If you prioritize competitive gaming and want a monitor with a very high refresh rate, the Asus PG27AQN is an excellent choice. However, if you're looking for superior visual quality and are interested in HDR gaming and media consumption, the CoolerMaster GP27U's higher screen resolution and HDR peak brightness would serve you better. The CoolerMaster also has a better color performance, making it suitable for digital photo editing and other color-critical tasks. Expect to pay more for the CoolerMaster GP27U, but it offers greater versatility for both productivity and high-quality media experiences. Keep in mind, though, that for fast-paced gaming, the Asus might have a slight edge due to its higher refresh rate capabilities. 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."

"The Cooler Master Tempest GP27U leaves little to complain about. It delivers a stunning picture with high contrast, brightness, and vivid color. Professional-grade video processing means a superlative gaming experience. And it’s a little less expensive than the competition."
