What can be done?
The principle of a pair of Stereo Glasses is :
1. When the left image is projected, the left shutter is open, allowing the left eye to see the left image. The shutter for the right
eye is closed.
2. During the blanking period, before projecting the right image, the left shutter is closed and the right shutter will open.
3. The right image is projected, the right shutter is open, allowing the right eye to see the right image.
The ideal situation is when the opening/closing times of these shutters are in sync with the blanking time of DLP mirrors.
