If you prioritize immersive gaming and media consumption with deep contrasts and vibrant colors, and are willing to invest more, the Asus PG34WCDM with its W-OLED panel is a remarkable choice, particularly with its ultra-wide screen that enhances cinematic experiences. However, for a more balanced option at a lower cost, the Dell Alienware AW2721D with its IPS panel is very capable, offering good color accuracy and a faster response time which is beneficial for competitive gaming. While the Dell's HDR performance isn't as strong, it's still a versatile monitor that excels in a variety of uses beyond gaming, such as productivity tasks. Give Feedback

"If cost isn't an issue and you want a gaming monitor that will give your content all-new life for years to come, the Alienware 27 Gaming Monitor defines the upper echelon of what gaming monitors do best today. This display does everything the HP Omen X 27 tried to do, but does it a whole lot better for just a slight bump in price. If you're choosing between the two, the Alienware is the clear winner, and that story repeats itself again and again no matter which 1440p contender we put the Alienware 27 up against."
