The Asus PG27AQN, being less expensive, offers a strong competitive gaming experience with a high refresh rate and very good response time, making it suitable for fast-paced games. However, it has a lower contrast and brightness, and limited color performance, which makes it less ideal for HDR gaming and media consumption. The Samsung Odyssey OLED G9, while more expensive, provides exceptional contrast and color performance with a larger and wider screen, making it excellent for immersive gameplay and watching videos. It's also great for HDR content, but due to its lower pixels per inch, image clarity might not be as sharp as the Asus for productivity tasks. 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."
