The Vizio P Series Quantum X is an excellent 4k LED LCD TV. It delivers great overall picture quality with deep, uniform blacks, outstanding peak brightness, and a great local dimming feature. Motion looks great, thanks to the outstanding response time. It also has excellent low input lag, ensuring a responsive gaming experience, although it doesn't support any of the advanced gaming features, like FreeSync, found on some other TVs. Unfortunately, the image degrades when viewed at an angle, and there is noticeable banding in areas of similar color.

Pros
  • Outstanding peak brightness in SDR and HDR.
  • Deep, uniform blacks.
  • Great motion handling.
Cons
  • Image degrades when viewed at an angle.

Market Context

What it is: This model's position in the TV market; how it compares to other TVs.

The Vizio P Series Quantum X is Vizio's top TV for 2019, and is the direct replacement for the 2018 Vizio P Series Quantum. The main competitors from a performance standpoint are the Samsung Q80R, the Samsung Q90R, and the Sony X950G.

8.5

Design

Score components: Subjectively assigned
Curved : No

The Vizio P Series Quantum X has a great design, and is identical to last year's Vizio P Series Quantum. The stand has a nice metal finish and supports the TV well, but the two feet are nearly the full width of the TV, so you'll need a wide stand if you aren't VESA mounting it. This TV, like last year's, has very good build quality, with no obvious points of concern.

Stand

The stand is slim but well-built, and it supports the TV well. Unfortunately, the feet are very wide and can't be reversed, so you'll need a very wide table if you aren't wall-mounting it.

Footprint of the 65" stand: 50.8" x 11.7".

Back
Wall Mount : VESA 400x400

The back of the TV is plain, made up of a single textured plastic panel. The inputs face down and to the side, and they are easy to access when the TV is VESA mounted.

Unfortunately, there is no cable management.

Borders
Borders : 0.35" (0.9 cm)

The borders are thin and aren't distracting at all when watching TV.

Thickness
Max Thickness : 2.72" (6.9 cm)

The TV is relatively thin and doesn't stand out very much when viewed edge-on. It looks great when wall-mounted, but isn't as thin as OLED TVs like the LG C9.

Temperature
What it is: It is the average and maximum operating temperatures we measured on the TV. If there is an external device, like a One Connect box in some Samsungs, we measure the temperature of that as well.
When it matters: If the temperature of your TV is much higher, check that nothing is blocking the vents.
Maximum Temperature
What it is: The peak temperature found on the TV.
When it matters: If the TV is placed in an enclosed space.
Good value: <35°C
Noticeable difference: 5°C
:
99 °F (37 °C)
Average Temperature
What it is: The average temperature measured on the TV.
When it matters: If the TV is placed in an enclosed space.

This image was taken with a different camera, as our FLIR E8 is currently out for repair. We don't expect this to affect our results.

8.0 Build Quality
What it is: It represents our perception of the quality of the construction of the TV, of the materials used, and how they all blend.
When it matters: Poor build quality might lessen the expected lifetime of the TV, or make it more prone to faults due to mishandling.
Score components: Subjectively assigned

The P Series Quantum X appears to be well-built, with no obvious deficiencies or weak points.

8.2

Picture Quality

The Vizio P Series Quantum X delivers great overall picture quality. It has an outstanding native contrast ratio, and the local dimming feature is great. Like last year's model, this is one of the brightest TVs on the market, and it has the widest Rec. 2020 color gamut we've measured so far. It has great black uniformity, excellent reflection handling, and decent gray uniformity. Unfortunately, like the majority of VA TVs, the image degrades when viewed at an angle. It also has worse-than-average gradient handling, which results in noticeable banding in some content.

9.0 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:
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
:
14743 : 1

The P Series Quantum X has an outstanding native contrast ratio and delivers extremely deep blacks, even with the local dimming feature off. With local dimming enabled, the contrast ratio is one of the best we've ever measured, similar to the 2018 Vizio P Series Quantum and the Samsung Q9FN.

