When using the stand up, the TV leans a little bit toward the back.

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

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 water ice or grass. The pocket-size number of LEDs in the total-assortment backlight doesn't assist here.

Our blackness pattern is costless from whatever obvious clouding or light drain, which is great.

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

Colour dE 1.97

Gamma 2.21

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

The Vizio D displays 480p softer than virtually other TVs do. Increasing Sharpness to twenty and activating the 'Reduce Noise' setting fixed most of this problem. It looks softer than fifty-fifty the 1080p equivalent of the D Series (run across review).

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

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

The Vizio D that nosotros reviewed can brandish 4k resolution (some other Vizio Ds tin do a maximum of 1080p, meet our divide review for them)

Motion

Response Time 12.3 ms

Overshoot 0.9 ms

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

BFI Yes

BFI Frequency 60 Hz

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

Judder-free 24p Yes

Judder-free 24p via 60p No

Judder-gratis 24p via 60i No

This Television receiver isn't able to completely remove judder. 'Reduce Judder' does reduce the corporeality of judder on 24p content, but still couldn't remove information technology completely.
Update: Enabling 'Game Depression Latency' solved the 24p issue, but nonetheless not over 60p or 60i.

Motion Interpolation (xxx fps) Yes

Motion Interpolation (60 fps) No

The Vizio D 4k 2016 is in fact a 60Hz Telly and equally such, tin can just 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 issue.

This is the lowest input lag nosotros accept measured on a TV so far. The time it takes for the Television set to respond to a controller input is extremely low. Any serious gamers, fifty-fifty those playing competitively, should be pleased with the Vizio D. To become the input lag to a minimum, we had to employ the 'Game' picture show 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.

Depression-end Cutoff 151 Hz

Poor depression-stop cutoff and low maximum loudness. The frequency response (tonal residue), however, is decent. The major consequence here is the total lack of bass.

Distortion @ 70 0.036

Baloney @ eighty 0.108

Distortion @ Max 0.144

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