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.

6.0

Design

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

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.

Borders
Borders : 0.55" (1.4 cm)

Thickness
Max Thickness : 2.48" (6.3 cm)

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

7.2

Picture Quality

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
Native Contrast
:
4356 : 1

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

2.0 Local Dimming

:
Yes
Backlight
:
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.

The SDR peak brightness was tested with local dimming on, and this has the effect of reducing the peak brightness on the smaller sized windows. Turn off the local dimming if you want to have the same brightness on all window sizes.

Like most LED TVs, the uniformity of the screen isn't good and dark patches can be seen whenever the camera pans over playing surfaces like ice or grass. The small number of LEDs in the full-array backlight doesn't help here.

If you don't sit directly in front of the TV, colors appear washed out and black appears grayish. If you sit too close to the TV, even the right and left edges will appear whitish.

Our black pattern is free from any obvious clouding or light bleed, which is great.

The Vizio D Series uses an 8-bit panel. We could clearly see the 8-bit gradation in our gradient pattern, even when the TV was fed with a 10-bit signal.

White balance was good out of the box. Color was ok.

White balance could be fixed correctly with calibration, but we couldn't get individual colors much better without applying extreme values that worsened other colors.

7.0 480p Input

The Vizio D displays 480p softer than most other TVs do. Increasing Sharpness to 20 and activating the 'Reduce Noise' setting fixed most of this problem. It looks softer than even the 1080p equivalent of the D Series (see review).

7.0 720p Input

As with 480p, 720p resolution looks a little blurry. Setting 'Sharpness' to 20 and enabling the 'Reduce Noise' feature can help a little bit.

9.0 1080p Input

Blu-rays looks great on on the Vizio D 4k 2016.

10 4k Input

The Vizio D that we reviewed can display 4k resolution (some other Vizio Ds can do a maximum of 1080p, see our separate review for them)

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
Response Time
:
12.3 ms
Overshoot
:
0.9 ms

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.

6.8 Image Flicker
PWM Dimming Frequency
:
120 Hz
BFI
:
Yes
BFI Frequency
:
60 Hz
BFI In Game Mode
:
Yes

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
Judder-free 24p
:
Yes
Judder-free 24p via 60p
:
No
Judder-free 24p via 60i
:
No

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.

5.0 Motion Interpolation
Motion Interpolation (30 fps)
:
Yes
Motion Interpolation (60 fps)
:
No

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.

You can read more about fake refresh rate here.

8.3

Inputs

The Vizio D Series 4k has exceptional input lag. Unfortunately if it supported more resolutions and frame rates as inputs, it would get a better result. It has a variety of inputs though which should be enough for most people.

9.4 Input Lag
1080p @ 60Hz

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

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.

6.9 Frequency Response
Std. Dev. @ 70
:
2.74 dB SPL
Std. Dev. @ 80
:
2.89 dB SPL
Std. Dev. @ Max
:
3.34 dB SPL
Max
:
85 dB SPL
Low-end Cutoff
:
151 Hz

Poor low-end cutoff and low maximum loudness. The frequency response (tonal balance), however, is decent. The major issue here is the total lack of bass.

5.4 Total Harmonic Distortion
Distortion @ 70
:
0.036
Distortion @ 80
:
0.108
Distortion @ Max
:
0.144

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.

Smart Features

Smart OS : Basic

The smart features of the Vizio D Series aren't that advanced, but cover the basics. Although functional, there is no fancy remote that comes with the TV, either. There is a good number of inputs, though.

Apps

Most popular apps are available, including Netflix, Amazon Video, and YouTube. HBO Go is missing, and there is no web browser.

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

Top left: Vizio E Series 4k 2016 (E48u-D0). Bottom left: Samsung KU6300 (UN55KU6300). Middle: Vizio D 4k (D50u-D1). Top right: TCL US5800 (55US5800). 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. 

Conclusion

7.3 Mixed Usage
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.
7.2 Movies
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.
7.0 TV Shows
Average for TV shows. Upscaled content looks okay, and doesn't have the brightness to compete with reflections in a bright living room.
7.3 Sports
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.
8.4 Video Games
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.
6.6 HDR Movies
Doesn't support HDR. Color gamut only enough for SDR content. Can't get very bright for highlights. Above average picture quality though.
5.3 PC Monitor
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.
