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 technologies and SmartThings App. 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 screen has a 16: 9 aspect ratio. Display resolution - 3840 × 2160 px (4K UHD, HDR), refresh rate - 100 Hz. For example, Samsung UE55NU7300U has a similar resolution and diagonal, but the screen is curved, which immediately attracts attention. Futuristic design, looks more spectacular than the UE55NU7090U. Equipped with UHD Dimming technology - it is a local dimming system on quantum dots. Samsung TV was first implemented in models of the 9th series, and in 2018 it was also used in the 7th series. In TVs with screens on quantum dots, screen backlighting is used - these are the same LED TVs, but better materials were used. PurColor technology improves color and image quality on screen. Thanks to her, the color accuracy and the total number of halftones in a color image increased by about 7 times. 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 exciting effect of immersion in what is happening on the screen. As it turned out, this function qualitatively affects the image detail, but the described model does not have it.

Functions
Smart TV is equipped with Linux-based Tizen operating system. This is a pretty good system, but with its "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, 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 with any resolution without any slowdowns. The same fast surfing in the browser.
