Not all devices will support all modes of transfer, and so the overall "HDMI 2.0" label is a bit misleading.
For instance, on page 14 of the Operating Instructions/Setup Guide that came with my set (Document code 4-533-569-13
(2)), there is an interesting note on page 14. This note says to connect 4K devices to the HDMI IN 2 or HDMI IN 1 jack to enjoy copyright protected content. That's a notable little detail that I'd not discovered until I started looking because of your post.
As paul.sim noted, the X850B family supports [email protected]
with YCbCr 4:2:0 8bit encoding only. The HDMI 2.0 spec also defines modes with YCbCr 4:2:0 16bit, YCbCr 4:2:2 12bit, and YCbCr 4:4:4 8bit as well; the X850B family doesn't support those modes.
So does the X850B family support every single display mode defined in HDMI 2.0? Nope, it doesn't. Does it support some of the modes defined in HDMI 2.0 and, therefore, have HDMI 2.0 ports? Yes, I say it does.
The HDMI Forum's Consumer Buying Guide has a pretty good answer here: "Some people have the mistaken idea that they should be shopping for a particular version of the HDMI Specification, for example, HDMI 1.4. This has never been true. Instead, you should shop for the specific features you want, and make sure that those features are supported in all the HDMI devices you will be using."
If deep color in 4K or [email protected]
mode is important to you, then go ahead and return your X850B. Given these sets feature SONY's Triluminous display panel, that could be an entirely reasonable expectation. As I read the specifications, though, these deep color modes are supported in [email protected]
/25/30Hz), and in 1080p and lower at all supported refresh rates.
