GIGABYTE M28U 28" 4K 144Hz KVM Gaming Monitor vs ASUS ZenScreen MB16ACE 15.6" FHD Portable Monitor
In the battle between the GIGABYTE M28U 28" 4K 144Hz KVM Gaming Monitor and ASUS ZenScreen MB16ACE 15.6" FHD Portable Monitor, the GIGABYTE M28U comes out ahead for serious gamers. It boasts a remarkable 144Hz refresh rate, delivering twice the smoothness compared to the ASUS's 60Hz, making it perfect for fast-paced gaming in 2026. The GIGABYTE model, despite being a premium option, features advanced specs like HDMI 2.1 ports for 4K at 120Hz, while the ASUS ZenScreen is an ultra-portable choice weighing just 1.57 lbs. But with a brightness of only 220 nits, the ASUS can struggle in bright environments, while the GIGABYTE's 300 nits offer a much more vibrant experience indoors and out.
