mouse, keyboard or flash drive, without DisplayLink drivers installed on
the host PC or laptop running Windows.

Installation
1. Connect the host computer or laptop to the U442-DOCK21-B
using the included USB-C to C cable. Use the USB-A to C
adapter if necessary.
Note: Your source device will only charge when using a USB-C to C
cable.
2. Connect a DisplayPort- or HDMI-compliant display to Video
Port 1 with a user-supplied cable, such as Tripp Lite’s
P580-Series DisplayPort cables or Tripp Lite’s P569-Series
HDMI cables.
Note: Only one display can be connected to each Video Port. If two
displays are connected, DisplayPort will be displayed as the default.
3. Repeat Step 2 for Video Port 2.
Notes:
Depending on the display used, TVs connected to the HDMI ports will
only support maximum resolutions of 3840 x 2160 @ 30 Hz.
5K resolution is achieved by connecting the two DisplayPort output
video ports to one display simultaneously. When the DisplayPort
video ports are connected to their own displays, they will support
resolutions up to 4096 x 2160 @ 60 Hz.
4. Connect to a wired Gigabit LAN using Tripp Lite’s N201-Series
Cat6 Cable (sold separately) if Wi-Fi signals are weak or
