Vizio M320NV LCD HDTV Review
The Vizio E320VL is an entry-level TV that lacks features but put up some good numbers on a lot of our tests.
The Vizio M320NV is a 1080p HDTV, although it had some issues displaying native content.
The M320NV had a decent viewing angle for an LCD, but its performance still pales in comparison to the average plasma. Once you get about 38° away from front and center, you'll only see about half of the TV's maximum contrast ratio. As you can see in the graph below, the M320NV had a better viewing angle than many competing LCDs.
External light will create a large diffuse glow on the M320NV's screen, assuming the light is shining directly at the screen. If the light is shining at the screen from an angle, it'll catch the bezel but otherwise won't bother you.
The Vizio M320NV has a whole list of processing features, most of which actually work as described. The main feature here is the Smart Dimming feature, which is Vizio's brand of local dimming. Local dimming means the screen is basically separated into different zones that can dim independently. While this allows for some deep blacks, there's a few downsides as well. Since there are only a handful of zones, when one lights up to illuminate a bright object, it also brightens the blacks in that area. For example, as a rocket flies through empty space, the black around the rocket will be noticeably brighter than the surrounding space.
None of the other functions are as exciting as the Smart Dimming feature and all have minor or detrimental affects. Also note that we've faithfully copied the function descriptions directly from the tooltips on your TV: the inconsistent capitalization, punctuation, and grammar are all courtesy of Vizio.
