HD Audio Passthrough
Dolby Digital (also known as Dolby AC-3)  No issues on either Kodi/VLC
Dolby Digital Plus (also known as Enhanced AC-3)  No issues on either Kodi/VLC
Dolby TrueHD  No issues on VLC...Kodi on the other hand could only passthrough core Dolby audio.
DTS-HD MA  No issues on VLC...Kodi on the other hand could only passthrough core DTS audio.
Dolby ATMOS  **Core Dolby is processed and passed on.
DTS:X  **Core DTS is processed and passed on.

Same here.. Usually it'd be the other way around and I wouldn't even need to try any other Media Player. Toggled this and that.. Didn't seem to help. Any thoughts? Onkyo AVR here.

this box able to output Dolby Vision without any issue? Not downgrading to HDR10

As a pure media streamer, the GT-King Pro does as well, if not better, than most competitions. I played many video clips of different formats in Kodi, the GT-King Pro never struggled with anything I threw at it. The GT-King Pro supports Dolby Vision, Advanced HDR10, HDR10+, HLG, and PRIME HDR, with the right videos and a nice TV, it is capable of delivering satisfying video playback experiences.

Unfortunately, I don't have access to one. Will be sure to do so if one pops up..

Not astro On the go

it is asstro AOD and cinema movie in evpad which is illegal la.

How much for the box?

Sorry.. Ask around even. Me won't discuss such illegal stuff.. Not at least ever since the govt came out publicly and charging folks. So, you do you yeah.. 
From the same xda page.. He states "No Netflix or Amazon Prime Video in HD." Which, personally I'm not surprised.. At least from an official standpoint. Beelink isn't advertising it as Netflix and or Prime HDR capable either. So I'm unsure as to the part where Amazon Prime HDR is confirmed supported. Personally I prefer to either report what I can or have tested myself and or gotten direct confirm from the tech guys at Beelink. We've got reputations at stake.

BDMV and 3D ISO etc is supported. Kodi v18 can handle those. Also..Oh, you were referring to the app "MX Player Pro" and not the box. I thought you meant the MX/MXQ Pro box.. Hence my response. No worries, I'll test that too soon.. As for auto framerate switching? There isn't a toggle to turn such on or off. But I've tested different video types and watched for its tell signs and I can say.. There are none. At least via Kodi and using Kodi's own framerate switching tech. I set it to kick in at the beginning of content being played and exit once it's stopped. Smooth playback... AFRD also works. So AFS isn't an issue on this or most AMLogic devices.

As long as a device isn't Netflix certified.. For starters, Netflix will only certify if the device is running stock ATV OS and not regular Android OS. The upcoming Minix Neo U22-XJ will be running regular Android 9.0 OS. So like the GT-King Pro, I wouldn't bank on it being capable of consistently outputting anything more than 540p res and stereo. Minix too..So forget about Netflix DV + Atmos... Again, I stress.. If one owns a Dolby Vision capable TV and audio equipment capable or ATMOS and or DTS:X levels? You are better of using the bundled TV app itself. Don't make it a criteria on an external box. Else, it's the Nvidia Shield and nothing else.

The Minix Neo T5 on the other hand would be running Android TV 9.0 with Google certification. It's unclear if it'll be a Netflix certified device at this point. I doubt it though.

I'll try my best to run as many tests as possible.. Offering clarity.. Oh yeah, speaking of Blu-ray menu support. That is a software/app dependent issue. Not something simply baked into the firmware. Beelink doesn't have a dedicated video player on the same level as say Himedia's. But as with almost all capable devices. You can install the paid app.. VidON XBMC. Should work.

Haha.. Yeah we do... Imagine my surprise that you too were discussing about Netflix Dv, etc.. haha..How about we agree that the discussion was done for the benefit of those who are still unaware of these type things. So I tried MX Player pro and it's worse.. Equipment wasn't detecting any HD audio signals. not even for basic DD5.1.. Tweaked settings here there.. HW+ to HW to SW decoding etc.. No progress. So i ditched it.. Kodi and VLC then. The following are images showing YouTube @ 4K res using the remote friendly ATV app.. Also, AFS actively working with AFRD. Main review post updated too..

BDMV ISO Selection Menu

Choosing the "Show Bluray Menu" option does nothing. File begins playback instead.

AFS via AFRD Not that I felt it was needed in the first place. Beelink made it easier to install by including it in the FW bundled "App Store".

**TV

You are welcome... I'm almost certain that DV & DA aren't as yet supported on this Pro device. Also suggested by Beelink. I just can't categorically make such a bold statement. But yeah, if those 2 are major immediate concerns? Then you might want to hold off or go for the KING... Else performance-wise, this Pro is quite the beast. I still stand by my words.. It's the second best out there. Now if only they can switch to making non-rooted devices or officially providing a no-root option. Then can recommend it highly for Asterruk app users too, as the beta works quite well on it.

