Official V3 HDMI Board Thread

[andyman]

Has anyone had audio issues ? Cycling through the modes,. I only have four I believe. Stereo, all stereo, direct and auto. Only getting PCM 5.1 or 7.1 while watching DD or DTS

[wilburthegoose]

andyman - Yep - I'm having the same problems - the option to choose DTS or Dolby Pro Logic are gone.

Have you reported this to Emo? If not, please do.
Installing my board tomorrow with everyone out of the house but me.

I've updated my Oppo UDP-203 to the latest Public Firmware released today(link below). I've also updated the XMC-1 to v5.1a. As I've always preferred, I've set the Oppo to output HDR with a Color Space of BT2020 YCbCr 4:4:4 12bit and the XMC-1 is reporting exactly what the Oppo is sending(ie: 2160p/24 12bits, YCbCr 4:4:4 HDR).

Yep... I get exactly the same results even though I have all video output settings in my 203 set to “Auto”. The Oppo seems to be working perfectly with 5.1a. Now if they can only get the flaky HDR responses from the ATV 4K figured out, everything I use on a regular basis will be perfect...

Fired off an email this morning, will report on any advice 

[wilburthegoose]

FYI - 5.1a solved my Chromecast issue.

Only two open items for me now (and I have zero concerns they'll be resolved):
1. DirecTV HLG HDR not working
2. No ability to choose DTS or Dolby Pro Logic audio

People, adding color bits (example: going from 4:2:0 the bluray standard to 4:2:2) requires a huge jump in bandwidth.
It is NOT surprising to see so many "bad" cables before and after trying to push this much data.

Here is a chart:



As you can see 4K@60 with 4:2:0 color requires ~9 Gbits of BW.
Just changing the color space to 4:2:2 requires 2X the amount.

No wonder so many "bad" cables are popping up.

Some light reading on HDR and color depth.

And an online bitrate calculator:

4K dolby vision blurays require 13.3Gbits. Why? Blurays are 4K@24 vs 4k@60!

My advice:
Find out what your display's native format is (vs upsampling capabilities) and try to match that across sources and most importantly your source material.
(Why push 4:2:2 if you only get that via the displays internal streaming app for example)
Try to avoid unnecessary upsampling if you can so as to not push unneeded data though these god forsaken HDMI cables.
Of course since HDMI is the work of the devil, go buy new HDMI everything when another spec comes out.
After all that is why we have HDMI in the first place. Big OEMs have to eat and sell product to the masses every six months.

I know we are all giddy turning up the knob to 11 on our color space, but we are "blowing up" our cables doing so.

Bingo! Was going to suggest this, but due to excessive debt, I don't even have a 4K display yet, let alone handy links and charts and full-color glossy photographs with the circle and arrows on the back of each one of them showing the site of the.... ummm, well you know what I mean.

Snippet from article about cables:

HDMI Cables
For short runs (say up to 6′ / 2m) most passive cables will be able to support the data rates required for UHD. Between 6′ and 15′ you’ll find some passive cables that can support UHD and others that can’t. Above 15′ you’ll very likely need an active cable.

HDMI Premium Certification

There are a few independent companies that are providing HDMI cable certification for UHD data rates. These include:

HDMI, “Premium Certified Cable”, at the 18Gbps rate
UL Lab, “High Speed 4K Cable”, at the 10.2 and 18 Gbps rates
THX DPL Labs, “DPL Seal of Approval”, at the 10.2 and 18 Gbps rates
HDBaseT (HDMI over category cable) is capable of data rates up to 10.2Gbps.

Agreed... this is a good article which I’ve read in the past and has helped my understanding as well.

Make sure to read the “comments” as there is some very valid information in them. HDMI.org has made some confusing “running changes” to the 2.0a and 2.0b standards that makes the charts in the main article showing what “legal” formats are supported to be partially incorrect. Those charts (and some of the content) really needs be updated.

While we're on the subject of specifications and background info, HERE is a link with great info, some of which was updated this month.

This hobby is going to kill me. So upgraded the XMC-1 to V5.1a and at the same time the Oppo 203 updated to latest Public Firmware and after that no video at ALL on the 4K LG Monitor. I can get 4K HDR from ATV 4K but not from the 203. Then switched to the 50' Monoprice HOSS active cable and got the 203 working again. I just went to my office were I had the same Media Bridge 35' HDMI cable, plugged into the 203, well nothing, just flashing screen. I was running the beta firmware until tonight and after the public firmware the 35' Mediabridge HDMI cable is not woking anymore with the 203. I almost go crazy figuring this out. Can't believe that a simple firmware update can make a HDMI cable not working anymore. It does pass 1080p, but not 4K from the Oppo. Weird things happens!!!

Sounds like Oppo may have tweaked the HDMI driver, which could have included EQ changes in the internal transceiver, so it no longer "likes" the longer cable? What a PITA... I imagine the next time I power up the Oppo (today, hopefully) it will update; now I have to hope something does not go kablooey. I also plan to switch from using XMC-1's HDMI 1 to output 2 since that seems to be the best choice, and will switch to input 2 (also ARC though I do not use ARC) on the LG C7 at the same time. Then on to reprogramming everything to use the changed I/O ports...

I have all sound modes available while watching DD, DTS or Stereo. If I have it on AUTO It goes to Dolby Pro Logic II Music.

Update on the 35' Mediabridge HDMI Cable: Forced the Oppo 203 to UHD 24Hz and it does pass 4K/24Hz 12bit 4:4:4 HDR. If I switch to AUTO then video is gone because the 203 switch to 60Hz on the Home Menu. I had it on AUTO before and it was passing video @60hz, not anymore. At least I know if I set the 203 to UHD 24Hz it works perfect. Either way I'm changing the cable with a 35' Monoprice HOSS Active HDMI Cable that I got on Amazon for $20, the same cable is $60 at Monoprice.

Turned on the system this morning to see how things are working. No Audio at all from any sources. 😩😩
Turned off rocker switch on back of Xmc and I have sound again.
Are the majority of you guys in low power mode or video remains on ?
Still only certain sound modes available to me , no DD or DTS .

[donh50]

Video remains on for me. I have had to power cycle the XMC-1 maybe 2-3 times in the three years or so I've owned it. Vexing, but no more so than having to reboot my PC at least once a week or so. Hopefully your experience was a one-time glitch.

Have to check the sound modes this afternoon assuming I get a chance to play with it.

Curious: I read here that HDMI 2 was the primary output so am planning to switch to that one just because, but noticed in my XMC-1 manual (v30) it states that HDMI 1 is the output that has CEC and ARC. Did the primary output change from 1 to 2 with this new board? And are both outputs always active?

Yes, the “primary” output is now HDMI 2 on the new board (and is labeled ARC on the replacement port overlay). Lonnie mentioned this earlier in this thread, but after this many pages it’s certain to get lost in the mix. The manual will need a few updates for sure.

Both HDMI outputs are active and HDMI 2.0b compliant.

Yes, they changed it with the V3 Board. With the New V3 Board, primary output (ARC) is HDMI OUT 2 (check the V3 Board add-on label).
