The upcoming 4k passive panels very likely will only display 3D full screen making them worthless
Yes, I fully respect your personal desires for something unique and not common in the 3D TV industry. But, you should not assume that the new 4K Panels will not allow you to do what you want, plus the benefit of improved picture quality. I also recall your vision problems with focus and that beyond a certain resolution, you just can't appreciate.
Now, ( for Trick and others), I was able to duplicate Frank's multiple 3D windows here pretty easy with my Vizio 32" Panel TV.
I only have three applications to display 3D content in the required Line interleaved mode on my edit computer that uses the Vizio as a secondary monitor so I tested with those apps.
1. Stereoscopic Player: Opened an MPO file I shot with my NEX5n in panorama 3D. Used Row Interleaved Right /top
2. You Tube- Displayed one of my SBS / Half 3D videos on my channel but went into the 3D settings and switched it to Interleave, 3D on. Slid the Browser with not full screen window and the browser was in 2D while the video window was in 3D.
3. Power Director allows Interlerleave display, Had to use Media Viewer window on the Vizio as otherwise it goes to full screen.
The Vizio was in 2D mode and with passive glasses each window was in glorious 3D!
When Frank first described this method, I had to chuckle because I recall just a few months ago he was pretty stubborn about Must have checkerboard for the same end use reason! Back then I had finally resolved the lack of SBS viewing mode in the Power Director viewer using this interleaved method, BUT I had never tried it to view multiple windows as Frank has done. I recall the engineers on PD10 not understanding why I got it to work but they accepted that I was finally happy with being able to see 3D with Power Director. I put the Vizio in 2D mode and selected, interleave.
The key requirements here to make this work is twofold, 1. The panel must use a Film Pattern technology which is a film laminated to the front of the screen that projects the picture, all pictures through it in a polarized set of light outputs. The second requirement is as Frank said, a player that offers "Interleaved" output. It's that simple.
Frank- I would not automatically refuse the higher quality 4K monitor, believing that it will not work. These new LED 4K monitors still use the FPR layer on the screens. I asked the engineers at CES about it. The only difference is the number of pixels which should be a huge benefit for you fitting even more windows. For me and others, being able to view full 2K resolution in 3D that normally would get cut in half on the present day 2K panels.
Finally, I found no way to use this method with Vegas Pro as Vegas does not offer an interleave 3D viewing mode. If you got this to work, Frank, I'd like to know what settings you used in Vegas as a matter of education. I don't have a use for multiple 3D windows but it's nice to know the possibilities.
Also, nowhere can I find that interleave is supported or not on my Vizio. It just works, exactly as it does on your LG.
