Passive 3D and Active 3D screen discussion.

[Gravy]

I thought I'd best start a new thread rather than continue to derail Freezy's thread in response to @mandermannen questions regarding 3D screens.

Really Thanks for all the tips! I just found this tv https://www.lg.com/ca_en/tv-soundbars/oled/oled42c2pua/?srsltid=AfmBOoq4CE-j0skmlWTR_dbCrYhPYcKsSsKxVNKqYnMz0_ZPVeMKpqO6

 

It says it has 3d? If this really is then I have to find one. I try to send you a pm but it didn't work,I also do not want to hack this thread with my things

 

The LG C2 is a great screen used by quite a few VP cabinet owners but unfortunately not 3D (I couldn't even see it mentioned on that page you listed, perhaps its hidden in the meta description of the page or something). LG did release a few passive 3D OLED 4K screens up until around 2016 I think but they were not available in the smaller 42-43 size. I think the smallest 3D OLED was a 55".  They did release a 4K passive 3D LED TV at 49" size which is about the largest you would probably want for a pinball cabinet. 55" is too big really.

There is a project that a guy is working on that makes the older LG 42" 4K OLED C1 screen work in active 3D with some additional hardware. It doesn't work well with newer OLED models such as C2 though due to needing "black frame insertion" (BFI) function which the newer models dont have. As its an Active 3D technology I'm not sure how well it works in rotated portrait mode as there are sometimes issues with polarised lenses blacking out screens when rotated (there are fixes for that though). The project is at https://github.com/open3doled/open-3d-oled

The project owner mentions that once we get 240hz OLED screens, he may no longer need the BFI function to make it work in 3D.

This is also very interesting stuff! Is says that gaming is not well supported. That it needs additional software. But how does that work with vpx, some sort of reshade? And the link of his email is not working, do you maybe have its email? I hope that 3d will come back on the newest tv's. I believe theres a market for it, with 3d models of other games. I will email LG for it 😀I just ordered a LG 42LA7408 and will get it Sunday, then testing the next few weeks

If the email link on his github front page isnt working I've noticed that people are opening a new issue and stating their intention to get more info and leaving their email address to contact them. The dev seems to be responding still in the last week or so.

I don't know a lot about that project in regards to gaming, I assume it would use reshade depth3d or possibly support games that have native 3D support such as VPX (GL) via side by side or top/bottom 3D etc.

And then i found this monitor;

 

https://www.samsung.com/nl/monitors/gaming/odyssey-3d-g90xf-27-inch-165hz-uhd-ls27fg900xuxen/?srsltid=AfmBOooXIHGKsvBZEjlNm3Vb_T5yL0FdJpO4BQT6qejP3RiuoQXtrxBq

 

But i think its more of a head tracking experience. I tried that but that was not a 3d experience. I will search for the 4k 3d monitors you mentioned but so far no hits.

[mandermannen]

https://tridimensional.info/product/tridimensional-passive-4k-3dtv-65/?srsltid=AfmBOoq4ip5dqNiUGDOaUB1DSh647vH-WdAMx0kLTLDLtoTGHCPHHLzb

 

Do you think this is fake?

[mandermannen]

https://eizo-or.com/products/medical-monitors/endoscopic-monitors/ex4342-3d/

 

This is not fake. I ask for the price. Hope they sell to individuals

[Gravy]

@mandermannen I've seen that Tridimensional page before... it's a bit misleading as the 42" version is actually only 1080p when I investigated further in the "Additional Information" tab.

Regarding the Eizo ... any time you see the word "medical" in any item, expect to pay through the nose. Even the non 3D version of their 43" 4K is about US$10000 https://www.monitors.com/en-au/products/eizo-ex4342 . I can't find an RRP on the 3D version. It may or may not work in portrait orientation, the 3D screen appears to possibly be using Active 3D glasses but I'm only going by the images of the people wearing them, cant see the full details in the description which is weird. If a screen blacks out when rotated when wearing active 3D glasses it is possible to fix this issue somewhat by applying circular polarised lenses over the top of the existing glasses (for instance from a pair or RealD Polarised cinema 3D glasses), this will dim the image further and may cause some colour distortion/rainbow effects but can be a viable option.

Regarding the glasses free 3D Samsung Odyssey 3d g90xf 27" 165hz uhd. The problem with any autostereoscopic screens is they are unlikely to work in portrait mode needed for cabinet use as they use a lenticular screen which only works in one orientation. You would need an autostereoscopic screen that is designed for a shopping centre display in vertical mode for instance. I think that screen is proper stereo 3D in landscape mode and additionally it uses headtracking to adjust the perspective similar to BAM on Future Pinball and VPX. When paired with true stereo 3D, headtracking would be very realistic.

