Yamaha RX-A820 4K + HDR

mtv · 28 January 2019 09:17

HI,

my last week received 4K+ is working fine, better then my h96pro+ CoreElec. Now even 25FPS is played in 4K. perfectly to my TV.

Vero4K+ -> RX-A820 -> 2018 Q9FN

video settings on RX-A820 set to direct ( the processing option and then choose for through, doesn’t make a change"). GUI vero/kodi in 1920/1080p 60 and start/stop for 4K output and all sounds work.

Now I choose a testfile from Kodi site and a LG test file, to see if HDR is working. With LG test file (4K 60P HDR)

What i discovered, that HDR icon only pops up when connected Vero directly to TV, but recognize the file as 1920/1080p 60P and HDR.

putting VERO back to AVR, file playes perfect, 1920/1080p 60P and without HDR.

I tried another file and HDR is only “activated” as put directly on TV.

Now i’ve read many articles here on changing extra settings (HPD Lock, 444 etc, putting TV in UHD mode on selected HDMI channel to activated 444). but i’m not sure if my receiver is the blocking factor here.

Read things about Denon receivers not being able to do it all well, and also mixed stories about Yamaha 1080/1070/870/880 receivers in HDMI mode 1.

Does someone has the same receiver (rx-a820) and vero4k+ and is able to play most of the files and HDR will pop on on the TV, while connected through AVR? if yes, what settings on which device do I have to change to get it all working or can someone confirm that my receiver needs an upgrade?

If your AVR has a switchable HDMI mode, then set it to ‘high’ or HDMI mode 2 or whatever will handle 4k at 60Hz. Likewise on the TV.

I don’t understand why that clip is playing at 1080p when vero is connected direct to your TV. Please post debug logs so we can check your settings.

To get a better understanding of the problem you are experiencing we need more information from you. The best way to get this information is for you to upload logs that demonstrate your problem. You can learn more about how to submit a useful support request here.

Depending on the used skin you have to set the settings-level to standard or higher, in summary:

enable debug logging at settings->system->logging
reboot the OSMC device
reproduce the issue
upload the log set either using the Log Uploader method within the My OSMC menu in the GUI or the ssh method invoking command grab-logs -A
publish the provided URL from the log set upload, here

Thanks for your understanding. We hope that we can help you get up and running again shortly.

log files may contain too much info, still not that familiar with log-file editing.

grahamh · 28 January 2019 20:37

This says your AVR does not support HDMI2.0 bitrates or HDR. Since Vero knows it can’t display 4k@60Hz, it falls back to 1080p@60Hz.

This also says the TV can’t support HDMI2.0 bitrates but does do HDR. It can only support 4k@60Hz with 8-bit content. Again, Vero is falling back to 1080p@60Hz because HDR is 10-bit. That should be fixable with a setting on your TV.

So unless there’s a setting on the Yamaha to enable higher bitrate HDMI (which may also enable HDR) it looks like a new AVR or an HDMI splitter is needed.

bmillham · 28 January 2019 20:52

Looking at the manual for the Yamaha, looks like it does support 4K. I didn’t dig deep into the manual but I bet it’s a setting like on my Yamaha that isn’t found in the menus, but has to be set from the front panel on the amp. They called the settings Mode 1 and Mode 2.

mtv · 28 January 2019 21:11

@grahamh

Thank you, this is in manual of 2018 Q9FN tv, UHD color is off right now.

Maybe i’ve to change the HDMI cable provided with vero4k+?

Tomorrow i’ll try test of cat again when changed that mode to UHD color on, set on HDMI3 on TV when vero is connected direct.

@bmillham

The A820 does support 4K, but i don’t have that mode1/2 option in advanced options.

bmillham · 28 January 2019 21:16

Yea, I just downloaded the manual and found that. There is an option MON.CHK that looks interesting.

mtv · 28 January 2019 21:23

Yes,i’ll chech mon.chk as well, did it with h96pro+ but that didn’t work out, so i’ll check again.

This will “read” TV.

root@osmc:/# cat /sys/class/amhdmitx/amhdmitx0/edid

What do I have to take to read the AVR?

bmillham · 28 January 2019 21:25

That is giving the EDID of whatever is connected to the HDMI cable. So if the amp is connected then it’s giving the EDID of the amp, which if working properly is actually sending the EDID of the TV.

grahamh · 29 January 2019 10:09

With vero plugged into the AVR and the AVR plugged into the TV, the resulting EDID should be all the AVR’s audio capabilities and all the TV’s video capabilities, filtered by what the AVR can pass through.

The HDMI standard requires devices to throw away any messages they can’t understand, so if an AVR sees ‘HDR’ from vero and isn’t programmed to understand that it will not pass it on to the TV. Likewise if the TV says ‘I can do HDR’ the AVR will not tell vero that. So your AVR needs to support HDR and 4k@60Hz to get the full-fat experience.

This resulted in a perfect output hdr uhd 3840/2160p 60p

Guess conclusion is new receiver or hdmi splitter to get audio via avr and video to hdmi on TV

Strange is add vendor2 and clock2 while direct on tv and with uhd color on.

grahamh · 29 January 2019 17:44

Yes.

Not strange. It just means the Yamaha does not support clock2. You can tell that from the specs in the manual, which don’t list 4k@50/60Hz.

bmillham · 29 January 2019 17:54

You could connect directly to the TV and then HDMI ARC back to the Yamaha.

mtv · 29 January 2019 18:01

@bmillham that could be, but then all audio will be muxed back to dolby digital as tv has no dts anymore, so passthrough arc will loose all audio sources.

I’ve tried that already, but dtshd-ma for example is seen as 2ch pcm and will be resolved als prologic on my receiver.

In the end, receiver is allmost 7 years old, must say that with vero4k and h96pro+coreelec i finaly could enjoy all other audio formats being recognized as my former popcornhour a100 only supported dts and dd.

So what started with a new 4k tv, ends with a new 4k streamer and possible new avr.

Still have to decide then what type/brand of avr will fit best, at least has to support 4K + HDR passthrough

@bmillham and @grahamh

Thank you for helping me out here.

bmillham · 29 January 2019 18:06

You might look for a couple year old used unit. I got a Yamaha RX-A660 with 4 Definitive speakers and a sub for $350. The equipment new would have been $1000+.
