LG 42LS5700 LED TV Review
LG's mid-range LS5700 offers the same great smart features for less.
The LG 42LS5700 tested with some impressive results in contrast width and color consistency. During testing, this TV rendered a deep black level and a great peak white level. Additionally, all of the colors transitioned from one shade to the next quite smoothly.
Both deep blacks and bright whites can be found on the LG LS5700.
The LS5700 has an outstanding contrast ratio. Its deep black level of 0.06 cd/m2 and peak brightness of 298.20 cd/m2 gave it the large contrast ratio of 4970:1. What this means is that the LS5700 can get dark enough to watch in a dimly lit room and bright enough to watch in a space filled with sunlight. More on how we test contrast.
Colors transition smoothly on this TV.
The smooth change from one shade of a color to the next is an area that the LG LS5700 excels in. This graph shows each color's transition from an input level of zero, which is black, to an input level of 255, which is the peak value of a given color (pure red, pure green, pure blue).
The greyscale (represented by black) and green show the best transition; there are almost no fluctuations in these curves. Blue is still great, but achieves its peak luminance slightly too quickly. Red has a gradual change from zero to 255, but gets slightly brighter than the other colors and, like blue, achieves its peak luminance too quickly. These curves are mostly excellent, though. More on how we test color performance..
In addition to an excellent contrast and good colors, the LS5700 has a decent viewing angle for an LED television. It doesn't compare to the wide viewing angles found on plasmas, though. This graph is included below, as well as some from a couple of other tests.
