If you are looking to save money and mainly engage in everyday tasks such as browsing the web and office work, the Dell S2721DS is a wallet-friendly choice. However, if you require a sharper image for tasks like digital photo editing, the Gigabyte M28U with its higher resolution might be worth the extra investment. The Gigabyte also offers better performance in gaming due to a higher refresh rate and features like variable refresh rate to prevent screen tearing, making it suitable for casual and more competitive gamers. Additionally, the Gigabyte's stand adjusts for better ergonomics, but both monitors may not deliver the best experience for HDR gaming or video editing. Give Feedback

Jacob Ridley | January 2022
"Fundamentally the M28U is an impressive 4K monitor; between the resolution, refresh rate, and IPS panel, it's a great all-rounder for the step up to 4K. Even beyond PC gaming, the inclusion of a HDMI 2.1 port offers 120Hz gaming for consoles, so it's quite the multi-faceted package for its price. Gigabyte has made no major sacrifice to tick all the checkboxes with the M28U."