I think the best bet for the the Virtual Pinball community in terms of 3D screens would be to somehow convince Vestel in Turkey to restart production of their  ves430qnel‑3d‑u01 43" 4K passive 3D panels. They were only 60hz but perhaps could be made 120hz with some additional hardware. This would be a lot easier/cheaper than getting a company to produce something similar from scratch.

Oke i will give it a try at Vesel, you never  know... something like this:

 

Dear Sir/Madam, I am speaking on behalf of the virtual pinball community. We are a vibrant community with a large number of virtual pinball cabinet users worldwide. Through software (VPX) and hardware, it is possible to play on a real pinball cabinet, but via screens. Because a 3D model is used in VPX, the ultimate viewing experience is via a 4K 3D passive screen. Unfortunately, production of these 3D screens has been discontinued worldwide. With its ves430qnel‑3d‑u01 43" 4K passive 3D screen, Vesel was the last screen that perfectly suited our cabinet users. We are now wondering if you are interested in restarting production of this type of screen? I assure you there is a lot of interest in this screen from our community. However, I can also imagine that there is a lot of demand from other markets, such as games that make use of 3D models. And VR is fantastic, of course, but you miss the connection with the environment. And it is precisely the contrast between the environment and a 3D experience on a real pinball cabinet that makes watching 3D with passive 3d glasses amazing. Thank you in advance for your reply.

[mandermannen]

Oke so i got my 3d tv from lg. First reaction is wow! This is how you should be playing vpinball. Its looks like you playing a real cabinet! But of course then you compare it with my 4k screen. You see the black lines and its not that sharp . But, after some thinking i choose the 3d tv. It really outcast the 4k. You see things that you dont see on 4k, even if 4k is sharper. I just place the less sharper image as retro image in my head, and then its perfect!

[mandermannen]

I have now also hinted to Samsung about our hobby and the need for a 43-inch 3D monitor, since they are already working on their 3D monitor that uses autostereoscopic 3D and head tracking. Here is their answer:

 

'Thank you so much for reaching out to us and for sharing your passion for the virtual pinball community.

It's truly inspiring to hear how dedicated your community is to creating the ultimate pinball experience, and we appreciate you taking the time to explain the possibilities that 3D screen technology could offer.
 

We completely understand how important the right display is to bringing that immersive 3D experience to life — especially on a real pinball cabinet. Your enthusiasm and insight into the potential demand, not just from the pinball community but from the broader gaming market as well, have not gone unnoticed.

We have forwarded your request to the relevant department within our organization. Should there be a mutual interest in exploring this further, they will reach out to you directly.

Thank you once again for thinking of us, and we wish you and the virtual pinball community all the best.

Kind regards,'
 

It is not a 'yes,' but it is not really that they are not interested either. What I was wondering is whether VPX already provides this autostereoscopic image, or if an adjustment needs to be made to VPX video rendering so that VPX can display that 3D image? And whether that is easy to do? And the right head tracking is already in vpx?

Are you talking about using a 3D TV as a playfield monitor in a cabinet or just a large screen for a desktop display? I'm not aware of any 3D-capable displays that are engineered for a vertical format. Most of these displays have a lenticular lens screen in front of the LCD to split the left/right image. They don't work when rotated vertically. The other challenge in a cabinet would be the viewing angle as 3D displays are generally set up for best viewing in the center not off to one side (which is how we see the monitor in a cabinet).

 

Now, putting a big horizontal 3D display in an arcade cabinet could be pretty cool.

[mandermannen]

im talking about a 3d tv/monitor in a cabinet. I have no technical knowledge but for i know samsung is trying to give 3d monitors a new live and then without 3d glasses. For i know they have a 32 inch monitor now witch  use autostereoscopic 3d image and headtracking. If they could put that in a 43 inch monitor in portrait mode and vpx can send a videosignal comptable with this, then i believe this would be awesome to the 3d experience of playing vpin. I know that VR is the best but you lose al the goodies like flashers, real dmd, led matixes on a real cab plus the interaction with your envirement. I see pinball more as a social game you play with friends or your wife complaining in the background about the noise of the cab...  but its all if. I hope some tv/monitor builder will come with something great. i also contacted vestel, but no reaction yet

That response wreaks of an AI generated reply and seems a little bit too sickly sweet so I wouldn't hold my breath. I wonder if a human actually looked at your email? Maybe you might get a response from someone a little further up the chain. Sucks that we have to figure out if a real human is actually responding to us these days.

