If high-refresh-rate gaming and excellent contrast are your top priorities, the AOC AG276QZD with OLED could be a superior choice, but keep in mind its relatively lower resolution and smaller size. On the other hand, the Gigabyte M28U offers a larger screen with a higher resolution that's better suited for productivity and image clarity, but its refresh rate is lower, which might not be as good for very fast-paced competitive gaming. The Gigabyte is also more budget-friendly, which may influence your decision if value for money is a concern. 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."
