You and also me have no idea on non-HDMI 1.4 DLP TVs.
But at least i have a similar device: Acer 5360 and not only for games but for 3DBDs as well it needs at least one nvidia emitter. Because unless having that emitter you will never able to install 3d stuff for nvidia.
I have Xpan and Optoma DLP glasses and i can use them with my Acer 5360 without any problem but i have to use one nvidia emitter. (Even my DLP Link glasses do not use that emitter.)
So i think non-HDMI 1.4 DLP Mits owners will have the same issue.
But i have no feedback yet so i can not prove it.
