If competitive gaming is your priority, the Acer XB323U-GX with its higher refresh rate and variable refresh rate support offers smoother gameplay, but it's not the best for HDR gaming or media consumption due to its lower peak brightness. The LG 27EP950 excels in image quality with superior color depth and contrast, making it ideal for HDR content and professional photo editing, but it's not optimized for gaming due to a lower refresh rate and lack of gaming-specific features. The LG's higher resolution is better for productivity and media, but this also comes with a higher price tag. Choose the Acer for gaming and budget-friendliness or the LG for top-tier image quality and professional use. Give Feedback
