Our Verdict

Dell U3417W

Dell U3818DW

The Dell U3818DW is better than the Dell U3417W. The U3818DW has a larger, higher-resolution screen that allows you to see more of your project. The 2018 U3818DW has much-improved input lag, great for gaming, but it's slightly dimmer than the U3417W. The U3417W has a DisplayPort out, so it can be daisy-chained to a second monitor. The U3818DW doesn't have this feature.
