The 3D glasses problem doesn't really apply here. With 3D movie glasses, everything is blocked out except for the 3D images. Some people feel queezy when their proprioception and visual input don't match. It's a little like car sickness. With the screen, they do match, as only what's on the screen is 3D. In that sense, it is like looking at a box with something 3D in it, versus being submersed inside something 3D like with the glasses. tl;dr With the screen you can move your head around and the world moves with it, so there is no sensory mismatch. But turning your head when going into a 3D warp speed starscape with 3D glasses on might easily cause someone to ralph on the poor sole sitting in front of them.
