If you prioritize immersive HDR gaming and media consumption with deep blacks and vibrant colors, and don't mind a higher price, the AOC AG456UCZD with its OLED display is a solid choice. However, for fast-paced competitive gaming with a high refresh rate at a more affordable price, the Gigabyte M27Q-X offers a very good experience and also does well for everyday productivity and casual gaming. The AOC's larger screen enhances media experiences, but if detailed image and text clarity for productivity and digital photo editing are important to you, the Gigabyte may be more appealing.

"The company delivers again with the Gigabyte M27Q X, a 1440p monitor that comes equipped with just about everything you want and need from a gaming monitor. It may not be a 4K panel, but it more than makes up for its lower resolution in performance, bringing a whopping 240Hz refresh rate and a host of unusual features, including an onboard KVM and plenty of ports. It's a great performer, though low brightness levels and a so-so contrast ratio keep it short of top marks."
