The Asus PG34WCDM with W-OLED offers a higher refresh rate for a smoother gaming experience and brighter screen for HDR content, making it better for competitive gaming and HDR media. Meanwhile, the Dell Alienware AW3423DW with QD-OLED has superior color quality and a high contrast, which is excellent for productivity and media consumption. The Asus is more expensive and might not justify the cost if color accuracy and contrast are your priorities. However, if you prioritize a higher refresh rate for gaming and brighter HDR performance, the Asus could be worth the extra investment. Both monitors have OLED technology, which means both will deliver deep blacks and vibrant colors, so choose based on whether gaming performance or cost and color accuracy matter more to you.
