If you prioritize an immersive gaming experience with deep blacks and superior contrast, the significantly pricier Acer Predator X45 with its OLED panel is well suited for HDR gaming and media. However, if you're an enthusiastic gamer needing high responsiveness and prioritize a more balanced monitor for both gaming and productivity, the Asus PG279QM at a lower price point offers a solid performance with good color accuracy and clarity for everyday tasks. The Acer excels in pure visual quality, especially in dark environments, but the Asus is more versatile for various uses including competitive gaming. Give Feedback
