Vizio P Series Quantum vs Quabtum X 2019 Review

Vizio P Series Quantum and Quantum X are the second-top and top model of Vizio 4K HDR TV lineup for 2019. The Vizio P Series Quantum 2019 is direct replacement of the Vizio P Series 2018 (P65-F1, P75-F1) while the P Series Quantum X 2019is the direct replacement of the 2018 Vizio P Series Quantum (PQ65-F1). In here, there is a bit change in its 2019 lineup from the 2018 lineup. If in the 2018, P Series Quantum is the top model of the line-up, in 2019, it is no longer the top model. Its position was replaced by the P Series Quantum X while the P Series Quantum now sits at second-top model of the 2019 lineup. In the market, they are equally available in 2 screen sizes options, which are 65 inches (P659-G1 vs PX65-G1) and 75 inches (P759-G1 vs PX75-G1). And with the same screen size, the Vizio P Series Quantum X has hundreds of dollar more expensive price than the Quantum P Series. So, what are the differences between them and which one is a better choice?

Vizio P Series Quantum and Quantum X 2019 Features and Technologies

Panel Technology

The image is only an illustration

Both the 2019 Vizio P Series Quantum and Quantum X use the same panel technology, which is VA (Vertical Alignment). As we have known, a TV that uses VA panel usually has excellent native contrast ratio but at the same time, its side viewing angle coverage usually is poor. They both also have the same backlight technology, which is Direct LED with Full Array Local Dimming. But even so, that distinguishes between them is the number of dimming zones of their local dimming where the P Series Quantum X has more dimming zones than the P Series Quantum. .  Meanwhile, for improving their color gamut, they both are powered by Quantum Color Spectrum technology that based on the Quantum Dot Technology. Additionally, they both also have a technology called “Active Pixel Tuning” that  can automatically adapts to on-screen detail through intelligent pixel-level brightness adjustments for optimized accuracy and contrast.

Image Processor

For delivering 4K HDR images with full fine details, both the 2019 Vizio P Series Quantum and Quantum X are powered by Octa Core Processor. Additionally, this chipset also allows them to stream 4K content from most major streaming apps smoothly without any major issue. Meanwhile, they both are also supported by Spatial Scaling Engine, a 4K up-scaling engine that allows you to watch non UHD content in 4K quality with fine details preserved well.

HDR Supports

The Vizio P Series Quantum and Quantum X 2019 supports not only one HDR format. In addition HDR10, they both also support HLG (Hybrid Log Gamma), a HDR format developed by NHK and BBC for TV broadcasting. This means, if possible, they both allow you to watch TV Shows in HDR quality. Additionally, they both also support Dolby Vision, a proprietary HDR format by Dolby Vision that already uses dynamic metadata. Nevertheless, they both don’t support HDR10+, the other dynamic HDR format developed by Samsung and its alliance.

Motion Technology

For maximizing their performance in handling motion, they both are powered by Clear Action 960 Technology. Nevertheless, basically they both have native 120 Hz refresh rate panel. This allows them can play any content with native frame rate up to 120 Hz. Additionally, this also allows them are able to interpolate the lower frame rate content up to 120 Hz.

Meanwhile, to dim their backlight, they both use PWM (Pulse Width Modulation) dimming system with frequency of 120 Hz. Since their dimming frequency is not too high, their backlight flicker may bother some people who sensitive to flickers. Additionally, the 120 Hz flicker may be able to make motion look a bit crisper, but on the other hand this will cause some duplication in motion.

The Vizio P Series Quantum and Quantum X also have an optional BFI (Black Frame Insertion) mode. Enabling this feature will reduce their flicker frequency to 60 Hz. This feature is very helpful to make motion crisper, particularly when they are playing 60 fps content like sports or video games. To enable this feature, you just need to set the “Clear Action” to “on”. But even so, since enabling this feature will cause their backlight frequency change to 60 Hz, this certainly makes their backlight flicker is more noticeable and may bother some people.

