This tv was replaced by the Vizio D Series 4k 2018

Type : LED
Resolution : 4k
Refresh Rate : 60 Hz

The Vizio D Series 4k UHD LED TV is a good budget TV that delivers better than average picture quality. Its aesthetic won't win anyone over, but it handles motion very well and is very responsive. It lacks some of the features found on higher end TVs but performs quite well - as long as it is viewed from directly in front. In a room setup where you will be viewing the TV from the side, the Vizio D loses a lot of its appeal. Note: this review is for the 4k UHD variant of the D Series. We reviewed the 1080p version separately here.

Vizio D Series 4k 2016 Design Picture
Curved : No

The Vizio D Series 4k won't impress with its looks or thinness. In fact, it might remind you of the look of old LCD TVs, minus the very large borders. Before you buy, make sure you have a table that is broad enough to accommodate the wide stand.

Stand
Vizio D Series 4k 2016 Stand Picture

When using the stand, the TV leans a little bit toward the back.
Footprint of the 50" TV stand: 10" x 39.2"

Back

Wall Mount : VESA 200x200

Although the TV is thick, its back connections are arranged so there are no wires that can stick out from the back. It can then be mounted flush on a wall.

The TV is quite thick, with no real thin parts.

7.2

Picture Quality

Score components:

The Vizio D 4k 2016 delivers above average picture quality. Even in a totally dark room, dark scenes look great and uniform. Unfortunately, the picture is a little soft when watching DVDs and cable TV. It lacks many of the features found on higher end TVs such as local dimming. Unfortunately it doesn't get very bright and the picture quality diminishes when viewed from the side.

8.5 Contrast
What it is: Brightness difference between white and black. This is the main component of picture quality.
When it matters: Always, but especially when watching dark scenes.
Score components:
Vizio D Series 4k 2016 Checkerboard Picture
Native Contrast
What it is: Ratio of the white brightness divided by the blacks measured on our checkerboard test pattern with a white target of 100 cd/m².
When it matters: Dark scenes in a dark room.
Good value: > 3,000
Noticeable difference: 500
:
4356 : 1

The deep blacks the Vizio D has make for a high contrast ratio and good picture quality.

2.0 Local Dimming
What it is: The lights behind the LCD layer adapt to the picture displayed, improving the contrast ratio.
When it matters: Dark scenes viewed in a dark room.
Score components: Subjectively assigned
Local Dimming
What it is: Whether it has a feature that controls the LEDs behind the LCD layer, to match the picture and darkens the dark portion of it.
When it matters: On LED TVs only. Dark scenes viewed in a dark room.
:
Yes
Backlight
What it is: Configuration of the lights of the backlight.
When it matters: Effectiveness of the local dimming.
Good value: Full-array/direct lighting is better for local dimming. As for the uniformity of the screen, it depends on the implementation. Some edge-lit TVs have more uniform blacks than some full-array TVs.
:
Full-Array

Local dimming really didn't work well on this TV, even though it has a full-array backlight. You don't see any blooming, even though the zones are really big, because the overall picture darkens too much.

Motion

The Vizio D Series 4k LED is a good TV for content with fast motion. It is able to produce clear picture even when there is very fast movement. Movies play smoothly via a blu-ray player or with the in-built apps. It is a 60Hz panel and so can only interpolate 30Hz content.

8.8 Motion Blur

The response time is good and the result is clear fast motion. The trail following the moving logo in our test is short. The down transitions are a bit slower than the up transitions, which results in an orange tone between the letters of our logo.

The Vizio D Series 4k uses PWM to dim the backlight, which can be seen in duplications following the motion blur logo. It is possible to reduce this frequency to 60Hz to clear up motion.

7.1 24p Playback
What it is: Whether 24p content can play without any judder.
When it matters: Only 24p content (mostly just movies).

This TV isn't able to completely remove judder. 'Reduce Judder' does reduce the amount of judder on 24p content, but still couldn't remove it completely.
Update: Enabling 'Game Low Latency' solved the 24p issue, but still not over 60p or 60i.

Vizio advertise this TV as a '120Hz Effective Refresh Rate' which is more of a marketing term. The Vizio D 4k 2016 is in fact a 60Hz TV and as such, can only interpolate content with a refresh rate of 30Hz and lower, using the 'Reduce Judder' setting. Cable TV and streaming services that run at 60Hz won't be able to use the soap opera effect.

This is the lowest input lag we have measured on a TV so far. The time it takes for the TV to respond to a controller input is extremely low. Any serious gamers, even those playing competitively, should be pleased with the Vizio D. To get the input lag to a minimum, we had to use the 'Game' picture mode and the HDMI 5 input. For the HDMI 1, the 1080p input lag under game mode (with 'Game Low Latency' on) is 42.2ms.

Sound Quality

Score components:

The Vizio D Series UHD TV doesn't get very loud. It is also lacking in terms of bass. Overall, it does a decent job, but you will definitely need to buy an external sound system if you care about sound.

Note: Sound Quality test for TVs reviewed before 2017 was performed at 75dB, 85dB, and Max SPL. Starting 2017, the target SPL levels have been changed to 70dB, 80dB, and Max dB SPL.

High distortion. Even though the TV doesn't get loud (barely reaching 85dB SPL), the distortion level is quite high. It should also be noted that the plasticky frame of the TV shakes and rattles quite noticeably under loud and full-range content.

Differences between Sizes and Variants

The Vizio D Series 4K TV that we bought is the 50" with SKU D50u-D1. We expect our review to be valid for the 40" (D40u-D1), 55" (D55u-D1), 58" (D58u-D3) and 65" (D65u-D2). It is not valid for the 1080p variations of the Vizio D Series which we reviewed separately here.

If someone comes across a different type of panel or if their Vizio D Series doesn't correspond to our review, let us know and we will update the review.

Compared to other TVs

Bottom right: Vizio D Series 1080p 2016 (D50-D1).  Unlike our other photographs, this picture wasn't taken under a controlled environment, so do not draw conclusions from it.

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. 

Vizio E Series 4k 2016
43" 48" 50" 55" 55" 60" 65" 70"

The Vizio E Series 4k 2016 we reviewed has similar performance for watching movies, however doesn't perform as well for sports and video games due to the higher motion blur and input lag. If you're choosing between these two then go with the Vizio D Series 4k 2016.

Samsung KU6300
40" 43" 50" 55" 60" 65" 70"

The Samsung KU6300 is a bit more pricey, but can achieve a brighter image especially with highlights. For video games however, the Vizio D Series 4k 2016 series is a clear winner and the picture quality of the Samsung  KU6300 isn't enough of an improvement to justify the higher price.

TCL US5800
55" 65"

Although the TCL US5800 lacks some features such as local dimming and motion interpolation, the Roku smart interface is more intuitive and feature-packed. For movies and TV the picture quality is quite similar, however gamers should stick to the Vizio D Series 4k 2016 for the lower input lag and motion blur.

Vizio D Series 1080p 2016
32" 40" 43" 43" 48" 50" 55" 60" 65" 70"

The Vizio D Series 1080p 2016 performs very similarly to the 4k model, just with a lower resolution panel. It has slightly higher input lag so more serious gamers may prefer the Vizio D Series 4k 2016. For those that don't watch 4k content or use the TV as a PC monitor, the Vizio D Series 1080p 2016 provides the same experience at a lower price, with a huge range of TV sizes to choose from.
