If competitive gaming is your priority, the Asus PG27AQN with its higher refresh rate and better response times would serve you well. However, if you're looking for a more immersive experience for media consumption or casual gaming and don't mind a larger, ultrawide screen, the LG 34GN850B offers a wider display at a less expensive price point. Neither monitor is ideal for HDR gaming and media, or professional color work like digital photo and HDR video editing. The Asus might be overkill for casual use, and the LG will provide a broader canvas for multitasking but isn't optimized for the rigors of competitive gaming. Give Feedback

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."

"Mid-range 3440 x 1440 144Hz VA monitors are ~$500 to $600 these days. You are getting a much better product for the higher price of the LG, with faster response times and better colors (outside of the contrast ratio), but this is definitely a monitor that is reserved for those that want the best of the best and are willing to pay for it."
