If you prioritize high resolution for productivity and media, the Gigabyte M28U with its sharper image might be a better choice but it will cost you more. For casual gaming and digital photo editing, the Dell S2721DGF offers a good experience at a lower price. If competitive gaming is your focus, the Dell's quicker response time and higher refresh rate could benefit you. Neither monitor is ideal for HDR gaming and media, but for most other uses, your decision should hinge on whether you value resolution or gaming performance more within your budget. Give Feedback

Christian Eberle | January 2021
"The Dell S2721DGF checks all the boxes for an upper-mid priced display that can take on the best gaming monitors, and you might even be able to find it for under $500 (it's $450-$500 as of writing). The monitor's 1440p, runs at 165 Hz without overclock, has AMD FreeSync Premium Pro and G-Sync Compatibility, covers a large portion of the DCI-P3 color gamut and includes a lighting effect on the back."

"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."
