If you're a competitive gamer looking for high refresh rates and low response times, the Asus PG27AQN (IPS) is an excellent choice despite its higher price. However, if you're on a budget and your use primarily involves everyday productivity and casual gaming, the Dell S2721DS (IPS) offers good image clarity at a more accessible price, though with lower refresh rates and response performance. Neither option is ideal for HDR gaming or video editing, as neither monitor supports this particularly well. For photo editing, the Asus has a slight edge with better color coverage. 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."
