The Samsung QN900D is very good for mixed usage. It's very good when you have lights on in your room since it's very bright in SDR and easily overcomes glare from indirect lighting. It also does an adequate job of lessening the intensity of direct reflections. It looks very good in a dark room, too, with very deep blacks and minimal blooming around highlights. Highlights and colors in HDR content are punchy, leading to an impactful HDR experience whether you're watching shows, movies, or playing games. Speaking of gaming, this is a fully-featured gaming TV, although it's held back by its lack of clarity in fast motion. Finally, its viewing angle is okay if you're watching from a slight angle, but the image doesn't hold up well in wide seating arrangements.
