VIZIO M-Series 50" (M50-E1) vs VIZIO P-Series 65" (P65-E1)

The M-Series is the best pick for HDR content in this price bracket. Compared to its direct competitors, it offers the best HDR experience because it has all the essentials for true HDR playback that its competitors lack: local dimming, fairly high peak brightness level, and a wide color gamut.

Its deep black levels are further improved with local dimming, which can make parts of the screen darker when the image calls for it. This results in a slight increase in overall picture quality - the black levels become deeper by a small margin, so highlights will stand out further.

Colors look vibrant in both dark and bright scenes, and the panel can reproduce the wide range of colors required for true HDR playback. In addition, it can also get bright enough to light up these colors sufficiently for HDR details to stand out, thanks to the peak brightness level of ~400 nits.

The M-Series can play all HDR content because it supports both HDR10 & Dolby Vision formats.

The M-Series looks great with vivid colors.

Dark scenes look amazing with great details, thanks to the panel’s contrast ratio of roughly 5500:1, which means it’s capable of producing blacks that are 5500 times darker than the brightest white pixel the screen can produce. This can be pushed slightly further to about 5800 with local dimming, which results in a slight increase in overall picture quality.

The colors are quite lifelike and accurate even without any calibration. They will look vibrant even in bright scenes because of the panel's high peak brightness levels of ~300 nits for SDR & ~400 nits for HDR.

Even in a decently-lit environment, the picture quality of the M-Series won't deteriorate by much. The panel is good at handling reflections and it can get adequately bright to fight off glare.

The M-Series is decent in bright environments.

The colors won't look dull thanks to the panel's high peak brightness levels and good handling of reflections. It's bright enough to fight off glare with peak brightness levels of ~300 nits for SDR & ~400 nits for HDR, and the intensity of reflections are reduced by panel's semi-gloss finish.

You can stream content to the M-Series from smart devices or apps that support streaming media to Chromecast.

The M-Series runs on VIZIO's SmartCast OS which has a brilliant, well-integrated phone and tablet app for iOS & Android. It can turn your smart device into a fully-functional remote, which makes it easy and convenient for you to control the TV without the physical remote. It's also particularly handy for text input, especially when it comes to searching for content from streaming services.

The M-Series has no ads on its interface.

The P65-E1 performs extremely well for HDR content thanks to its black levels, high native contrast ratio (4675:1, up to twice of that at 9271:1 with local dimming), and wide color gamut — all three of which are essential to HDR.

The P65-E1 runs on Vizio’s SmartCast OS, which has a remote app for iOS & Android capable of controlling the TV.

There are two different formats for HDR — HDR10 and Dolby Vision. Some TVs support only HDR10 and can't play Dolby Vision content. The P65-E1 supports both HDR10 and Dolby Vision, giving it the ability to play any HDR content in 2017.

Unlike the OLED panels in this price range, the P65-E1 has a VA panel and thus it does not suffer from image retention issues.

The user interface of modern smart TVs can include some advertisements similar to those on the internet or in a mobile app. The P65-E1 does not include any.

The P65-E1 can handle dark scenes very well thanks to its high native contrast levels, which clocks in at 4675:1 native, and it can go up to double of that at 9271:1 with local dimming enabled. This, along with good black levels and uniformity, gives the TV the ability to achieve great representations of dark scenes beyond most expectations.

The P65-E1 is versatile enough to be used for sports & gaming — its handling of motion blur is fantastic at ~11ms, and the input lag is only ~16ms which makes it good for gaming where input lag matters (but it is not suitable for HDR gaming because of the ~45ms of input lag for HDR content).

The P65-E1 is great at handling motion with very fast response time (~11ms). It will have no issues with displaying fast-moving objects — they will look smooth without any blur or lag.

The P65-E1 does a decent job with color accuracy — the colors are accurate out of the box and there is no calibration required, although it would benefit from some adjustments to the white balance. Color calibration is recommended to get the most out of this TV, but not necessary if you find it alright.

The black levels of a TV affects the viewer’s perception of other colors next to it. If the black levels are not deep enough and doesn’t remain uniform across the screen, the overall picture quality will look “flat” without much depth. The P65-E1 handles this well with only <0.8% deviation (across the entire screen) from what a pure black screen should be — this results in a significant gain in its native contrast levels, thereby increasing the picture quality.

The color gamut of a TV refers to the range of colors the display can reproduce — the wider the color gamut, the more colors it can display, and the better the overall picture quality will be. This is extremely important for HDR content because it requires a much wider color gamut than SDR content. This TV has a wide color gamut and have no issues with accurately reproducing the colors necessary for true HDR, although its color gamut is not as wide as other TVs in this price range (e.g. the Sony X900E).

The picture quality is great on the P65-E1. It has one of the highest contrast ratios in an LED TV when local dimming is enabled (9271:1), giving it the ability to produce very deep and uniform blacks. The brightness level for HDR is decent enough at ~450 nits to fight glare in bright environments without much picture quality degradation.

Local dimming is the TV's ability to dim areas of the screen for deeper black levels and better contrast — they are separated into different dimming zones, where each zone can be individually dimmed as needed. The local dimming on the P65-E1 is by far one of the best in LED TVs of 2017 (only beaten by the Sony X940E). It is capable of doubling the contrast levels from 4675:1 to 9271:1.

The P65-E1’s panel has a semi-gloss finish for diffusing the light across the screen evenly to decrease intensity. This, along with its ability to get quite bright (practically, it peaks at ~450 nits for HDR and can maintain this level of brightness), means that this TV is decent at handling reflections and performs okay in bright environments.
