The Vizio M Series 2018 is a good 4k TV for a wide range of usages. It has a high native contrast ratio so blacks appear deep in a dark room, but unfortunately, the local dimming doesn't work well to improve them further. It can also get bright to overcome glare but can't produce bright or saturated HDR highlights. Motion handling is also decent, but the image degrades when viewed at an angle. Unlike last year's Vizio M Series, the 2018 model includes a TV tuner.

Our Verdict

7.5 Mixed Usage

The Vizio M65-F0 is a good TV for mixed usage. It has good picture quality and works well in a dark room. It also has great motion handling and excellent low input lag, perfect for gaming or fast-moving action scenes.

  • Deep and uniform blacks
  • Excellent low input lag
  • Fast response time
  • Image degrades when viewed at an angle
7.9 Movies

Good TV for watching movies in a dark room. The native contrast is good, but not as good as most VA TVs. The local dimming feature is decent, but not very effective at boosting the black levels. It has excellent black uniformity with very little clouding.

7.5 TV Shows

Decent TV for watching TV Shows in a bright room. The Vizio M Series 2018 has good reflection handling and gets decently bright, but can't overcome glare in a very bright room. The viewing angle is bad, and if you like to work around the house while watching TV, you will be disappointed.

7.4 Sports

Good TV for watching Sports during the day. The Vizio M65-F0 has good reflection handling and great peak brightness but it can't overcome bright glare. The viewing angle is bad, which isn't great for watching the big game with a group of friends.

7.6 Video Games

Great TV for playing video games. Input lag is excellent and low across all supported resolutions and modes as long as Game Modeis used. There is very little motion blur and it has a great flicker feature that can improve the clarity of motion without significantly reducing the brightness.

7.5 HDR Movies

Good TV for watching movies in HDR. The native contrast ratio is excellent, and dark room performance is great. The local dimming feature is poor, and isn't very efficient. It doesn't support a wide color gamut and some scenes will lack detail in HDR.

7.3 HDR Gaming

Great TV for gaming in HDR. It has excellent low input lag and there is very little motion blur thanks to the fast pixel response time. Decent brightness with HDR content and it has good dark room performance. It doesn't support a wide color gamut which negatively affects the color volume.

7.3 PC Monitor

Good performance when used as a PC Monitor. The pixel response time is fast and it has great low input lag so navigating with a mouse feels responsive. It supports chroma 4:4:4 and text looks crisp. The viewing angle is bad and it will need to placed a few feet away from the viewing area otherwise the edge of the screen will fade.

Test Results

Curved No

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"

Wall Mount VESA 400x200

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.

Borders 0.39" (1.0 cm)

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

Max Thickness 2.40" (6.1 cm)

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.

Build Quality

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.

Local Dimming
Local Dimming

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 ( 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 ( 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 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.

Picture Quality
480p Input

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.

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.

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

Response Time

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.

PWM Dimming Frequency
480 Hz

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.

Motion Interpolation

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
