If competitive gaming is your top priority, the Acer X27U with its higher refresh rate could give you an edge due to smoother motion. However, the Samsung Odyssey OLED G8's wider screen and aspect ratio offer a more immersive experience for media consumption, though it has a lower refresh rate. For digital photo editing, both are excellent, but the Samsung has a slight edge in color accuracy. If HDR video editing is critical for you, neither is ideal. The Samsung's glossy finish can make colors pop, but in a bright room, you might prefer the Acer's matte finish to reduce glare. Give Feedback