8.0 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

The full array local dimming feature is extremely effective at dimming dark areas on the screen and is one of the best we've ever seen. It reacts quickly to fast scene changes, but can't always keep up, and it tends to dim the outside edges of bright, fast-moving objects, which can be noticeable in some scenes.

There is noticeably less blooming around bright objects than last year's model. There can still be some noticeable blooming around subtitles in dark scenes though, as well as around very bright objects in dark scenes, but it's better than previous models.

If you enjoy local dimming and don't mind some variation in screen brightness or blooming, then set local dimming to 'Medium'. This does increase the overall brightness of the image though, and can result in distracting blooming around bright objects. If you prefer a less aggressive local dimming implementation or find the brightness too high after decreasing the 'Backlight' then set it to 'Low', or disable local dimming completely if you don't like the changes in brightness.

The setting that controls the backlight is known as Active Full Array. During testing, we discovered that adjusting this setting sometimes caused the Black Frame Insertion feature to be disabled.

Note: The 75" model has more dimming zones, and we expect the local dimming feature to perform slightly better.

Update 07/16/2019: Text updated to clarify settings.

The 2019 Vizio P Series Quantum X has outstanding peak brightness in SDR, very close to the Sony Z9F and 2018 Vizio P Series Quantum.

We measured the peak brightness after calibration, with the 'Calibrated Dark' Picture Mode, Local Dimming set to 'Medium', and the Color Temperature set to 'Normal'.

If you prefer a brighter image, or a colder color temperature over an accurate one, with the 'Standard' Picture Mode we measured a peak brightness of 2922 cd/m² for a short period of time, as measured on the 10% test window.

By design, the TV dims when it detects a static pattern, including our test patterns. Vizio sent us instructions on how to work around this, but we were still unable to get consistent results, as the TV's brightness is very finicky.

This TV can get extremely bright in HDR. Small highlights in some scenes are extremely bright, which is great. Even large, bright scenes are very bright, although not quite as bright as last year's model.

We tested the HDR peak brightness with no calibration settings, using the 'Calibrated Dark' Picture Mode, with the Backlight set to '50', and local dimming set to 'Medium'.

If accuracy isn't as important to you, or if you prefer a colder color temperature, the 'Standard' Picture Mode hit a peak brightness of 2741 cd/m² for a short period of time, with the Color Temperature set to 'cool', and local dimming on 'High'.

By design, this TV dims the screen when it detects static images, like our test patterns. Vizio sent us instructions on how to work around this, but we still weren't able to get consistent results.

The P Series Quantum X has a poor viewing angle. Moving off-center, the image loses brightness, and the black level increases, causing the image to appear washed-out. At even moderate angles colors lose accuracy and appear washed-out.

Like the Vizio P Series Quantum, this TV has an optional 'Enhanced Viewing Angle' feature, which is intended to improve viewing angle performance. We measured both and found no advantage for enabling this feature. When it is enabled, it changes the TV's sub-pixel dimming, which reduces the overall color resolution and causes some noticeable issues.

During testing, when changing inputs the Enhanced Viewing Angle function would engage itself automatically, but the setting still shows 'Off'. To disable it, we had to turn it on, then off again.

The P Series Quantum X has an outstanding color gamut, one of the best we've ever measured. It covers almost the entire DCI-P3 color space, and has the best Rec. 2020 coverage of any TV we've tested so far.

Some dark scenes appear too dark, but otherwise this TV follows the PQ EOTF curve well, before tone-mapping near the TV's peak brightness. In 'Game' mode, the EOTF is identical.

If you find HDR too dim, check out our recommended settings here. With these settings, HDR content appears much brighter on the Vizio P Series Quantum X 2019, as shown here.

We don't expect VA panels to experience permanent image retention, as the VA panel in our long-term test appears immune.

