When comparing VIZIO M-Series 50" (M50-E1) vs Samsung NU7100 40" (UN40NU7100), the Slant community recommends VIZIO M-Series 50" (M50-E1) for most people. In the question“What are the best TVs?” VIZIO M-Series 50" (M50-E1) is ranked 5th while Samsung NU7100 40" (UN40NU7100) is ranked 161st. The most important reason people chose VIZIO M-Series 50" (M50-E1) is:
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.

Pro Great for HDR content

Pro Supports both HDR10 and Dolby Vision
The M-Series can play all HDR content because it supports both HDR10 & Dolby Vision formats.
Pro Great picture quality
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.
Pro Decent at handling 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.
Pro Comes with Chromecast built-in
You can stream content to the M-Series from smart devices or apps that support streaming media to Chromecast.
Pro Has a remote app for iOS & Android
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.
Pro Interface is ads-free
The M-Series has no ads on its interface.
Pro Versatile use
From games to movies, sports and use as a PC monitor, the NU7100 is a good TV for diverse usage. The balance of low input lag, good picture quality, and decent motion handling make sure of it.
Pro Handles darkness very well
Even though the NU7100 doesn’t have local dimming, watching TV in the dark is not a problem due to amazing black uniformity - the blacks are even and there are no clouding issues.
Contrast is remarkable too – blacks are deep, and whites are bright.
Pro Good for gaming
The TV is a great option for a PC monitor. Not only does the NU7100 have ideal low input lag thanks to the “_PC_” and “Game” modes, it also features support for most resolutions, except 1440p.
Another thing to note – Samsung’s app store has the Steam Link app, which lets you connect your PC to your TV and play games without needing to connect the Steam Link hardware.
Pro Doesn’t require a lot of setup
When you first turn on the TV, it basically walks you through the setup process and you can start properly using it in a matter of minutes.
Regarding picture quality, it’s also quite reasonable right out of the box. White balance (gray color inaccuracy) and color dE (color inaccuracy) could be tweaked down for better quality, but most people won’t notice a sizeable difference.
In case you can’t figure something out when setting up, the TV also has a handy “e-manual” button.
Pro Great smart features
The NU7100 has a smooth, fast, and easy-to-navigate interface with a lot of room for customization, so you can tailor it for easier access to your most-used apps.
Samsung’s app store has a huge and diverse app library, second only to the Google Play Store.
The SmartThings app allows the user to control the TV and other connected devices via their smartphone.
Con Local dimming could be better
Unless you're in a really dark room and the brightness is set to really high, the effects of local dimming on the M-Series isn't very noticeable. You'll be able to see some differences in dark scenes, but it's not enough to improve the picture quality by much. The contrast ratio with local dimming enabled increases from roughly 5500:1 to 5800:1, a difference that has little impact on the overall experience.
Con Interface can be sluggish and slow
The interface of VIZIO's SmartCast OS can sometimes be sluggish. Some users have reported experiencing choppy animations, frame drops when browsing through the menu, and slow response to input/selection.
Con Mediocre sound quality
The M-Series sounds too bassy and some details will be drowned out because of that. There is also noticeable distortion at high volumes.
Con Not suitable for group watching
The M-Series has a narrow viewing angle that makes it unsuitable for group watching.
Its picture quality gets worse when viewed from off-center angles. At just ≥20° off from the center, the colors start looking dull and blacks turns into grey.
Con Lacks TV tuner
The M-Series, along with several of VIZIO's latest TV lineups, does not have a TV tuner built-in. If you plan to watch local over-the-air broadcasts, you will need to purchase a TV tuner separately.
Con Not the best value choice for gaming
The M-Series is not the best choice for gaming in this price bracket due to its relatively high input lag of ~40ms. Gaming TVs requires low input lag so the player won't feel out of sync, which is why most of the TVs suitable for gaming have a low input lag of ≤20ms.
This may be negligible to some, but input lag can make a world of difference to demanding or competitive gamers.
Con Poor viewing angle
The quality of the picture degrades quite a lot when looking at the TV from the side – the brightness decreases, and colors get washed out, especially the blacks, which distort when watching even slightly off center.
All Samsung TVs run advertisements and the NU7100 is no exception. There is no way to turn them off or disable ad tracking.
Con Not great for HDR content
The NU7100 is best suited for standard-dynamic-range (SDR) content. It won’t be able to handle HDR content because of the weak color gamut and color volume (the amount of colors the TV can display).
Con Misperforms in light-filled environments
The TV’s peak brightness is not too good, so it’s best suited for rooms without a lot of light.
Even though the TV’s reflection handling is very good, it still won’t properly deal with them in brightly-lit rooms.
Con Mobile app has limited functionality
The SmartThings app won’t be able to completely replace the actual remote due to some drawbacks, such as no text input and no app launching possibilities, which are features that are absolutely necessary for a proper remote.
