Vizio M320NV LCD HDTV Review

32 in.

The Vizio E320VL is an entry-level TV that lacks features but put up some good numbers on a lot of our tests.

Motion Performance

Motion Smoothness (8.00)

We didn't see much motion blurring on the Vizio M320NV. We saw some very fine details getting smudged, such as eyes, or fine patterns, but otherwise the picture remained crisp. The TV also has some motion processing, which helps reduce the minimal amount of blur, but will make your movies look overprocessed.

Motion Artifacting (7.25)

We didn't see much in the way of motion artifacting either. There was some slight shudder as static images moved around the screen, which gets slightly worse if the image being displayed is a fine pattern. Otherwise, however, the TV didn't have any issues here. We did notice turning the motion processing up created slightly more artifacting issues, such as ghost images or, in some cases, created a minor flashing effect.

We also ran the motion tests with Smart Dimming enabled. It can create some problems, especially with the the rigorous test patterns we run. The issue with this and all local dimming features is that there are simply too few zones (the areas of the screen that have their own dimming). If a bright object crosses a black background, the objects takes on a wide, diffused halo because the blacks that occupy that same zone are getting brighter, as well. It presents a real problem with movies set in outer space, or during credit sequences, or in any scenes of high contrast. More on how we test motion performance.

3:2 Pulldown & 24fps

Just set Film Mode to Auto and you won't see any issues with the M320NV's 3:2 pulldown or 24fps playback. More on how we test 3:2 pulldown and 24fps.

Resolution Scaling

The Vizio M320NV has a native 1080p resolution, but unless you're exclusively watching Blu-ray discs, your TV will have to display nonnative content. The TV has no problem with 480p and 720p content, but it definitely had a problem with 1080i. Many fine patterns appeared green or yellow in 1080i. Some flashed for a few seconds when they came on screen. What's interesting is we saw these same issues with native content too. Typically these sorts of errors are due to problems with the processing used to upscale or downscale content—it's rare to see a 1080p HDTV have trouble with 1080p content.

These issues were also present in the TV's native 1080p resolution. More on how we test resolution scaling.

480p

There was a small percentage of forced overscan on 480p content, but no issues otherwise. Images looked sharp and we didn't see any artifacts caused by the scaling.

720p

The TV did a great job with 720p overall. We saw some brief, faint flashing and some very minor discoloration in fine patterns, but that was it. Images were otherwise sharp and there wasn't any overscanning.

1080i

The TV fell off a cliff here. Fine patterns showed some pretty significant discoloration, acquiring either a green or yellow hue.
