Samsung UE55NU7090U is a modern Ultra HD (4K) TV with a resolution of 3840 × 2160 pixels. Bright, detailed picture on it looks as realistic as possible thanks to PurColour and UHD Dimming technologies, and the digital noise reduction function eliminates interference and distortion. The device is equipped with Smart TV and SmartThings App technologies. You will be able to control your TV via your smartphone. In my review, I will tell you in detail about the main parameters of the TV and compare it with another Samsung UE55NU7300U model.
Screen
The 55-inch (139 cm) LCD has an aspect ratio of 16: 9. Display resolution - 3840 × 2160 px (4K UHD, HDR), refresh rate - 100 Hz. For instance, Samsung UE55NU7300U has a similar resolution and diagonal, but the screen is curved, which immediately attracts attention. Futuristic design, looks more impressive than UE55NU7090U. Equipped with UHD Dimming technology, it is a quantum dot local dimming system. In TV, Samsung was first implemented in the 9 series models, and in 2018 it was applied in the 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 improves color and image quality on the screen. Thanks to it, the color accuracy has increased approximately 7 times, the total number of halftones in a color image. The ability to view HDR content with increased clarity and the most accurate color reproduction has been implemented. UHD delivers more accurate detail in the brightest and darkest scenes. UHD Dimming divides and processes the image in small blocks so you can see the picture with more accurate detail. Competitor Samsung UE55NU7300U has AUTO DEPTH ENHANCER technology, which automatically increases the contrast of central objects compared to the contrast of background objects. It creates an immersive immersive experience on the screen. As it turned out, this function qualitatively affects the image detail, but the described model does not have it.

The case is very thin, made in a beautiful black color.
The model is placed on 2 legs on the sides of the TV. Wall mount is provided, mount size - 200 × 200 mm, TV weight without stand is 17.3 kg. Dimensions - 123 × 71.4 × 6 cm.

Sound
The total sound power is 20 W, 2 built-in speakers of 10 W each. Dolby Digital Plus signal processing is used to create surround sound.
Functions
Smart TV is equipped with Linux-based Tizen operating system. This is a pretty good system, but with its own pitfalls. Samsung is trying to advertise it, but users have encountered a number of problems with use. The most common of them are not enough applications and games, more content is paid, and there are very few free applications. Installed applications can be turned off at any time, they are very slow. But YouTube videos can be watched without problems at any resolution without any slowdowns. The same fast surfing in the browser.
Picture-in-picture - two images are displayed simultaneously on the TV screen. The first video is displayed on the full screen, the second in the corner. You can watch a TV channel in parallel, and start, for example, a video from YouTube in the bottom right in the "window".
Video recording - it is possible to record on-air channels to a memory medium (USB drives).
Time Shift is a function that allows you to stop the broadcasting of the on-air TV program at any time, and record it in order to continue viewing from the moment of pause at another time.
SmartThings is one smart app for all Samsung smart devices. Connect, automate and control all your compatible Samsung devices in one convenient SmartThings app.
The light sensor is used to automatically change the brightness of the screen depending on the light level of the room. As a result, power consumption is reduced and the image is more comfortable for the eyes.

Verdict
Samsung UE55NU7090U is deservedly one of the sales leaders. The model implements all the necessary functions and technologies that are necessary for comfortable viewing of Ultra HD (4K) TV with a resolution of 3840 × 2160. The technique is definitely noteworthy. Price - 45,000 rubles. But not everyone can afford a TV for such money: the price is its main disadvantage. But if you prefer expensive technology, I would advise you to pay attention to UE55NU7300U... The TV has the same functionality, but it has a curved screen - this is the main feature of the model. It looks stylish, expensive, and costs 57 thousand rubles. If you cannot spend that amount, then consider Samsung UE40NU7170U with similar functions, but with a screen diagonal of 40 inches Ultra HD (4K), a resolution of 3840 × 2160 pixels for 28 thousand rubles.
