If you prioritize a high refresh rate for competitive gaming, and you're looking for a monitor that's more budget-friendly, the Asus PG27AQN offers those features. However, the MSI MPG 491CQP with its wide color gamut, infinite contrast, and superior HDR performance is more suited for HDR gaming and media consumption, as well as tasks like digital photo editing that benefit from better image quality, despite its higher cost. Keep in mind that the MSI has a larger, ultra-wide screen which may enhance immersion but can be more demanding on your graphics hardware for gaming. If your use leans more towards productivity, the Asus' smaller, standard aspect ratio screen might be easier to integrate into different workspaces. Give Feedback

IGN
Matthew Smith | March 2023
"The Asus ROG Swift PG27AQN is a motion clarity marvel. It’s the first 27-inch 1440p 360Hz monitor on the market, and also the first to use an Ultrafast IPS display. These advancements provide outstanding motion clarity across a broad range of refresh rates. Unfortunately, the monitor’s motion clarity does nothing for its image quality, which is just ok. To be clear, it’s a very nice looking monitor in many situations. However, the monitor’s contrast ratio is rather low. And while it can reach high levels of brightness in HDR, it lacks the nuance and contrast required to look great in HDR games."
