Actually, I'm not sure about that with the LCD shutter tech. I'm not sure if it relies on both eyes to hide the fact that the lens is being blacked out 60 (er, 24?, 30?, 48?) times a second.It should look fine as long as you use one lens (as you said).
On most content there should be a 2D option, as long as everyone in the room is happy with losing 3D. Though, sadly, the standard for 3D Blu-ray allows for discs that contain a 3D version only, with no 2D option.[/QUOTE]
If it DOES have an effect on looking with one single eye, then it would darken the image significantly, wouldn't it? If it doesn't, I guess you wouldn't notice the blacking out that much. Isn't the frequency increased a lot?
