Vizio M Series 2018  TV Review

The design of the Vizio M Series 2018 is good. It has a sleek look and feels sturdy. The new stand and the thin metallic borders give it a more premium look. It still lacks any planning for cable management, but the good news is that the inputs are very close to the side.

This year's Vizio M-series comes with a sleek and sturdy looking stand. This is quite an aesthetic change from the wire-like stand used in the M-Series 2017.

Footprint of the 65" TV stand: 50.7" x 10.9"

The back of the TV is plastic. It has been redesigned and has a more sleek look and although the inputs have changed sides, they are still split between the bottom and the side edge. There is no planning for cable management.

The borders of this year's Vizio M65-F0 are thin and metal. However, there is a thick bezel around the screen.

The maximum thickness of the Vizio M65-F0 does not differ much from the 2017 M series. In this year's model, the structure of the TV (screen and electronics' compartment) is more apparent when the TV is viewed from the side.

The build quality is good for this Vizio M65-F0. The TV feels solid and has no major gaps. The tiny gap shown in the picture is hardly noticeable in reality and should not cause any problems. The stand provides the TV with good stability.

The contrast ratio of the Vizio M Series 2018 is very good but slightly worse than last years' model. Dark scenes produce nice blacks even in low-light environments.

The contrast ratio does not improve with local dimming enabled.

The Vizio M Series 2018 has a sub-standard Local Dimming. Clouding can be seen around moving objects and this might be more apparent when subtitled content is viewed.

The best results are obtained when local dimming (called Xtreme Black Engine Plus on this Vizio TV) is set to 'Medium'.

The SDR peak brightness of the Vizio M Series 2018 is very good. The TV reaches and maintains high brightness levels at most window sizes.

The testing was done with local dimming (called Xtreme Black Engine Plus on this Vizio TV) set to 'Medium'.

Update 08/15/2018: We have retested the SDR Peak Brightness on the latest firmware (1.0.18.4) and it remains the same.

The HDR peak brightness of the Vizio M Series 2018 is okay. It is very similar to last year's model.

The TV displays small bright details well in dark HDR scenes but fails to reach the 1000 nits HDR content is targeting.

The testing was done with local dimming (called Xtreme Black Engine Plus on this Vizio TV) set to 'Medium'.

Update 08/15/2018: We have retested the HDR Peak Brightness on the latest firmware (1.0.18.4) and it remains the same.

The gray uniformity of the Vizio M Series 65 is okay. At the 50% gray level, clouding is fairly noticeable in the center of the screen. Some dirty screen effect is visible during panning shots and sports viewing.

Results improve significantly at darker gray levels, where it gets hard to notice clouding.

The viewing angle is poor. Colors shift quickly and black washes out as soon as one moves away from the center, but the brightness stays at acceptable levels for bigger angles.

The black uniformity of the Vizio M Series 2018 is remarkable. There is some slight clouding to the right, but in general, the screen is very uniform.

With local dimming turned on, the uniformity is a little worse, as some blooming is obvious around the middle white cross while the rest of the screen remains mostly black.

The Vizio M Series 2018 handles reflections very well. In bright environments, the TV is able to overcome glare. However, it cannot handle direct reflections with the same efficiency due to the lack of an anti-reflective coating.

The VVizio M65-F0 has impressive color accuracy. When the picture mode is set to Calibrated Dark, both the white balance dE and the color dE are below 3, most people will not notice any imperfections.

The gamma is at 2.08 and fairly consistently below our target of 2.2. This makes shadows look darker, but again it will pass unnoticed by most people.

Colors and shadows of the Vizio M65-F0 after calibration are amazing. The already great accuracy becomes almost perfect in all aspects of our measurements. color dE and white balance dE are very small, whereas the gamma curve is followed perfectly at 2.2. Finally, the color temperature is spot on at 6500K

Note: Calibration can be performed very easily with the help of the 'Smartcast' app, as no on-screen menu is necessary.

Upscaling of low-quality content such as DVDs is a bit more blocky than other TVs and there is more noise, similar to the Vizio M Series 2017. This is visible when viewing DVDs.

Close-up comparison

Upscaling of 720p content such as cable is a bit softer than most other TVs.

1080p content such as Blu-rays look good. The image remains clear and sharp.

No issues can be seen with native 4k content.

The color gamut is okay for the Vizio M65-F0. It fails to cover either of the color spaces measured adequately and certainly falls below the threshold to be classified as having a wide color gamut.

In the Calibrated Dark picture mode, the HDR EOTF follows the target PQ curve fairly well, but with a bit of over-brightening in dark shades and an early roll-off of bright shades. The EOTFs in Calibrated Dark with Game Low Latency enabled and in the Computer picture mode are very similar to that of Calibrated Dark.

Mediocre color volume. The narrow color gamut prevents the TV from achieving a satisfying color volume. It has difficulty displaying deep, dark colors and does not cover either color space very well, although in the Rec.2020 it performs slightly better than the 2017 model.

The gradient performance is very good for this Vizio M Series 2018. It can display our gradient test image almost perfectly, with only small visible imperfections in dark green bands.

The TV has a Reduce Noise feature that may help reduce banding when banding is present in the content itself with the possible trade-off of some loss of fine detail. The Reduce Noise option, however, can not improve any banding that is added to the content, by the TV itself.

No image retention is present on the Vizio M65-F0. This is in line with TVs that use VA panels.

