If your focus is on casual gaming and digital photo editing without spending much, the AOC 24G2SPU is a solid pick; it offers good performance for these activities at a midrange price. However, if you're into competitive gaming and require a larger screen with higher resolution, the Dell Alienware AW2721D, though premium priced, provides a very good refresh rate, better image clarity, and a higher resolution which enhances the gaming experience. Neither are the best for HDR gaming or media consumption due to their limited brightness and color volume, but the Dell's larger color gamut could be marginally better for non-professional photo editing.

"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."
