Summary of 3D Observations on the 65HX950:
1) The Playstation 3D glasses are significantly superior to the Sony Titanium 3D glasses. The PS glasses are polarized, the Ti glasses are not. (This is easily confirmed by looking at an LED clock with 3D on). This means that tilting your head a little bit in 3D will totally change the colors on the Ti glasses, but NOT the PS glasses. Additionally, although the PS glasses are ever so slightly darker, the colors are richer and pop more. The Ti glasses tend to put a slighly dull yellowish patina on the picture. Most importantly, crosstalk, while still there in equal amounts, is far less noticeable on the PS glasses. It's more faded somehow. Finally, the PS glasses are much easier to wear if you have prescription glasses like I do, and block out more light. The Ti glasses are just a bit more comfortable on the nose. That's all they have going for them. FYI, Samsung's bluetooth 3D glasses are also polarized.
2) The movies I tested were Open Season 3D and Avengers 3D. The first has very little crosstalk and looks fabulous. So does Avengers, though in some scenes the crosstalk may be SLIGHTLY more. Not a huge deal. The 3D depth is very good. However, unless you turn on MotionFlow, 3D movies flicker quite badly!
3) For 3D games, the TV forces off MotionFlow and the benefits I think it provides to low framerate 3D games (mainly judder and ghosting reduction). However, even though MotionFlow is off, flicker is not introduced, unlike for movies. Probably something to do with the 24 vs 60Hz difference. The problem is that crosstalk is very noticeable for 3D games. If you max the 3D effect sliders in games like Halo CE or Uncharted 3, they become almost unplayable, especially Halo CE. However, there are two things that can be done to reduce the crosstalk: 1. Use the PS instead of the Ti glasses. 2. Lower the 3D effect slider in each game's settings. This has the biggest effect on crosstalk, going from extreme crosstalk to almost zero crosstalk. Of course the tradeoff is a smaller 3D effect. I have no idea how my Samsung plasma was able to virtually eliminate crosstalk with the 3D effects maxed. Perhaps the plasma tech or the bluetooth tech helps. I should note that my previous statement about 3D games being stuck in Game mode is false. You can change to any scene mode, and you enable local dimming in Game mode too, just not MotionFlow.
Also, I've ruled out cables or receivers as having been responsible for the crosstalk I'm seeing in games. It's purely a function of what I said above.
I'm sorry I don't have much to say yet on the 2D front. It's just amazingly good. The problems I've encountered so far are: 1) Some clouding when Local Dimming is off. 2) Potential light, but static DSE (will compare to my old zero DSE TV tonight to rule out a source issue). 3) The Advanced Contrast Enhancer tends to crush blacks unless you turn it off. Also, I'm not sure what Reality Creation really does besides massively increase picture sharpness. The Reality Creation may be responsible for the slightly overprocessed "fake" effect that someone complained about earlier when seeing it in a showroom. Every time I think its too overdone, I turn it off, and its like I'm looking through a blur filter, even though that is actually the "normal" picture.
