If you prioritize vibrant colors and deep blacks for immersive gaming and media consumption, the Gigabyte FO27Q3 with its QD-OLED panel will deliver a superior experience, especially with its higher refresh rate for smooth gameplay. However, if you need a larger screen and higher resolution for productivity tasks, the ViewSonic XG321UG might be a better option, though it may not offer as much gaming performance or contrast as the Gigabyte. Despite being more expensive, the ViewSonic also has better text clarity and higher brightness, which benefits daylight usage and content creation, but it might not be as suitable for HDR gaming and media due to the lack of certain features.
