It all depends on the model: further on LG passive 3D

Well, there I was, once again incorrectly, thinking that the whole matter of passive 3D was settled. A couple of weeks ago I established, I think, that the current top of the line LG TV, the 55LM9600, uses two different … Continue reading

3D display brightness

Reader Ryan has pointed me at a slightly old (in 3D talk, August 2011 is old) discussion of Active vs Passive 3D technology in Audioholics. Many of the points it makes are well founded, but it also demonstrates a misunderstanding … Continue reading
