Different hardware combinations and beyond that different settings ... there's a slew of variables.

So here's two specific jump-off questions. In this context an "audio-sync problem" means sync values that change with different video/audio formats. (A single consistent sync offset value is not considered a "problem".)

1. Setup: ATV4K > AVR > 2016 LG OLED C6/E6 (those two models have same panel and proc). Is there anyone who has no audio-sync problems? If so which AVR are you using?

2. Setup: ATV4K > AVR > Sony OLED A9F (or A8F). Is there anyone who has no audio-sync problems? If so which AVR are you using? (Curious if the Sony OLEDs have less sync issues than the LG OLEDs?)

Thinking of moving to an Apple TV4K for streaming Netflix and Prime.

Was doing this through my 2016 LG OLED TV however that only provides (via ARC - Denon AVR6300) lossy sound codecs (and won't do ATMOS). Of course it does provide HDR and Dolby Vision.

I moved to an Xbox One S for streaming. This recently received an upgrade which now means XBOX One Dolby Vision is no longer compatible with my TV's Dolby Vision.

If I move to an AppleTV 4K will I be able to watch Netflix and Amazon Prime video with:
  • UHD 4K HDR
  • Dolby Vision
  • Dolby ATMOS
  • Other lossless audio codecs?

Or am I likely to wind up compromising in one way or another. At the moment I can get Dolby Vision using the TV but that means a lossy soundtrack. Via the Xbox I can get HDR and Dolby ATMOS.


And no, I'm not simply replacing the XBOX to get this functionality. Another device elsewhere in the house has died and I'm thinking of replacing it with the XBOX and getting an AppleTV provided the AppleTV can deliver HDR/Dolby Vision/Dolby ATMOS without issue.

Anybody know if the AppleTV can do this and if so might there be issues in my setup: AppleTV>Denon AVR6300>LG 65" OLED B6?

Cheers

No streaming service for video offers lossless audio. The ATMOS is the lossy DD+ variant. The ATV4K does offer HDR10, DV and ATMOS when available.

Whatever those things are they must not be useful to me because I find I can do whatever I need to do with my Harmony. If there are specific features that I need that aren't available on the basic Harmony screen, I just click on Devices -> ATV4k and just move to where ever.

Just checked...

There is no option listed under "more info" that allows you select a different language or select subtitles. It only list exactly what you mentioned. Maybe someone with a non iOS device will be able to verify if it's just an iOS thing.

Like I mentioned earlier, just swipe down on the track pad once a movie/show has started and you will have the options you are looking for.

Is there a way to get the ATV to force all HDR playback to reg HDR10? I.e. all DV content would also play back in HDR10?

I know I could set the "global" video output to "HDR" but I'd rather not do that. I think the SDR content generally looks better in SDR mode.

Connect to an HDR10 only TV. Otherwise unless you have something in between that doesn’t support DV you’ll have to force everything in HDR10.

I believe the DV spec only supports 24hz and 30hz (every device I've seen or read about is forced into those frame rates when playing/processing DV).

If I set the ATV global to 4K/SDR/60hz mode, turn on Match Dynamic Range but turn off Match Frame Rate - will the DV HDR content now be played in HDR10 mode?

I have a handful of UHD discs. I have compared them but the hassle of discs may have biased my perceptions. Testing Avengers Infinity War using UHD disc and Vudu 4K I could not find enough difference to make using the discs worth while.

I think your best plan is to do a comparison yourself ... If you don't have 4K discs compare a Blu Ray to HD iTunes copy

Lossless does sound better. Just maybe not significantly better.

I wouldn't call it a "huge" difference, but definitely discernible. With highly dynamic soundtracks like Saving Private Ryan and Ready Player One, the lossless audio is just more enveloping and "hitting." With dramas and comedies, it's not as noticeable, other than usually having to turn the volume up a few Dbs.

The ATV4K supports Dolby Vision at 60hz or lower. Some display devices and AVR's (depending on when they were manufactured, and/or the strength of the onboard processor), will only playback Dolby Vision at 30hz max. The typical playback frame rate for a movie - (disc or streaming) - will be 24hz, and streaming TV shows will generally be 30hz; so if your display device is Dolby Vision capable, you shouldn't have any issues playing back almost all DV content, with only a couple of titles out there being exceptions.

However, if you want to force full time HDR10 content playback, you need to set the ATV4K Home Screen to HDR10.
EDIT: And turn OFF range matching.

Remind me again: why you are wanting to disable Dolby Vision?

I just tried these settings using Altered Carbon on Netflix as an example. It works. I know there are some folks who have been looking for a way to output HDR10 only. Yours is the first option that seems to work, at least on my setup. I suppose there may be some differences in results depending on the hardware in one's system.

Those who may prefer HDR10 will get the occasional flabbergasted response from some AVS posters, though. Just be prepared.

DolbyVision on my previous TV didn't look the best, so I opted for HDR10 whenever I could. My current Sony 950G, however, handles DolbyVision much better, so I use it most of the time.

The Dolby DoVi specification supports all common frame rates. The general idea is you have X bandwidth (the examples range from 20-130 Mbps) which supports various combinations of frame rate and resolution. The ATV4K supports a sub-set of the combinations including 50 and 60 fps.

I wouldn't depend on this being a reliable or long-term solution. The more robust approach (as implied earlier) is to get an E-DID manager that removes DoVi and put it (immediately) downstream of the ATV.

Very similar experience on my system (Bluray/ATV, 5.1). I also notice the difference maybe a bit more in the surround channels.

Thanks to all for the (more informed) responses.

... Remind me again: why you are wanting to disable Dolby Vision?
Dolby Vision keeps showing up as a variable/problem as I'm sorting out the ATV sync issue. In an ideal world I'd like to keep it.

Kind of leads me to my next question ...

I have a 4K display (LG E6) and the ATV4K but an older (HDMI 1.4) Denon AVR. I'm hoping to wait to upgrade my AVR until HDMI 2.1 units come out. While I'm willing to wait for Atmos, the current issue is that the AVR won't accept/process a 4K or HDR video signal. My UHD BluRay player has a second HDMI out so getting 4K/HDR picture with my current setup isn't a problem (separate HDMI outs to the TV and AVR).

For the ATV4K I'm looking for an HDMI splitter that can output two different signals (4K/HDR for the TV and 1080 for the AVR) at the same time. The one's I've tried so far don't work - they will only send the same signal on both outs (if the switcher senses a 1080 device both signals are scaled down, or, if both signals are 4K/HDR the AVR chokes).

Is anyone using, or know of, a specific HDMI device that can do this?

Also curious which test clips you use and what method you use to play them on the ATV.



Thanks!

The app is called Synchronism. They provide links to download some test clips. If i recall i used some similar clips i had already downloaded from a hw vendor’s avsync site. These played back better on my Panasonic UB420 4K blu-ray and Apple TV. I used infuse to play on the appletv 4K.

The app is awesome, it uses the mic and camera to measure the plip sound and white flash frame offset. I think it worked on an ipad as well as my iphone and was more radable on the bigger screen.

Regards, Rob.

[HDFury] makes a various products specifically for this purpose. Video processors have a [dedicated AVS section].

I might type 2K for 1080p.
