The Panasonic Viera TX-L55WT50B is the 55" version of the Panasonic Viera TX-L47WT50B, which we reviewed here.

It has a glossy, Edge LED-backlit LCD screen, online services, DLNA and a good media player that supports NTFS external storage devices and most of the HD videos we tested.

It's a highly responsive panel with a ghosting time of 7.5 ms. After setting it to True Cinema mode, the screen displayed a balanced gamma, but inaccurate colours on the pre-release model we tested. Panasonic has assured us that the models that are on sale in stores have been updated to correct the colours. The contrast is far too low, at 860:1, making blacks look washed-out and grey. On the upside, the WT50B shows no signs of clouding (bright patches on an otherwise dark screen).

The IPS-Alpha panel's responsiveness makes for practically no crosstalk in 3D mode, and the 3D rendering is almost as good as any plasma TV.

The sound is just barely average, with a good woofer but mediocre tweeters.

As is often the case with Edge LED TVs, the WT50B has low power consumption.


For more about the Panasonic Viera TX-L55WT50B, please refer to our review of the 47" model, the Panasonic Viera TX-L47WT50B.

Sometimes manufacturers fit the different sized models of a given TV with different panels. In these cases our comments apply only to the model size we tested. This is because the contrast, black levels, colour fidelity and ghosting are all subject to change from one panel to another.

Manufacturers who use the same panel for each model size can expect the same results across the product line. The only factor that could be prone to variation is the brightness, which would produce slightly different contrast. However, according to our tests (and assurances from manufacturers), when the same panel is used the results from one TV can indeed be accurately applied to the other model sizes in the series.
3/5 Panasonic Viera TX-L55WT50B DigitalVersus 2012-12-31 12:00:00

Pros

  • Good 3D rendering and little crosstalk
  • Effective motion interpolation
  • Media play supports most file formats
  • Backlit remote control

Cons

  • Low contrast (860:1)
  • Inaccurate colours on pre-release model

Conclusion

The Panasonic WT50B's image quality is identical to the DT50. All that's changed is the design and accessories. The IPS panel is highly responsive, but the contrast is just too low.

OUR SCORE 3/5
