If you prioritize the ultimate contrast and vibrant colors for HDR gaming and media, the Acer X27U with its OLED panel excels, especially in dimly lit environments. However, keep in mind it may not be the best choice for bright rooms or productivity tasks due to its fair brightness and text clarity. The Asus PG27AQN, while less expensive, offers a higher refresh rate and very good response times, making it a superior choice for competitive gaming. It also performs well in productivity, with good text quality and image clarity, but it doesn't support HDR gaming and won't deliver the deep blacks and contrast that the Acer can. 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."
