I myself am not a big 3D supporter, I think that it’s going to be a niche market and that all it going to be.
I have not spend a lot of time looking into a direct answer to your question but I know that when Mitsubishi showed of it’s 3DC-1000 3D converter box at CES, it was compatible with Samsungâ€™s 3D-ready televisions. Both companies use the same checkerboard 3D format. But Mitsubishi modified the box to restrict compatibility to its own 3D-ready rear-projection DLPs. Thanks to new EDID messages sent with the converterâ€™s HDMI signals, Samsung will no longer be able to receive 3D in HD via the Mitsubishi box.
Some of this converter processes that you see also rely on a PC with a high-end GPU in the mix to make it happen. I wish that I could give you a more direct answer, but I have not spent a lot of time divulging into the 3D realm.