Inputs

As we see on comparison table above, both of them are equipped with 5 HDMI ports. They both support most common input formats. But unfortunately, their HDMI ports don’t support 1440p resolution, which might disappoint some gamers. Additionally, all of their HDMI ports support CEC and HDCP 2.2. Except HDMI 5, their HDMI ports also support HDMI 2.0 Full bandwidth. They both also support ARC (Audio Return Channel) on HDMI 1. Special for HDMI 5, it is designed for low latency port.  This means, it has lower input lag than other ports. But on the other hand, this port has low bandwidth that means it doesn’t support HDR and some high-bandwidth format like 4K @60 @ 4:4:4.

Vizio P Series Input

While they both have more number of HDMI ports than most TV currently on the market, they both are only equipped with 1 USB port, less than most TVs.  IN addition to HDMI and USB ports they both also have 1 RF In, 1 Component In (Shared), 1 Composite In (Shared), 1 Digital Audio Out (Optical, 1 Analog Audio Out (RCA), and Ethernet port. For wireless connection, they both are also equipped with built-in Wi-Fi 802.11ac.

Smart TV Platform

Vizio SmartCast 3.0

As their smart TV platform, both Vizio P Series Quantum and Quantum X run SmartCast 3.0. Its interface has great design and very easy to use. But unfortunately, their built-in apps are not as many as other Smart TV platform. Unlike other smart TV platform which have apps store, so you can add and remove apps according to your wishes, it doesn’t has apps store. This means, except its built-in apps, you cannot add more apps. But even so, they are still provides some most popular apps like Netflix, YouTube, Amazon Prime Video, Live TVs, and more. Additionally, it also has built-in ChromeCast and also supports Apple AirPlay2. They both support voice control and works with Google Assistant, Apple Siri, and Amazon Alexa. But since it lacks built-in voice assistant found on Sony, LG, or Samsung TVs,  and its remote doesn’t has built-in microphone, you need other compatible smart device like such as Google Home Devices, Alexa Smart Speaker or others.

The Differences

Local Dimming Zones

The major difference between the 2019’s Vizio P Series Quantum and Quantum X is the number of their local dimming zones.  As we see on comparison table, the number of local dimming zone of each screen size is also different. For the 65 inches model of P Series Quantum (P659-G1), it has 200 local dimming zones, while for the 75 inches model (P759-G1) it has 240 local dimming zones. Meanwhile, for P Series Quantum X, its 65 inches model (PX65-G1) has 384 local dimming zones while its 75 inches model (PX75-G1) has 480 local dimming zones. And as we have known, the more local dimming zones of the TV, the backlight lighting will be more precise.

Brightness Output

The Vizio P Series Quantum and Quantum X have a difference in brightness output level. As we see on comparison table above, for the P Series Quantum, its 65 inches model (P659-G1) has UltraBright 1100 while its the 75 inches model (P759-G1) has UltraBright 1200. Meanwhile, for the P Series Quantum X, its 65 inches model (PX65-G1) has UltraBright 3000 while its 75 inches model (PX75-G1) has UltraBright 2700. You need to know, the higher numerical index of their UltraBright, the brightness level reached by them is brighter. As the example, with UltraBright 3000, the PX65-G1 has brighter peak brightness than the P659-G1 that has UltraBright 1200.

Vizio P Series Quantum vs Quantum X Performance

Black Level and Contrast

The Vizio P Series Quantum X2019 has a bit higher native contrast ratio than the P Series Quantum. The native contras ratio of Quantum X is around 5500:1 while the P Series Quantum is around 4200:1. Additionally, they both also have excellent local dimming features which is able to boost their contrast ratio significantly, up to around 9000:1 for the P Series Quantum and around 15000:1 for the Quantum X. The result, the P Series Quantum X can produce deeper black than the P Series Quantum. Their local dimming feature can boost not only their contrast ratio, but can also well handle blooming. Even though some blooming might be still noticeable around very bright object, but its performance is still better than most LED TVs.

High vs Low Contrast

The image is only an illustration

But even so, regardless their difference, their contrast ratio is equally great, allow them can produce extremely deep black.   Combination of extremely deep black, great local dimming feature, and good black uniformity makes their performance in a dark room is really great. Dark scene looks excellent on the screen. Even with HDR content, shadow details can be revealed excellently the way they should in HDR.

