This tv was replaced by the Vizio M Series 2015

The Vizio M Series LED TV is great, but depending on the size and your usage, you might prefer to get the cheaper E Series instead.

  • Great viewing angle. The colors stay the same even when viewed from the side (depends on size; see the Q&A section for details).
  • Low amount of reflection. The picture quality in bright rooms is great.
  • Low contrast ratio. In a dark room, the blacks are gray (depends on size; see the Q&A section for details).
  • Better gray uniformity than the E Series, but it still has some issues.
  • The full array local dimming feature works better than the E Series, but we don't recommend using it (see the Q&A section for details).

Vizio M Series Design

The design of the M Series is less bland than on the E Series. It is thinner, and the frame has a brushed metal finish.

Vizio M Series Stand

The stand feels flimsy. The TV moves a lot when you push it.

6.7 Contrast
Vizio M Series Contrast
Black : 0.090 cd/m2
White : 102.4 cd/m2
Contrast : 1138 : 1

The Vizio M552i-B2 that we tested had a low contrast ratio. If you have a dark room with only one light turned on, the black color will appear grayish. This depends on the size. See the Q&A section for details.

7.5 Black Uniformity
Vizio M Series Black Uniformity

The bottom right corner of the screen is noticeably brighter than the rest. Aside from this, there are no clouding issues.

5.5 Gray Uniformity
Vizio M Series Gray Uniformity

The gray uniformity of the M series is an improvement over the E Series. You can no longer see the individual LEDs behind the LCD layer. However, narrow darker bands create a dirty screen effect on panning shots.

7.8 Viewing Angle
Viewing Angle : 37 °

Our unit had an excellent viewing angle. The saturation of the colors stays great. This also depends on the size. See the Q&A section for details.

9.0 Average Room

Reflection : 1.8 %

It has a semi-gloss finish, but it does a good job of keeping the reflection under control.

The Vizio M Series LED TV can get very bright, almost more than any other TV that we tested.

The motion blur is average-good for an LED. Contrary to the E series, the 'Motion Blur Reduction' feature does not reduce the blur (see the Q&A section for details).

The Vizio M Series has better uniformity than the cheaper E Series and more effective local dimming, too. It also adds the motion interpolation feature. However, depending on the size, it might have a significantly lower contrast ratio (but better viewing angle). If you don't plan on using either the motion interpolation or the local dimming, get the cheaper E Series instead.
