If you're a serious gamer or a professional in creative fields needing a monitor that excels in color accuracy and HDR performance, the CoolerMaster GP27U with its higher resolution and advanced MiniLED technology might justify the higher cost. However, for casual gaming or everyday use, the Lenovo G24-20 provides a satisfactory experience at a budget-friendly price, albeit with lower resolution and less color precision.
