Our Verdict
LG 42 C2 OLED
Dell Alienware AW3423DWF
The Dell Alienware AW3423DWF uses an OLED panel like the LG 42 C2 OLED, but there are differences between each display. The Dell is an ultrawide monitor with a 3440x1440 resolution and uses a QD-OLED panel. It allows it to display a wider range of colors with better luminance levels than the LG. On the other hand, the LG is a 42-inch 4k TV with HDMI 2.1 bandwidth, which is great if you want to use it for console gaming with the PS5 or Xbox Series X.
