AOC C24G1A 23.6" Curved FHD 165Hz Gaming Monitor vs LG DualUp 28MQ780-B 27.6" 16:18 Ergo Monitor
The AOC C24G1A 23.6" Curved FHD 165Hz Gaming Monitor crushes the LG DualUp 28MQ780-B 27.6" 16:18 Ergo Monitor for gaming thanks to its 165Hz refresh rate. This means smoother motion and a serious edge in competitive play, while the LG's limited 60Hz can feel sluggish during fast-paced action. In real-world use, you'll appreciate the AOC's vibrant display with a 3,000:1 contrast ratio, which delivers deep blacks and vivid colors. On the flip side, the LG's 2560 x 2880 resolution is fantastic for productivity and photo editing, but it sacrifices gaming performance. So, if gaming is your main focus in 2026, the AOC is the smarter buy here.
