If immersive gaming and top-notch image quality are priorities, the Acer Predator X45 with its OLED panel excels in contrast and color depth, making it an impressive choice for HDR gaming and media consumption. However, if your focus includes productivity or you're budget-conscious, the Gigabyte M28U offers a higher resolution for sharp text and image clarity, which can be beneficial for design or office work. Though less suited for HDR content, its performance in casual gaming and productivity tasks is strong, while costing significantly less. The Acer provides a unique gaming experience with a potential tradeoff in price and versatility. 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."
