Are we still limited to 1080p24 or 720p60

[thedude22]

Hey there everyone. I have been out of the 3d gaming scene for many years now but I just got a new projector, Optoma Cinemax P2, and the 3d is absolutely fantastic at 120" with zero crosstalk issues, so I want to get back into 3d gaming, which basically spoiled me and completely ruined regular old monoscopic gaming. I know VR is the new fad these days but I have no interest in this. I want to look at a flat fixed screen and I don't want any head tracking features. I just want the stereo 3d projection.

So I installed the 3d fix manager, which is a cool tool by the way, and it automatically set up an older driver for me, but when I go to set up 3d in the nvidia control panel the only options I see are for 720p @ 60Hz or 1080p @ 24 Hz. Surely we aren't still limited to this after all these years are we? Do I really have to play in 720p? Because 24hz is completely unplayable. Is there no way I can enable full 1080p @ 60 Hz? Even 1080p60 sbs or over/under is preferable to 720p.

Appreciate any help.

Thanks.

You can actually play games in 4K 3D now if you have a 3D-capable 4K TV or 4K projector.

What consumer projector model supports 4K 3D?

AFAIK, all 4K projectors are limited to 1080P 3D support.
With either HDMI 1.4 3D support or HDMI 2.0 1080P@120Hz Frame sequential support.

Although anaglyph or Dual Passive Projection, might be feasible for 4K 3D.

You can also do as this poster does

Thanks for the response and sorry for beeing late. the new projector arrived an it works, 1080p/ 60Hz 3d without emitter. for anyone interested a more detailed instruction can be found here: https://www.reddit.com/r/nvidia/comment ... hout_3dtv/
In NVControlPanel you have to select a "PC" resolution, e.g. 1080/120, not a 3d resolution. now start your game and make sure it runs @ 1080/120, i take msi afterburner. now you want to alt+tab out of the game and change the reg key. if you first change the reg key and then start the game it will be reset by the system. go back to game, turn on 3d in your TVs/ Projectors menu and you should have 1080/60 3d.

If a 4K projector supports side-by-side or top/bottom I don't see why it couldn't handle 4K 3D too.

If you know anything about the old 1080P DLP 3D HDTVs from Samsung and Mitsubishi, they used a DLM mirror array that was less than native.
To achieve native 1080P2D, they had to wobulate the DLM mirror array image with a second mirror.
https://www.popsci.com/00html/article/2 ... obulation/
Due to wobulation, these displays only output Checkerboard 3D.

All 4K DLP projectors use pixel shift to achieve 4K 2D and is basically the same thing as wobulation, since their mirror arrays are also less than native.
Look at the values on page 20 of the mirror array on the 0.47 found in most 4K projectors https://www.ti.com/lit/ds/symlink/dlp470te.pdf
Even 4K LCD projectors use a similar technology.
There is chance that Checkerboard 3D might be feasible using pixel shift, but manufacturers have yet to implement it
or any 4K 3D projector support in consumer models that I know of. Only 1080P support was implemented on all consumer 3D capable projectors that I'm aware of.


I think the best chance would be some of the DLP projectors using a 2X pixel shift with the 0.66 DMD vs the 4X pixel shift of the 0.47
Checkerboard should work, just as it did on the old DLP 3D HDTVs, if implemented by manufacturers.
Feasibly, 1440P@120 Frame Sequential could be supported as well.

Unless Texas Instruments comes out with a native 4K mirror array with full HDMI 2.1 support and 3D comes back in style, I do not think we'll be seeing 4K 3D on consumer PJs.

Correct it only supports 1080p, which is good enough for me. Took me a while to figure out why I couldn't enable 3d mode when my shield was at 4k resolution.

Thanks for the responses everyone. I'll try these solutions out.

According to user manual, additionally to frame packed, your projector is compatible with side by side, top bottom and frame sequential, and you can achieve it at 1080p120Hz.

The best 3D you can have is with frame sequential.

for this, a 3dvision emitter (pyramid) is required I think.

3Dfix manager can do the registry trick for you without the not-user friendly alt-tab + script process:
On 3Dfix manager:
on top-right, select projector.
then, go on settings -> display profiles -> projector profile -> tick the four cases.
+"Link profile to display": choose your projector
+"Screen size": chosse your projected image size.
+"3D display type": choose 3D Vision / generic CRT (active 3D)
+"3D migoto 3D format: choose: Regular 3D vision (Frame sequential)

It should works "out of the box", if not, a EDID hack is needed.

I doni't have an emitter or the nvidia glasses. i have generic dlp link glasses. Would be nice to do 1080p120

[Tullebob]

Would be interesting to hear how well 3d vision is presented on this projector. I imagine it would be cool to play Mortal Kombat 11 with friends on a 120 inch screen with full 3d vision in 1080p/60fps with max settings

Friends... Yeahhhhhh.......

I'll let you know how it is when work gives me a chance. I can tell you that I loaded up some SBS videos on youtube and some HSBS 3d mkvs and it looked absolutely flawless. I never tried the passive 4k OLEDs which I hear are pretty good, but this is my 3rd 3d DLP and they have always been pretty solid with just a slight amount of crosstalk in high contrast scenes.

On this projector I see ZERO crosstalk. None. It's pretty much perfect. My only complaint is it's active rather than passive which gives me a small amount of eye strain over time, but it's a small price to pay.

Hello, the emitter is required for a full 3D vision activation, whatever the kind of glasses you uses. It have to be considered as a drm system.

You can try without it, but if after an EDID hack it still don't works, a pyramid is required.

[3DNovice]

Not necessarily, if you look at that guys YouTube and Reddit post, you can work around not having an emitter.
It looks like a little bit of a hassle, but works. I'm not sure, but I think him or someone made a .bat file to make it easier

How do you do the EDID hack?

[thedude22]

Actually I can't get 3d vision to work at all. Set to 3dtv play. My projector goes into 3d mode when the test app launches, but the image is jittery and unstable. It doesn't look right at all. Everything looked normal during the setup process.

[thedude22]

Attempt number 1, Destroy All Humans, CTD on every attempt to start the game.

This is such a PitA. Spent all morning trying to get it to work and didn't get to play anything. I don't have the time or patience for this. I guess the dream is dead.

[thedude22]

Managed to get Destroy All Humans to load. But there is no 3d. It says current mode 1164x640 or whatever is unsupported. But both my desktop and the game are set to 720p. I don't get it. Will try a different game.

[3DNovice]

Do you have two HDMI inputs, one being HDMI 1.4 (3DTV Play) and the other HDMI 2.0 (Generic CRT/Frame Sequential)

Be sure to be using the correct choice for desired results.

[thedude22]

I was using the HDMI 2.0 port on the projector. It has a third port which is 1.4a. Should I use that? At the moment I'm just trying to get it to work at all with nvidia 3dtv play at 720p. I haven't even looked into 3dmigoto yet. I have no idea how to install it.

Not sure what is the hdmi version on my laptop. It has an nvidia 1070 in it, so I assume 2.0.

It's weird. It's like it's cropping some of the resolution off the edges. IDK why. I noticed after setting up 3d and changing display mode, the desktop size would sometimes extend beyond the edges of the screen also. This doesn't happen normally. I'm guessing this is also why the test app is not working right. It's not in the correct display mode. The weird thing is the setup process and picture slideshow after it all look fine.

[3DNovice]

The HDMI 1.4 port will be the only port that supports 3DTV Play.

In the Nvidia control panel switch scaling from display to GPU or vise versa if possible and/or use the resize desktop option
