If you prioritize an immersive gaming experience with excellent contrast and deep blacks, the AOC AG456UCZD with its larger, curved OLED screen and superior overall gaming performance could be worth the higher price. However, if you're focused on high-speed, competitive gaming and need a monitor with faster response times to minimize motion blur, the Asus PG27AQN, being more affordable, with its high refresh rate and lower response time, would be a better fit. The AOC may disappoint for text clarity and productivity, while the Asus provides a balance of gaming performance and good screen clarity for general use. 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."
