Our Verdict
ASUS ROG Swift PG348Q
Dell U3818DW
The Dell U3818DW is slightly better than the ASUS ROG PG348Q, but overall it depends on your usage. The ROG PG348Q is better for gaming, thanks to the faster refresh rate and G-SYNC support. The Dell U3818DW is better for office use thanks to the larger, higher-resolution screen, as well as the multitasking-oriented features, like PIP/PBP. The Dell U3818DW has slightly better dark room performance, as there is less backlight bleed and flashlighting.
