Can't help but think you guys have been looking at passive 3D, try the active 3D for better resolution.
Using passive I get a headache after about 30 minutes but nothing like that using active glasses.
Using active 3D you can also put it to virtual 3D while watching your regular shows( I do it for sports),
this way you can get a slight 3D effect not as intense as the movies that are made in 3D.
