Our Verdict
Dell Alienware AW3423DW
LG 42 C2 OLED
The LG 42 C2 OLED and the Dell Alienware AW3423DW are different types of OLED displays. The LG is a better choice if you want to maintain the 16:9 aspect ratio and you want something for console gaming, as it supports HDMI 2.1 bandwidth. However, if you're a PC gamer, want a high refresh rate, and don't mind the ultrawide screen, the Dell is the better choice. The Dell also looks better in HDR because it displays more colors and gets brighter, but it's only better in dark rooms as it raises the black levels in bright rooms, something the LG doesn't do.
