Our Verdict
Dell Alienware AW3423DWF
Samsung Odyssey Neo G9/G95NA S49AG95
The Dell Alienware AW3423DWF and the Samsung Odyssey Neo G9/G95NA S49AG95 are both fantastic ultrawide gaming monitors with a few differences. The Samsung is a super ultrawide display with an even bigger 49-inch screen compared to the Dell. They also use different panel technologies as the Samsung gets brighter thanks to its Mini LED backlighting, while the Dell displays perfect blacks due to its QD-OLED panel. Lastly, the Samsung has a higher 240Hz refresh rate, which you can use for gaming at a high frame rate.
