This TV was replaced by the Vizio V Series 2019

The Vizio D Series 2018 is a decent but basic 4k TV. The picture quality is okay, but the TV lacks more advanced features like local dimming or a wide color gamut to produce deeper dark scenes or vivid HDR. The response time is fast which is excellent for displaying sports without much blur and the TV has low input lag for gaming.

Our Verdict

7.0 Mixed Usage

The performance of the Vizio D65-F1 for mixed usage is okay. Movie and regular cable TV watching is decent, whereas playing video games and using it as a PC monitor should keep you satisfied. This TV does not have a great HDR performance since it has a limited color gamut and will not display rich and saturated colors, far from what the content creator intended.

Pros
  • Deep and uniform dark scenes
  • Fast response time
  • Low input lag
Cons
  • Image degrades at an angle
  • Mediocre HDR
6.8 Movies

This TV is decent for watching movies. It has a very good contrast ratio that will display good blacks in dim environments but lacks any local dimming to further boost blacks. You should not observe much clouding in darker scenes since the TV's black uniformity is very good. Watching 4k and Blu-ray content looks great.

7.3 TV Shows

Watching TV shown on the Vizio D Series 2018 is ok. The TV can get good enough brightness levels for brighter rooms and can handle reflections well. Unfortunately, viewing angles are not very good and thus the picture quality will not be the same if you are watching a TV show while moving around doing some housework. On the other hand, upscaling 720p cable content is ok.

7.0 Sports

This TV is decent for watching sports. The good reflection handling and the great response time. make it a good choice for watching fast action sports in a room with a few lights. Some dirty screen effect is present and that will disappoint sports fans. Also if you plan to watch a game with a big group you take into account that the bad viewing angles do not favor wide seating arrangements.

7.2 Video Games

The Vizio D Series 65 is very good for playing video games. It has a low input lag both in SDR and HDR content, which makes it very responsive to user input, and also has a remarkably fast response time which is great for fast action.

6.5 HDR Movies

Ordinary performance for this TV on HDR movies. Apart from the great contrast and the great 4k content display, this TV is producing a satisfactory result for HDR movie watching. This is mainly because it cannot display rich and saturated colors due to its limited color gamut.

6.8 HDR Gaming

Playing HDR games on this TV is good as it supports the 4k @ 60Hz + HDR input. Also, the fast response time makes it suitable for fast action. The good contrast will offer a decent experience in dark scene HDR gaming. However, you should keep in mind the limited color gamut which will not allow it to display rich and vivid colors.

7.3 PC Monitor

This Vizio D Series will perform very well as a PC monitor mainly due to its remarkable input capabilities. The various supported resolutions and the low input lag should keep most people happy. Also, the fact that there is practically no permanent burn-in risk and no temporary image retention, should not deter you from using it as a PC monitor.

Differences Between Sizes And Variants

The Vizio D Series TV that we bought is the 65" with SKU D65-F1. Different sizes may have different panel provenances, so if your  Vizio D Series 4k 2018 doesn't correspond to our review, let us know and we will update the review.  Note that the gray uniformity does vary between units.

65" D65-F1 D Series 65 120 Hz 60 Hz
70" D70-F3 D Series 70 120 Hz 60 Hz

Note: The D43-F1 variant comes equipped with 8-watt speakers whereas all the others come with 10-watt speakers.

Update 12/12/2018: Vizio has released the V505-G9, which appears to be a variant of the D Series 2018. It is only available in 50", and as far as we can tell, the only difference is the addition of Dolby Vision support, and possibly an adjustable BFI mode to reduce persistence blur. There may be other differences that we are not aware of.

Compared To Other TVs

Bottom right: Samsung NU7100 (UN55NU7100FXZA ).  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 2018 is a good low-mid-range 4k TV with a few minor flaws. See our recommendations for the best cheap TVs.

Samsung NU6900
43" 50" 55" 65" 75"

The Vizio D Series 4k 2018 and the Samsung NU6900 are both decent TVs, but the Vizio is marginally better for some uses. The Vizio can get slightly brighter, but the Samsung has better gray and black uniformity, as well as slightly more accurate colors out-of-the-box. The Vizio is quite a bit better with motion handling overall, but the Samsung has better built-in speakers.