Winner: P Series Quantum X

SDR Peak Brightness

The Vizio P Series Quantum X 2019 has brighter SDR peak brightness than the P Series Quantum. With real content, overall, the P Series Quantum X is able to hit brighter than 600 nits while the P Series Quantum hit around 450 nits. But even so, their peak brightness varies depends on the content.  They both hit their brightest peak brightness is on 10%-25% window (10%-25% of the screen is bright while the rest is dark), where the P Series Quantum X hit around 1700 nits while the P series quantum hit around 700 nits. Meanwhile, they hit their low peak brightness on 100% window (the entire screen is bright), which is around 600 nits for the P Series Quantum X and around 400 nits for P Series Quantum.

With this behavior, can be ascertained, the peak brightness of the Quantum X really outstanding, very close to the Sony A9F or the 2018 P Series quantum. It can be easily to fight the glare in bright room, even with a lot of windows or lights. And of course, combined to its excellent reflection handling, this allows you to watch TV in a bright room without distracting glare. On the other hand, although not as bright as the Quantum X, peak brightness of the 2019 Vizio P Series Quantum is also bright enough to fight the glare in most bright rooms. Additionally, it reflection handling might be also not as good as the Quantum X, but in general, it is still good. And combination among them certainly makes its performance in a bright room is also great.

Winner: P Series Quantum X

HDR Peak brightness

Meanwhile, with HDR content, they both can even hit brighter peak brightness. With real content, the P Series quantum hit around 1400 nits while the P Series Quantum 2019 hit around 600 nits. However, just like with SDR content, in HDR, their peak brightness also depends on the content. They both hit their brightest peak brightness is on 10%-25% window where the P Series Quantum hit around 600-700 nits while the P Series Quantum X hit around 1700 nits. Even for a short time, on 10% window, the Quantum X can hit around 2400 nits. Meanwhile, on 100% window or when they are showing the entire screen is bright, the P Series Quantum hit around 400 nits while the P Series Quantum X hit around 600 nits.

With this behavior, can be ascertained, the P Series Quantum X can show the HDR images extremely bright. Even when it is showing bright scenes, they can still be shown fairly bright. Small highlight can even be shown outstandingly. With its peak brightness’ behavior, of course, it is able to show HDR images with popped detail. Even in some certain scene, it can show HDR images in 1000-4000 nits of brightness range intended by the content creator that means it is outstanding. On the other hand, although not as great as the P Series Quantum X, peal brightness of the P Series Quantum 2019 also bright enough to show HDR images as bright as they should be. In certain scene, details still pop. It is also able to show small highlight very bright the way they should in HDR. But unfortunately, this doesn’t still meet content creator’s intent.

Winner: P Series Quantum X

Color Gamut and Volume

Wide color gamut

The image is only illustration

Both of the 2019 Vizio P Series Quantum and Quantum X have excellent color gamut, even better than OLED TV or Samsung QLED TV. Their color gamut can cover around 98% of DCI P3 uv and around 96% of DCI P3 xy. Meanwhile, in Rec.2020, their color gamut coverage is even the best that ever. The P Series Quantum X can cover around 79% of Rec.2020 xy and 86% of Rec.2020 uv, while the color coverage of the P Series Quantum is a bit worse, which is around 78% in Rec.2020 xy and 83% in Rec.2020 uv.  On the other hand, they both also have great color volume. They both can show dark deep saturated colors and very bright saturated colors fairly well. But just like most LED TVs, blues cannot be show as bright as other colors or pure white. Nevertheless, overall, combination of their excellent color volume and great color gamut makes color of HRD images displayed on their screen looks very accurately, regardless they are showing bright scene or dark scene.

Winner: P Series Quantum X

Color Gradient

While they both have great color volume and color gamut, when playing 10 bit images, their color gradient is only decent, worse than most HDR TVs. There is some small banding in almost all colors and will be more noticeable in dark greens and grays shades.  Special for P Series Quantum X, it actually has a feature named “Reduce Noise”. But unfortunately, this feature can do much to improve its color gradient. On the other hand, the P-Series Quantum doesn’t have a feature that can be used to improve its color gradient. Meanwhile, compare between them, the P Series Quantum has a bit better color gradient than the Quantum X.

