LG LN5700 vs LN5400

The main advantage the LN5700 has over its opponent is the Smart TV capabilities it offers: the Home Dashboard 3.0 is present and various cards are used for organizing the content. They are the same as in the higher-end sets, except that the 3D World category is missing since it’s a non-3D model. There is also an application store and a full web-browser. Unfortunately, only the standard remote is included with the LN5700, so unless you decide to get the Magic Motion one as an optional accessory, navigating through the applications will be quite tedious and you won’t have the ability to use voice commands, as the standard clicker has no built-in microphone. Of course, you can take advantage of the smartphone remote support (by installing the LG TV Remote app), and use your mobile device for controlling the TV instead.

The LN5700 has a dual-core processor, while the step-down model has a single-core one, which is not surprising considering the LN5400 lacks any sort of smart TV functionality, so any additional processing power isn’t needed. This doesn’t affect the picture quality since they both have the Triple XD Engine, which is suite of picture enhancement tools aimed at improving contrast and color, in addition to reducing digital noise.

There is a difference in the number of HDMI inputs: the LN5700 has 3 (side facing) while the LN5400 has only 2 (1 side and 1 rear). The former one has 3 USB ports while the latter one has only 1. Only the higher-end set supports the Intel’s WiDi (Wireless Display) technology.

Except for the 32- and the 39-Inch class models, which have panels with 60Hz native refresh rate and no motion compensated frame interpolation, the remaining devices (the 42-Inch 42LN5700, the 47-Inch 47LN5700, the 50-Inch 50LN5700 and the 55-Inch 55LN5700) from the LN5700 series, as well as to the entire LN5400 range (the 60-Inch 60LN5400, the 55-Inch 55LN5400, the 50-Inch 50LN5400, the 47-Inch 46LN5400 and the 42-Inch 42LN5400), have a native refresh rate of 120Hz.
