The Vizio P Series Quantum 2021 is a great TV that replaces the Vizio P Series Quantum 2020. It improves in a few areas compared to its predecessor, but there are some disappointments for a high-end 4k TV. It's still plagued with bugs and issues, like 4k @ 120Hz signals from PCs only working by limiting the color depth and chroma subsampling, but those signals work without issues from the PS5 and Xbox Series X. It supports FreeSync variable refresh rate (VRR) technology, but even that is limited to 60Hz with a 4k resolution. In terms of picture quality, it has a VA panel with a fantastic native contrast ratio, so it displays deep blacks and the decent full-array local dimming feature improves it. Even in well-lit rooms, it has amazing reflection handling and high peak brightness. Fans of 4k HDR movies should also enjoy it, but it's not so good for watching old movies on DVDs as it has trouble upscaling some lower-resolution content.
The Vizio P Series is great for most uses. It performs really well for watching movies in dark rooms thanks to its high contrast and decent local dimming feature. Even in well-lit rooms, it gets bright enough to combat glare and has amazing reflection handling. It's impressive for watching HDR content as it displays a wide color gamut and gets bright. It has a few gaming features like variable refresh rate support, but its response time is only decent, and it has issues with 4k games at 120fps.
The Vizio P Series is great for watching movies in dark rooms. It has a VA panel with a high native contrast that displays deep blacks, and it has a decent full-array local dimming feature to improve the contrast. It doesn't have trouble upscaling 1080p content like from Blu-rays, but we don't suggest using it for DVDs. Also, it removes judder from native 24p sources, but not via 60p or 60i sources.
The Vizio PQ9 is great for watching TV shows in a bright room. It gets bright enough to combat glare and has amazing reflection handling, so visibility shouldn't be an issue. You can cast anything you want from your phone if you want to stream your favorite shows. However, it's not as good as other 4k TVs at upscaling 720p content, and it has narrow viewing angles, so the image looks washed out at the sides.
The Vizio P Series TV is good for watching sports in well-lit environments. Its reflection handling is amazing, and it has excellent peak brightness, so glare shouldn't be an issue in most bright rooms. Sadly, you may notice motion blur with fast-moving players or balls because the response time is only decent. It also has narrow viewing angles, so it's not an ideal choice for watching the game in a large viewing area.
The Vizio P65Q9 is excellent for gaming. It has a 120Hz panel with FreeSync support, but there are some issues getting the VRR to work in 4k at 120Hz. Its HDMI 2.1 inputs also only seem to work to their full capabilities with consoles and not PCs. Input lag is really low, and even though it has a decent response time, there's still visible motion blur with fast-moving content.
The Vizio PQ9 is impressive for HDR content. Its VA panel displays deep and uniform blacks and the local dimming feature does a decent job at improving the picture quality in dark scenes. It displays a really wide color gamut for HDR content and gets bright enough to make highlights pop the way the creator intended.
The Vizio P Series Quantum TV is excellent for HDR gaming. It has excellent gaming performance thanks to its 120Hz panel, FreeSync support, and low input lag. It has HDMI 2.1 inputs, but there are issues properly displaying 4k games up to 120fps. In terms of HDR, it has a high native contrast, decent local dimming, a wide color gamut, and high peak brightness, so highlights pop and colors are vivid.
The Vizio P Series is great to use as a PC monitor. It has low input lag for a responsive desktop experience, but its response time is just decent. It has amazing reflection handling and excellent peak brightness if you want to use it in a bright room, but it has narrow viewing angles, so the edges look washed out if you sit too close. Also, it only displays chroma 4:4:4 with 1080p and 4k signals at 60Hz, as it can't do it with 120Hz signals.
The Vizio PQ9 looks similar to the Vizio M7 Series Quantum 2021, but the feet are more set inwards. It has a simple design with thin borders that aren't distracting in any way.
The Vizio P Series Quantum TV features unique feet that are designed to hold a soundbar on top. There's rubber padding on top of each foot to avoid scratching the feet or soundbar. You can raise the screen higher so that a soundbar doesn't block your view. In the regular position (pictured above), there's 1.38" from the feet to the screen, and raising them in the higher position gives you 3.5" of space, so most soundbars shouldn't block it.
Footprint of the 65" TV: 28" x 13.4".
The back has a more stylish design than past Vizio TVs as it has rounded edges. The top part is slightly textured metal and the bottom part is plastic designed to look like brushed aluminum. There are clips for cable management that you attach to the feet, and you can also attach them to the legs when in the raised position.
This TV is thicker than the Vizio P Series Quantum 2020, but it still shouldn't stick out too much when wall-mounted.
The Vizio P Series has great build quality. It feels well-built with metal around the frame that feels solid, but the plastic on the back flexes a bit more. The TV is stable on the stand, but it sways more forward and backward with the feet in the raised position.