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

The Vizio M65-F0 has an excellent fast response time. There is very little motion trail behind fast-moving objects, most of the blur in the photo is due to persistence. There is a tiny bit of overshoot in some transitions, but these are too minor to cause any overshoot artifacts.

There is some dark haloing visible around the logo. This is likely due to the down transitions being much faster than the up transitions. In this case, the blue and green pixels of the background go dark before the red pixels in the logo can turn on. This is noticeable in most of the motion blur photos, but is especially noticeable on this TV.

There is backlight flicker at all backlight settings below 100. The flicker frequency is very high at 480 Hz, and most people won't notice it. At low backlight settings there is some decrease in amplitude as well as duty cycle. The backlight is identical to last year's M-Series.

The backlight of the Vizio M 2018 is much better than TVs with lower flicker frequencies like the LG SK9000, and very similar to the TCL R617.

The BFI mode on the M-Series 2018 is activated by setting Clear Action to On. Unlike most TVs, when BFI is enabled the perceived screen brightness is not reduced, as the brightness spikes higher than before to compensate for the off cycles. With BFI enabled the backlight can only flicker at 60 Hz.

The Vizio M65-F0 does not have a motion interpolation feature unlike most TVs we have reviewed.

There is some 24p stutter that is especially noticeable with wide panning shots. Unlike many other TVs, this cannot be reduced by enabling motion interpolation, as the M-Series does not have this feature.

Similar to the 2017 M-Series, the 2018 Vizio M65-F0 can play 24p content without judder, but only when played from a native 24p source like a Blu-ray player or from the native apps. To remove judder set Film mode to on

The Vizio M-Series 2018 does not support any of the variable refresh rate technologies, including AMD's Freesync 2.

The input lag is superb and almost half of last year's model. To achieve low input lag you must set the 'Game Low Latency' to on as its is the only setting that matters for input lag. All picture modes can have low input lag, however only the 'Computer' mode can show proper 4:4:4 color.

Aside: The TV treated the Leo Bodnar tool differently than the Leo Bodnar + HDFury chain, in a similar way as last year's M Series 2017, but on the M Series 2018 the input lag didn't change as a result. See the Additional Review Notes for more detail.

Most common resolutions are supported at 60Hz except 1440p. However, this TV does not support 120 Hz.

Only in 'Computer' picture mode can 4:4:4 color be displayed properly. This years' model can support 4k @ 60 Hz @ 4:2:2 or 4:4:4 color on all ports, but it works only when 'Full UHD Color' is enabled for that port.

4k @ 60Hz @ 4:4:4 + HDR is also supported.

The inputs on the side include sockets for Component input which is rare for a TV.

The rear inputs include an 'analog audio out' so you can use wireless headphones with no need for adaptors. Also, a 'Cable/Antenna' input is present to accommodate the TV tuner that is included in this year's model.

The frequency response is mediocre. Low-frequency extension (LFE) is at 107Hz, which means this TV doesn't produce a lot of thump or punch in the bass range. The response above the TV's LFE point is good, suggesting clear dialog reproduction. However, there is significant pumping and compression at louder volumes, and since this TV doesn't have a room correction system, it wasn't able to remove the modes of our test room around 200Hz. Additionally, this TV gets decently loud, but it may not be loud enough for large and noisy environments,

The distortion performance of the Vizio M65-F0 is decent. The overall amount of THD produced is within decent limits at 80dB SPL, and there is not a big jump in THD at maximum volume either. However, this TV doesn't get very loud.

The interface is very basic, there are no animations, just an animated loading icon when opening the menus. The apps are somewhat slow to load, and we couldn't even get the YouTube app to load.

Update 06/22/2018: The YouTube app now works, but we have not found why it was not working during our previous testing. At the time of testing, only 14 apps were visible because the TV was connected to a Canadian WiFi network by mistake; when we connected to our U.S.A. VPN network 4 more apps appeared: Fandango Now, NBC, YouTube TV and Hulu.

Update 11/15/2018: Vizio has added a 'WatchFree' input via a firmware update. This uses the free Pluto TV service on the backend, and is well integrated.

There are no ads in the interface of the Vizio M-Series 2018, but there is a large banner of suggested content that can't be disabled.

Extremely limited selection of apps and smart features. On our M65 there were only 11 apps, and there is no app store. The most common apps are there, but the YouTube app wouldn't open for us and we had to cast YouTube from a smart phone.

There was a bug during testing, when switching rapidly from HDR to SDR the settings would not change and would stay on the HDR settings. They would change back only when the TV was powered off.

Update 06/22/2018: The YouTube app now works, but we have not found why it was not working during our previous testing. At the time of testing, only 14 apps were visible because the TV was connected to a Canadian WiFi network by mistake; when we connected to our U.S.A. VPN network 4 more apps appeared: Fandango Now, NBC, YouTube TV and Hulu.

Update 08/07/2018: Support for 4K HDR streaming on Amazon Video has been added with firmware version 1.0.18.4. The review has been updated.

Very basic lightweight remote. The buttons are very small and can be hard to read for some people, but the layout is intuitive and easy to use. There are 6 button shortcuts for various streaming services at the top of the remote.

There is no voice control built in to the remote or on the TV, but if you have a separate Google Home or Amazon Alexa device they can interface with and control the TV.

Basic TV controls at the back of the TV. There is a power button, an input button, and a volume rocker.
