Overview
Samsung positions the QN900D as its flagship, with a Mini-LED backlight, a processor that upscales content to very high resolution and a slim Infinity Air design. Speakers use Object Tracking Sound Pro, and Alexa and Google Assistant are among the voice options.
Brightness, motion handling and sound go together in this flagship. The fastest refresh needs a compatible PC and drops to lower resolution. Native content at this resolution is scarce, so upscaling does most of the work.
Who it's for
Home theater owners who want a bright Mini-LED panel with strong audio. Shoppers on a modest setup, or who need a light set for mounting, should look at smaller models.
Pros and cons
- Mini-LED backlight with high brightness
- Strong built-in sound system
- Four HDMI ports and four USB ports
- Slim Infinity Air design
- Heavy to mount
- Highest refresh only at lower resolution
- Little native content at this resolution
- Software update support not stated
Performance notes
The Mini-LED backlight is divided into many small zones, so bright and dark parts of a scene are lit separately. The NQ8 AI Gen3 processor upscales lower resolution content using AI formulas, so results vary with the source. The fast refresh mode requires a compatible PC connection and is limited to lower resolution.
