I'm not comparing the Quest to the Pico 4. The Pico 4 easily beats the Quest on resolution but it's irrelevant because A 3D blu-ray is 1080p, or at most 1080p per eye. I can get every piece of information from that disc, and even increase the visibility of that information before it gets downscaled to native resolution. As an added bonus, downscaling nearly always increases the perceived picture quality.

It doesn't make sense to compare an early generation pentile OLED VR screen to a passive LG 4K OLED. With post-processing I can begin to match it in detail, especially because I'm viewing on an IMAX sized screen. But with SDE and other VR limitations my guess is that the LG will look better at HD resolution and above and I wouldn't be confident in comparing the two, especially without seeing the LG OLED screen first.

I would love to have the clarity of a 4K OLED on which to view 3D. But at the same time I think I would miss the much larger screen. That's only a guess on my part, but in general 3D seems to work better on larger screens and IMAX is much larger than any possible TV size available.

I'm not comparing the Quest to Pico 4 in general either. I'm comparing for movie watching and there is no way you're getting every piece of information out of a 1080P per eye disc to the Quest 1 unless, like I said, you blow the screen up to gigantic proportions, far higher than an Imax screen. The higher resolution is not at all irrelevant as it lets you view the full 1080P per eye information on a far smaller virtual screen that you can see all at once without constantly swiveling your head around. I've directly compared watching movies on Quest 1, 2, and pico. Have you?

You're right about the 4K Oled not necessarily being a better 3D movie experience. Not only do you have a smaller screen but you also have crosstalk, which the VR headsets don't have any of. So I think with the Pico4 I prefer the movie experience to my 4K Oled. Now I still can't watch with people, but my wife doesn't like 3D movies anyway so I usually just watch them on the plane while I'm traveling for work.

No need for that because I am rendering and post processing the image with madVR.

Why would I want to give up the immersion of a large screen to watch on a smaller screen? It's why cinemas still exist in the streaming era. Plus with 3D, the larger the screen, the better the effect.

I've directly compared my Quest to the HTC Vive Pro 2 which has 2.5k per eye. I returned the Vive Pro 2.

According to the head of the ISF, contrast is the number picture quality factor. So while I'm generally a high nit LED guy, I do understand why OLED TVs are generally thought of as being better. I'm not saying that the Pico 4 is bad, I almost bought one myself. But I'm very happy with the high contrast, great colors and excellent detail I'm getting right now. But nothing is perfect and I'm always looking for potential options.

What does this even mean? Rendering and post-processing doesn't have anything to do with the actual resolution and information displayed. Even if you're artificially enhancing the image, it should look even that much better on a higher resolution display.

Ok, you're not understanding what I'm saying. You say you watch a film at Imax sizes, I'm saying to not lose any quality watching on your quest you'd have to watch it at something like 4 times Imax size, which is completely impractical as you'd only be able to see just a portion of someone's face without having to swivel your head all around.

A vive pro 2 is a poor representation of a higher resolution headset. The lenses are horrible, I returned mine as well since it looked worse overall than even the Quest 1 and 2. A headset with better lenses such as the Reverb G2 or Pico 4 is much better.

It's great you're satisfied, I'm just saying don't make these definitive statements with such certainty when you haven't actually compared the two.

A 1080p image might look better upscaled on a 4k screen because more of the available source information is viewable from the same distance. But the information itself doesn't change. It's about what can be perceived at various distances or on different sized screens.

I understood exactly what you said and it's wrong. A 4K HDR image will nearly always look better on the same screen size partly because of the increased resolution but mainly because of the increased contrast ratio. That's why the majority of 4K HDR reviews state HDR as the major improvement, not resolution. Contrast is king. Also, I think you are basing your opinions on basic linear math, but the math behind human perception is not linear for obvious reasons.

I've seen the same scenes played on non HDR 4K TVs and good HD TVs and at normal viewing distances there's little difference. So let me clarify. I would love to have the extra contrast that HDR brings and the upscaled resolution to increase the perceived resolution. But failing that, I instead use software rendering and post-processing to bring out similar levels of details. This works very nicely with high quality sources like blu-rays. But with low quality sources this actually makes the picture look worse because it highlights the flaws lol. I use a separate display profile for those movies.

PSVR 2... OLED screen, 110 degree FOV, support for 4k HDR. Let's hope Sony add support for 3D blu-ray which isn't currently supported on the PS5 and then we will have a winner for VR movie watching IMO.

Yeah I've been following its progress. Could be a winner but it's still too expensive, at least until a new PS5 slim appears. SDR might still be an issue. The other issue would be lack of decent viewing software which according to owners of the original PSVR was a major issue.

Oh I see. It's going to be hard to beat the IMAX cinema on Steam Virtual desktop as well.

