The Samsung Q70C is a decent TV overall, although it's best in situations where its fantastic input lag can be put to good use, like when gaming or when using the TV as a PC monitor. It's also not a great TV if you want to watch it with friends in a wide seating area, as its viewing angle is sub-par. Otherwise, its SDR brightness is very good, and its reflection handling is decent, so it can easily handle rooms with a few lights or windows when watching SDR content, like sports or TV shows. Its HDR brightness is adequate; good enough for dark rooms but not good enough to make HDR highlights pop in movies or games. Its response time is good, so fast-moving objects in sports, movies, or games have a little blur but nothing too noticeable.
