    No HDR with Onkyo TR-NX646 and Epson 5040ub (4k / 24hz / YCbCr 4:2:2 24 bit)


    I have an Epson 5040ub projector that support (faux) 4k and HDR. I have it connected to my Xbox One S through my Onkyo TR-NX646 (AVR). In this configuration, I cannot get HDR to work from the Xbox. If I connect the Xbox directly
    to the projector I can enable HDR and it works correctly. If I plug my Xbox into the AVR and to a different 4k TV with HDR, it also works. The Epson requires YCbCr 4:2:2 12 bit to display HDR (it cannot support faster refresh rates). When I have everything
    connected and open the Blu Ray app, the AVR and my projector report YCbCr 422 24bit so the Xbox is capable of, and is, sending the correct signal through the AVR to the projector. For some reason, the settings app on the Xbox won't enable HDR. FWIW, I also
    noticed that when I switch 24hz support in the Xbox Settings app, it outputs RGB and no YCbCr during the test before it commits the change. Any help on how I can resolve this would be greatly appreciated!

    Xbox One S HDR UHD and Netflix Playback.

    Hey Miss Bijoux,

    If I turn off "Allow HDR" then the content plays as normal. The washout only happens during HDR video playback and nowhere else.

    I contacted LG support on this after some investigation on my own. I noted that by checking my signal on the receiver HDR video playback on the Xbox One S is 10-bit RGB at 24Hz.

    All other devices I've used seem to use either 12-bit YCbCr 4:2:2 60Hz (PS4) or 10-bit 4:2:0 60 Hz (HDR Blu Ray Player) for their HDR content. LG Says they don't support 10-bit RGB.

    Now here's where it gets interesting. HDR Games on the Xbox One S come through at 10-bit YCbCr 4:2:0 60Hz. So I tried disabling the 24Hz signal in the Xbox One S.

    Now it puts out a 10-bit YCbCr 4:2:0 60Hz signal when attempting to watch HDR video... but the dimming issue still persists.

  3. xbox one s does not support 4:2:2 hdr!!!

    Xbox one s only supports hdr game with ycbcr 4:2:0 while playing forza horizon 3. It should support ycbcr 4:2:2 4k 60Hz as well for better picture quality.

    Having the same issue, Epson 5040ub w/ Xbox One S, HDR isn't working on anything (UHD, Netflix, games) despite receiver and all cables being HDMI 2.0a / 4K HDR supported spec.

    Ycbcr support for 1080p/4k bluray playback

    i noticed the same when watching 4k ultra blu ray hdr movies 24hz setting on. X box one x outputs only rgb and picture is a mess with my optoma uhd65 projector. You need to fix it output ycbcr on 24hz setting on too!!

    If i unselect 24hz x box outputs 60hz ycbcr and picture is pretty good.

    Xbox One S and Epson 5040UB

    Exactly the same issue. I have the Epson EH-TW8300 which is the Australian model number for the 5040UB. Tried through my reciever and direct connecting to the projector with multiple HDMI cables. Tells me it's 4k and HDR compatible but has the yellow exclamation
    mark for all of the 10-bit points and says my TV setup isn't compatible with 10-bit. It's weird that it has the tick for HDR compatible even though all the 10-bit stuff says it doesn't work, and no HDR gets output to the projector.

    Xbox One S and Epson 5040UB

    Hey all,

    From the research I've been looking at, these projectors don't appear to be using Native 4k over HDCP 2.2 and HDMI 2.0a It looks like the projector will accept a 4k Signal, but then downscale it to 1080p. This looks like the reason for it not working properly
    for you on the Epson 5040ub, EH-TW7300 and 6040ub.

    We'd recommend reaching out to Epson for further clarification on if the Projector displays in True 4K while using HDR.

    If it doesn't, than this would be the reason that 4K Blu-ray UHD discs are not playing at a 4K resolution and only at 1080p.