Yeah it is very cool isn't it. Glad its working ok for you. What you mentioned about the "retro" aspect is exactly how it looks, its like viewing an arcade emulator with scanline option. How are you finding the flipper lag, is it ok? Did you turn off all post processing?
Are you using the side by side or top bottom and having the TV handle the 3D or simply setting VPX to interlaced 3D mode? Have you gone into your POV menu and set it up for "Window" mode or are you using "Legacy" mode? Have you set up your screen size and angle in VPX graphics settings? Also have a play with VPX Graphics "eye separation", Im not 100% sure if the values are correct with that regard, there may be a bug there.

Physically set your screen at about a 10 degree angle, similar to angle of real pinball glass (it varies between different machines a bit).

I didn't contact Vesel, but I did contact Technisat, maker of the TECHNIMEDIA TV that previously used the Vesel 3D panels. Unfortunately they were not hugely receptive and just mentioned there were no longer parts available. I cant recall what I asked as I only have their response (I must have contacted them through an online form so have no record of my outgoing email to them)

Autostereoscopic vertical screen lens would need to be tuned to suit the average player position as I think the fresnel lenses are further from the panel surface compared to LG's FPR cinema3D tech (polarised glasses) and as such you get parallax error occuring. I spoke with a autosteroscopic 3D screen developer a few years back and they said that technically it could be done to suit pinball, but development would be expensive. I think we stand better chance with Vesel 4K FPR panel to be rereleased as they may already have all the tech and machinery mothballed (provided it wasn't sold off or lost/dumped)

[mandermannen]

I find the lag not distracting. I turned off all the processing and tweaked the image settings of the lg a bit. I have vpx to flipped interlaced 3d mode and set my monitorsize in the videosettings. Not sure if supersampling improves the image on a fullhd screen but i have it on 150%. I have vpx on windows mode and have the z setting on 75. I tweaked the eye separation but found out that the default was perfect. I also tweaked my nvdia settings and set it to use the nvdia colours, not sure if that make sense. Now the image is perfect. I really hope dat Samsung or i believe asus also will continue expanding their 3d monitor/tv's adventure without glasses, and there soon will be a 43 inch we can use in our cabinets. I dont know if someone here has seen the monitor live in action and how the 3d experience is. Vestel still not responding on my email, i will try it later again

Do you find there is some ghosting more towards the bottom left and bottom right of the screen in portrait orientation? (Likely a result of parallax error between the FPR filter and screen surface. usually the playfield outlanes showing on my screen are not quite right.

I also need to use flipped interlaced. I also seem to remember testing this in 10.8.1 as well and that may have been fixed as I think just "interlaced" was needed in that version.

What is your eye separation setting?

It's very hard to go back to 2D pancake mode after experiencing 3D eh?

Yes i will never go back to 2d. All this effort to make the most beautiful 3d models and then watch it in 2d. I hope the lg will last at long as there will be 3d tvs again. How old is your lg? Yes there is some ghosting left and right but not that distracting. I hope in this new vpe program from freezy we also will have the 3d options. I also ordered 

https://www.pulse-eight.com/p/104/usb-hdmi-cec-adapter

You can let the lg turn on and off with the start and close of Windows. Hope it will work. Im not at home right now but i believe my eye separation has a 63 in it, so 63 or 0,63 or 0,063. What are your settings?

I bought my LG secondhand, maybe 2 years ago. Its an LG 42LA6230-TB from around 2013-14. It runs ok but takes at least 30 seconds to start up from cold (just has LG logo on the screen during boot). I think this startup time is getting longer and likely a sign of a power supply capacitors or something starting to fail. Power on time is something like 34000 hours so its hard significant use over it's lifetime.

I also have an LG 32" 1080p passive 3D which I think is from 2012, cant recall model offhand but its on my desktop and I occasionally use it with Reshade/Depth 3D to run some games in 3D. Bit of a rare beast being only 32" but 3D.

BTW, I tested out VPX 10.8.1 a few months ago and it seemed to be a bit smoother running 3D, so I'm looking forward to that reaching release state and also VPE when it eventually launches.

The adapter you mentioned sounds good.

Hi guys, fellow 3D enthusiast here. In case you are looking for an easy way to switch between anaglyph-3D, polarized-3D (e.g. interlaced), BAM head-tracking mode and non-3D mode in VPX, you can find some alternative run mode wheels and scripts for PinUP Popper here:
