If you're focused on competitive gaming, the Asus PG279QM offers a higher refresh rate, which ensures smoother gameplay, making it a strong choice. However, if you prefer a larger screen with higher resolution for an immersive experience in productivity tasks and media consumption, and you're willing to spend more, the Dell Alienware AW3821DW would be better suited for you. Although neither is ideal for HDR gaming and media consumption, the Asus is well-suited for digital and print photo editing due to its strong color reproduction, while the Dell offers a wider screen, which might be more appealing for multitasking during productivity work.
