Our Verdict

Dell S2419HGF

Dell S2421H

The Dell S2419HGF is better than the Dell S2421H, but they use different panel types, each with strengths and weaknesses. The S2419HGF uses a TN panel with a faster refresh rate and a significantly faster response time. The S2419HGF also has a much better stand, with much better ergonomics. On the other hand, the S2421H has better viewing angles and much better gray uniformity.