Winner: P Series Quantum

Side Viewing Angle

Just like most TVs with VA panel, the 2019’s Vizio P Series Quantum and Quantum X also has poor side viewing angle. Less than 15 degrees off center and front, their black level will start to rise. Meanwhile, at a bit more than 20 degrees, their colors also start to appear washed out. And finally, they will lose their peak brightness started at around 35 degrees. Of course, when you watch TV from the side, even from slightly angle, the picture displayed on their screen is starting to appear washed out. Special for the P Series Quantum X, it also actually has a feature called “Enhanced Viewing Angle” that expected can improve its side viewing angle coverage. But unfortunately, this feature doesn’t work well in improving its viewing angle performance.

Winner: Draw

Motion Handling

Both of these Visio TVs have excellent pixel response time and among LED TVs, their response time s including the best. The result, when they are playing fast moving images like sports or fast games, motion looks very clear on their screen with almost no motion blur. There may be some inverse ghosting that caused by some overshoot in some transitions, but this should not be noticeable in normal content. Meanwhile, some blur or duplications in motion that visible is more due to their 120 Hz backlight flicker. But just we have mentioned above, they both have an optional BFI (Black Frame Insertion mode) that can be enabled by enabling “Clear Action” feature. Enabling this feature will cause their backlight flicker change to 60 that can help to make motion crisper. But since their backlight flickers at lower frequency, this will cause their backlight flicker is more visible and may bother some people.

Pixel Response timemobil

Meanwhile, when playing 24p movies, their performance is also similar. They both can only play movies with judder-free without additional setting only if the source is native 24p movies like DVD movies or Blu Ray movies and movies from streaming apps like Netflix, Amazon Videos, and others. Meanwhile, when the source is 24p via 60p signal like movies from streaming devices or via 60i signal like movies from satellite devices, to remove the judder, you need to set the “Reduce Judder” slider to 1. But on the other hand, this might introduce some motion interpolation.

Winner: Draw

Input Lags

The 2019’s Vizio P Series Quantum and Quantum X have similar input lags and their input lags are excellent. Unlike most TVs where their lowest latency mode is when their picture mode is set in “Game Mode”, on both, the lowest latency mode can be enabled from any picture mode. You can enable this mode by enabling the “Low Latency” setting. Additionally, unlike other TVs where their input lags of each port are usually similar, the both have a port that has lowest input lags, which is on HDMI 5.  On their HDMI 5, with 60 fps content, their input lags are around 15 ms on both 1080p and 4K resolution, while with 120 fps content, their input lag is around 10 ms. But as we have mentioned, their HDMI 5 doesn’t support content that has high bandwidth like HDR or 4K@60Hz@4:4:4, and others.

Meanwhile, even though not as low as HDMI 5, the input lags of their HDMI ports outside HDMI 5 are also fairly low. Regardless the format and resolution, at 60 Hz, their input lag is around 26 ms while at 120 Hz, their input lag is around 30 ms. This actually is also low enough to make them is very responsive for any games, but of course not as responsive as on HDMI 5. Overall, both of them are very responsive when used for playing games, even for fast paced games. But a bit unfortunate, they both don’t any feature that can improve their games experience like VRR technology or ALLM.

Conclusion

For Watching Movies

Both of the Vizio P Series Quantum and Quantum X are great TVs for watching movies in a dark room. They both have outstanding contrast ratio that allows them can produce extremely deep black. Additionally, they both also have excellent local dimming feature that can improve their performance in a dark room. If you like car racing or fast action movies like “Fast and Furious”, they both also have excellent motion handling, makes motion in movies looks very smooth. But a bit unfortunate, they both cannot show 24p movies via 60i and 60p signal such as movies from streaming devices or satellite TV judder-free. But even so, if the source is DVD or Blur Ray movies or movies from native apps like Netflix, Amazon Videos, and others, they both can show them with judder-free. In general, if you want use them to watch movies, you will not be disappointed. Meanwhile, compare between them, the P Series Quantum X is better due to it has deeper black, brighter peak brightness, a bit wider color gamut, and a bit better color volume than the P Series Quantum.

