I'm looking at getting a 40-42" 3D tv for my bedroom. I have been doing a bit of research but keep getting conflicting advice! My budget is only £500 top end so i'm looking for a budget set. The screen will be mostly used for watching sport and films with a bit of gaming although this isn't such a big deal to me. So i'm basically wondering...... a) is passive or active technology better? I've head active can give you headaches but passive don't give as good/sharp an image on 3d content? b) would a plasma or LED screen be better? c) the screen will be wall mounted so will be raised above eye level (the bottom of the screen will be about level with my head when i'm sat at my desk, which backs against the wall the tv will hang from) so will this effect 3d viewing? The screen i have seen that i like the look of the most is the Toshiba 40TL868G but i can't find any reviews online. Anybody got an info on this screen? Thanks in advance.
