Our Verdict
Samsung C34F791/CF791
BenQ EW3270U
The BenQ EW3270U is significantly better than the Samsung C34F791/CF791. The BenQ EW3270U has better resolution, can display more detail on its screen, and supports HDR content. The EW3270U also has lower input lag and more uniform blacks. The Samsung, on the other hand, has a slightly faster pixel response time that leaves a smaller motion blur, and much better ergonomics to help you position it to your liking.
