Our Verdict
LG 34GP950G-B
Dell Alienware AW3423DW
The LG 34GP950G-B and the Dell Alienware AW3423DW are both ultrawide gaming monitors with different displays. The LG is an LED-backlit monitor that gets brighter than the Dell, which has a QD-OLED display with perfect black levels. Motion handling is also better on the Dell thanks to the near-instantaneous response time, and it displays a wider range of colors with better accuracy. However, the LG has better text clarity because it uses a standard RGB layout, while the Dell has a triangular subpixel layout.
