If you're a competitive gamer looking for the highest performance with outstanding motion clarity and are willing to invest more, the Acer X27U with its superior response time and higher refresh rate is an excellent choice; however, it may not be ideal for productivity or media consumption due to its smaller screen and aspect ratio. On the other hand, the Gigabyte M34WQ offers a larger screen and wider aspect ratio that can boost productivity and immersion in media at a more affordable price, but it won't match the Acer in gaming performance due to its lower response time and refresh rate. Choose the Acer if gaming is your priority and budget is less of a concern, or opt for the Gigabyte if you seek a balance between work, casual gaming, and media experiences without spending as much.

Display Ninja
Rob Shafer | November 2023
"If you want a 34″ 3440×1440 ultrawide gaming monitor with a fast response time speed, smooth VRR performance, vibrant colors and crisp details, the Gigabyte M34WQ is one of the best options below $450. Additionally, it has an ergonomic stand, rich connectivity options and plenty of extra features, such as a built-in KVM switch. Some users might not be pleased by its flat screen, but at a certain viewing distance, it feels completely natural."
