Our Verdict
Samsung C34F791/CF791
Dell D3218HN
The Samsung C34F791/CF791 is somewhat better than the Dell D3218HN. The Dell has better viewing angles and is more suitable for collaborative work whereas the Samsung is larger and has a much better resolution that allows you to multitask better. The Dell D3218HN has lower input lag if you play casual video games, but the Samsung has a faster pixel response time that leaves a shorter motion blur, and faster refresh rate with FreeSync support to eliminate tearing.
