If your priority is top-notch gaming and media experiences, the CoolerMaster GP27U with its higher resolution, superior brightness, and HDR support is a solid choice despite its premium price. It's also suitable for print photo editing thanks to its wider color gamut. On the other hand, the LG 34WQ73A, being significantly cheaper, offers a larger screen with an ultra-wide aspect ratio which can enhance productivity and immersion in games and movies, but it lacks the high refresh rate and advanced color features, making it less suitable for competitive gaming and professional photo editing.
