Just like it was about a year or two ago when LG released the PA70G with a half baked 3D set up when you had to jump through hoops just to get some kind of 3D going but not all 3D formats.
That was until ? LG released the LG PA75U when you just simply plug and play and you had 3D with many different 3D formats, so as long as your player or input device had the right format.
I would venture to guess it's the same with the PF85U except the PF85U did not come with 3D but perhaps later this year in September LG might ? maybe ? release the Korean version the PF87K in the USA as the PF87U ? with a working 3D with many formats to choose from.
But in this day and age why released something with a half backed 3D set up ?
I felt sorry for those who bought the LG PA70G and had to go through all the trouble just to get some kind of 3D going.
