Our Verdict
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.
- 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).
Check Price
We buy and test dozens of TVs yearly, taking an objective, data-driven approach to deliver results you can trust. Our testing process is complex, with hundreds of individual tests that take over a week to complete. Most of our tests are done with specially designed test patterns that mimic real content, but we also use the same sources you have at home to ensure our results match the real-world experience. We use two main tools for our testing: a Colorimetry Research CR-100 colorimeter and a CR-250 spectroradiometer.
Test Results
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.
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.
The bottom right corner of the screen is noticeably brighter than the rest. Aside from this, there are no clouding issues.
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.
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.
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 input lag is average-good. To achieve this number, make sure that you start off with either Game or Computer mode (which will get renamed to Custom X when you change one of the values). Otherwise, the input lag is 133 ms.
The smart features are limited. There is no web browser. The app store is powered by Yahoo.
The remote is more advanced than the one available on the E Series. There is a full QWERTY keyboard on the back of the remote.
