If you are a competitive gamer looking for the best performance, the Asus PG27AQN would be an excellent choice, with a higher refresh rate and overall better gaming capabilities. However, if your priority is digital photo editing and everyday productivity at a more affordable price, the ViewSonic XG2431 offers great color accuracy and is suitable for these tasks. But, it won't perform as well as the Asus in high-end gaming. Neither monitor is particularly well-suited for HDR gaming or HDR video editing, so if those are critical for you, you might want to consider other options. 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."
