If you prioritize high-resolution and detailed imagery for productivity or media consumption, the Gigabyte M28U, with its 4K resolution, is a solid choice. It's also suitable for casual gaming, thanks to its decent refresh rate and response time. However, for those interested in an immersive experience with a wider field of view for gaming and better image clarity, the LG 34GN850B with its ultrawide display may be a better fit despite its slightly higher cost. Be aware, though, that its lower resolution might not be as well-suited for tasks that benefit from sharper text and finer detail. Neither monitor is ideal if your main focus is competitive gaming due to the fair response times and refresh rates when compared to specialized gaming monitors. 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."

"Mid-range 3440 x 1440 144Hz VA monitors are ~$500 to $600 these days. You are getting a much better product for the higher price of the LG, with faster response times and better colors (outside of the contrast ratio), but this is definitely a monitor that is reserved for those that want the best of the best and are willing to pay for it."