The Vizio P Series has a VA panel with a high native contrast ratio to display deep blacks. The full-array local dimming feature does a great job at improving the contrast. It's better than the Vizio P Series Quantum 2020, but this can also vary between units.
Note: The 75 inch model has an IPS panel, so we expect it to have much worse contrast, resulting in blacks that look gray in a dark room.
The SDR peak brightness is excellent. It gets bright enough to fight glare in most well-lit rooms, and even though brightness varies between scenes, it shouldn't be that distracting for most people.
We tested the SDR peak brightness after calibration in the 'Calibrated (Dark)' Picture Mode with Gamma set to '2.2', Color Temperature to 'Warm' and Active Full Array on 'High'.
If you want an even brighter image and don't care about accuracy, we reached an astonishing 1,127 nits in the 10% window using the same settings but in the 'Vivid' Picture Mode and Local Contrast on 'High'.
The Vizio P Series has a decent local dimming feature. It's an improvement over the Vizio P Series Quantum 2020, but it's not enough to increase the score. There are 144 zones on the 65 inch model, and the 75 inch is advertised to have 210 zones, meaning local dimming may perform a bit differently, but not much because the number of zones is proportional to the size. The setting for the local dimming is called Active Full Array and we suggest setting it to 'High'.
There's blooming around bright objects, which affects the uniformity, but it's not as bad as the 2020 model. Subtitles also have blooming around them to the point where it bleeds into nearby areas, like the black bars at the bottom of the screen. When there's a bright object in a dark scene, the local dimming averages out the dimming between zones, causing some blacks to look gray. In terms of fast-moving objects, they transition between zones well in real content. The zone transitions are more noticeable with our test patterns, but most people won't watch content like this. The local dimming improves the contrast but also adds blooming issues.
The local dimming feature looks the same in Game Mode as outside of it.
The Vizio PQ9 has impressive HDR peak brightness. Surprisingly, our test slides are about the same brightness as in SDR, but the real scene brightness is much higher, so it's bright enough to make highlights pop. The EOTF follows the target fairly well, but most scenes are slightly over-brightened. Also, there's a sharp roll-off once the TV hits its peak brightness, so extremely bright scenes lose details.
We measured it with the same settings as the SDR peak brightness, but in HDR. If you find the image too dark, set the Gamma to '1.8', Color Temperature to 'Cool', and Local Contrast to 'High'. The image appears noticeably brighter, as you can see in this EOTF, but it doesn't affect the peak brightness, and the roll-off is even worse.
The HDR brightness is once again impressive in Game Mode. The image looks the same as outside of Game Mode because you don't need to change the Picture Mode but rather just enable the Game Low Latency setting.
The gray uniformity is decent, but this can vary between units. There are blotchy parts throughout, including dirty screen effect in the center which could get distracting during sports. Uniformity is better in near-dark scenes, but there's also some backlight bleed at the left and right edges.
The black uniformity is excellent. It's good without the local dimming feature enabled, but the screen looks more blue, and there's still a bit of backlight bleed. The local dimming helps further deepen any blacks and remove any backlight bleed, but it also causes more blooming around the center cross. Keep in mind that uniformity can vary a bit between units.
The Vizio P Series has disappointing viewing angles, which is expected from a VA panel. Colors quickly start to shift, and the image looks too dark when viewing from the sides. There's an 'Advanced Viewing Angle' setting, but it doesn't seem to improve the viewing angles on other Vizio TVs, so we didn't measure the viewing angles with it enabled on this one.
Note: The 75 inch model has an IPS panel, so we expect it to have much better viewing angles than the 65 inch model.
The reflection handling is amazing. It handles even most light sources really well, and visibility shouldn't be an issue. However, because it has a glossy screen, direct light sources like lightbulbs are reflected at a strong intensity, almost like a mirror.
The Vizio P Series TV has good out-of-the-box accuracy. Color temperature is close to the 6500K target, and most colors are only slightly off, but blues are slightly over-saturated. White balance is also off, especially brighter whites. Gamma is okay, but most scenes are too dark and really bright scenes are over-brightened. Keep in mind that accuracy can vary between units.
The accuracy after calibration is fantastic. The color temperature, gamma, and white balance are all improved and you shouldn't notice many inaccuracies with those. Colors improved too, but we couldn't fix the blues without making the rest of the image inaccurate.

The Vizio P Series doesn't properly display 480p content in terms of the aspect ratio. It can't correctly show a 16:9 image in this resolution as there are black bars, which you can see in this photo. The photo above is cropped to remove the bars. We don't know how this TV displays 4:3 480p content because we only test with 16:9 content, but it's still not suggested for watching DVDs.
This TV does a decent job at upscaling 720p content, like from cable boxes, but it's not as good as other 4k TVs.
There aren't any issues with 1080p upscaling, which is great for watching Blu-rays.
