Sony KDL-46NX720 LED LCD 3D HDTV Review$999.00
The KDL-46NX720 has a native resolution of 1080p and can display all standard NTSC resolutions.
The viewing angle of the KDL-46NX720 is fairly poor, which is typical for an LCD-screened TV. Even though most marketing materials will tell you that a TV has some ridiculous viewing angle like 178 degrees, the fact of the matter is that the KDL-46NX720, like a good many LCD TVs, will lose over 50% of its contrast at an angle of 21 degrees from center on either side.
The KDL-46NX720 has a somewhat reflective screen, but it does a good job on minimizing glare and reflection brightness. When a strong light source is pointed towards the screen, it appears a bit subdued, which reduces the annoyance factor greatly.
The KDL-46NX720 has a handful of additional video processing features, some more helpful than others. Among these, Sony tucked away a really awesome feature: LED local dimming. For those of you who aren't familiar with this feature, if you have an LED backlight, it's possible to program the TV to dim or brighten each light-emitting diode depending on the picture in front of it, boosting the effective contrast of the picture without actually changing the performance or programming of the TV. It's not perfect, as it can lag a little bit from time to time, but it is pretty cool to mess around with if you want an even wider contrast ratio.
When we enabled the LED Dynamic Control setting in our tests, the KDL-46NX720's contrast ratio exploded, giving us a deepest black of 0.01 cd/m2, and a peak brightness of 311.13 cd/m2, for a total contrast ratio of 31113:1. Granted, it isn't realistic to expect this to work well with content that has a lot of motion in it, but still pictures and slow-moving pictures might benefit from this video processing feature. If you own this set, you may want to play around with this a bit before deciding if you want to keep it on, as it can get distracting in moving pictures.
