Our Verdict
MSI MPG 321URX QD-OLED
BenQ MOBIUZ EX321UX
The MSI MPG 321URX QD-OLED and the BenQ MOBIUZ EX321UX are 32-inch 4k gaming monitors. The MSI is a better option if you plan to mostly game on your monitor, as it has a higher refresh rate, much better contrast in a dark room, and far better motion handling. However, the BenQ is a better option if you plan to use your monitor for work, as it has sharper text, is far better at overcoming glare, and has no risk of burn-in.
