The UE40NU7170U is a high-tech novelty from the world brand Samsung with a screen resolution of 3840 × 2160 and support for 4K UHD, which contains 4 times more pixels than FullHD resolution of 1920 × 1080. The TV is equipped with picture quality enhancement technologies (UHD Dimming, PurColour), and with SmartThings App technology, setting up and controlling the TV is now easier and faster.
Screen
40-inch (102 cm) liquid crystal display, aspect ratio - 16: 9. Display resolution - 3840 × 2160 px (4K UHD, HDR), refresh rate - 100 Hz. UHD Dimming is a quantum dot local dimming system. Samsung first implemented in 9 series models, and in 2018 - in 7 series. In TVs with screens on quantum dots, screen backlighting is used - these are the same LED TVs, but higher quality materials were used. PurColor technology is designed to improve the quality of color reproduction on screen and images. Thanks to this technology, the accuracy of color reproduction has increased by about 7 times, the total number of halftones in a color image.

The TV case is made in charcoal black. The bezels are so thin that they visually enlarge the screen. The back of the case is also made in black with a corrugated surface, which looks quite interesting. The TV can be wall-mounted or mounted on a stand (supplied). Weight without stand 8.6 kg.

Functions
SmartTV - Samsung UE40NU7170U is equipped with Tizen operating system based on Linux. It's a pretty decent system, but it doesn't compare to Android 6.0, which is much simpler. Many free applications and games are released on its platform. The same cannot be said about Tizen - there are few applications, and even fewer free ones.
SmartThings is one smart app for all Samsung smart devices. Connect, automate and control all your compatible Samsung and SmartThings devices in one convenient app.
Steam Link - with this function you can play your favorite computer games on a big screen, have fun and forget about a small monitor that is connected to your computer.
Auto Motion Plus - this additional technology, according to the manufacturer, improves the display of dynamic scenes on the TV screen. It improves the smoothness of dynamic movement.

Verdict
The Samsung UE40NU7170U model turned out to be quite interesting - with a wide range of technologies to improve the image quality, 4K support, unlike the Samsung UE43N5000AU rival, which has the usual FullHD resolution, with interesting and useful functions - Smart TV and SmartThings - which the previous model does not have. All of these features attract the attention of a potential buyer, but there are some drawbacks. The TV has a habit of turning off by itself, and then turns on for a couple of minutes. The build quality is poor. Smart TV on the advertised Tizen platform often slows down, throws it out of applications. Price - 28 thousand rubles. In my opinion, in the presence of such disadvantages, it is overestimated.
