This model is the 42'' version of the 50'' Panasonic Viera TX-P50ST50B TV that we tested in our labs. For more information about the ST50, please therefore go to our review of the Panasonic Viera TX-P50ST50B.

Everything we said in the Panasonic ST50 review holds true for this model—the only thing that's different is the screen size!

Sometimes manufacturers fit the different sized models of a given television with panels from different sources. In such cases, our comments are only valid for a specific size of a given TV, fitted with the panel that we originally tested. Contrast, black levels, colour fidelity and ghosting are all subject to change from one panel to another. When different panels are used, we'll be sure to let you know about it!

Manufacturers who do use the same panel in all the various sized TVs sold under a given model number can expect the same results across the whole range. The only factor that could be prone to slight variation is the brightness, producing a slightly different contrast. However, according to our own tests, and assurances from manufacturers, the results of one TV can accurately be applied to other sized models in the series when the same panel is used.
Our Readings

After trying and testing the various options in the internal menu, for watching films, we found the best bet was "Cinema" mode. Then switch the colour temperature to "Warm" for a near-perfect image.

For low-resolution sources (DVD, SD TV, etc.), you're better off leaving upscaling to a latest-generation console (PS3, XBOX 360, etc.). If you don't have a console, try upping the sharpness setting to artificially increase image definition.

Our Readings (with the above settings):

Contrast: >5000:1
Black: <0.03 cd/m²
Gamma: 4.5 / 5
Delta E: 3
Average discrepancy across display: 2%
Viewing angles: 3.9 / 5
Power use: 200 W
Media player: 3.2 / 5

  • Contrast over 5000:1
  • Very wide viewing angles
  • Excellent screen responsiveness (6 ms on average)
  • Accurate colours: average Delta E = 3
  • Excellent 3D mode: practically no crosstalk


  • Glossy screen is prone to reflections
  • High power use: 200 watts


The Panasonic Viera ST50 really has nothing to envy of the higher-end VT50. In fact, image quality is just as good in this model. We therefore don't see much point in shelling out for the pricier model, as the ST50 won't disappoint home cinema buffs.
