Our Verdict
Good TV for mixed usage. Picture quality is above average, and motion is handled very well. Very low input lag which is great. Unfortunately the picture diminishes from the side and it lacks features found on high end TVs.
- Excellent TV for gaming
- Great value 4k TV
- Very narrow viewing angle
- Cable and DVDs look blurry
- Poor screen uniformity
Performs well for movies. Displays deep blacks and has good black uniformity for dark rooms. Has local dimming but it doesn't work very well.
Average for TV shows. Upscaled content looks okay, and doesn't have the brightness to compete with reflections in a bright living room.
Average sports performance. Picture quality is above average but screen is not very uniform which results in dirty screen effect. Handles motion very well though.
Very good for video games. Picture quality is above average, and motion handling is great. Fast camera movements handled easily. Exceptional input lag which is great.
Doesn't support HDR. Color gamut only enough for SDR content. Can't get very bright for highlights. Above average picture quality though.
Average PC monitor. Picture quality is above average and handles motion very well. Input lag is exceptional, unfortunately doesn't support a wide range of input resolutions.

The Vizio D Series 4k 2016 performs quite well across the board and excels in gaming performance for those after a 4k TV on a budget. For those that don't require a 4k TV, it is very similar to the Vizio D Series 1080p 2016 which is available at a lower 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 use 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.
