If you prioritize a wide, immersive display and exceptional contrast for vibrant HDR gaming and media consumption, the Acer Predator X45 may be the better choice, with its OLED panel offering deep blacks and high peak brightness. However, it's less suited for productivity due to potential burn-in risks and may not offer the sharpest text quality. If competitive gaming is your focus and you want a fast, responsive experience with minimal ghosting and high refresh rates, the Asus PG27AQN would be a better fit, especially if you're also doing photo editing. It's also less expensive but won't deliver the same level of contrast and HDR performance as the Acer. 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."
