tested the tv some more today, focusing on smooth motion and movies
the two movies I tested were life of pi 3d and gi joe retaliation 3d
in regards to being able to turn off smooth motion on my 55" with the latest firmware, I had to change the picture mode to computer not gaming mode. changing it to gaming still showed the tv with smooth motion turned on and grayed out, but computer mode had it turned off and grayed out. in addition to this tuning, I also mimicked the settings from vivid mode as I like how the picture looks in that mode. the color temp I prefer cool so I set it to that as well.
now to the testing
with life of pi 3d, I really didn't notice any huge difference between the 2 modes, both looked beautiful, with a slight edge going to smooth motion on as the preferred choice for this movie.
for GI Joe Retaliation 3d, I had a different result. I used 2 scenes to test this. first the fight scene between storm shadow and snake eyes, followed by the mountain scene with the zip lines.
I picked the fast fight scene because I wanted to see if smooth motion will improve or degenerate the picture quality and smoothness of the motion. I have to say that I preferred the smooth motion option here. yes with it off, the action seemed more true to life, but I did noticed some slight video processing lag which resulted to motion stutter. which was very apparent when the shot was zoomed in and the object in motion is fairly large. when they were fighting normal and the shot wasn't zoomed in, then the action seem fine for both. this was the same thing I experienced with normal day to day tv viewing which is also why I left smooth motion on there as well.
for the mountain side scene with the zip lines, the true motion off option is definitely preferred here. the part where the ninjas were jumping/hopping from 1 zip lie to another, the motion was much smoother with smooth motion off than on.
now on to 3D effectiveness: I feel with smooth motion on, the 3d felt more pronounced than when it was turned off. in fact, there were parts where I felt when the smooth motion was turned off, so was the 3d, which is pretty disappointing...
so there you have it, my personal experience with smooth motion is that when watching movies where there are lots of small fast moving objects, turn on computer mode which will turn off smooth motion. when watching normal movies without a lot of action or with larger objects in motion, turn on smooth motion. for 3d movies, leave smooth motion on for better depth immersion.
has anyone figured out the viewing angle issue yet? turning the bright ness to max did not resolve this, still dims when viewing off angle.
