Our Verdict

Gigabyte AORUS FO48U OLED

Dell Alienware AW3423DW

Although the Dell Alienware AW3423DW and the Gigabyte AORUS FO48U OLED both have OLED panels, they perform a bit differently. The Dell is a QD-OLED that displays a wider range of colors and makes small highlights get brighter, so if you want the best picture quality in dark rooms, get this one. However, if you also use your monitor in a room with a few lights around, the Gigabyte is better because blacks are still perfect in dark rooms, while ambient lighting on the Dell causes the black levels to rise.
