Our Verdict
Dell Alienware AW3821DW
LG 34GP950G-B
The LG 34GP950G-B is slightly better than the Dell Alienware AW3821DW. The LG has a slightly faster refresh rate and a much faster response time, with significantly less overshoot. The Dell, on the other hand, has better ergonomics, it feels better-built, and it has better connectivity, with an additional HDMI port and two extra USB ports.
