Our Verdict
LG 34GK950F-B
Dell Alienware AW3420DW
The LG 34GK950F-B is better than the Dell Alienware AW3420DW in most uses. The LG has a higher refresh rate, a significantly higher peak brightness, as well as much better viewing angles. Also, it has better out-of-the-box color accuracy and gradient performance, but the Dell has a much better black uniformity and better gray uniformity.
