If you're gaming, the GIGABYTE M28U 28" 4K 144Hz KVM Gaming Monitor is the premium option. With a stunning 3840 x 2160 resolution and a blazing 144Hz refresh rate, it delivers an incredibly smooth experience. Meanwhile, the ASUS ZenScreen MB16ACE 15.6" FHD Portable Monitor is lighter at just 25.04 oz, making it a great travel companion for those on the go.
