Value Comparison Summary


Depsite the difference in price tag, there really isn't a whole lot different between these two TV sets aside from two major tradeoffs: the Sony has great picture quality but few connectivity options, and the LG has almost double the viewing angle of the Sony. Really, unless you absolutely need the one extra inch of screen space, or can find the LG for cheaper, the Sony will probably be a better buy than the LG 47LD4500.

Blacks & Whites


The Sony KDL-46BX420 is a hard act to follow in terms of black and white performance, and the LG's awful black level hurts not only its contrast ratio, but its overall score, despite its unusually high peak brightness.