Pixels
What it is: The smallest element a screen can display is called a pixel. In color TVs, this consists of three (or more) subpixels. This is a picture of the TV's pixel structure.
When it matters: It can help explain some display behaviors and can provide an indication of whether two panels are the same or not.

The P Series Quantum X uses an inversed BGR sub-pixel layout, which isn't ideal for use as a PC monitor.

When the enhanced viewing angle feature is enabled, some subpixels are partially dimmed, as shown here.

7.9

Motion

The P Series Quantum X 2019 has very good motion handling. It has an excellent response time, but there is some ghosting in some scenes. It also has an optional black frame insertion feature, which can help to improve motion clarity, but we had some issues getting it to work properly. Unfortunately, this model also uses PWM to dim the backlight; this flicker can cause duplications in motion and can bother some people.

9.5 Response Time

Good value: 0 Hz or very high frequencies (> 300 Hz). Frequencies that are multiples of 60Hz are better.
:
120 Hz

Unfortunately, this TV uses PWM to dim the backlight, and there is a 120Hz flicker at all backlight levels other than max. This results in duplications in motion, which might be noticeable in certain content.

Although we initially measured a 960Hz flicker on the 2018 Vizio P Series and Vizio P Series Quantum, which is much less noticeable, we have retested them and found that they also flicker at 120Hz now. We don't know when this change occurred, but it was likely in one of the firmware updates over the past year.

10 Black Frame Insertion (BFI)
What it is: How effective the TV's flickering capabilities are in making motion look clearer, when flicker is desired.
When it matters: When flicker is desired by the user. Flicker is especially useful to make motion look clearer when viewing 60 fps content (sports, video games) and when using motion interpolation.
Optional BFI

When it matters: When playing video games with fast motion.
Good value: 60 Hz
Noticeable difference: 20 Hz
:
60 Hz

For even clearer motion, this TV has an optional black frame insertion(BFI) feature, which reduces the backlight flicker frequency to 60Hz. There was a bug during testing, where adjusting the local dimming feature to a higher setting disabled this feature.

We found the BFI feature to behave very erratically. When enabling this feature, we found that it wouldn't always start flickering at the right time, which resulted in strobe crosstalk duplications. It appears to be random, but enabling Game Low Latency appears to be more likely to get a perfect image.

When BFI is enabled, a compensation algorithm is engaged to try and compensate for the normally reduced brightness. This is why the image appears so different from our usual BFI photos.

10 Motion Interpolation
What it is: Also known as 'Soap Opera Effect'. It is an optional feature that increases the frame rate of the video, smoothing movement.
When it matters: If you like the look of smoothed video. Not everyone does.
Motion Interpolation (30 fps)

The P Series Quantum X supports most common input formats but does not support 1440p. All supported formats can display proper 4:4:4, as long as the Picture Mode is set to 'Computer'. This is especially important when using it as a PC monitor. Some formats require the full bandwidth of HDMI 2.0, and the Full UHD Color setting has to be enabled for the port used.

HDMI port 5 is a low-latency port, and it does not support some formats. HDR is not supported, and although 4k @ 60Hz is supported, it only works at 4:2:0.

Sound Quality

What it is: How well and accurately the audio is reproduced.
When it matters: When a good and accurate sound reproduction is needed.
Score components:

The Vizio P Series Quantum X that we tested has disappointing sound, but something might be wrong with our unit, so your experience may vary. Our unit can't get very loud and has very little bass, with no thump or rumble and very little punch. It delivers clear dialog, though, and there is very little distortion, which is great. Per our out of spec policy, it's up to the manufacturer to decide if this warrants buying a new unit. If you bought this TV, let us know how it sounds in the discussions below.

4.4 Frequency Response
What it is: How accurately the sound level of each frequency is being produced.
When it matters: For a balanced and neutral sound.

What it is: The amount of difference between the TVs frequency response performance at 70dB SPL and Max dB SPL. Too much compression will result in pumping in the sound.
When it matters: When an accurate and free-of-pumping performance is required at higher volumes
Good value: < 3dB
Noticeable difference: 0.5
:
1.42 dB

The frequency response of our unit is bad, but something might be wrong with our unit, so your experience may vary. For reference, last year's P Series Quantum frequency response was average.

