I plan on getting the new Apple TV that supports Dolby Vision output - will I be able to use it with the MC-700? I see that many receivers are getting firmware updates that enable Dolby Vision passthrough so I'm curious if this capability is on the roadmap.

Added to the no OSD on the 4K inputs is pretty much a deal breaker for me on the MC-700. Cheers Gary |

The Menu screen will pop up if you're using a 4k input, just the "Info" and volume pop-ups won't happen. Of course when the Menu screen pops up, the video and audio go out like you just changed source. I'm pretty sure all that is missing is just the volume pop-up and Info (and the "info" from Info isn't very useful) - anyone know of any others that are missing on the 4k inputs?

Looks like the Outlaw 976 will come with HDMI 2.0b firmware, which is what is required to support Dolby Vision and HLG. If you don't plan on doing this for the MC-700 I'd at least request you put in on the roadmap for the Emersa EMP-1 to keep the new product competitive. I'll have to pick up either of these to make the Apple TV work. Support for Dolby Vision is not planned for the MC-700 at this point.

According to the Dolby website, Dolby Vision dynamic metadata can be embedded in a video signal and passed through HDMI 1.4b, but because most Dolby Vision content is in Ultra HD and requires HDCP 2.2, this is only available on HDMI 2.0 and up. So since Dolby won't define a necessary HDMI version requirement, I'm led to believe this is license/software driven and not hardware driven. You also mention the new Apple TV 4K, this is spec'ed at HDMI 2.0a according to the Apple website. You say "the Outlaw 976 will come with HDMI 2.0b, which is what is required to support Dolby Vision", then how does the new Apple TV pass Dolby Vision at HDMI 2.0a??? Confusing at best right? Thus pinning down requirements for Dolby Vision, with all the information available, seems to be elusive at best. |

But the real problem is my ATV4K will be here on Friday and there's no Emotiva processor to process it through  Cheers Gary |

Just received my Apple TV - Dolby Vision 4K @ 24Hz works just fine through the MC-700.
For HDR10 only 4:2:0 chroma works at 60Hz - 4:2:2 fails. Its good news either way - no need to be changing pre-pros this soon.

For me, 4K works fine at 60 Hz, but HDR only works at 25 & 30 Hz. The colors look subdued and horrible, really. SDR @ 60 Hz is night and day better. I just bought the MC-700 because I thought it would support 4.2.2 @ 60 Hz. Very bummed.
EDIT:
I bypassed the MC-700 and went straight from ATV to TV. Same results. It's not the MC-700's fault. This TV was not originally planned as an HDR set, with that feature coming by firmware update. It could be that it is not a good implementation or that Apple's HDR flavor is not liking it. According to reviews I've read, HDR Bluray's play fine on these Vizio's with HDR by way of firmware update. My mileage varies from this significantly. I would rather have 4K/60 with SDR than 4K/30 or 1080p at HDR. The Vizio's have multiple HDMI inputs, with only one of those being a 4K/60Hz port, which from what I read is HDMI 1.4 rather than 2.0. The other ports are HDMI 2.0 but do not support 30Hz. That could be my problem.
In any case, the 4K/60 picture is lovely and I am only sacrificing HDR at this point, which is fine. MC-700 is working pretty well otherwise. I don't have a problem with weird pops or drop outs. Sound quality is good but I haven't done the Emo-Q calibration yet. It is replacing a UMC-1 that I was very happy with from an audio standpoint. I would not have changed it if it did 4K.
MC-700 on screen menu is as bad as I've seen. It feels like alpha software at best. Hopefully Emo will keep working on it and one day we'll have something decent.

This is why available 4K sources are having 4:2:0 upsampled to 4:2:2, which then passed to the display to upsample to 4:4:4. This is done so that reliance on HDMI cables with limited rates of up to 10.2 or 18Gbps will be able to pass the audio & video info without having problems. Check out the tables below and the link article as well, lots of good information on all of this. Personally the Emotiva Z-Series HDMI cables I'm using are passing upsampled 4:2:0 content from UHD blurays to 4:4:4 from my Oppo UDP-203 straight to my display without problems which is at least 18Gbps, so while they are not certified "Premium" by the HDMI organizataion, they would definitely pass for "Premium" if officially tested. www.acousticfrontiers.com/uhd-101-v2/  |

So maybe the combination of hardware and/or software just so happens to work for passing the Dolby Vision metadata? Just venturing a guess here.  |

It may work, but if it doesn't (or it stops working) they aren't going to help you to get it to work because it's not supported. |

Nice try, A for effort, but I read "supported" as meaning "allow the use or operation of", hence "not supported" therefore meaning "doesn't allow the use or operation of". Perhaps KeithL can elaborate on what exactly he meant by "not supported" because it would seem that the MC-700 does in fact allow the operation of Dolby Vision? Cheers Gary |

Its interesting that anandtech says that HDMI 2.1 is more to bring up HDR standards to higher resolutions and frame rates ; something that hdmi.org is keeping close to its chest with contradictory HDR info as its not finalised yet..
Makes me wonder if any of the denons/Marantz that got the DV passthrough upgrade were a similar vintage and its all connected with Dolbys very clever non separate metadata but buried in the signal method .. Could HDR10+ use the same method ? Wish there were a few such discs now.. Incidentally I don't like +;s chances if it has to wait for hdmi 2.1 to turn up..

You can read it however you want but inventing your own interpretation isn't going to make the standard definition that is used in the industry different. Not supported means it may or may not work; they provide you no assurances nor assistance in getting it to work or keeping it working. If it works for someone, fine, if it doesn't work also fine. I give you an A for imagination. |

You invented the notion that an Oxford dictionary definition is going to supercede standard industry terminology. I don't know what industry you are referring to but I've been involved in professional audio for over 40 years and when we talk about hardware (eg; an MC-700) supporting software (eg; Dolby Vision) then there is no other definition possible. If you were referring to Emotiva supporting Dolby Vision conceptually in the broader sense then you could argue your case. But that's not the subject of this thread, it is directly "MC-700 support for Dolby Vision passthrough". Cheers Gary |

Its good news either way - no need to be changing pre-pros this soon. That info would be enough for many vik ; its a moot question now as it works you found . Its as many oppo owners know ; capabilities may surface without any mention of official support ; as ISO file playback was stumbled upon to the delight of many once  And full bdmv folder playback as well before it disappeared due to studios copy protection biases..  Not to mention the "experimental" nature of the oppo 83's file playback capability at an earlier time . Oppo at the time didn't have any say on what file codecs they could playback ;though they wanted more and got them with the next gen ; they are at the mercy of the oem chipset supplier and its coding.. as is emo. Keith may elaborate more ? |
