In Android settings go to Settings > Display & Sound > Dynamic range & Color format and set Match Content Dynamic Range to Match Content. For Dolby Vision, enable Source Device - LED in the Dolby Vision settings, and ensure the Primary Dynamic Range is set to “Use same dynamic range as Content > Always match content format”. This setting will automatically play SDR content in SDR, HDR in HDR, and Dolby Vision in Dolby Vision, rather than converting everything to a single format.

Recommended video settings

  • Match Content Dynamic Range: Set this to Match Content. This allows the device to automatically switch between SDR, HDR, and Dolby Vision formats based on the source.

  • Dolby Vision Processing: Enable Source Device - LED so that the box applies Dolby Vision based on the content source.

  • Primary Dynamic Range: Set this to Use same dynamic range as Content > Always match content format.

  • HDR Settings: Ensure HDR Settings is enabled for the feature to work.

  • Dolby Vision Mode: You can set this to Low Latency for a better experience.

I’ve noticed if the Android is set so the device will boot to CoreElec with correct screen settings, colors.

Thanks for the quick response. Just to confirm the connection, can you please clarify which option to go with?

  1. Homatics Box —> HDMI eARC —> LG G4 TV —> HDMI —> Samsung HW-Q995D Soundbar
  2. Homatics Box —> HDMI —> LG G4 TV —> HDMI eARC —> Samsung HW-Q995D Soundbar

And the software config should work as is. No changes, right?

6120

No, you will need to check your TVs guide how to proper connect all devices.
eARC means audio RETURN channel, not forward.

I use the latest NG nightly I guess, I update whenever the update popup appears.

Thanks for the tip about jellyfin app, I might try it sometime. (Though I guess it will have LG limitations with DTS passthrough and maybe something else)

6123

You connect your soundbar to the eARC port and all other devices to any of the HDMI ports still available. Your G4 can passthrough all HD audio codecs your streamer supports, just choose the correct HDMI port settings on your LG and you are good to go.

I also have a G4 since recently, specifically selected over a G5 because of it’s full HD audio passthrough support, I don’t need that brighter picture the G5 can deliver.

Why straight to the LG and not the Marantz Cinema receiver that I have? No QMS support when using Marantz for passthrough (if a streamer would support that option), and resolution/refreshrate + HDR switching goes much faster when straight to TV.

6124

Yes, Box → to any HDMI TV port except eARC. TV → eArc HDMI port to Soundbar.

I have quite some experience with the Jellyfin WebOS app.

The video limitations are that it will always fallback to HDR when it plays DoVi 7.6 files.
The audio limitations are that it will not passthrough TrueHD or DTS codecs to your soundbar. These codecs are always transcoded to AAC.

It plays DoVi 5 and 8 mp4 DoVi files flawlessly. In the recent updates, it started playing mkv files quite nicely.

Hi is moving data to emmc possible on android 14? I am searching for the guide but struggling, thanks.

Good question, i was thinking about using a ssd connected via usb instead of usb pendrive

Even if is usb 3.0 and have good writing / reading performance…200-250 mb/s, coreelec menu are sluggish compared to kodi android

6132

There are also pendrives with a very decent read speed, like the Samsung FIT series. Using a SSD as CE boot image didn’t bring me anything much compared to the Samsung, the USB3 port is what is holding it back on pure speed.

Just to confirm, using a faster USB drive to run CE on only contributes to a slicker UI but not in anyway to Dovi 7.6 FEL playback, right?

This is my test Samsung Fit (test find online) vs my Sandisk pendrive

I can’t test with higher files cause coreelec partition, btw the big difference is in random little files

6135

Could you provide a 7.6 fel files so i can test back ? i have many udh rip (50/60 gb) and i don’t see any stutter or frames skip (with my eyes, i don’t look in log)

If you tell me which of these files is giving you problems, I’ll try it out of curiosity.