Hey.. I can now confirm now that the GT-King Pro does not support Dolby Vision, Dolby ATMOS, & DTS:X. Not natively and not via hdmi pass-thru tech. The issue is being worked on and once success, will be released along with a software update. Though it is expected to ship as default with the GS-King X. So I'll advise some patience either for the King Pro of the upcoming X version. In comparison, the MINIX Neo U22-XJ does have confirmed support for Dolby Vision and Audio right out of the box. One of the few AMLogic equipped boxes to support DV on regular Android (Android 9) OS. IIRC, the Amazon Cube is another DV capable device. Minix pays licensing fees to Dolby for this support. Although afaik, they aren't coming out to state officially that ATMOS is supported.  .. As for DTS:X? That's unsupported.

One thing I do have to point out is that DV on the Minix Neo U22-XJ is being reported as a half-baked experience. Something I'm not familiar with where Minix devices are concerned. Minix are known to only release a new device with (at minimum) a stable firmware that does as they claim. They don't over-claim capabilities on their devices. So finding out about this and that they are being tight-lipped about it is unusual..IMO. Word online though is that they are aware of the issue and AMLogic has been alerted to the color issues/performance. Amlogic should by now have released another SDK version. From which Minix devs will get to work incorporating in to the next firmware update. If all goes well? there should be a firmware update soon and the DV issues should be resolved too.

Now if all these bores you and or is too much work waiting, hacking la, etc? TBH, your safest choice would be to get the Nvidia Shield instead. Confirmed all 3 capable..Personally? I'd wait.. but then I love to tinker and don't mind getting my hands dirty.. 

dolby vision and atmos support, ease of use ,  speed, streaming BD rips from ext HDD

hmm good point .. so is wait our for a tv box which can truly support , get a nvidia shield or get a UHD bluray player or using a pc
was keen on the minix u22

HDR10+, also known as HDR10 Plus, was announced on April 20, 2017, by Samsung and Amazon Video
...
Dolby Vision is an HDR format from Dolby Laboratories that can be optionally supported by Ultra HD Blu-ray discs and streaming video services.[62][63] Dolby Vision is a proprietary format and Dolby SVP of Business Giles Baker has stated that the royalty cost for Dolby Vision is less than $3 per TV.[64][65][66] Dolby Vision includes the Perceptual Quantizer (SMPTE ST 2084) electro-optical transfer function, up to 8K resolution, and a wide-gamut color space (ITU-R Rec. BT.2020 or ICTCP). Some Dolby Vision profiles allow for 12-bit color depth and 10,000 cd/m2 maximum brightness [67]

K UHD Bluray discs use Dolby Vision Profile 7 (dual layer).
There are two type of Dolby Vision Profile 7.
1. DV Profile 7 with MEL (Minimal Enhancement Layer)
2. DV Profile 7 with FEL (Full Enhancement Layer)
MEL contains dynamic metadata for HDR. And FEL contains dynamic metadata + data from the original HDR master for full 12-bit color.
Paramount, Universal and Lionsgate are known to exclusively use FEL. (only exception from Lionsgate was their recent Robin Hood release. This used MEL).
Warner and Disney are known to use MEL. (The only exception was 2001 A Space Odyssey from Warner and Black Panther from Disney. These two used FEL).

so DV is onlu 1080p and being upscale to 2160p?

actually in dolby vision certified products, they will read the DV as a metadata stream, the 1080p one is the stream only if not mistaken the DV chip will use that stream, the normal will still using 4k. roughly something like this la.. so even now mkv player also cannot able to read 2 stream at the same time. maybe the mkv need to update to incorporate DV into 4k stream or how. HDR10+ already got but dunno y LG don wan support  they say their dynamic tone mapping is actually same like hdr10+.

i see.. so for beelink gt-king pro or non pro, both also can play 4k hdr10 mkv remux with no issue right? Now i using plex to my lg c9, but the lg c9 app cannot decode loseless hdma or truehd. Does beelink gt-king got plex? or what is the better way? previously i normally copy to HDD then plug tvbox only can play, but now i find this too fussy after using Plex which can auto catalog things i downloaded.

ur requirement the tvbox will be very very expensive 

so among the current box am6, am6pro, minix t5, minix u22-xj, himedia s500, shieldtv pro.  which would be the best ??

I saw this A95X MAX Plus not sure is as good or not though

if price around RM 1000 above i think i would rather get a mini pc which would provide more flexibility thand a tv box

in the end i settle for a cheaper TX3 box with AMLOGIC s905x3 SOC which cost me RM 175.  so far it could play DV, DA, HDR rips , but like u say depends on the rips . funny thing the rip says atmos, but sometimes it jst show DOLBY AUDIO , but the witcher rip could play DA and DV . Also im guessing it depends the software player too

how bout the nvidia shield pro ??  it is able to pass thru advance audio meta?