Low-frequency extension (LFE) is very high, and this TV has very little bass, with no thump or rumble and very little punch, but it produces well-balanced and clear dialog. Our unit can't get very loud, though, and is not suited for loud environments.

Note that there is an error in our graph due to a bug, which scales the green line up to 80dB. This line should be at the same place as the red and blue lines.

Bottom right: LG SM9500 (65SM9500). Unlike our other photographs, this picture wasn't taken under a controlled environment, so do not draw conclusions from it.

The Vizio P Series Quantum X is an excellent TV for most uses, and it outperforms many pricier models. See our recommendations for the best TVs, the best 4k TVs, the best 4k gaming TVs.

Vizio P Series Quantum
65"

The Vizio P Series Quantum X and the Vizio P Series Quantum are nearly identical. The Quantum X has a slightly wider color gamut. The Quantum X has nearly double the local dimming zones, and although the overall performance is similar, the new model has less noticeable blooming around bright objects. Any other differences between them can larger be attributed to panel variance, and do not necessarily represent a real difference.

Samsung Q90/Q90R QLED
65" 75" 82"

The Samsung Q90/Q90R is a bit better than the Vizio P Series Quantum X. The Q90R has much better viewing angles, and better gradient handling, but slightly worse contrast. The Q90R also has some better gaming features, including support for AMD's FreeSync technology. The Quantum X is a bit brighter in some scenes, and it has a much wider color gamut, although these differences aren't very noticeable. The Q90 has much better smart features as well, including access to a massive selection of apps through the content store.

Sony X950G
55" 65" 75" 85"

The Vizio P Series Quantum X is slightly better than the Sony X950G. The Vizio has slightly better reflection handling, a better black frame insertion feature, and it is brighter. The Vizio also has a much wider color gamut, but the X950G has much better gradient handling. The X950G also has much better smart features and has access to a huge selection of apps through the Google Play Store.

LG C9 OLED
55" 65" 77"

The LG C9 and the Vizio P Series Quantum X use different panel types, each with their own strengths and weaknesses. The C9 is better for a dark room, and it has incredibly wide viewing angles. The C9 also has a nearly-instantaneous response time, outstanding low input lag, and some great future-proof features, like 4 HDMI 2.1 ports. As an OLED TV, the C9 does have a risk of permanent burn-in. The Quantum X, on the other hand, is much brighter, and small highlights in HDR movies look much closer to what the director intended. There is also no chance of burn-in with the Quantum X.

LG SM9500
65"

The LG SM9500 and the Vizio P Series Quantum X use different panel types, each with their own advantages and disadvantages. The Quantum X has a VA panel, which delivers much better dark room performance, with deep, uniform blacks, and it has a great local dimming feature. The LG SM9500, on the other hand, has wide viewing angles, great for wide seating areas, but it doesn't look as good in the dark. On the other hand, the SM9500 is slightly more future-proof, as it supports HDMI 2.1 and has some great gaming features.

