Our Verdict
LG 38GN950-B
Dell Alienware AW3821DW
The LG 38GN950-B and the Dell Alienware AW3821DW are very similar overall. They're both 38 inch, 21:9 IPS monitors with a 3840 x 1600 resolution. The LG is a native FreeSync model with G-SYNC compatibility, while the Dell is a native G-SYNC model with FreeSync compatibility. The LG's refresh rate can be overclocked up to 160Hz, whereas the Dell is capped at 144Hz, and it has better response times than the Dell. The LG also has a better color gamut and higher peak brightness, resulting in a better HDR experience. The LG has wider viewing angles for sharing content or playing co-op games, but its ergonomics aren't as good as the Dell's because it doesn't swivel at all.
