If you're looking for a monitor that offers high resolution for detailed images and is better for casual gaming with its higher refresh rate and variable refresh rate support, the Gigabyte M28U could be a great choice. It also yields a better experience in productivity tasks due to its conventional aspect ratio. On the other hand, the LG DualUp has an unusual aspect ratio that could be useful for specific multitasking scenarios, and it offers greater color accuracy, which is better for photo editing. However, it is not suitable for gaming due to its lower refresh rate and lack of certain gaming features. 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."
