If you prioritize an immersive experience with a larger, ultrawide screen for gaming or productivity, the Asus PG34WCDM with its higher brightness might be worth the extra cost. However, if you're looking for excellent image quality at a lower price, the Cooler Master GZ2711 offers similar color performance and is also well-suited for gaming and creative work. Both monitors offer rich colors and deep blacks due to their OLED technology, but the larger screen and higher HDR brightness of the Asus could enhance HDR gaming and media consumption, while the Cooler Master provides a more budget-friendly option with only a modest sacrifice in screen real estate and brightness.
