This model is the 42'' version of the 47'' TV that we tested in our labs, the LG 47LW550T.

Everything we said in the original article holds true--the only thing that's different is the size!

The only exception is that some manufacturers fit different sized televisions with panels from different sources. In that case, our comments are only valid for the panel that we originally tested. Contrast, black levels, colour handling and ghosting are all subject to change from one panel to another.

Manufacturers who do fit the same panel in all of the TVs in a range can expect the same results across the whole range. The only factor which could be prone to slight variation is the brightness, producing slightly different contrast. According to our own tests, and assurances from manufacturers, the results of one TV can accurately be applied to others in the range.


  • Attractive results in 2D and 3D
  • Accurate colours: average deltaE of 3.1
  • Light, comfortable passive 3D glasses
  • Matte display (so not many reflections) and low energy consumption (90 W)
  • One of the best LCD 3D TVs: not much crosstalk and less eyestrain than with active 3D technology


  • Contrast ratio not quite perfect (1005:1)
  • More crosstalk visibile thanon a plasma 3D TV
  • Media player doesn't support M2TS or MTS files


The LG LW550T television only just misses out on a four-star rating because it can't quite deliver the same image quality as its big brother the LG LW650S. That doesn't take away from the fact that it's a great 3D TV.
