Our Verdict
Dell S3422DWG
LG 34GN850-B
The LG 34GN850-B and the Dell S3422DWG are both ultrawide gaming monitors, but there are a few differences due to their panel types. The LG has an IPS panel with much better motion handling and an overclock feature for a slightly higher 160Hz refresh rate. The LG also delivers a more realistic image thanks to its better accuracy before calibration. On the other hand, the Dell gets brighter in HDR for a more vivid image, and it's also the better choice for dark room gaming as it delivers deeper blacks.
