I have a client with an NC2000 with RealD XL, wants to project 3D using dual DVI input where each DVI cable carries one eye image, both in 1080p.
I can get an image with 3D working but the image is stretched roughly double height so objects are stretched thin and cut off top and bottom.
Has anyone managed to get dual DVI 3D working? If yes ... what title settings did you use?

I did a setup using dual DVI with a Barco 20C. There is a dual DVI 3D setting in the input choices on the Barco. One thing Barco said is it has to be 1080P resolution and they have to be properly synced to each other. Ran into this problem with the installation I was doing. Left eye and right eye were coming from separate PCs. Had what looked like one image was out of frame with the other. They got a sync card that fixed that problem.

I would check your resolution and also the input settings on the title.

Well, the NEC only has "3D twin 8bit" as a format choice with actual 3D projcted when you select dual/twin DVI input. That's the one that gives the streched image with both eyes projected. All the other format choices give a good sized image but no 3D - the XL shows 144Hz sync but only one eye image is shown.