8.5 Mixed Usage
What it is: General purpose. The TV will be used for a variety of content and usages. Movies at night, TV shows during the day, video games from time to time, etc.
Score components:
The Vizio P Series Quantum X is an excellent TV for most uses. It looks great in almost any room but has narrow viewing angles, so it isn't as good for watching sports with a group of friends or playing co-op games. Fast movies and games look great, thanks to the fast response time, and games are responsive due to the low input lag.
8.5 Movies
What it is: Movies in the dark. The TV will be used for watching movies in a controlled environment, directly in front, in a home theater way. Mostly only high quality content, like Blu-rays, UHD Blu-rays, streaming and a little bit of HDR.
Score components:
This is an excellent TV for watching movies in a dark room. It has an excellent contrast ratio and a great local dimming feature, so it delivers deep, uniform blacks. Fast-moving action scenes look great, with very little blur, thanks to the fast response time, although this lack of blur does result in a bit more noticeable stutter. This TV also gets extremely bright in both SDR and HDR. Unfortunately, lower resolution movies don't look quite as good, as the 480p upscaling isn't as good as most other TVs.
8.2 TV Shows
What it is: TV Shows in a bright living room. The TV will be used in to watch TV shows, in a bright room during the day, from multiple viewing positions at different angles. The content watched has an average quality: cable, streaming, SD channels, etc.
Score components:
The is a great TV for watching your favorite TV shows during the day. It has excellent reflection handling and can get extremely bright, so glare should never be an issue, even in an extremely bright room. This TV also has a good selection of built-in apps, covering some of the most popular streaming apps, but it isn't possible to add more apps. Unfortunately, due to the poor viewing angle, this TV is best enjoyed from directly in front, so it isn't a great choice if you like to move around with the TV on. Cable content also doesn't look quite as good on this TV, as the 720p upscaling isn't as good as most other brands.
8.2 Sports
What it is: Sports in a living room. The TV will be used to watch sports during the day, like football or hockey. Usually watched with a group, so from multiple viewing position.
Overall, this is a great TV for watching sports. The P Series Quantum X can get extremely bright and has great reflection handling, so there shouldn't be any issues with glare in a bright room. It has an excellent response time, so fast-moving objects, like the players, look great, with very little blur behind them. Unfortunately, this TV isn't well-suited for watching the big game with a group of friends, as the image degrades when viewed at an angle.
8.9 Video Games
What it is: Video games. The TV will be used to play video games, directly in front, in a controlled light environment. Usually fast games, like online FPS, where motion blur and input lag is important.
This is an excellent TV for playing video games. It has excellent low input lag for a responsive gaming experience, and it delivers very smooth motion with very little blur behind fast-moving objects. This TV also looks great in almost any room, as it can easily handle glare in a bright room, and also has excellent contrast for late-night gaming. Unfortunately, it doesn't support any advanced gaming features, like FreeSync. This TV also isn't as well-suited for co-op gaming, as the image degrades when viewed at an angle.
8.5 HDR Movies
What it is: HDR Movies and TV shows. The TV will be used to watch 4k UHD HDR content, with a wide color gamut and a high peak brightness. Either via UHD Blu-rays or HDR streaming.
Score components:
The P Series Quantum X is an excellent TV for watching HDR movies in a dark room. It looks great in a dark room, as it has excellent contrast and a great local dimming feature. This is a remarkably bright TV, and small highlights in some scenes in HDR really stand out, the way the creator intended. This TV also has an outstanding color gamut and great color volume. Fast-moving objects look great, thanks to the fast response time, but this does result in a bit more noticeable stutter when watching movies.
8.6 HDR Gaming
What it is: HDR Gaming. The TV will be used to play HDR video games using consoles that support it or on current generation gaming PCs. Xbox One S, PS4 Pro, GTX 10 series and AMD RX series graphics cards.
This is an excellent TV for HDR gaming. It has excellent low input lag, delivering a responsive gaming experience, and fast-moving objects in your favorite games look great, thanks to the fast response time. HDR games can get extremely bright, and they look great in a dark room, thanks to the excellent contrast ratio. Unfortunately, it lacks any advanced gaming features, like support for FreeSync variable refresh rate.
8.6 PC Monitor
What it is: PC Monitor. The TV will be used as a PC monitor, from 2-3 feet away, either for productivity purposes or gaming. Sharp text is important, as well as a high resolution.
Score components:
Overall, this is an excellent TV for use as a PC monitor. It has a fast response time, so there is little distracting blur trail around fast-moving objects, and it has excellent low input lag for a responsive experience. It can also get extremely bright and has excellent reflection handling, so it has no issues overcoming glare. Unfortunately, this TV has a poor viewing angle, and the sides of the screen appear non-uniform if you're sitting too close.
