There are several reasons why you may not see a 3D effect, or why the 3D effect may not be optimal:
1. Ensure that you have the correct 3D glasses on, and are sitting in the ideal position (see Getting Started).
2. Adjust the tilt of the display while looking at a 3D image. You should notice the image becomes clearer at a certain angle, with any double images reduced or eliminated.
3. Ensure that the laptop's display resolution is set to 1366x768.
4. When watching a 3Di DVD, press "D" to switch between "3Di (Left)" and "3Di (Right)".
5. Ensure that you are not in 2D mode. Press "3" in TriDef 3D Media Player or "Alt+Shift+-" in TriDef 3D Ignition to switch between 2D and 3D mode.
6. Ensure the 3D Scene Depth is greater than 0.
7. It is believed that approximately 10% of the population are "stereo blind" and cannot perceive stereoscopic 3D depth effects.
