Here is my take
What to change (NX720) and (HX820) (settings for the HX820 can be used for HX920 as well!):
Light Sensor On (all others OFF) to NX720 only!!!
* Light sensor/Ambient sensor should be used to dim the backlight if there are edge failures such as the ones
commonly spoted on the HX820 models' backlight leaks. They almost fade totally away if used with the settings bellow.
It also makes the screen shine when it's totally black or when parts of the screen fade to black, showing
Beautiful reflections on it when it's all black. If backlight is too apparent or if brightness is too much, that wont happen.

All of the settings above were a result of consistent testing using a wide array of videos on both NX720 and HX820
and all of the configurations fine tuned using suggestions posted on the sites above with the main objective of hidding
the backlight on the sets
while maintaining a screen that has soberb brightness but displays accurate blacks (as possible as edge led can do).
For better brightness don't use Ambient/light sensor (keep the rest);
For perfect blacks and no sign of backlight use the sensor but brightness will suffer (recommended for dim rooms)
For 3D, the set adjusts backlight to MAX automatically.
For each input should be seleted HOME so it's possible to go to the picture proprieties for each input
so you can change each of them.

If you're too observative, I didn't let go most of the standard options on the set,
nor let go of the Sony original imaging processings of the Standard properties; in fact
we can use them to our own good. Instead of turning it all off and ending up with a lifeless picture,
all of the Sony processings actually make a better picture, but it's necessary to adjust the backlight,
and WARM 2 tint so it displays the nearest perfect Kelvin rates so we don't end up with a non-real image
on the set, that kind of bluish image that looks un-real (the kind of image we all see at stores...).
Another thing I tried had was to hide the backlight as much as possible which keeping brightness...
which prooves almost impossible -- brightness must be sacrificed to hide the backlights...
Fast review of the tvs:
Both NX720 and HX820 are perfect to many standards.
The NX720 has, surprisingly a better image than the HX820 regarding how it hides the backlights
But color acurracy is way better handled on the HX820, so is movements and internet video, also
The quality of the image and display are better.
The gorilla glass of the NX720 is less resistant than HX820s' ... The table top stand from NX720
Is less resistant than the HX820s'
It scared the hell outta me to turn the light sensor/ambient sensor on them. I know that it will
Display better blacks but seriously it scared the hell outta me. i've seen some sets starting to turn on and off
By themselves and I think it has to do with the sensors getting broken.
Sony should improve it's Bravia platform delivering videos and music through it. It's just hella beautiful;
I love the Home menu, all of the menus are classic and have a nice touch to it, they are intuitive and sound
Both tvs have great sound despite being so thin, and if you turn on the Surround they get a bit
Of "WIDER" sound stage.
It sucks that the NX720 remote was downgraded from the 2010 model, so it's the HX850 this year...
It looks cheap and sony should not do this to its HX models... I love the huge, awesome control from the HX820.
If they could they actually should do it bigger!!! It looks very powerful!
Do you guys know what sensors were taking out from the HX850 model? It breaks my heart to hear how they've
Cut stuff from this awesome set!
