Value Comparison Summary


The Vizio E321VL is a much more appropriately-sized 720p TV, even if the screen size is probably disappointing in comparison to the mammoth 51 inch screen of the Samsung. In reality, you're getting a picture with the same exact resolution, and it will look much better on the smaller, much cheaper Vizio than it does on the Samsung. Really, the only major objective advantage the Samsung has over the Vizio is viewing angle, as plasma screens tend to blow LCD screens away in this metric.

Blacks & Whites


Simply because the Vizio E321VL is an LCD screen, we expected it to perform at a significantly worse level than the plasma comparison models, but it's scoring is bad even for LCD screens. The PN51D450 is the hands-down winner in this one

Viewing Effects


Due to the nature of the differing screen technologies, you can expect the Vizio E321VL to have a much smaller viewing angle, as this is common with LCD screens. The PN51D450, being a plasma screen, has a comparatively massive viewing angle, and is a better choice if this metric is among your chief buying criteria.

Both TVs have a similar amount of ports and no internet connectivity, so you really can't go wrong with either in this regard. There's no major upside to either over the other.
