Our Verdict
LG 48 C1 OLED
Dell Alienware AW3423DW
The LG 48 C1 OLED and the Dell Alienware AW3423DW are different types of OLED displays. The LG is a small TV with a traditional OLED panel, while the Dell is an ultrawide gaming monitor that uses the new QD-OLED technology. While they each display perfect blacks in dark rooms, the LG is better in bright rooms because it has a polarizing layer that makes blacks look deep and inky even when there's a bright light on it, while the black levels are raised on the Dell. However, thanks to the quantum dot layer, the Dell displays a wider range of colors, and small highlights get brighter, resulting in a higher color volume.
