Lg nano79 smart 4k lg + um7340

Hi again.

Is very enoingh because a few month ago before the lastes updates it was working very well, and now things that i watched before, doesn’t work now :frowning:

In 2 days i will have finally better internet speed.
1000mb download and 100 up, now i have 100/5 :frowning:
Hope this will solve the problem.

But the ither thing i don’t understand is that on android i can watch a TV Show and in the Acer Noteboot i can’t :frowning:

Your TV does not support TrueHD and DTS audio. Unsupported audio with enabled subtitles results in video transcoding and burning in subtitles (CPU intensive task).

Ok, what i was thinking, but if that the case, why one movie i can see with sound, and the other don’t??

The first picture that only works with AC3 5.1 is Wonder Woman,
The other picture is LOTR I think and the TRUEHD 7.1 Works… :frowning:

No, it does not work. Your TV doesn’t support TrueHD so stop using those audio tracks. If you have TrueHD and DTS capable receiver or soundbar buy a Nvidia Shield. Otherwise its waste of resources

I have an Onkyo reciber on the 55" TV.
I don’t know if it’s helps…
And i see what i have from the Internet dude :sweat_smile:

what model?

Onkyo HT-S3800-B 5.1 + Receiver & Suboofer.

OK, a little update, seens last thusday i have the new inter speed, 1000/100, and now works perfect the plex outside if my network, i use on the notebook with the windows plex, so the PGS works.
The only this is still with the LOTR 4K, i don’t know if is because of the internet or the notbook, maeby you can tell me

Thanks very much for your helpful explanation. I have the same issue with my LG CX (no DTS support) and 4K HDR movies (with DTS soundtrack) when the subtitles is turned on. Do you know whether an apple tv or shield pro will solve this issue? Will the plex client app on these two platform only transcode the audio to supported format (and not the video part) while the srt subtitles are turned on? Thanks!

This is how the Plex LG app behaves with subtitles:

  1. Enabling image based subtitles, PGS or VOBSUB, results in a video transcode.
  2. If audio is transcoding, enabling any subtitle results in a video transcode.
  3. If audio is direct playing, text subtitles, SRT & VTT, direct play.
  4. For ASS/SSA subtitles:
    1. If Burn Subtitles = Automatic in the Plex LG app, enabling ASS/SSA subtitles results in a video transcode.
    2. If Burn Subtitles = Only Image Formats, ASS/SSA subtitles, direct play, but formatting information (color, location, etc) may be lost.

Short Answer:
Apple TV: I do not know.
Shield: Yes.

Note: Direct playing SRT or PGS/VOBSUB subtitles while the audio is transcoding is part of the Plex Android TV client. It is not specific to the Shield. So, you do not necessarily need a Shield.

For example, an Amazon Fire Stick 4K will also direct play subtitles when the audio is transcoding. All the audio will be converted to either Dolby Digital or Dolby Digital Plus, so no dts or TrueHD (and in some instance you’ll receive 2.0 audio even if the source is 5.1). However, depending on your listening environment that may not matter to you.

Long Answer:

I do not know how the AppleTV handles subtitles (I do not have an AppleTV with which to test).

Due to Apple restrictions, the AppleTV cannot passthrough TrueHD audio. If I remember correctly, Plex Media Server transcodes TrueHD to FLAC. The AppleTV then passes it to attached audio equipment as multi-channel PCM. The TrueHD → FLAC → PCM action was reported on a thread several months ago. FLAC & PCM are both lossless, so there should be no audio degradation due to the conversion. However, any Atmos data is lost in the conversion process.

The AppleTV passes dts audio as multi-channel PCM.

A Shield will direct play subtitles even if the audio and/or video is transcoding. This was added in v8.0 of the Plex Android TV client.

So basically, you could play a 4K HDR video, have the dts audio transcoding, enable PGS or SRT subtitles, and the video won’t transcode.

A Shield will passthrough TrueHD (including Atmos) and dts/-HD/:X audio if the attached equipment supports those formats. If they are not supported, then the audio will be transcoded to a supported format.

