KOORUI 24E3 165Hz Gaming Monitor vs GIGABYTE M28U 28" 4K 144Hz KVM Gaming Monitor
The KOORUI 24E3 165Hz Gaming Monitor is the budget option here, while the GIGABYTE M28U 28" 4K 144Hz KVM Gaming Monitor sits firmly in the mid-range. If you’re serious about gaming in 2026, the GIGABYTE’s 4K resolution at 3840 x 2160 delivers stunning visuals that the KOORUI simply can’t match—it's a game changer. In my testing, the KOORUI provides an impressive 165Hz refresh rate, perfect for high-paced gaming, but its 1920 x 1080 resolution falls short for anyone looking for the sharpest details. Meanwhile, the GIGABYTE’s built-in KVM switch allows you to control multiple devices seamlessly, which is great if you're juggling a PC and laptop for gaming and work. The numbers make the difference clear.
