Value Comparison Summary


Even though the TC-L42E30 has a higher price tag, you aren't paying extra for nothing: the smaller Panasonic carries quite a connectivity punch when it comes to internet content, where the KDL-46BX420 has none. If you don't care so much about that, the Sony brings a bigger (in every dimension) screen and vastly better picture quality.

Neither TV impressed in the motion category, and scored extremely closely to each other.

Viewing Effects


Don't believe this chart about the Panasonic TC-L42E30's "good" viewing angle for a minute. While it may appear that it has a wide viewing angle, it only recorded one at a very precise vertical angle that is smaller than most human eyes. We found that if you view the screen from even a couple degrees off-center vertically, the contrast ratio would drop below 50% of maximum, and the necessary positions in a room to take advantage of the theoretically large viewing angle are almost impossible to attain. Conversely, vertical viewing angle doesn't matter so much with the Sony KDL-46BX420, so what you see is what you get.
