The Vizio P Series Quantum 2020 is an overall good 4k TV. Like its predecessor, the Vizio P Series Quantum 2019, it sports a VA panel that displays deep and inky blacks, which is great for dark room viewing. It's good for bright rooms thanks to its high peak brightness and good reflection handling. It has a fast response time, an optional Black Frame Insertion feature, and can interpolate lower frame rate content up to 120 fps for fans of the soap opera effect. It has low input lag; however, its advertised variable refresh rate support isn't functional at the time of writing and would require a firmware update. Like most VA panels, it has poor viewing angles, so it isn't the best for wide seating areas. Also, its local dimming causes blooming around bright objects, which can be distracting. On the upside, it delivers a great HDR experience, as it has an excellent color gamut and gets bright enough to make highlights stand out.

Our Verdict

7.9 Mixed Usage

The Vizio P Series Quantum 2020 is an overall good TV. It has a high contrast ratio that allows it to produce deep blacks, making it great for watching movies in the dark. It has an excellent HDR color gamut, a full-array local dimming feature, and gets very bright to deliver a great HDR experience. Its fast response time results in minimal motion blur in fast-moving scenes and, combined with its low input lag, it's well-suited for playing video games. Unfortunately, it has poor viewing angles, and its local dimming causes a lot of blooming.

Pros
  • High contrast ratio.
  • Gets very bright.
  • Good reflection handling.
Cons
  • Poor viewing angles.
  • Some vignetting and dirty screen effect.
8.0 Movies

The Vizio P Series Quantum 2020 is great for watching movies. It delivers good picture quality thanks to its high contrast ratio, but its full-array local dimming causes a lot of blooming, and there's clouding throughout the screen on our unit, which can be distracting. On the upside, it upscales lower resolution movies well, and it can remove judder from 24p sources and native apps.

Pros
  • High contrast ratio.
  • Can remove judder from 24p sources and native apps.
Cons
  • Blooming around bright objects and subtitles.
  • Some vignetting and dirty screen effect.
7.6 TV Shows

The Vizio P Series Quantum 2020 is good for watching TV shows. It handles reflections well, and it gets bright enough to fight glare, so you shouldn't have any issues with visibility in broad daylight. However, its VA panel's poor viewing angles cause images to look washed out when viewed from the side, making it less ideal for those who like to walk around while watching TV.

Pros
  • Gets very bright.
  • Good reflection handling.
Cons
  • Poor viewing angles.
  • Some vignetting and dirty screen effect.
7.6 Sports

The Vizio P Series Quantum 2020 is good for watching sports. It has a fast response time that results in minimal motion blur and a Black Frame Insertion feature to improve clarity further. It handles reflections well, and it gets bright enough to overcome glare in well-lit environments. The viewing angles are poor, though, which isn't ideal for watching a big game with a large group of people.

Pros
  • Gets very bright.
  • Fast response time.
  • Good reflection handling.
Cons
  • Poor viewing angles.
  • Some vignetting and dirty screen effect.
8.2 Video Games

The Vizio P Series Quantum 2020 is great for gaming. It has a fast response time, and its low input lag and 120Hz refresh rate provide a responsive gaming experience. It can produce deep and inky blacks, making it a good option for gaming in the dark. It's advertised to have variable refresh rate support; however, it doesn't work at this time.

Pros
  • High contrast ratio.
  • Low input lag.
  • Fast response time.
Cons
  • VRR doesn't work.
8.1 HDR Movies

The Vizio P Series Quantum 2020 is great for watching movies in HDR. It has a high contrast ratio to produce deep blacks, an excellent color gamut, and a high peak brightness to make highlights pop. However, black uniformity isn't that good on our unit, and the local dimming feature causes a lot of blooming around bright objects.

Pros
  • High contrast ratio.
  • Gets very bright.
  • Can remove judder from 24p sources and native apps.
  • Excellent HDR color gamut.
Cons
  • Blooming around bright objects and subtitles.
  • Some vignetting and dirty screen effect.

The Vizio P Series Quantum 2020 is the Vizio P Series Quantum 2019's successor, sitting just below their flagship LED TV, the Vizio P Series Quantum X 2020. We expect the Sony X900H and the Samsung Q70T QLED to be its main competitors.

The Vizio P65Q9-H1 has an excellent design. It's minimalist, it has thin borders on all sides, and it looks good with the stand or mounted on the wall.

Design
Stand

The feet are set almost as wide as the TV itself and aren't reversible, so you need a large table if you don't plan on wall-mounting it. They support the TV well, but there's still a bit of wobble.

Footprint of the 65" stand: 50.7" x 11.7"

Back
Wall Mount VESA 400x400

The back is nearly identical to the Vizio P Series Quantum 2019. It's a lightly textured plastic, and there's no cable management.

Full-Array

The Vizio P Series Quantum has a decent full-array local dimming feature. It performs zone transitions relatively well, as it can follow slow-moving objects pretty closely, but it lags when there's faster movement. While zone transitions are visible when playing our test pattern, it isn't as bad in regular content.

