Our Verdict
Dell Alienware AW3423DWF
Dell Alienware AW3425DWM
The Dell Alienware AW3423DWF is a higher-end ultrawide monitor than the Dell Alienware AW3425DWM. Although they both have 34-inch screens with a 3440x1440 resolution, there are some big differences between them. The AW3423DWF has a QD-OLED panel with much better picture quality, particularly in HDR, and superior motion handling. The main advantage of getting the AW3425DWM is that it gets brighter in SDR and doesn't risk burn-in with exposure to the same static elements over time, like the AW3423DWF has.
