If you prioritize high-end gaming with vibrant colors, deep blacks, and a high contrast, the Acer X27U with its OLED panel is a superior choice for HDR gaming and media consumption, but it comes at a premium price. Conversely, if you are looking for a cost-effective option for casual or competitive gaming and general use, the Lenovo G24-20 offers a solid experience at a much lower cost. The Lenovo, however, won't match the Acer's performance in color accuracy and contrast which are important for HDR content and professional photo editing. Give Feedback
