One week with the 79X900B
I don't quite understand all the negativities here. I am a happy owner of a 79" XBR-79X900B.
It replaced a calibrated Elite PRO70X5FD which developed a dark patch near the center of the screen and I worked a deal with BestBuy via extended warranty. Anyway, the Elite was a great TV and I know what "inky black" means. I was debating whether to get the 65X950B, but once you get used to 70" you just can't go smaller so 79" was it, ordered it sight unseen...
The settings of 79X900B out of the box were pretty good when checked against the "Digital Video Essentials" DVD. (you see, I am old school...)
After a week of tweaking I have settled on the following for now and perhaps get a professional calibration later. Instead of turning off the Eco light sensor I chose to keep it on and tweak from there to minimize the amount of changes from the factory default.
Light Sensor: On
Picture mode: Custom
Backlight: 8 (was 7)
Picture: Max (was 90)
Motionflow: Standard (was Off, tried Clear but decided to go Standard)
Adv. Contrast Enhancer: Low (was Off)
LED DynamicControl: Low (was Off)
The main sources are Verizon FiOS STB, OPPO BDP-95, Apple TV, all hooked through an Integra DHC80.3 A/V controller. I let the TV do all the up conversion even though the Integra has 4K upscaling. This is something to play with later.
I have a FMPX10 on order, can't wait to enjoy 4K to the fullest.
I was actually happy with the 3D, watched Avatar on 3D and thought it was better than the Elite (active 3D).
In the end it will be personal preferences and as long as you know the limitation of current technology, like Ron, I am happy with this set. The 4K clips from YouTub were amazing.
