If you prioritize a larger screen and higher resolution for tasks like photo editing and watching high-definition content, the MSI MPG 321URX with its QD-OLED panel excels, particularly in HDR video editing and color accuracy. It's also good for gaming due to its wide color gamut and low response time. However, if you're more interested in competitive gaming and need the highest refresh rates with exceptional response time, then the Acer X27U with W-OLED technology is a stronger choice, despite it not performing as well for tasks requiring high color fidelity or for watching HDR content due to its lower screen resolution. Both are premium monitors, so your decision should hinge on whether gaming performance or picture quality for productivity and media consumption is more important to you. Give Feedback
