trioviz infinicolor 3d glasses with standard purple/green anaglyph content?

Not sure if your projector is compatible, but check out VIP 3D Displayer or Theater. They will both cost you many, many, many cases of beer. Like 4 kegs worth.

This is real active 3D, not the colored gel version.

I don't know much content that uses Trioviz magenta/green colour combination. As far as I know Tridef only supports Red/cyan anaglyph.
The only things I know are Youtube which has a green magenta option, and the Console version of videogame Batman Arkham city (not on PC, on PC it's optimised for Nvidia 3D Vision).

Magenta green isn't better than red/cyan, it's still a colour mess, there is no miracle here. The only thing is it may or may not be better depending on the content you use.
Some content show up better with red/cyan, some better with yellow/blue, some better with magenta/green.
I have only tested the Trioviz glasses for a few minutes at a trade show (showing the batman game), they modified to game colours to make the picture easier on the eyes, it looked quite good but the game has very little colour (well it's Batman).
From my experience with other types of glasses, red/cyan is the most consistent when using random content.

IMO you'd be better off buying the Optoma GT750. That projector is better than a 3D ready projector, as it is fully 3D capable out of the box. The ml500 is 3D ready, which means you'll also need the Optoma 3DXL converter box to get all of the 3D formats working with it. When you add the cost of the two together it is more affordable to just buy the GT750.
