How does this work? I thought the audio from even the best TV was average at best?

 

And you can't pass Atmos to an external receiver via optical or ARC can you?

 

Or am I missing something?

correct - ARC has the same bandwidth limits as optical spdif, to get the hi-res formats or atmos you need to wait for eARC which is a hdmi 2.1 feature - and none of the current crop of TVs do hdmi 2.1 (maybe the 2019 models will support it)

I'm struggling to catch up with home theatre audio trends lately.  Atmos at home via a sound bar seems counter intuitive to me.  I thought the point of Atmos was having speakers above, behind, beside, and in front of you.  Some virtual shenanigans with time delays and angled speakers in the soundbar might give a nice virtual sound, but surely nothing like the real thing.  I do like my soundbar in terms of it's depth of sound (LG SJ5) but it's certainly not anything like having a full audio setup. Convenient though.

So, am I pretty much correct that my new TV that touts Dolby Atmos (via "virtual surround") is pretty much nonsense if you are actually interested in good sound?

 

Note: I use an external receiver for true 5.1 sound (don't have the budget for anything more than 5.1), so this is just an academic question.

I think any TV that touts any kind of sound that comes from it's own speakers rather than a sound bar or other external processing is nonsense.

...l except maybe the new Sony models where the screen itself radiates the sound. Haven’t heard them but reports here on gz say they sound exceptionally good.

I was looking at the same thing with the latest LG OLEDs. However after looking at the owner's manual it appears that it is limited to the TV speakers. Quote from the manual;

"Atmos is the ultimate sound experience which creates moving audio that flows around you using TV speakers."

I was hoping that since Netflix UHD includes Atmos on LG TVs it would be able to be fed to compatible AVR via ARC. But it seems not. It does widen the TV choices back out again (Panasonic FZ series just arriving at retailers) not trying to get an 'Atmos Enabled' set. Probably the only LG TV that might do an even half decent job of object oriented audio is the expensive wallpaper TV series with its high spec sound bar.
I will just wait to confirm that the Apple TV 4K will get Atmos with the release of TVOS12 in September. Or maybe Google will get off it's ar$e and give the Chromecast Ultra Atmos capability.
I'd really like them to separate Atmos and DTS:X from UHD Video. I have a good Atmos audio setup in the home theatre but only a full HD projector.

Are @freitasm and @sbiddle part of the marketing BS?

I don't care who says it or posts articles about it.

 

Both ATMOS and DTSX rely on multiple discrete speakers to create a sound field which then allows for discrete object placement - both horizontally and vertically.

 

Any soundbar/tv which has these speakers clustered within 1m or so of each other is at a serious disadvantage - and will NEVER be as good as discrete speakers placed around the listener. 

 

 

 

PS: I had / have the same view of HTIB systems - they are small and convenient for those who don't want to go to the hassle of a proper HT set-up - but will NEVER compete with proper HT setup. IMO they don't even compare to a decent amp + bookshelf set up.

 

PS: That said if people are happy with this approach to ATMOS - cool, awesome go for it - but man do they pay a premium price for it. eg. @ $1,700 USD.

Edit: And Era - my post wasn't addressed to you - rather the OP and the questions as to how could this approach possibly work?

I actually don’t disagree with you. It’s been long time since we have used the built-in speakers in a TV.

All I was saying was some guys on here who have a few clues have actually heard the Sony screen-sound system ears-on - and they said it was very good. That’s not really marketing BS. I’m guessing they meant very good compared to normal built-in speakers.

Don't know about TV's with Atmos but there are sound bars with Atmos.

I recall a couple of CES's ago I heard an Atmos soundbar system that was pretty good.

 

IIRC it as this unit.

 

https://www.amazon.com/Onkyo-SBT-A500-3-1-2-Dolby-System/dp/B01MUCPTP2

 

But they did have a separate sub and it was a controlled environment.

 

But really you can't beat separates all around.

The Sony does sound pretty good for TV speakers... but that's about it.

 

I was under the impression that LG's ATMOS marketing was related back to its ability to pass a signal like Dolby Digital + (that can carry multi-channel audio) to an amp or soundbar when a user plugs an HDMI source directly into a TV... whereas a lot of TV's simply follow the HDMI EDID protocol and output a stereo signal when playing an HDMI source.

 

 

 

Or -

 

LG likes to confuse things with rubbish marketing.

 

After all, you can buy Dolby ATMOS laptops...

 

 

 

 

 

For the record, I've sat down with quite a few higher end Dolby ATMOS soundbars and if you have a flat roof and square walls around you it's pretty freaking cool.

Typical... I just bought an LG C8 thinking the Panasonics would still be a couple of months.

 

The twin tuner on the FZ is a good feature.

 

Although I believe the FZ doesn't do Dolby Vision (but does do HDR10+), while the LG C8 does Dolby Vision (but not HDR10+).

 

Unfortunately you need to roll the dice on what next gen HDR format you think will stick around (it's VHS/BetaMax & Blu-Ray/HD0DVD all over again!).

LG OLED can output Dolby Atmos (DD+) over ARC (so streaming Dolby Atmos format from Netflix etc.) but not TrueHD - this requires eARC, I belive.

hmmn...

 

dolby atmos is not dolby digital plus

 

dolby atmos is an extension to dolby truehd

 

 

 

there is no device, afaik, that can do dolby atmos and not dolby truehd. it's actually the other way around.

 

atmos source to receiver that can only do truehd, output is truehd
