Well I got caught up reading all the other posts to this thread and it seems like I'm not the only one having color space issues with Dolby Vision on my Apple TV 4K to LG C7 TV. The front panel is occasionally saying RGB 4:4:4 SDR, and sometimes RGB 4:4:4 HDR. I am also seeing it always show 2160P/60 8bit. I am really hoping a firmware update will resolve this.

The only way for me to test DV is with my bedroom TV (Sony X930E) which is about 40' from the XMC-1. I did try connecting my Sony TV and XMC-1 with a 50' Monoprice HOSS Active HDMI cable and the ATV 4K did detect DV and switch to DV but colors looked washed out and the XMC-1 and TV showed SDR. So it must be the HDMI cable. I'll be ordering on Monday an Emotiva 4K HDBaseT HDMI Extender and I will report what my results are with DV and the 4K HDMI Extender. According to Lonnie it shouldl work and it's what they recommend for runs more than 10 ft.

I know it's obvious but just in case, when the XMC-1 is inserted between the source and the TV there is an extra HDMI cable. As a result connecting the source direct to the TV doesn't prove that the cables are OK, both of the cables, plus the length of the 2 cables added together.
Cheers
Gary

AH, remember the way back good old days when we just turned on the TV and got picture and sound. May have looked like crap (in the real early days the picture wasn't even in color) and sounded pretty bad, but we didn't know any better and were pretty happy with it.

Well no DV or HDR to test yet, but I’m enjoying the larger OSD, I’m wondering though if it’s because I’m in 1080p. Are those with 2160p getting a larger OSD as well? (actually I suppose you haven’t had an OSD until now)

Everything is installed, set up and working perfectly except Directv 4k channel 104. Oppo 205 is HDR and beautiful. Sony TV has the enahnced 4k settings. Loaded firmware 5.1. Like others still getting black screen on Ch. 104...have double/triple checked settings in all devices. Powered on/off all devices multiple times. Monitoring forum for solution. Thanks in advance!

Also getting black screen on 104. I know some others have this problem as well who installed the board...
I've reported this to Emotiva

(actually I suppose you haven’t had an OSD until now) For me it is quite small and the font color is a darker bright blue (used to be white), making it difficult to read on a dark background (if transparency is off, then it is impossible to read). I have not seen a setting to change color or size. |

But it does prove that both cables are capable of passing the 18Gbps necessary to display 4K60 DoVi, without screwing up the picture. |

I have not seen a setting to change color or size. Go to MENU/SETUP/PREFERENCES and choose a different color theme for the OSD and also select WIDE to make the OSD bigger.  Update: Sorry, looks like there is no more "Color Theme" or "Wide" options with the new V3 Board/firmware? Can anyone confirm this checking in your XMC-1?

It really doesn't prove anything since you are only using one HDMI cable whereas when you put 2 cables together you are doubling the effective length from say 6 ft to 12 ft depending on what cables you have.I could be wrong but the XMC-1 is merely passing through the info and is not manipulating it in any way. Maybe try different cables or get one of the boosters that Lonnie suggested. It behooves me to understand why people ask for assistance and then argue without any facts. I get this at work all the time, whats wrong with my car, i make a suggestion based on 35yrs of experience and then they say Oh it cant be that. Why did you ask me if you already know then? |

Those settings do not exist in the latest firmware...

I have an Nvidia Shield and have some odd behavior. (May have been covered in this thread, I haven't read it up until now). On the home screen, in settings, I seem to top out at REc 709, 3840x2160, 24hz. So with the XMC in the loop, I cannot select a higher resolution "native" on the Shield. If I connect my Shield directly to the JVC RS520, I can select all 4k resolutions, color spaces, etc. I also could select them all when I had a Marantz 7700 in between them, so unlikely to be a cable issue.
BUT... if I go into KODI and play a 4k, HDR video, it outputs 4k, and the XMC says it is receiving 2160p/8 bit RGB 4:4:4:HDR
What may be going on?

You are, in fact, wrong. While I haven’t popped the heat sink off the new HDMI board I’m 100% certain that those aren’t just analog switches passing hdmi through. We also know this because emotiva is compositing their UI overlay on top of whatever is coming in. This is impossible with simple pass through, as you suggest. At some point on this board they are either redriving or retiming the signal. So if the signal eye is closing when it it’s received on an input port, it’s being reopened on the output side. Bad cable + bad cable does not equal worse cable. |

Cheers Gary Even standby passthrough keeps the HDMI circuits powered (hence the reason they call the other mode "low power"). The signal path, active redriving/retiming is the same though. |

I got around to relocating my Chromecast Ultra from my Oppo UDP-203 directly to my XMC-1. I'm happy to report that I'm getting Dolby Vision through Netflix programming casting from my iPhone to Chromecast! Very, very sweet!
