Does the 2D to 3D conversion work for anything?

Yes, but only a few brands have this feature. As far as I know, only LG and (maybe Toshiba?) offer the 2D to 3D conversion feature. They work on anything; Movies, television shows, Music Videos, you pick! It's quite easy and very satisfactory! With just a click on the screen, the 3D TV does everything on its own and converts the 2D image to 3D! This is so useful since it means you don't have to buy separate 3D materials! I'm using the LG LW5600 and have no complaints. You can tell the difference between 2D and 3D right away. I also highly recommend music videos in 3D if you're a fan of music.
