Our Verdict
Dell Alienware AW3423DW
LG 45GR95QE-B
The LG 45GR95QE-B and the Dell Alienware AW3423DW are both fantastic ultrawide OLED gaming monitors, but they have a few differences. The Dell delivers better overall picture quality thanks to its QD-OLED panel that displays brighter highlights. It also has a smaller 34-inch screen and better image clarity, thanks to its increased pixel density. However, the LG has a higher 240Hz refresh rate, making it ideal for playing games at a high frame rate. They each have different types of VRR support, as the Dell monitor's native G-SYNC support is better for NVIDIA graphics cards, while the native FreeSync support on the LG is better if you have an AMD graphics card.
