With its multi-monitor capabilities, professionals, enthusiasts, and power users can benefit from using this robust, well-designed dock. It features up to 130W of power delivery for Dell systems, and 96W for non-Dell devices. The built-in 2.5GbE RJ45 keeps connectivity neat and simple while offering 2x Display Port 1.4, 1x HDMI 2.1, 1x USB-C 3.2 Gen2 multifunction Display Port 1.4 to transform your laptop into a great desktop in seconds. It can handle upto 4x 4K (3840x2160) @ 60Hz, 3x 4K (3840x2160) @ 60Hz, 2 x 6K (6144 x 3456) @ 60Hz, and 1 x 8K (7680 x 4320) @ 60Hz.

The best part is that the OS compatibility is not restricted to Windows 10 or 11 only. It can work with Ubuntu 24.04 or newer, Red Hat Enterprise Linux, macOS, and even ChromeOS.

The Dell Pro Thunderbolt 4 Smart Dock is the most reliable USB-C docking station around. It connects immediately and peripheral devices are very responsive. The available USB-C and USB-A on the front are a convenient addition. My only complaint would be that the dock could use additional ports on the back, as some users connect more peripherals then the available ports. #sweepstakes
