I spent some time tonight in 3D mode. This included Avatar on FIOS HBO/3D in side-by-side format and Despicable Me from a Panny 3D blu-ray player.
1st, I think we all know, broadcast side-by-side is half the resolution of blu-ray, so it's not an apples to apples comparison, but for the sake of seeing how things worked differently, it was worth exploring.
Blu-Ray 3D Source:
Was very good. My only complaint would be ghosting at various depths of field. If you adjusted for ghosting in the back of the field of view, the front ghosted. If you adjusted for the front, the back ghosted. No changes to any other images settings made a difference.
Motion Flow standard & smooth are available and are needed to eliminate a very slight flicker most apparent on bright white images. Clear & Clear Plus were not available. The Motion Flow under 3D does add an interesting hesitation on vertical pans, which looks like a 3:2 cadence if you know what I mean. Only turning Motion Flow off would fix the vertical panning artifact. The flicker may be the result of the display only being 120hz panel. I'd like to try other 3D glasses than my BDT100 glasses to see if the flicker can be tweaked in the glasses setup. Honestly, the flicker becomes transparent after awhile, but it's something you notice at first.
You can access the SCENE menu and select any of the scene modes and adjust from there.
One thing I found very interesting... some of the image processing features I would ordinarily leave turned off, actually helped with the 3D image. For instance Advanced Contrast enhancement actually worked very well on HIGH. It not only add some depth to the image, it brightened the image as well, and every little bit of brightness helps. I also raised sharpness back to 65 and played with Detail and Edge Enhancement. These also looked very good on 3D, helping to add depth to the 3D image. So, I would suggest experimenting with some of those features you would ordinarily leave turned off.
All in all the 3D performance was pretty good, but not as good as our vw90es projector and I'm sure not as good as some plasmas. But it's good enough. I would like to see a HX909 or HX929 in action for comparison.
FIOS 3D side-by-side Source
1st let me say side-by-side is sub standard in so many ways, but there are no other broadcast 3D alternatives at the moment. So we make the best of the offering. Aside from the inherent issues with broadcast 3D, the ex723 3D performance was pretty good. Same ghosting issues with elements at various depths of field.
Like Blu-Ray 3D... it is also worth turning some things on to help with the image, however, be careful about a build up of noise and compression artifacts inherent in the compromised source signal. While the Advanced Contrast still looks good, extra sharpness & detail/edge enhancement will bring out the worst artifacts in the source.
MotionFlow is not available in side-by-side 3D mode. Then again there is no flicker either. I'm not sure why there is no flicker like there is with the blu-ray 3D source and MF turned off. Probably because the FIOS HD is 60hz.
Over all, I am OK with the 3D performance. I know Despicable Me has some inherent ghosting issues, so I look forward to seeing some alternative 3D movies on Blu-Ray. I wish I still had my copy of Avatar. However, based on the similar ghosting I saw on the HBO/3D Avatar, it may not get any better.
On a side note regarding the blue tint: It's not the darkest black level that has a blue tint, but rather maybe the 10-20 IRE range. I found going into White Balance and setting the Blue Bias to (-2) helped a lot. I was then able to raise brightness a click to 48 to restore the lost detail. At some point I will calibrate with Calman and see how the grayscale tracks. There is definitely a blue tint but it can be quickly tweaked with blue bias. For now, I would not try increasing the red/green bias unless you can measure the grayscale track. It's liable to boost your black levels in a negative way.
The more I play with the ex723, the more I like it AND the more I wouldn't mind investing in a higher end Sony. Kinda of a contradiction I know, but there is something about the ex723 that satisfies even though I know it could be better. I guess it's because the ex723 easily out performs our old Sony CRT RPTV, but is not as good as our HT projector.
A note regarding SCENE Modes Be advised each SCENE mode offers it's own register(s) for storing image adjustment settings. This provides a great deal of extra set ups for different needs. Some of the SCENE Modes disable important features, like Game and Graphic mode turning off Motion Flow. Definitely check it out as a way to have more than (3) setups at your command.
