I am a Viewsonic Projector owner PJD-6251 3D ready. I bought 2 pair that arrived last week. I have spent a week adjusting all of my settings trying to get the glasses to hold a sync. My screen is 90". If i am sitting 2-2.5 feet from the screen it may or may not hold a sync most times it does not. if i move to 3' after 10 seconds the glasses autoshut off. Fully charged, both pair of glasses do this. This is a projector that has 3700 ANSI lumens. So i don't think...
