GIGABYTE M28U 28" 4K 144Hz KVM Gaming Monitor vs Samsung Odyssey OLED G9 49" Curved Gaming Monitor
The GIGABYTE M28U 28" 4K 144Hz KVM Gaming Monitor is the mid-range option here, but its specs pack a punch for gaming. With a 144Hz refresh rate and 1ms response time, it’s designed for smooth gameplay. However, the Samsung Odyssey OLED G9 49" Curved Gaming Monitor, with its massive 32:9 aspect ratio and 240Hz refresh rate, caters to gamers looking for an immersive experience in 2026. In my testing, the GIGABYTE M28U is great for console gamers with its 4K @ 120Hz support, making it a solid pick for PS5 and Xbox Series X. The 49" G9, on the other hand, delivers an expansive view that effectively replaces dual monitors, but its 240Hz refresh rate and faster 0.03ms response time mean it’s built for serious competitive gaming enthusiasts.
