If you're a competitive gamer looking for fast response times and high refresh rates, the ASUS PG279QM might be the preferred option, but it comes at a higher price. However, if you value a larger screen with a wider aspect ratio for an immersive experience in games and media, perhaps at the cost of some gaming performance, the Dell S3422DWG is a more cost-effective choice that also excels in productivity due to its ultrawide format. Neither monitor is ideal for true HDR content, but for color-sensitive work like digital photo editing, the ASUS has an edge with better color accuracy. Give Feedback

Whitson Gordon | August 2021
"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."
