Our Verdict
Samsung Odyssey G9
Dell Alienware AW3821DW
The Samsung Odyssey G9 and the Dell AW3821DW are two great gaming monitors, but with different features. The Dell has an IPS panel with wide viewing angles, making it easier to share your screen for co-op gaming. It also has native G-SYNC support and a quicker response time at its max refresh rate. The Samsung has a VA panel with a better contrast ratio, so it can display deeper blacks. It has a higher 240Hz refresh rate and native FreeSync support. Also, it has a much wider 49-inch screen and 5120x1440 resolution, making it a better choice for atmospheric gaming. Choosing one over the other really comes down to personal gaming preferences.
