If you prioritize competitive gaming and are budget-conscious, the Asus PG27AQN provides an excellent gaming experience at a lower price but falls short for HDR gaming and media consumption. The Corsair 45WQHD240, while more expensive, excels in media consumption with its OLED panel, offering superior contrast and color depth, which is great for HDR content and photo editing. However, its large 45-inch curved screen and aspect ratio, while immersive for gaming and watching films, may not be optimal for traditional productivity tasks and might cause difficulties with text clarity due to its size and screen curvature.

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."
