oh god just saw this one in 3D mode.Dont know if it was a real 3D demo from LG but it was coonnected to a little box suplied from LG I think it was a HDD device. We can see the lines of resolution from the TV.Not hi def at all!
Yes, I have seen this model in the flesh, I wrote my first impressions in the Home Cinema section, here: http://community.whathifi.com/forums/t/425865.aspx , the topic is called "3D TV first impressions".
This is a TV which uses "passive polarized glasses", the 3D effect seems convincing, but nowhere near hi-def. It's like watching SD in 3D. Yes, I can confirm that the resolution lines can be clearly seen. Also, as you can read in my post, the picture "judders" a lot and proves to be tiring, even after a few minutes of watching their demo.
As a conclusion, I'm not convinced by the current implementation of 3D on televisions. Bear in mind though, these are my personal impressions.
