If you're a competitive gamer looking for exceptional refresh rates and smooth gameplay, the Asus XB273U F with its superior refresh rate could serve you well. However, for media consumption and productivity with a sharper image, the Sony M9 offers higher resolution at 4K, making it suitable for crisp and detailed visuals. The Sony M9 also supports immersive HDR gaming and media with its higher peak brightness in HDR. If print photo editing is part of your workflow, the Asus with its full AdobeRGB coverage is a better fit. Choose the Asus for top-tier gaming and print-ready color accuracy or the Sony for multimedia excellence and crisp 4K productivity at a lower cost. Give Feedback