Samsung NU7100
40" 43" 50" 55" 58" 65" 75"

The Samsung NU7100 and the Vizio D Series 4k 2018 have very similar performance. The Vizio D Series 4k 2018 has a faster response time which is great for fast action. It can get slightly brighter and can handle reflections better which is great for watching TV shows. The Samsung NU7100, on the other hand, has lower input lag for gaming and better motion interpolation for those who like the soap opera effect. It also has slightly better 720p upscaling that is better if you watch a lot of cable TV.

LG UK6300
43" 49" 50" 55" 65"

These two TVs have different panel types, each with its advantages and disadvantages. If you've got a room with wide seating arrangement, then the LG UK6300 is a better choice thanks to the wide viewing angles of its IPS panel. If you're sitting directly in front of the TV, then the Vizio D Series 4k 2018 is a better choice as it can deliver deeper and more uniform blacks in a dark room and can get brighter to fight glare in a bright room. The LG UK6300, on the other hand, has better reflection handling and has an optional motion interpolation feature to please the Soap Opera Effect fans.

TCL 5 Series 2018
43" 49" 55" 65"

The TCL 5 Series S517 and the Vizio D Series 4k 2018 have very similar performance. The Vizio D Series 4k 2018 has better reflection handling and better response time that make it a better choice for sports watching, whereas the TCL S517 is better for movies since it supports motion interpolation. The TCL also has lower input lag which makes it more responsive, and this is important when gaming.

Vizio E Series 2018
43" 50" 55" 65" 70" 75"

The Vizio E Series 2018 is a bit better than the Vizio D Series 4k 2018. The Vizio E Series has a local dimming feature, although it isn't very effective. The E series has an optional Black Frame Insertion feature that can help clear up motion. The E series also supports Dolby Vision, which doesn't add much but is a nice extra. The Vizio D Series 4k 2018 has wider viewing angles, good if you have a large seating area.

Hisense H9E Plus
55" 65"

The Hisense H9E Plus is a bit better than the Vizio D Series 4k 2018. The H9E Plus features a wide color gamut, great for HDR, and has much better motion processing as it can interpolate content as high as 120 fps and can remove judder from all sources. The Vizio D is better for use as a PC monitor, as it displays chroma 4:4:4 without issue.

Vizio V Series 2019
40" 43" 43" 50" 55" 55" 60" 65" 65" 70" 75"

The Vizio D Series 4k 2018 and the Vizio V Series 2019 both have very similar performance. The Vizio V Series 2019 has a marginally higher contrast ratio that delivers deeper and more uniform blacks, which is great for watching movies in a dark room. The Vizio D Series 4k 2018 is marginally brighter and has a slightly better response time that produces crisper motion.

Test Results

Design
Style
Curved No

The design of the Vizio D Series 65 is ok. It has a wide and quite stable stand, although it wobbles a little if slightly pushed. The back is plastic and the TV seems relatively thick when you are looking at it from the side. The build quality is ok and it should not cause any issues. Overall, the TV looks very similar to the Vizio E Series 2018, but the D Series lacks a metal trim.

Design
Stand

The stand of the Vizio D Series 4k 2018 is plastic and provides good support to the TV. However, the TV will wobble slightly back and forth if pushed gently.

Footprint of the 55" model: 50.6" x 10.6"

Design
Back
Wall Mount VESA 400x200

The back of the TV is plastic. It has a more sleek look and the inputs are still split between the side and the bottom edge, which makes them easier to access if you wall mount the TV. There is no planning for cable management.

Design
Borders
Borders 0.83" (2.1 cm)

The borders are simple. They have a textured plastic finish and average thickness. They  look identical to E series 2018 but they lack the silver trim on the bottom edge.

Design

Max Thickness 3.35" (8.5 cm)

The TV looks a little thick and blocky when viewed from the side, so it may stick out slightly if wall-mounted. Like all other Vizio models we tested this year, the structure of the TV (screen and electronics' compartment) is more apparent when the TV is viewed from the side.

