PS4 has HDMI 1.4a, same with Xbox One. As has been stated, HDMI 1.4a bandwidth can support native 4k playback @ 24Hz full dynamic range, or 50/60Hz @ 4:2:0, 8 bit (i.e. - limited dynamic range) if said device is capable of a firmware upgrade to support these features, good article here
explaining which manufacturers have stated such upgrade support so far.
I think this is were some people are getting confused: they see 4k support listed at certain resolutions/dynamic range and assume this must mean said device is HDMI 2.0.....AFAIK
at this moment Panasonic is the only manufacturer with TRUE HDMI 2.0 capable chips. The touted "HDMI 2.0 support" of the 600ES and even 1100ES is not TRUE HDMI 2.0 support (i.e. - they cannot handle the full 18.2Gbps bandwidth that HDMI 2.0 calls for so therefore cannot handle the full 4k dynamic range at 50/60Hz or even suggested future rates of 120Hz for TV based content/games).
I would break it into two easy parts:
A) Said device is capable of pseudo-HDMI 2.0 support (50/60Hz @ lower dynamic range, like the Sony projectors, PS4, Xbox One, or other firmware upgradeable displays/devices)
B) Said device is TRUE HDMI 2.0 support (50/60Hz @ full dynamic range, like the Panasonic TX-L65WT600)
The PS4 is using the Panasonic MN86471A HDMI chip (one of many sources for this info is - HERE
). Photo from inside the PS4 is shown below:
According to several online sources this is a HDMI 1.4b HDMI transmitter chip that only supports 4K video at 24Hz and 30Hz. According to the Panasonic press release (HERE
) their full bandwidth HDMI 2.0 chip has a different part number. I did do a search on the Panasonic semiconductor web site, but could find no listing for the MN86471A HDMI chip used in the PS4 so I don't know on what basis some online reviewer's/bloggers have determined it is a HDMI 1.4b chip, other than the PS4 currently is spec'ed to only have a 1.4b HDMI output.
Perhaps the MN86471A chip is being made by Panasonic specifically for Sony to use in the PS4 (that appears to be case) and that's why Panasonic does not list that part number on their web site. As a side note the PS3, when it was introduced in Nov. 2006, used a HDMI chipset from Silicon Image that was a custom product only used in the PS3 and not listed on the SI web site nor sold by SI to other manufacturers, These SI chips were HDMI 1.2 certified but with the hardware for certain of the features for HDMI 1.3, which Sony later enabled with a firmware update to the PS3. I'm not
claiming to have any info that we have a similar situation with the Panasonic HDMI chips being used in the PS4 (i.e., with some HDMI 2.0 features being supported), but unless we can locate definitive info on the capabilities and limitations of the MN86471A chipset then it cannot be ruled out.
Has anyone on AVS forum seen any spec. sheet or other definitive info from Panasonic to confirm what the MN86471A capabilities (e.g., HDCP version) really are? What is clear it that the PS4 does not use the same HDMI 2.0-lite chipset used in the VW500/600 or the VW1100. It seems to me the jury is still out on the technical possibility of the PS4 getting a future firmware update to support the 4K download service and/or playback of future Blu-ray 4k discs.