The Vizio PQ9 displays native 4k content perfectly. However, if you enable the Advanced Viewing Angle setting, you may notice some dithering so we suggest leaving it off.
The Vizio P Series has an amazing color gamut for HDR content. It has exceptional coverage of the DCI P3 color gamut used by most content, and its coverage of the wider Rec. 2020 is also very good.
The color volume is good. It displays colors at a wide range of colors well, but it's not as good as the Vizio P Series Quantum 2020 because that TV displays a slightly wider color gamut. However, most people won't be able to tell the difference.
The gradient handling is impressive. There's banding in the darker shades, but other than that you shouldn't notice it much. There's a Contour Smoothing that helps smooth out banding a bit, but that comes at the loss of fine details.
There are no signs of temporary image retention on our unit, but this can vary.
We don't expect VA panels to experience permanent image retention, as the VA panel in our long-term test appears immune.
The Vizio P Series has a decent response time, but it's much worse than the Vizio P Series Quantum 2020. It's noticeably slow in dark transitions, leading to black smearing with darker objects. Overall, you'll notice motion blur with most content, and you may also notice image duplication due to the backlight flicker.
The Vizio P Series uses pulse width modulation (PWM) to dim its backlight if you set the Backlight setting to anything below its max. It flickers at 240Hz, including with Game Low Latency enabled, which could lead to some image duplication.
There's a backlight strobing feature, which is also known as black frame insertion, to try to clear up persistence blur. It only flickers at 60Hz and doesn't work that well because the timing of the strobing is off, creating image duplication. We saw a similar effect with the Vizio P Series Quantum 2020, but it's more noticeable on the 2021 model. Keep in mind that the BFI score is based on the flicker frequency, and not the actual performance.
The Vizio P Series has a motion interpolation feature, which causes the effect known as the soap opera effect. It interpolates 30fps and 60fps content up to 120fps, and it works well with slower scenes, but there are a ton of artifacts with fast-moving objects.
Due to the somewhat slower response time, there's not as much stutter on this TV.
Like other Vizio TVs, the Vizio P Series can only remove judder from native 24p sources, like Blu-ray players and native apps.
The Vizio P Series has a 120Hz panel with variable refresh rate support in the form of native FreeSync. G-SYNC doesn't work at all and we can't confirm if it supports HDMI Forum VRR because the Xbox Series X supports both HDMI Forum VRR and FreeSync, and we don't know which one is actively working. Unfortunately, it doesn't seem to support 4k @ 120Hz content from our PC above an 8-bit signal with chroma 4:2:0, so VRR doesn't work at that resolution. If you want a TV that supports VRR with 4k @ 120Hz signals, then look into the TCL 6 Series/R646 2021 QLED.
The Vizio P Series has low input lag for a responsive gaming experience. We didn't run into as many issues as we did with the Vizio P Series Quantum 2020, and we were able to get more consistent readings. Input lag remains low with most content, except it increases with 1080p @ 120Hz signals, which is the same behavior as the 2020 model. We were also able to measure the 4k @ 120Hz input lag by dropping the color depth to 8 bits and using a 4:2:0 signal.
The Vizio P Series supports 4k content up to 120Hz, but there are some quirks with it. It only displays 4k @ 120Hz content from a PC with an 8-bit signal and chroma 4:2:0, which falls under the HDMI 2.0 bandwidth. Even at that, we were originally only able to get that signal in Game Mode and not outside of it. After a few days of testing, we were able to reach it outside of Game Mode, but the screen would flicker black periodically. It displays 1440p signals only through a custom resolution, but even at that 1440p @ 120Hz only works in Game Mode while skipping frames and it's downscaled, and it doesn't work at all outside of Game Mode. The only resolution to properly work with a 120Hz refresh rate is 1080p.
This TV displays chroma 4:4:4 with 1080p and 4k content at 60Hz, but it's limited to 4:2:0 with any other signal.
Despite our issues with 4k @ 120Hz from our test PC, the Vizio P Series surprisingly supports any signal up to 4k @ 120Hz from either the PS5 or Xbox Series X. It has an Auto Low Latency Mode, too, which switches the TV into Game Mode when you play a game from a compatible device.
HDMI ports 3 and 4 are advertised to be HDMI 2.1, but we found they don't accept signals above the HDMI 2.0 bandwidth when connected to a PC. As mentioned in the Supported Resolutions section, we were only able to achieve a 4k @ 120Hz signal by dropping the color depth down to 8 bits and using chroma 4:2:0 instead. However, we still consider them HDMI 2.1 because it supports 4k @ 120Hz content from the PS5 or Xbox Series X.
Vizio dropped the Composite Inputs compared to the Vizio P Series Quantum 2020, which isn't ideal if you have old gaming consoles or a DVD player.
The Vizio P Series has eARC support through HDMI 1, and it can pass all common audio formats to a compatible receiver.
