Our Verdict
Dell S3222DGM
Samsung Odyssey G55C S27CG55
The Samsung Odyssey G55C S27CG55 and the Dell S3222DGM are entry-level 1440p gaming monitors with a few differences, including the screen size. While they each have a curved screen, the curve on the Samsung is more aggressive, which isn't ideal if you aren't used to using a curved screen. The Dell also has a more ergonomic stand, making placing it in an ideal position easier. On the other hand, the Samsung is the better choice for HDR gaming, as the Dell doesn't support HDR at all.
