If competitive gaming is a priority and your budget allows for a premium purchase, the Acer X27U stands out with its higher peak brightness and excellent gaming performance, providing a sharp and responsive experience. However, for those who enjoy HDR gaming and media with striking visuals, the Asus PG27AQDM shines brighter in HDR, enhancing immersive gameplay and cinematic scenes. Both monitors offer fantastic color performance for photo editing, but neither is ideal for HDR video editing. If productivity tasks are frequent, consider that both have similar high-resolution screens, but neither excels in this use due to lower text quality and image clarity when compared to specialized productivity monitors.
