Hisense U7NQ is a television that uses a VA panel, key for achieving good contrast and appropriate black depth. The use of this technology translates into very vivid picture quality when watching content in a dark room, where blacks acquire the right saturation and resemble deep tar rather than faded ash. Moreover, the television features Mini LED backlighting, which in the tested 65-inch variant offers an impressive number of 713 local dimming zones. Naturally, smaller sizes will have fewer zones, and larger ones more, positively affecting the overall contrast.
In very favorable conditions, the television achieves a contrast level of around 40,000:1. The local dimming technology handles managing bright and dark areas of the image exceptionally well, ensuring that the television faithfully reproduces details in complex scenes. Despite the large number of zones, there can be contrast issues in particularly demanding scenes where small, bright elements are set against a dark background. Sometimes the television may dim these elements too much, causing a loss of brightness, while at other times it may overly brighten them, leading to a halo effect—glows of light surrounding objects. This effect can be noticeable, for example, in a scene from the movie Sicario 2, where bright glows around the titles can be bothersome.
Nevertheless, the use of Mini LED technology with local dimming results in significantly better overall picture quality than televisions without this technology. The effect is particularly noticeable when watching movies in a dark room—blacks are deeper, and contrast is more pronounced, allowing you to fully appreciate the details hidden in dark shots.
Samsung QN95D is a television that certainly catches the eye thanks to its use of a VA panel and innovative Mini LED backlighting. This model stands out with an impressive count of 1344 local dimming zones, providing an exceptional level of contrast and depth of black. It's worth noting that the number of backlighting zones can vary depending on the screen size — in larger models, these zones naturally increase, allowing for even better performance in terms of contrast and black levels. Mini LED, with smaller diodes, allows for more precise backlight control, significantly enhancing the quality of the displayed image. The tested 55-inch model excels at reproducing details, and its ability to adjust brightness in different parts of the screen results in a phenomenal visual effect. During our tests, Samsung QN95D on the test pattern from the film "Oblivion" surprised us with results that could compete with OLED televisions, offering nearly reference-level contrast. However, how does the television perform in more challenging conditions? In more demanding scenes, the local dimming algorithm may exhibit certain imperfections. In some cases, small bright elements on a dark background may lose a lot of brightness, which we noticed during tests with the Pioneer Kuro test disc. Additionally, when we take a closer look (e.g., a scene from the film Sicario 2), certain flaws become apparent. The television sometimes struggles with brightness optimisation — in some scenes, it dims elements too much, while in others, it brightens the screen too intensely. These phenomena can be noticeable enough to draw the viewer's attention, especially in demanding night scenes. However, if we do not pay too much attention to the mentioned imperfections, Samsung QN95D proves to be one of the best choices in terms of black depth among displays with MiniLED technology.
