When comparing Samsung NU7100 40" (UN40NU7100) vs Sony X850E 75" (XBR75X850E), the Slant community recommends Sony X850E 75" (XBR75X850E) for most people. In the question“What are the best TVs?” Sony X850E 75" (XBR75X850E) is ranked 43rd while Samsung NU7100 40" (UN40NU7100) is ranked 188th. The most important reason people chose Sony X850E 75" (XBR75X850E) is:
The X850E has a wide color gamut that allows it to reproduce the colors necessary for true HDR, and it has an average peak brightness level of ~400 nits that allows it to light up these colors properly. Thanks to that, HDR pictures look decent and highlights will look fairly good. However, the HDR performance can’t get better than that, due to the average peak brightness of ~400 nits which isn’t really enough for details to truly stand out, and it lacks local dimming.
Ranked in these QuestionsQuestion Ranking
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.
Pro Decent for HDR content
The X850E has a wide color gamut that allows it to reproduce the colors necessary for true HDR, and it has an average peak brightness level of ~400 nits that allows it to light up these colors properly. Thanks to that, HDR pictures look decent and highlights will look fairly good.
However, the HDR performance can’t get better than that, due to the average peak brightness of ~400 nits which isn’t really enough for details to truly stand out, and it lacks local dimming.
Pro Good for sports
The X850E looks fluid thanks to its excellent color uniformity and decent handling of motion.
It can display large, same-color objects like football fields really well - they will look natural and uniform.
Fast-moving objects, like football, will also look smooth. The panel only requires ~14ms to fully change the pixels color, resulting in fast-moving objects not leaving any trails on the screen, eliminating virtually all motion blur.
Pro Great ecosystem of third-party apps
The X850E runs on Android TV that has access to the Google Play Store. The Play Store has a nice selection of apps, but normal Android apps won't work unless they support Android TV.
Pro Decent picture quality
The X850E looks really good in dark scenes, thanks to its decent contrast ratio of 4500:1 and excellent black uniformity.
It can produce blacks that are 4500 times darker than the brightest white, and the black uniformity is especially good - there’s barely visible flashlighting, where edges of the screen have a light on them when displaying a black image, and the screen is evenly bright. This makes it perform really well in dark scenes.
Colors look vibrant because of the panel’s high peak brightness levels of ~350 nits for SDR & ~400 nits for HDR. With these brightness levels, it can get bright enough to fight glare. Along with its great handling of reflections, pictures will still look good in decently-lit environments without dull colors.
Pro Interface is ads-free
There are no ads on the X850E’s interface.
Pro Excellent motion interpolation capabilities
The X850E can increase the framerate of content to either 60Hz or 120Hz.
It guesses which frames are missing based on the previous and next frame, and inserts the missing frame in between them. This produces a really strong soap opera effect, where images look really smooth.
This might look weird to some people that don't like it, but the X850E can do this really well for those who enjoy it.
Pro Suitable for gaming
The X850 has a relatively low input lag of ~35ms that makes it a decent pick for gaming. Most players will feel in sync, however, it might be a little unresponsive for competitive or demanding gamers.
It’s also acceptable for HDR gaming because the input lag does not increase in HDR mode.
Pro Excellent for 24p content
The X850E is an excellent option for those who watch content from an antenna/satellite box, DVD/Blu-ray player or Apple TV. It can detect eliminate jerky playback that is common in content from these sources.
Pro Offers best value for screen size in this price bracket
The X850E has the largest screen size at 65” for the cheapest when compared to its direct competitors. Similarly-sized models from its direct competitors cost much more.
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.
Con Not suitable for group watching
The X850E has a narrow viewing angle that makes it unsuitable for watching with groups.
Its picture quality starts to deteriorate significantly when viewing from just ≥20° away from the screen's center. The colors will start degrading really quickly.
Con Might require color calibration
Some viewers might find the X850E’s white balance to be slightly off out of the box, so a brief calibration might be required if you notice it. Fortunately, all the optimal color settings are available on the internet and isn’t hard to find.
