To watch a 3D Blu-ray movie, you will need a 3D Blu-ray player, a 3D TV, and a pair of 3D glasses. The 3D Blu-ray player will send a signal to the 3D TV, which will then display the three-dimensional images on the screen. The 3D glasses will help you to see the three-dimensional images correctly.
If you do not have a 3D TV, you will not be able to watch 3D Blu-ray movies. However, you may still be able to watch regular Blu-ray movies on your 3D TV.
