To receive assistance from Dell support, click the "Get help now" icon on the right to start a live chat session. Share the private Dell S2721HGF Service Tag and 20 digit serial number with them.
None of the Dell D/E/G/P/S/SE/Alienware monitors have macOS support from Dell. As a consideration to macOS users, on some of them we did provide a macOS firmware update.
From the Dell Windows PC HDMI out port, test the second HDMI in port on the S2721HGF using the HDMI cable provided in the box.
