@shawnc22 are you able to elaborate at all, or provide a link to more information, about the compatibility of the LG OLED X-Generation?

I currently have a C8, but am looking at getting a CX. But I'll will think twice if it can't play these.

Thanks

Hi, I wouldn’t NOT get a CX just because it may not play dual layer mp4 files.
It has a much better peak processing in HDR content compared to the C8.

With the new Firmware CX9 plays DV DL mp4. Tested with James Ryan.
I think it's a little dark.

edit:
it is the same as when I create a DV SL from Private Ryan -> it plays only BL+RPU, not the EL. Picture is falsified :x
I think that the TV is not able to decode 2x HEVC at the same time.


So the purchase of the UBK90 was not in vain :D

Of course it can physically play dual hevc streams. Are you sure you have the same picture setting for Dolby vision over media player as you do for HDMI input?

100% Sure.

In (rare) films with FEL, such as Private Ryan, omitting the EL leads to errors. In this case, the brightness pumps into bright scenes and dark scenes are far too dark. Otherwise I might not have noticed.

where do you get the information from that it can play 2x hevc?

But wouldn't leaving out the EL just make it play exactly as it would on any TV/player that doesn't support DV? So does that mean in rare cases like Private Ryan even the original UHD Blu-Ray will only play properly on DV capable equipment? That sort of thing shouldn't happen should it?

The HDR10 plays without Errors.

If you play the EL alone (Ryan) on MPC you see the brightness flashing.

Don't know how the RPU can make the brightness pumping playing the DV without EL.

Buy private Ryan and test yourself! If U don't believe me.

CX9? Do you mean the LG OLED CX or the LG OLED C9?

Can the UBK90 install apps like Emby or Plex to play DV mp4s over a network?

Wouldn't you be able to test if the CX can decode 2x HEVC at the same time by muxing a DV mp4 with the main HEVC from one film and the EL from a different film? I did this ages ago just to see what would happen, and the colours were all crazy when played on my C8. If you did this and it played with the crazy colours on both the UBK90 and the CX it would indicate the CX is decoding the EL. If it played crazy colours on the UBK90, but looked normal on the CX it would indicate the the CX is only playing the main stream.

Does that make sense, or is my thinking off?

It's not that I don't believe you, and I don't have a CX or UBK90 to test any way. I was just wondering if something else could be causing it other than the TV not decoding the EL.

I haven't looked at this stuff in a while, so I don't know what the RPU is or does - I'd never heard of it before reading your post. Does every DV Blu-Ray have an RPU?

It's mostly just reports from people on this forum who have said the CX hasnt been able to play DTDL mp4s, but that supposedly changed with the latest firmware. You'd have to ask people here who have that TV for confirmation.

Does UBK90 also support DTDL and lossless audio in m2ts?

Any proof on this? Because measurements show the CX have lower peak brightness in hdr compared to previous oled generations.

OLED77CX9LA

UBK90 -> i think not, only USB.

If you give me such a mp4 I´ll try!

I made 3 version of Ryan: DV DL, DV SL & HDR10: https://drive.google.com/file/d/1NK71Ck ... sp=sharing
you can try yourself

UBK90: DV DL correct, DV SL pumps
CX9LA: DV SL + DL much to dark + pumps.

m2ts/ts will be played in HDR10 + lossless audio.
DT = DV ?

DV without RPU is HDR10 :roll:

DT - Dual track. Profile 7 from UHD disks have one track with base layer and another track with enhanced layer. I actually thought of asking whether it supports m2ts playback from USB. Sony's X700 and 800m2 supports them.
