The issue I was getting with my Sony glasses suffering a glitch every few minutes may have been solved by switching off my WiFi router which is my cinema room. So far no glitches when it is off. I'm monitoring the situation. The Xpands still don't work with brightness on Standard. I'll need to investigate this problem a bit more.
I did not do a "calibration" but did learn a lot about 3D settings last night . The movie The Great Gatsby 3D was perfect for making these adjustments.
First and most important is that the most significant way to reduce ghosting is to turn off motion flow all together. From the various tests I did, motion flow affected ghosting to a high degree, 3D brightness too but the difference was much less .
There are levels of sharpness, contrast and brightness that affect the cross-talk as well, you can pause certain scenes and see a ton of cross talk , then slowly adjust each setting first individually and then in combos to see the results .
At the end of the movie Gatsby, a black and white scene will change into a colored Art Deco frame work , then expands into a 3D image and credits will start rolling. If you pause about mid way into the credits and look at the framework bottom rear
you will see a significant amount of cross-talk.
When making the adjustments do NOT
look directly at the cross-talk image, instead, look at one of the frame intersections ( the frame lattice we are suppose to see) and use your peripheral vision to pick-up the cross-talk. Takes a bit of practice not to look at it, but when you do it right you will
notice the changes, which, when you think about it , is the way we see cross-talk anyway. Actually , there is also one more scene where a white invitation card is shown full screen with a signature hand written, in black ink. The ghost image on that was almost a mirror image of the original signature. I'm
sure if you could pause on that you would have another fantastic situation from which adjustments could be made.
Anyway, when I did this and starting manipulating the settings you will see very clearly how various settings, modes and intensities will increase or decrease the crosstalk. In the end I had a completely ghost free picture but a little darker than I would normally want. I like a brighter picture, others may
consider this level more natural I suppose. Without motion flow any actions scenes can become very blurry, I guess you have to choose your poison . If you want it bright for 3D a higher gain screen will have to do, I wonder though, will a high gain screen then make the ghosting more apparent again ?
Dam it, this forum has turned me into the cross-talk Nazi
I have to stop this and start watching . Bloody picture is as near perfect as I have ever seen and now I'm trying to find ways to dissect it . Go figure
Saying all of this, even with a little ghosting ( mostly background anyway) the picture is fantastic, lets see now what the Lumagen and anamorphic lens will do to correct some of this.............................later.
