A different brand of glasses could help too, but it's best to make sure it's not the projector's settings first.
A decent way to see if the glasses are part of the problem is to look at a very dark or black picture/scene. Even if the projector is set weird, that black should still look pretty black. If the glasses are passing a light they aren't supposed to be, then the black will have a noticeable green tint as well.
If blacks have a green tint, it's time to shop for a different brand of glasses.
Thanks for your input. I found some time to test out the suggestions to made, and the resulting output still looks green when viewed thru the glasses.
Note that in both examples below, like before, the green effect is a little more intensified than how it actually appears, but only by a small margin ..
