Our Verdict
LG 34GP83A-B
Dell Alienware AW3425DWM
The LG 34GP83A-B and the Dell Alienware AW3425DWM are both ultrawide gaming monitors, with a few differences, mainly due to their panel types. The LG has an IPS panel with wider viewing angles and less smearing with fast-moving objects, so it's a better choice for playing action games with someone next to you. However, the Dell monitor has an advantage with picture quality, as its VA panel has a higher contrast ratio for deeper blacks. The Dell is also the better choice for gaming in well-lit rooms, as it gets brighter, too.
