Active-shutter 3D TV glasses have two basic deficiencies when it comes to image quality and they have been and still are, refresh-rate related flicker and “crosstalk”. Since the lenses are designed to dim each lens very quickly and in sync, any other illuminations in your viewable area will appear to “flicker” about you. This has the effect of giving you a headache and making your ever shifting eyes tired.
You can turning off all the lights in the your viewing area, but this is only convenient if you have control of all room lighting from your viewing position. “Crosstalk”, occurs when the 3D TV and the glasses can’t switch between the right-eye image to the left-eye image quickly enough and they get “out of sync”. You end up seeing “ghosted” images in both eyes which is the result of seeing a bit of each image when you should only see one. Many times just readjusting yourself in the seat can cause a problem.
One of the known parts of this 3D TV science is that the larger, and hence wider, the 3D screen the easier it is to correct these two major 3D setbacks. Makes you wonder why recently manufacturers are trying to grab the gamers attention with smaller 3D TV screens when they might end up being pickier than the movie entertainment crowd is. With 3D TV bigger is better without argument.
