Hey,

i finally have my Marquee blend working using two 9500 U, GTX480--> Quadro 6000, nvidia 3d vision with shutterglasses , mosaic and immersive display pro. 2236 x 1080 x120 (139kHz) and very short vertical retrace timings.
Projectors work fine with these settings.

Everything is great, except a ghosting issue. On the lowest 10% of the image, the stereo separation does not work.
-->Glasses switch too early.

My attempt was using a µC to delay the sync pulses for the glasses about a ms, fine tuning expected.
But if someone here tells me that there is an easier option for it, i'd be very thankful.

Sure, it would be possible to use a GTF based timing, but i guess that would not be great for the Marquees, since i'm stretching the "130kHz max " that VDC gives already to 139kHz.
And honestly, i'm glad that i'm done setting up the projectors and software. No need to go that road again.
My hope is to find some hidden features in the nvidia 3d vision driver to delay the glasses sync pulse.

best regards, Julian

I know this thread is old but did you ever get this set-up working for 3d blu ray movies?

Hi,
the setup already was working in 2020 like written above.
If your question is about the ghosting issue: yes, we used an arduino to delay the sync pulses,
so we could solve that too.
