If you're a serious gamer looking for the best performance with deep blacks and fast response times, and are okay with a higher cost, AOC AG276QZD would suit you well. However, if you prefer a larger screen for an immersive experience in productivity and media consumption at a more affordable price, go for the Dell S3422DWG. The AOC is superior for competitive gaming because of its high refresh rate and response time but isn't as well-rounded for other tasks. The Dell, while not as strong in gaming, offers a wider screen, good for multitasking and watching videos. Give Feedback

IGN
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."
