If you prioritize a higher refresh rate and are interested in competitive gaming, the Acer XB323U-GX with its speedy performance becomes a good fit. Conversely, the Gigabyte M28U's higher resolution creates a sharper image for productivity and media consumption, and it is more affordable. The Acer model has a better color gamut for tasks like digital and print photo editing. However, if a higher pixel density for detailed work and budget-friendliness are key for you, the Gigabyte monitor stands out. Neither are ideal for HDR gaming or video editing, so for standard tasks, your choice hinges on balancing price against specific gaming or professional needs. Give Feedback

PC Gamer
Jacob Ridley | January 2022
"Fundamentally the M28U is an impressive 4K monitor; between the resolution, refresh rate, and IPS panel, it's a great all-rounder for the step up to 4K. Even beyond PC gaming, the inclusion of a HDMI 2.1 port offers 120Hz gaming for consoles, so it's quite the multi-faceted package for its price. Gigabyte has made no major sacrifice to tick all the checkboxes with the M28U."
