This 40-inch 5K2K (5120×2160) curved Thunderbolt hub display is built around a single 140W Thunderbolt 4 upstream port that carries video, 10Gbps data, and enough power to charge most laptops over one cable. A second Thunderbolt 4 port (15W) lets you daisy-chain a second monitor. Note that the standalone DisplayPort here is version 1.4 with DSC, not DP 2.1, and the HDMI input is a single full-bandwidth HDMI 2.1 port. A built-in 2.5G Ethernet jack feeds your laptop a wired connection through the same Thunderbolt cable.
Dell’s 40-inch 5K2K curved monitor with 140W Thunderbolt 4, daisy-chain TB4 out, HDMI 2.1, DisplayPort 1.4, and 2.5G Ethernet.
