If you prioritize the absolute best picture quality and gaming experience, and are willing to invest more, the Asus monitor with its OLED display will provide superior contrast, brightness, and response times, which are essential for HDR gaming and media consumption. However, its productivity performance is not on par with its gaming capabilities. On the other hand, the Dell monitor offers a wider screen ideal for multitasking and productivity tasks, and while it has a decent refresh rate and color accuracy for casual gaming, it might not provide the same level of immersion in HDR content as the Asus. Additionally, the Dell monitor is easier on the wallet. Consider what you value most: peak gaming and media quality or a cost-effective solution that balances productivity with adequate gaming and media performance. Give Feedback

"It’s hard to find any fault with the Asus ROG Swift PG27AQDM. Yes it’s expensive, but it’s incredibly good. With a stunning image and next-level video performance, it’s one of the very best gaming monitors I’ve ever reviewed."

"The Dell S3422DWG is, overall, a great monitor that delivers on most of its promises, providing a sharp ultrawide experience with smooth motion. It is, however, not as great of a value proposition, costing a bit too much compared to similar competitors."
