If your focus is on competitive gaming with an ultra-wide field of view, the Asus PG34WCDM with its broad VRR range and strobing features offers a substantial edge. Conversely, the MSI MAG 321UPX provides better value with its higher resolution, superior color gamut, and is better suited for tasks like digital photo editing, HDR video editing, and print photo editing due to its stronger color accuracy. Both have OLED technology, meaning deep blacks and strong contrast, but the MSI's higher brightness and higher resolution will enhance media consumption and productivity. Choose Asus for a gaming-centric experience or MSI for a balance between gaming, media, and creative work. Give Feedback
