If you're looking for a monitor with excellent gaming performance, both the Asus PG27AQDM (W-OLED) and the Dell Alienware AW3423DW (QD-OLED) deliver, yet the Dell offers a wider screen and a slightly better overall gaming experience with a more immersive aspect ratio suited for gaming and media consumption. On the other hand, if budget is a concern and you value a higher refresh rate for smoother visuals, the Asus could be a better pick even though its slightly smaller screen and narrower aspect ratio might be less immersive for gaming and movies. Both have excellent color accuracy for tasks like digital photo editing. The Dell's glossy screen can provide vivid images, but might have reflections in well-lit rooms, whereas the Asus's matte screen handles reflections better but at the expense of some image clarity.
