If you prioritize high-quality HDR gaming and competitive gaming with deep blacks and vibrant colors, the Acer X27U with its W-OLED panel is a great choice despite its higher price. However, the Gigabyte M28U, with its larger screen and higher resolution, is better suited for productivity and offers good gaming performance at a lower cost. The Gigabyte's IPS panel also provides great color accuracy for digital photo editing. If you're not focused on top-tier gaming performance and are looking for a more budget-friendly option with versatile functionality, the Gigabyte M28U may be the better fit. 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."
