Where did you find a 3D version? You also piqued my curiosity on the glasses (hadn't heard of those) so I googled them. Is it a 'big' image that you feel like you're viewing - or is it more like watching a 55" TV from across the room?
Sorry, didn't answer your second question. I would say that if you are in a dark room, it is like watching a high quality 45 inch screen from about three feet. I am currently watching a 32 inch monitor from about three feet, and the OLED image is about 50 percent larger.
It has some pixelation, but that seems to have diminished as the glasses have gotten more use. I don't notice it much once the program is on, and the picture has OLED beauty i.e. saturated colors and outstanding blacks. With 3D sources, the picture is really nice, because you get 3D with no artifacts, very natural looking.
However, I don't think the visors are for everybody, they require some adjustment and do put some pressure on the face/nose. I use them for Playstation gaming as well.
