Our Verdict
Dell S2721DGF
Samsung Odyssey G55C S27CG55
The Dell S2721DGF and the Samsung Odyssey G5/G55C S27CG55 are entry-level gaming monitors, but because of their different panel types, they have a few differences. The Dell has better overall motion handling, so it's better for gaming, as fast-moving objects are sharper. The Dell is also better for co-op gaming as it has wider viewing angles, and it's the superior choice if you need to use it in a well-lit room, thanks to its higher brightness and better reflection handling. However, the Samsung is better if you need to use it in a dark room as blacks appear deeper than on the Dell.