The Vizio P Series has an okay frequency response. It gets loud and has a fairly well-balanced sound profile, but you may hear some compression artifacts when listening at its max volume. Also, it doesn't produce much bass, so you should get a soundbar or a surround sound setup for the best audio experience possible.
The distortion performance is okay. There isn't too much distortion at moderate listening levels, but it gets more noticeable at its max volume. Even at that, not everyone may hear it, and it depends on the content.
The Vizio PQ9 comes with the updated version of the Vizio SmartCast system, but there isn't much difference with previous versions. The interface is user-friendly, but it feels slow and laggy at times, and we experienced a few bugs during testing:
There's suggested content on the home page and not ads, but we weren't able to get a photo of them during testing.
Vizio TVs don't come with an app store so you can only use the web-based apps it comes with. Luckily, there's a ton of apps available, including the most popular streaming services. It's advertised to support both Google Chromecast and Apple AirPlay 2 so you can cast almost anything you want from your phone.
The Vizio P Series comes with a new remote that has a built-in mic for voice control. You can ask it to change inputs and open apps, but you can't use it to change settings. You can also ask it to search for content on the homepage, and it will show you which app your movie/TV show is available on, but you can't use it to search for content in the apps themselves. As explained in the Interface section, we experienced an issue where the remote became buggy with the CEC feature enabled.
There's a single button underneath the left side of the TV to turn it On/Off and change inputs.
We tested the 65 inch Vizio P Series (P65Q9). It's also available in a 75 inch size (P75Q9-J01), but we've received confirmation that that size uses an IPS-style panel, so we expect it to perform differently from the model we bought. There's also an 85 inch P Series Quantum X 2021 model available, but our review isn't valid for that because it's advertised to get brighter and have more dimming zones.
If someone comes across a different type of panel or their P Series Quantum doesn't correspond to our review, let us know and we'll update the review. Note that some tests, like gray uniformity, may vary between individual units.
You can see the label of our unit here.
The Vizio P Series is a great TV with excellent overall picture quality in both dark and bright rooms. It's a slight improvement from the Vizio P Series Quantum 2020, but it has many of the same issues. There are too many bugs when it comes to gaming with VRR or at 120fps, and considering its price point, there are other gaming TVs that won't give you as many headaches.
The Sony X90J and the Vizio P Series Quantum 2021 are both great 4k TVs. HDR content looks better on the Vizio because it displays a wider color gamut, gets brighter in HDR, and has better black uniformity. The local dimming performs better overall on the Sony than the Vizio, but the 65 inch Vizio still has a higher native contrast. The Vizio also has much better reflection handling if you want to use it in a well-lit room. The Sony doesn't have VRR support like the Vizio, but that should come in a firmware update, and it doesn't have any issues with 4k content at 120fps like the way the Vizio does.
The LG C1 OLED and the Vizio P Series Quantum 2021 are different types of TVs. The LG has an OLED panel with a near-infinite contrast, perfect black uniformity, and wide viewing angles. The LG also has a much faster response time for better motion handling, and even though they each have similar gaming features, there are fewer bugs on the LG, providing a better gaming experience. On the other hand, the Vizio is an LED TV that gets much brighter so highlights pop in HDR, and it doesn't have the risk of permanent burn-in like OLEDs.
The Hisense U8G and the Vizio P Series Quantum 2021 are both great TVs, but the Hisense is more well-rounded. They each have a high contrast ratio on the 65 inch sizes, but the Hisense has better local dimming to display more uniform blacks. The Hisense has a much quicker response time, so motion looks better, and its gaming features don't have as many bugs as the Vizio as you can easily play 4k games up to 120fps. The Android TV interface is also better than Vizio's SmartCast system as it doesn't crash as much.
The Vizio P Series Quantum X 2020 and the Vizio P Series Quantum 2021 are both great 4k TVs. They have similar features and each use VA panels with a high contrast ratio, at least on the 65 inch sizes, but local dimming is better on the Quantum X because it displays deeper blacks and has better uniformity. The Quantum X also gets brighter in HDR, so highlights pop more. Motion looks smoother on the Quantum X due to the quicker response time. The Quantum comes with the new Vizio remote, which has voice control, and the Quantum X doesn't have that.
The Vizio P Series Quantum 2021 replaces the Vizio P Series Quantum 2020, and they're both great TVs. The 2021 improves in a few areas, like higher HDR peak brightness and better contrast and black uniformity, but this can vary between units. The 2021 model has trouble properly displaying 480p content, which we didn't see with the 2020 model. Motion looks a lot better on the 2020 model because it has a much quicker response time. They each have HDMI 2.1 inputs, and even though they both have trouble displaying 4k content at 120fps, the 2021 model doesn't have problems with the PS5 and Xbox Series X the way that the 2020 model did.
