If you're an enthusiastic gamer looking for maximum performance and don't mind a smaller screen, the Asus PG27AQN with its high refresh rate and quick response time is a solid, more budget-friendly pick. However, for a more immersive experience, especially in HDR gaming and media consumption with richer colors and deeper contrasts, the Dell Alienware AW3423DW's OLED technology and wider screen will deliver superior visuals, though at a higher cost. The Dell's curve can also enhance gaming and cinematic experiences, but it's not as suited to traditional productivity due to its ultra-wide aspect ratio. 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."
