Our Verdict
Dell Alienware AW3423DW
ASUS ROG Swift OLED PG27AQDM
The Dell Alienware AW3423DW and the ASUS ROG Swift OLED PG27AQDM are different types of OLED displays. The Dell is an ultrawide monitor with a larger screen, and it uses extra quantum dot technology to display a wider range of colors that are brighter and more vivid than on the ASUS. However, the ASUS still gets brighter, so small highlights pop more. The ASUS also has a higher 240Hz refresh rate, which makes it ideal for competitive gamers.