Note that the LG CX will not passthrough dts audio formats from equipment attached to one of the TV’s HDMI inputs. When LG removed dts audio support from their TVs they also blocked dts passthrough from attached devices.

Also, passing TrueHD and dts-HD through the TV requires that both the TV and the attached audio equipment support HDMI-eARC. HDMI-ARC does not have the bandwidth to pass TrueHD or dts-HD. HDMI-ARC is limited to Dolby Digital, Dolby Digital Plus, & dts at 5.1 channels or less. PCM 2.0 is also supported.

If possible, it is best to connect the Shield (or any streaming device) directly to the audio equipment. This lets the most audio formats direct play.

Example: Streaming device <–HDMI–> Receiver/Soundbar<–HDMI–> LG CX

It is not always possible, due to a lack of HDMI inputs on the audio equipment, or for other reasons. You can still connect the streaming device directly to the LG, but dts audio will be transcoded due to the limitations of the TV.

Example: Streaming device <–HDMI–> LG CX <–HDMI-eARC → Audio Equipment

I’ve kind of rambled a bit. Hopefully I answered your question. If I have not, or worse, left you horribly confused, let me know and I’ll try to straighten things out.

VERY Helpful indeed!Is there anything better for a shield TV than firestick 4K in terms of streaming 4K movies locally only? given it’s much higher price tag lol

The “new” player is dealing with DTS fine for me – haven’t seen much transcoding on my server when using an Apple TV 4K (if any). However that’s only true for the regular DTS – from what I remember, the Apple TV won’t play DTS HD/:X or Dolby TrueHD audio (requiring the audio to be transcoded). If you have a lot of those and the respective home theatre equipment, the Shield should give you a better experience.

I suppose the Shield is more expensive but it’s also kind of the reference platform for Android TV. From the complaints about weak FireTV sticks in the forum I think it’s safe to say the Shield will provide a better performance in general navigation / usability and supports more formats

@tom80H Thanks for the AppleTV info.

To follow up on tom80H’s comments on the Shield & FireStick…

I’ve a Shield Pro (2015 model) and a FireStick 4K. They represent different ends of the Plex client spectrum. The Shield is the premium device and has the premium price. The FireStick 4K is not as feature rich as the Shield, but works well in the right situation, and is 1/4 the price of the Shield.

The Shield is my primary Plex client. If you want to passthrough audio unmodified, then you want a Shield. It is the only client that can do so. It has a stock (or very close to it) Android TV interface - no ads, no skins, etc.

My setup: Shield <—> Denon receiver <—> LG B7 OLED

This direct plays everything I throw at it. It is rare that something transcodes.

If you go with a Shield, get the Pro model. The non-Pro “tube” model is prone to audio dropouts when playing high bit rate media such as 4K HDR Blu-ray rips (multiple reports in the forum about this). The tube model is probably OK if you stream just 1080 or lower resolutions.

The FireStick 4K also works well for me, but does not have all the capabilities of the Shield (expected given the price points). I have a few friends & family members that stream remotely from my server. They’re using TV speakers or lower end soundbars and just need good 5.1 audio. The FireStick 4K works great for this. The FireStick 4K can be set to send all audio as Dolby Digital, Dolby Digital Plus, or PCM (pick the desired format in a FireStick, not Plex app, setup menu). This works quite well from a compatibility point of view since those formats are supported by pretty much any TV, soundbar, etc you’ll find on the market. The FireStick cannot passthrough dts or TrueHD. They will be converted to the selected audio format.

The FireStick uses Amazon’s version of Android TV. You see movies, shows, etc from their streaming service on the home page. Once you’re in the Plex app things look the same as on the Shield or any other Android TV device.

If you go with a FireStick, get the FireStick 4K, not one of the other models (the Cube v2 is probably OK as well). I’ve tried some older model Firesticks and the Cube v1 and they just don’t work as well for Plex. The FireStick 4K lists for $50 USD and is frequently on sale in the $35 - $40 USD range. It isn’t worth saving $5 - $10 USD to go with one of the non-4K sticks.
