BenQ's MA270S and MA320UG are Mac-focused monitors built around a single tradeoff: the MA270S delivers 27-inch 5K Retina-level sharpness, while the MA320UG gives you 32 inches at 4K with 120Hz refresh rate. The reviewer spent months using both simultaneously with an M5 MacBook Pro, which makes this a direct head-to-head with real daily workflow data behind it.
The core question the video answers is whether resolution or refresh rate matters more for your specific use case. Text clarity and pixel density dominate at 5K. Smooth scrolling, video editing timelines, and motion-heavy work favor 120Hz. The dual-monitor setup section starting at 4:40 is worth watching in full because it shows how the two displays complement rather than compete with each other in practice.
Both monitors sit in the premium external display tier targeting MacBook Pro, Mac Studio, and Mac mini users. The MA320UG lists on Amazon at the top of the product links, suggesting it carries the higher price point. If you are choosing one external monitor and cannot audition both, this review makes the decision criteria explicit rather than leaving you to guess.
