Vizio M7 Series Quantum 2020 TV Review

The Vizio M7 Series Quantum 2020 is a budget TV from Vizio's 2020 lineup and a variant of the Vizio M8 Series Quantum 2020. It sits between the Vizio P Series Quantum 2020 and the Vizio V Series 2020. Its main competitors are the TCL 5 Series/S535 2020 QLED, the Hisense H8G, and the Samsung TU8000.

The Vizio M7 Series Quantum 2020 is a variant of the Vizio M8 Series Quantum 2020, and they look exactly alike. It has a simple design with thin borders on all sides and wide-set feet.

The feet are the same as the Vizio M8 Series Quantum 2020's. They're wide-set, so you need a large surface to put it on if you don't plan on wall-mounting it. They support the TV well and don't wobble much.

Footprint of the 65" stand: 50.4" x 11.8"

The back is simple and plain. The top portion is metal, while the bottom is plastic. All the inputs are easy to access when wall-mounted. Unfortunately, there's no cable management.

The borders are thin and aren't distracting.

The TV is relatively thin and shouldn't stick out much when wall-mounted.

The build quality is decent. It's made out of a mix of metal and plastic, and it feels sturdy overall. The only issue is that the plastic near the airflow vents on the back flexes a bit, but otherwise, there aren't any apparent gaps. The stand supports the TV well, and it doesn't wobble much. There are a couple of stuck pixels on our unit; however, your experience may vary.

The Vizio M65Q7-H1 has an excellent native contrast ratio, but unlike the Vizio M8 Series Quantum 2020, the local dimming (called Active Full-Array) lowers the contrast ratio instead of increasing it. The posted number is with local dimming set to 'Medium', which is the recommended setting. Set to 'High', the contrast is a bit higher at 5110:1. That said, the difference is minimal and shouldn't be noticeable to most people. Note that the contrast ratio can vary between individual units.

The Vizio M65Q7-H1 has decent SDR peak brightness, a bit lower than the Vizio M8 Series Quantum 2020. It's better suited for a dark to moderately-lit room, as it can struggle a bit in bright ones, especially if there's sunlight. Also, the brightness varies a lot depending on the scene.

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

If you don't mind losing image accuracy, you can get a brighter image in the 'Vivid' Picture Mode, with Active Full-Array set to 'High'. We measured a peak of 554 cd/m² in the 10% window using these settings.

The Vizio M65Q7-H1 has a mediocre local dimming feature. We recommend using the 'Medium' setting, which is what we used for testing. There's noticeably less blooming than the Vizio M8 Series Quantum 2020, but it's mainly due to how big the lighting zones are. This means that a larger area of the screen is lit, making the overall black level rise and blooming less noticeable. There's still some, although it's more visible when displaying our test pattern than in regular content. Subtitles are dimmed, and the large lighting zones and raised black level make the subtitles less distracting. It crushes blacks, so small highlights like distant stars disappear almost completely. Transitions are slow and visible, as the zones tend to light up too early and are slow to turn off.

The Vizio M65Q7-H1 has sub-par HDR peak brightness. Just like in SDR, the brightness varies a lot across different content and gets dimmer as more areas of the screen are lit. It isn't bright enough to deliver a satisfying HDR experience.

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

If you don't mind losing accuracy, you can get a brighter image by setting the Picture Mode to 'Vivid', Gamma to 2.2, Active Full-Array to 'High', Local Contrast to 'High', and Color Temperature to 'Cool'. We measured a peak brightness of 558.2 cd/m² in the 10% window using these settings.

Gray uniformity on our unit of the Vizio M65Q7-H1 is okay. There's a fair amount of dirty screen effect (DSE), which can be distracting when watching sports, wide panning shots, or any scenes that have a large area of uniform color. Uniformity is only slightly better in dark scenes, as the DSE is still visible, and the right side of the screen is brighter than the rest. Note that gray uniformity can vary between individual units.

Our unit of the Vizio M65Q7-H1 has decent black uniformity. Without local dimming, there's visible clouding and some backlight bleed. With local dimming enabled, uniformity is better, but the blooming is more visible, and it extends all the way to the edges of the screen. Note that black uniformity can vary between individual units.

Like most VA panel TVs, the viewing angles are sub-par. Image accuracy degrades as you move off-center, which isn't ideal for large rooms or wide seating areas. If you want a TV with wide viewing angles, check out the Sony X80J.

The Vizio M65Q7-H1's reflection handling is good. It handles bright ambient light well but has more difficulty with direct reflections. It's best to avoid placing the TV opposite a window or bright lights.

Out-of-the-box, the Vizio M65Q7-H1 has decent color accuracy. Most colors are inaccurate to varying degrees, and white balance is visibly off. The color temperature is warmer than our 6500K target, giving the image a reddish tint. Gamma is close to the 2.2 mark for the most part, but both dark and bright scenes are a little brighter than they should be. Note that color accuracy can vary between individual units.

After calibration, the color accuracy is exceptional. The remaining inaccuracies shouldn't be visible to the naked eye. White balance is nearly perfect, and the color temperature is much closer to our target. Gamma is better, but bright scenes are now over-darkened.

You can see our recommended settings here.

The Vizio M65Q7-H1's upscaling of 480p content is decent, but it isn't as good as most recent 4k TVs.

720p content, such as from cable TV, looks decent; there are no visible artifacts.

1080p content, such as from Blu-rays, looks almost as good as 4k.

Other than the stuck pixels on our unit, 4k content is displayed perfectly.

The Vizio M7 Series Quantum 2020 can't display an 8k signal.

As mentioned, our unit of the Vizio M7 Series Quantum 2020 has a few stuck pixels near the top of the screen, but we couldn't get a picture of them. This TV uses a BGR sub-pixel structure, which doesn't affect image quality, but it can affect text clarity when using the TV as a PC monitor. You can read more about it here.

The Vizio M65Q7-H1 has an outstanding HDR color gamut. It has 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, but the roll-off is sharp and flat, resulting in some clipping in very bright scenes. The 'Game' mode EOTF is nearly identical, which you can see here.

If you find HDR content too dim, you can make it brighter by setting Gamma to '1.8', Black Detail to 'High', Local Contrast to 'High', Active Full-Array to 'High', and Color Temperature to 'Warm'. These settings result in a brighter image, as you can see in this EOTF.

Excellent color volume. It only has difficulty displaying bright blues, which is typical for LCDs.

The gradient handling is great. There's only a little bit of banding in the greens and grays. Turning on Contour Smoothing removes most if not all of it; however, it can cause a loss of fine details in some scenes.

There are no signs of temporary image retention; however, this can vary between individual units.

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

The Vizio M65Q7-H1's response time is good, but it's a bit slow in the 0-20% transition, resulting in some motion smearing in dark scenes. There's a tiny amount of overshoot in the 0-20% and 0-80% transitions; however, it's much better than the Vizio M8 Series Quantum 2020 and shouldn't be noticeable for most people.

The Vizio M65Q7-H1's backlight is flicker-free when the TV's brightness is set to max. However, if it's set to anything below maximum, the backlight flickers at 480Hz.

The Vizio M65Q7-H1 has an optional Black Frame Insertion feature to help reduce motion blur. When enabled, the backlight's flickering frequency is 60Hz, but it can cause slight image duplication due to crosstalk. To use BFI, enable Clear Action.

The Vizio M7 Series Quantum 2020 doesn't have a motion interpolation feature.

Due to the Vizio M65Q7-H1's fast response time, there's some stutter in lower frame rate content.
