Samsung QE77S85HAEXXH 77" 4K OLED Smart TV, 100Hz, Tizen

The heart of this Samsung television is its OLED panel. Because each pixel produces its own light, an OLED screen can switch individual pixels off entirely, which is why this technology is known for deep black levels and strong contrast. Dark film scenes, night-time sports broadcasts and moody series keep their detail without the greyish haze typical of backlit screens, making the 77-inch picture look striking in both bright and dimmed living rooms.

With a resolution of 3840 x 2160 pixels spread across a 77-inch diagonal, the QE77S85HAEXXH delivers four times the pixel count of Full HD. On a screen this size, that extra resolution keeps text, faces and textures sharp, even when you sit relatively close. The standard 16:9 aspect ratio matches most TV broadcasts, streaming content and games, so the picture fills the screen without black bars in everyday viewing.

HDR support lets the TV display content mastered in high dynamic range, which carries more information about brightness and colour than standard video. Combined with the contrast of the OLED panel, HDR films and series can show bright highlights such as sunlight or reflections next to deep shadows in the same frame. This makes HDR-capable streaming services and discs a natural match for this 4K OLED TV.

The panel refreshes at 100Hz, double the rate of a basic 50Hz screen. A higher refresh rate helps fast-moving content such as football, motorsport and action films look smoother, with less visible judder during camera pans. For console gaming, a 100Hz panel can also make on-screen movement feel more fluid, although the manufacturer does not list specific gaming features in the specifications provided.

This Samsung smart TV runs on the Tizen operating system, Samsung's own platform for its televisions. Tizen gives you access to streaming apps and online content directly on the TV, so you do not need a separate media player for everyday viewing. Having broadcast channels and apps in one interface keeps navigation simple for the whole household and makes the large OLED screen a central entertainment hub.

The QE77S85HAEXXH has a flat screen in a black finish, a clean look that blends easily into most living rooms and home cinema setups. A flat panel is also practical for positioning, giving a consistent picture to viewers sitting across a wide sofa. The neutral black colour keeps attention on the image rather than the frame when the TV is on, and remains discreet when it is switched off.

This model is aimed at viewers who want a large, high-contrast screen for films, series and sport, and who value smooth motion and HDR content. Its 77-inch size suits spacious living rooms and dedicated media rooms where seating is further from the screen. Households that stream regularly will appreciate the built-in Tizen platform, while film fans can make the most of the OLED panel and 4K resolution.
