The Samsung DU6900 is okay for mixed usage. It's best suited for gaming or to use as a PC monitor, as it's a very responsive TV with good enough SDR brightness and reflection handling to overcome some glare from moderately lit rooms. It falters a bit for watching HDR movies, as its HDR brightness is disappointing, and its contrast is quite poor, providing a muted HDR viewing experience. The TV is also very inaccurate in SDR out of the box, so SDR content doesn't respect the content creator's intent. The TV's low-quality content smoothing is also poor, so any low-bitrate content ends up with noticeable macro-blocking. Finally, it's a sub-par choice for any wide seating arrangement due to its narrow viewing angle.
