The TV is an overall good performer, with some caveats. Incorporating a direct LED backlight instead of LED edge lighting, the black levels were pretty even across the screen. However, with Smart Dimming engaged, the black level, although deeper, sometimes gives extremely dark scenes a muddy look and also has the unexpected result of making the TV look like it is momentarily turned off during certain transitions, such as between the end of a movie and the beginning of the ending credits.
On the other hand, I found that color saturation, detail, and contrast range were all very good with high definition source material, especially Blu-ray Discs, but E420i doesn't quite have the richness you would see on a higher-end (and, of course, higher-priced) set. Also, I didn't think that the E420i faired as well with standard definition sources, such as analog cable and internet streaming content.
When I conducted a series of tests to find out how well the E420i processes and scales standard definition source content, the E420i only did a fair job extracting detail and suppressing video noise, and also had some difficulty recognizing differing film and video frame cadences.
However, the E420i did a good job minimizing deinterlacing and motion artifacts, and exhibited an overall smooth motion response, considering that its "120Hz" refresh rate is obtained via blacklight scanning in combination with an actual 60Hz true screen refresh rate.

Another interesting thing about the E420i is that, for a budget priced TV, provides a lot a picture adjustment options that include both basic presents and additional custom settings (see menu example).
However, to take advantage of the TV's setting options, it is advisable to at least use a calibration test disc, such as DVE HD Basics Blu-ray Edition, or the THX Optimizer, which can be found as a supplementary feature on any THX Certified Blu-ray Disc movie release, or the new THX Tune-Up App for iPhone/iPad.
StudioSound creates as wider sound field, which improves the depth and spaciousness of the reproduced by the TV's speakers, while TruVolume compensates for level changes within a program or when changing between sources, but the actual sound quality (especially the lack of any real bass) of the E420i is much like the sound quality from most TVs I have reviewed.
