LG 47LV4400 LED LCD HDTV Review$999.00
The LG 47LV4400 has a maximum contrast ratio of about 1158:1, which isn't amazing, but overall is definitely good enough. A deepest black of 0.31 cd/m2 is what ultimately brought its contrast ratio down. Generally, we like to see a luminosity of 0.1 cd/m2 or less, and 0.31 cd/m2 just isn't very dark when compared to similarly priced televisions. The 47LV4400's contrast ratio was boosted into acceptable range by a peak brightness of 359 cd/m2, which is really pretty bright. More on how we test contrast.
Color & Greyscale Curves
These curves showed us that all of the 47LV4400's shadow details and hues lack definition, with mild success through mid-tones which in turn ramp up too quickly and strip the highlights of their detail as well. More on how we test color performance.
After numerous color temperature tests, we discovered that what initially appeared to be an equipment problem was, in fact, this TV's massive color temperature error. This kind of error is definitely visible, and we frankly find it hard to believe, but the proof is in the testing. More on how we test color temperature.
Despite its massive temperature problems, the 47LV4400 performed well against the rec. 709 gamut, with almost perfect green and blue and slightly oversaturated reds. But it completely missed the white point, which explains why it did so poorly on our color curves and color temperature tests. More on how we test color temperature.
Perfect screen dynamics are always applauded, but are also very rare. The 47LV4400 wasn't perfect; it did not exhibit a largely noticeable amount of local dimming, but overall maintained a consistency of 0.23-0.25 cd/m2 during our tunnel contrast test, regardless of the amount of white or black on the screen. We tend to prefer consistency over wild jumps in contrast performance. Likewise, its brightness only diverged by a small amount during our white falloff test, maintaining at least 355 cd/m2 during mostly black screens. What this means is that, regardless of content, your brights will stay bright and your darks will stay dark, without any sort of noticeable auto-dimming or false brightness (and here we all thought this was only important within the realm of washing machines). The 47LV4400 is vigilant, if anything. More on how we test picture dynamics.