There's a fair amount of blooming, more so in regular content than with our test pattern. It tends to make dark areas look grayish or over-brighten dark spots that have some form of light. It isn't always noticeable, but it can be distracting. Blooming isn't uniform, as some areas bloom more intensely than others. Unfortunately, subtitles aren't handled well. They're very bright, and there's a lot of blooming around them.

Even though the circle in our test pattern dims a lot when it's moving around quickly, it doesn't seem to be an issue in regular content. Unlike the Vizio P Series Quantum 2019, we find almost no difference between the 'Medium and the 'High' setting (local dimming is called Active Full-Array in the settings). The 'High' setting, which is the setting that we used, gets a little brighter but doesn't crush blacks as much as the 'Medium' setting.

On the 'High' setting, small highlights like stars look okay and aren't crushed. That said, there's blooming, and it doesn't happen on every star, which makes the screen look blotchy.

Excellent SDR peak brightness. It varies a lot depending on the scene, but overall, it's enough to overcome glare in a bright environment.

We measured the SDR peak brightness after calibration, using the 'Calibrated Dark' Picture Mode, with Backlight at max, Active Full-Array set to 'High', Gamma set to 2.2, and Color Temperature set to 'Warm'.

If you don't mind losing a bit of image accuracy, you can get a brighter picture using the 'Vivid' Picture Mode, with Backlight at max, Active Full-Array set to 'High', Gamma set to 2.2, and Color Temperature set to 'Cool'. We achieved a peak brightness of 1101 cd/m² in the 10% window using these settings.

Great HDR peak brightness. Like in SDR, there's a lot of brightness variability when displaying different content. It can get very bright, enough to deliver a good HDR experience.

We measured the HDR peak brightness before calibration, using the 'Calibrated Dark' Picture Mode, with Backlight at max, Active Full-Array set to 'High', Gamma set to '2.2', and Color Temperature set to 'Warm'.

If you want an even brighter image in HDR, set the Picture Mode to 'Vivid', with Active Full-Array set to 'High', and Color Temperature set to 'Cool'. We achieved a peak brightness of 1090 cd/m² in the 10% window using these settings.

Out-of-the-box, the Vizio P65Q9-H1 has good color accuracy. Most color inaccuracies are relatively minor, but white balance is off, and the color temperature is on the warm side, resulting in a slight reddish tint. Gamma follows the target reasonably well; however, both dark and bright scenes are over-brightened.

Note that color accuracy can vary between units.

The Vizio P65Q9-H1 has an excellent HDR color gamut. It has near full coverage of the commonly-used DCI P3 color space and great coverage of the wider Rec. 2020. The EOTF follows the PQ curve almost perfectly until the roll-off, and the 'Game' mode EOTF is nearly identical. If you find HDR content too dim, you can get a brighter image by setting the Picture Mode to 'Calibrated Dark', Active Full-Array to 'High', Gamma to '1.8', Backlight to max, and Local Contrast to 'Medium'. These settings result in a much brighter image, as you can see in this EOTF.

The Vizio P65Q9-H1 has an optional Black Frame Insertion (BFI) feature to improve motion clarity. Enabling it lowers the backlight's flickering frequency to 60Hz. Unfortunately, there's terrible strobe crosstalk, resulting in image duplication. To use BFI, turn on Clear Action.

This TV can interpolate lower frame rate content up to 120fps to make motion look smoother, otherwise known as the 'Soap Opera Effect'. It does a pretty good job in quiet to moderately fast-moving scenes, but there are artifacts if the action gets too intense. To interpolate 30fps content, increase Judder Reduction, and for 60fps content, increase Blur Reduction. These settings need to be adjusted depending on the content that you're watching.

The Vizio P65Q9-H1 is advertised to have HDMI Forum VRR support. However, it doesn't seem to be working at this time, even though our connected Xbox indicates that it's functioning correctly. It also caused a few crashes when enabled. We suspect that this is a bug that'll likely be fixed in a future firmware update. We'll retest it once it's available. To turn on VRR, set Game Low Latency and Variable Refresh Rate to 'On'.

Auto Low Latency Mode (ALLM)

The Vizio P65Q9-H1 has excellent low input lag, a nice improvement from the Vizio P Series Quantum 2019. It only rises slightly when playing with 10-bit HDR and shouldn't be noticeable to most people. There aren't any results for the latency with VRR since it doesn't work correctly at this time. Motion interpolation is usable when gaming; however, it adds significant input lag and isn't recommended.

To get the lowest input lag, set Game Low Latency to 'On'. You can also set it to 'Auto' if you want to enable the 'Auto Low Latency Mode', which turns the mode on automatically when the TV detects a game launching from a compatible device. For signals that require full bandwidth, Vizio has removed the Full UHD Color settings, so there's nothing to change.

For PC use, set Game Low Latency to 'On'. Vizio has removed the 'Computer' mode.

Note: We encountered a few issues while testing the input lag. The first is that the TV skips frames when playing 1080p or 1440p content at 120Hz with Game Low Latency on. The second is that the input lag results are very inconsistent at 120Hz, as they vary wildly between each run. Testing was done on multiple computers and we couldn't get consistent results on any of them. We suspect that this is a bug; we'll retest it once an update is available.
