I was recently informed, by someone representing herself as an LG sales rep, that ANY and All 3D TVs would outperform a Non-3D display, in every way. Including resolution, brightness, contrast -ratio, screen quality. She was instant and emphatic about this. I quietly disagreed with her, but I didn't argue , as I had no technical ammunition to the contrary. Where could one find any near definitive information of this sort? Without trying to get on Leo LaPorte's show... Any input and comments greatly appreciated.
