If you value a high-resolution display with better color accuracy and are involved in tasks like HDR video editing or print photo editing, the CoolerMaster GP27U could be worth the investment despite its premium price. For competitive gamers, the high refresh rate and low response time make it a good choice, and it also excels in productivity and media consumption. However, if you are looking for a wider screen for an immersive experience at a lower cost, and if your tasks include casual gaming, productivity, and media consumption without a strict need for top-tier color accuracy, the Dell S3422DWG with its ultrawide format may serve you well and save you money.

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."
