Other models in series

Most TVs are part of a series that share similar equipment and performance, but vary in screen size. In the Sony's case, this is the HX929 series with the "55" indicating the size in inches.

TVs within the same series will often perform very similar, sharing much of the same internal circuitry. The "glass" itself, or what makes the actual image, will be different across different TV sizes, but it will usually be of the same "family." In other words, the 46HX929 will likely perform close enough to the 55HX929 that the review of the latter will be a solid indicator of how the 46-inch will look. For more info, check here.
