Our Verdict
Samsung Odyssey G9 C49G95T
Dell Alienware AW3423DWF
The Samsung Odyssey G9 C49G95T and the Dell Alienware AW3423DWF are different types of ultrawide gaming monitors. The Samsung has a wider 49-inch, 32:9 screen with more screen space for a more immersive gaming experience. The Samsung also gets brighter, making it the better choice for using it in well-lit rooms. However, the Dell comes with a QD-OLED panel that has much better overall picture quality, with deeper blacks, no blooming, and more vivid colors. Even though the Dell has a lower refresh rate, motion still looks better on the Dell because of its near-instantaneous response time, as there's almost no blur with fast-moving objects.
