But they also have dual DisplayPort outputs, and a USB-C output, although that can't be used simultaneously with the HDMI output. Connecting the system to the docking station allows you to easily connect multiple peripherals (mouse, keyboard, stereo speakers, external hard-drives, and high-resolution displays) without having. ![]() Note however that both docks only have a single HDMI output. The Dell Thunderbolt Dock - WD22TB4 is a device that links all your electronic devices to your system using a Thunderbolt 4 (Type-C) cable interface. The WD19TBS would be able to run dual displays up to 4K 60 Hz or triple displays up to 2560x1440. The WD19S when paired with your system would be able to run dual displays up to 1920x1200 each or a single display up to 2560x1440. There's no harm using that, but that particular aspect won't deliver any benefit to your system. The TBS is only available in 180W w/ 130W PD form, though. ![]() You don't need the 180W w/ 130W PD passthrough option because the 7490 doesn't require that much power. With a 7490, you'd be fine with the 130W w/ 90W PD version of the WD19S. If you don't need the higher-end display or Thunderbolt peripheral capabilities, or your system doesn't have Thunderbolt in the first place, then the WD19S is the better choice. The WD19TBS also allows you to connect a native Thunderbolt peripheral to the dock if you have or think you might ever want one, although Thunderbolt peripherals are admittedly somewhat rare. If your system has Thunderbolt, then the WD19TBS will be able to tap into 4x more video bandwidth than the regular WD19S that only uses USB-C, which means you can run higher-end display setups.

The difference is that the latter supports Thunderbolt 3, which was optional on the Latitude 7490. The Dell universal docking station UD22 is the first universal dock that has moved from USB 3.0 to USB 3.2 Type-C for its main connection.