I love the screen choices in the Steam version but I've recently gone back to the Quest app again lol. I miss the extra screens but now that I've sorted a few things out, the picture quality is actually better. It's probably been like that for a while now but I was so fixated on the Steam version (which was initially better) that I didn't notice.

[cdx47]

I recently picked up a used Samsung Odyssey Plus. I was hoping this would be my ideal HMD because it's basically a Quest with anti-SDE and no compression. Here is what I have found so far.

Pros:
HDMI: No compression, no banding, aliasing minimised.
SDE filter: SDE very much reduced. Wasn't a major issue for me the difference is obvious when compared with Quest.
Very comfortable out of the box, evenly balanced, simple and effective adjustment controls.
Clearly wider FOV.

Cons:
Updated. See below.

[cdx47]

Update to the previous message. I've significantly improved the picture quality, mainly by removing the remaining post processing I needed for the Quest. But Windows itself seems to play a part depending on the settings I choose.

So for Cons:
SDE filter still visible but improved once post processing removed.
Occasionally can see fresnel lens outlines on plain backgrounds.

I guess there is no such thing as a perfect VR viewing experience but this isn't bad at all

[cdx47]

New hardware but back to my old trusty Quest again lol.

HP Reverb G2 and Virtual Home Theater is bliss. Addresses everything I've ever hated about 3d movies and amplifies everything I love about them.

2160x2160 per eye and a laptop 3080 means I can supersample to hell and back and see tack-sharp images.

Now back to stewing over the UHD standard not supporting 3d.

I would much prefer the higher resolution of the G2 to reduce SDE which is why I bought the Vive Pro 2 (with even higher resolution). But there's a fixed amount of information on a disc and I see all of it, especially since my 3080+MadVR allows me to post process almost every aspect of the picture if needed. I would love to reduce SDE but with post processing some of it mitigated and my brain mostly ignores the rest. I may also not be as susceptible to SDE as others.

Essentially for "3D movie viewing", there's nothing the superior hardware of the Pro2/G2 can do that the Quest can't match. But the Quest has OLED lenses which provides significantly better contrast and colors than LED lenses. I found the picture with LED lenses is like what I imagine HDR would be like without WCG colors. I'm not challenging your setup, I'm just laying out my preferences in a techie way

We are both at the vanguard of 3D viewing in VR so I'm happy that you are happy (hope that makes sense).

[Ferretferret]

If anyone has the PSVR 2 headset pre-ordered, let us know if 3D blu-rays work! I'm monitoring upcoming reviews for word on the functionality. Cinematic mode has returned, so, it shouldn't require much effort from Sony.

[xootoo]

I saw a Youtube short review about this today.

There is a big screen in front of you, like with the first device. But 3D is NOT supported.

Its Sony...

[cdx47]

If you are already converting your 3D library to SBS/OU then i recommend the latest version of Skybox for Meta Quest which has great picture quality although maybe a touch over sharpened. The PC version can connect to your HT to get basic 5.1/7.1 audio but has fewer features. I've never liked this software before and to me, the latest Quest version still needs a bit more work but overall it is relatively easy to use when compared to having to do it all yourself like I do.

[cdx47]

Just an update in case anyone is interested lol.
The setup I have been using was:
MPC-BE player using MadVR rendering (with EWA Lanczos scaling and detail enhancement) with SVP software interpolation.

I'm now using:
MPV player running custom downscaling algorithm scripts (Mitchell) with SVP running a custom Tensor Core RIFE AI software interpolation algorithm.

Why? I can now see additional 3D layering in movies that wasn't clear before, and the RIFE AI interpolation algorithm not only provides smoother slow camera pans, but also reduces the weird artefacts that normally occur when using SVP.

Question: Is there a way to adjust the amount of 3D depth in Virtual Desktop? I'm using a Quest 2 and I noticed that when watching 3D movies thru Virtual Desktop, the 3D depth seems much less noticeable compared to watching thru Bigscreen app natively on the headset. I tried watching a Full-SBS clip in Virt.Desktop with both MPC-HC and MPC-BE, then watched the exact same clip again with DLNA streaming to Bigscreen on the headset. No question that the 3D effect was much more noticeable on Bigscreen. But I don't see any VD setting to adjust 3D convergence/depth or anything like that. Is it possible to adjust?

As explained on the main thread; 3D depth and 3D convergence are not the same although that may not be how it is marketed But the simple answer to your question is that I have not found a way to modify 3D convergence with VD.

But as you yourself have seen, the issue is not VD which is just a viewing window, the issue is the viewing software. However you could try Skybox VR instead of using VD. The picture might be a little over sharp but it's much better than MPC with VD. But Skybox doesn't allow passthrough audio so after I failed to match the Skybox picture quality using MPC with VD I switched to using MPV with VD. The results at least matched Skybox VR and in someways are better because I have total control over the configuration. The picture quality is so much better with clear 3D layering, better 3D depth and just an improved 3D viewing experience.