Winner: P Series Quantum X

For Watching Sports

Overall, they both also great TVs for watching sports. In addition they both have excellent picture quality, they both also have excellent motion handling, makes fast sport looks very smooth on their screen. Additionally, combination of great SDR peak brightness and good reflection handling allow you to watch sports in mort bright room without distracting glare. But unfortunately, their side viewing angle coverage is poor. This means, if you watch a big game with a group of your friend or family, some of you may get less accurate picture. And compare between them, since the P Series Quantum X has brighter SDR peak brightness and better anti reflecting coating, it is better than the P Series quantum, particularly when you watch sports in very bright room with a lot of lights or windows.

Winner: P Series Quantum X

Video Games

Both of them are also excellent TV for playing games. Combination of their outstanding response time, excellent picture quality, and excellent low input lag on the dedicated low-latency HDMI port allows you to play games responsively with excellent picture quality and smooth motion. Nevertheless, the input lags on other ports actually are also low enough to make them very responsive for any games. Additionally, if you have non 4K game console, they both able to up-scale 1080p games to  4K resolution and looks almost as good as native 4K games. But unfortunately, they both don’t support any VRR technologies like FreeSync, GSync, or HDMI Forum that can improve their game experience. And since they both have poor side viewing angle, if you play game with a group of your friend or family, some of you may get less accurate picture quality. Meanwhile, its brighter peak brightness makes the P Series Quantum X is better when used for playing games in a very bright room.

Winner: P Series Quantum X

HDR Experience

The Vizio P Series Quantum X2019 has outstanding HDR experience. It is able to produce extremely black and has excellent black uniformity and excellent local dimming, allows it can show dark scene of HDR images excellently with popped shadow details. Additionally, combination of wide color gamut and good color volume allows it can show HDR images colorfully. And the remarkable thing is that it has remarkable HDR peak brightness, allow it is able show HDR images as bright as they should be. In some scene, it even is able to show small highlight looks stand out, the way the creator intended. But unfortunately, their color gradient is only decent, so color gradient of HDR images displayed o it screen cannot be shown as smooth as other TVs.

On the other hand, although not as great as Quantum X, the Vizio P Series Quantum also able to show HDR images excellently.  It also has deep black, good black uniformity, and excellent local dimming, make dark scene of HDR images is shown excellently, even when it is set in a dark room. Their color gamut and color volume that is not far different to Quantum X also allow it can show most colors of HDR images accurately, regardless its showing HDR10, HLG, or Dolby Vision Content. Its peak brightness may be not as bright as Quantum X and it may be not able to show small highlight as bright the way the creator intended, but its HDR peak brightness is still bright enough to make HDR details pops and show small highlights stand out the way they should in HDR. But just like the Quantum X, its color gradient is only decent, so it cannot show HDR images with color gradient as smooth as other TVs.

Winner: P Series Quantum X

Summary

As we have discussed a lot above, both of the Vizio P Series Quantum and Quantum X 2019 are greats TVs for mixed usage. Regardless they both are used for watching movies, sports TV Shows, playing games, or watching HDR contents, their performance is very satisfying. Nevertheless, of course, they both also have some flaws. As is typical of VA TVs, they both also have poor side viewing angle that makes the picture displayed on their screen look less accurate when viewed from the side. Additionally, their color gradient is not also as smooth as most TVs.

Which one is a better choice between them? As we have discussed a lot above, the Vizio P Series Quantum X is better than the P Series Quantum in almost all aspects. It has deeper black, brighter SDR and HDR peak brightness, a bit wider color gamut, and a bit better color volume. Meanwhile, in term of motion handling, input lags, and smart TV experience, their performance is not far different. Now, the decision comes back to you according to your budget and performance. If you have an extra budget, the Vizio P Series Quantum X certainly is better. But even so, if you have a limited budget, performance of The P Series Quantum is not also disappointing.