The Vizio D series 4k 2018 has ok HDR peak brightness. It does not get very bright to display bright highlights as the creator intends, but it does not dim highlights and it displays a steady brightness no-matter the window size.

If you find HDR content too dim, raising the Backlight setting to 100 (rather than the default 50) and setting the Gamma to 1.8 will brighten most HDR shades, but unfortunately won't affect peak highlights.

Also during our testing the TV got stuck once at 70 cd/m², but resetting the picture mode fixed the issue.

The gray uniformity is decent. On the 50% gray uniformity test picture, we can see that the four corners are a slightly darker than the center. Some clouding is apparent which causes a little dirty screen effect which might annoy some people when viewing sports.

On the 5% gray uniformity picture, things are a little better as not much clouding can be noticed.

The viewing angle is bad for this Vizio D Series 2018. Blacks fade to grey at only small angles off the center and colors shift rapidly at an angle as well. It is not a great choice if you plan on placing it in a wide room.

The TV has very good out of the box color accuracy. When set to Calibrated Dark, the color dE and white Balance dE are well below 3, so most people will not notice any inaccuracies.

The gamma is at 2.19 almost right on our 2.2 target. Finally, the color temperature is close to 6500K resulting in a fairly accurate picture.

The post calibration picture is close to perfect. The calibration process is fairly straightforward and relatively fast to do. The white balance dE was brought down to 0.08.

The color gamut is decent, but the TV fails to be classified as having a wide color gamut since the cover of the Rec 2020 uv space fails to surpass our target of 67%.

The HDR EOTF in the Calibrated Dark picture mode follows the target PQ curve well at first, but then begins its roll-off really early, so well-lit areas of HDR scenes will be shown less bright than intended. If you find HDR content too dark, raising the Backlight setting to 100 and setting Gamma to 1.8 will raise the EOTF and brighten most HDR scenes.

Enabling Game Low Latency doesn't change the EOTF, which is good, and the EOTF in the Computer picture mode is also very similar.

The color volume on this Vizio D Series 65 is mediocre. The inability of the TV to display a full range of colors across a range of brightnesses esteems from the limited color gamut. Colors on this TV will not be very rich and darker color shades will be crushed.

The TV uses PWM to dim its backlight, so the backlight flickers at all Backlight settings below 100. The flicker frequency is at 480 Hz, which is high so it isn't very noticeable except in small duplications behind moving objects.

Also we noticed that the backlight also dips down at every 1/60th of a second (60Hz) as shown in in the backlight@100% plot. This should not be noticeable to most and should not worry you.

The input lag is very low. To achieve low input lag you must set the Game Low Latency to on, You can do that from any picture mode so we recommend using the Calibrated Dark picture mode.

4:4:4 is only shown properly in the Computer picture mode and the Game Low Latency must be enabled for low input lag. It is however enabled by default when a 4:4:4 signal is sent and thus it is grayed out.

The frequency response is sub-par. LFE (low-frequency extension) is at 170Hz, which is inadequate. This means that the bass of this TV won't have any thump or rumble, and will lack quite a bit of punch too. The response above the TV's LFE is also sub-par as the underemphasis in the treble range will negatively affect the intelligibility of dialogue. Additionally, this TV get doesn't get very loud, and doesn't have a room correction system.

The distortion performance is mediocre. The overall amount of produced THD is elevated, which tends to make the sound impure. But there is not a big jump in THD under maximum load, which is good. However, this TV doesn't get very loud.

The interface is slow and basic, with no animations. There is noticeable lag when browsing the TV shows and movies tabs. (in our test after 3 pictures the TV was stalling for a short period of time before becoming fluid again).

Also during our HDR testing, the TV got stuck once at a really dim 70 cd/m², but resetting the picture mode fixed the issue.

Remote App Vizio SmartCast Mobile

Very basic and lightweight remote, same as Vizio E Series 2018 and M Series 2018. Small buttons, hard to read for some, but intuitive layout and easy to use. There are 6 button shortcuts for various streaming services at the top of the remote.

There is no voice control built into the remote or on the TV, but if you have a separate Google Home or Amazon Alexa device they can interface with and control the TV.
