It gives pretty decent results, providing you're not expecting the processed 3D images to equal a native 3D image. You can adjust the depth of the 3D processing - most people like it somewhere between 5-7, but it's personal taste.
As to the movie, anaglyph is different than active shutter 3D. Anaglyph can be used on most TVs, active shutter requires, at this time, 240Hz TVs.
I've never tried either with a video game.
after a long search on the internet. i still have 2 questions about 3dtv.
1)does the 2d to 3d convert gives you good results? because yea, the 3d ready movies or games looks fantastic at any 3dtv, but there are few very few... here is a video with a 2d game and how this looks through anaglyph (red-blue glasses need)does the
3dtv can convert 2d games to 3d in this gratifying level?
2) does the 3dtv convert everything in 3d like ps2 games or old pc games? or only hd signal?
if anyone knows please tell me.
