I am begging for 3D LG support! Please!

I have an LG OLED55C6P 55" 3D TV (passive 3D technology), a Roku 4, and a gigantic collection of digital (mp4) 3D movies which I cannot enjoy unless I watch them directly from my flash drive. Part of why I bought the Plex Pass was because I read that Plex supports the 3D format, so I definitely feel like I’ve been a victim of bait and switch.

The TV does present me 3D mode as an option, but the signal from the Plex server is formatted incorrectly, so the resulting aspect ratio is 32:9. There is surely some small rendering detail in each frame that the TV is looking for which is being suppressed by the Plex software, so the TV just displays both left/right images side by side instead of interlacing them every other frame as 3D should be. I have put H-SBS at the end of every filename as instructed by Plex. I have tried all possible aspect ratios (zooming, no zooming, standard, 16:9, etc.) on the TV. The problem persists. It is pretty obvious that the TV is not at fault since any given file plays just fine from a flash drive plugged directly into the TV, while the exact same file plays incorrectly when Plex is transmitting it to the TV.

For additional information (and corroboration from other users!), please see:

Plex, please realize how important this is to the 3D community. It also seems to me that this isn’t really a feature request - it’s really a bug that prevents Plex from living up to what the Plex website claims it does, and with that, it seems to me this should be a really high priority. You shouldn’t be adding additional bells and whistles to Plex until the bells and whistles you have already advertised are fixed.

Taken directly from the official Plex website:

“Is 3D playback supported?”
“Yes. However, note that there is nothing special that the Plex app can do to instruct the television that a specific video is 3D. You will need to enable the appropriate 3D viewing mode on the television yourself.”

I’ve enabled the appropriate 3D viewing mode on my television myself, I’ve put H-SBS into the filename, and still it doesn’t work for anyone with my model.

I spent good money on a lifetime Plex Pass largely for this feature, so the failure to support it has been extremely disappointing.

I also have a passive 3D LG TV and it works fine for me. Just as the website state “You will need to enable the appropriate 3D viewing mode on the television yourself.” They mean you will need to do that manually using the remote control. I keep all my 3D movies in a separate Library. When I start playing one its in 32:9 format. I press the 3D button on my remote (Harmony Universal) and it initializes the SBS 3D setting in the TV. The volume, scanning, scene selection is all messed up when displaying but the 3d video adjusts to overlaid 16:9 and works like a champ.

i can second McFadden here. most of my movies are HSBS and when you play them they play like double movies until you hit the 3D button on your LG remote. Works great!

Same here.
My LG is fine, but you do have to manually select 3D and select the 3D format.

I would also like this. That said if you have an Open PHT compatible media player (mac, windows etc), it is supported with that third party platform and works well

McFadden, Buckeye and jjr, it sounds to me like you don’t own the exact same LG model I do. My TV is a OLED55C6P. It is curved and does not include a sound bar. Is that your TV too? Please see the thread I linked to for corroboration of other users (and their explanation of what is happening).

I already do what you describe. I do it all the time when watching 3D movies from my flash drive - I hit the 3D button and choose the side-by-side layout, and it works perfectly. My aspect ratio is set to 16x9. This same process / settings do not work when watching via Roku’s Plex app.

By the way, I contacted LG, and they verified that this is a problem with Plex.

On the bottom-left of the remote you should see a button with the label 3D. Push that and follow the on screen instructions.
Works fine with my LG TV.
Good luck!
