Our Verdict

LG 34GP83A-B

Dell Alienware AW3821DW

The LG 34GP83A-B and the Dell Alienware AW3821DW are very similar overall. The LG has slightly better gaming performance because it has a higher refresh rate and better response times. However, the Dell delivers a better HDR experience due to its wider color gamut and higher peak brightness. The biggest difference between them is that the LG is compatible with FreeSync and G-SYNC, while the Dell is a native G-SYNC monitor with FreeSync compatibility. The Dell has a bigger screen and a higher resolution, but it comes out to roughly the same pixel density as the LG.
