Our Verdict

Dell Alienware AW3420DW

Dell Alienware AW3423DW

The Dell Alienware AW3423DW replaces the Dell Alienware AW3420DW and improves it in many ways. The AW3423DW has a QD-OLED panel with much better dark room performance than the previous version, and it supports HDR, which the AW3420DW doesn't. The AW3423DW also has a higher refresh rate and better motion handling. The main advantage of the AW3420DW is that it has a different subpixel structure, resulting in better text clarity.
