Afterwards, automatic port installation is initiated on each system.

After installation is complete, it is recommended to restart the laptop/tablet.

Connecting Monitors (HDMI / DP)

Use HDMI / Thunderbolt™ 3 to connect a monitor to the docking station (for HDMI, a cable version 2.0 or higher is recommended). The monitor on the laptop/tablet may flicker during the installation of an additional monitor, which is a standard condition. The docking station supports connecting a maximum of two monitors.

Graphics Interface: 1x HDMI and Thunderbolt™ 3. Resolution:

1 monitor connected via Thunderbolt™ 3 port - resolution up to 8K 7680x4320/30Hz
8K resolution is only supported if the laptop's Thunderbolt™ connector supports DisplayPort 1.4 standard.
1 monitor connected via HDMI port - resolution up to 4K 3840x2160/60Hz

Image description: Two setups are shown. The top shows one monitor connected via Thunderbolt™ 3, displaying a graph. The bottom shows two monitors connected, one via Thunderbolt™ 3 and one via HDMI, also displaying graphs.

2 monitors connected simultaneously via 1x Thunderbolt™3 port and 1x HDMI, maximum resolution 4K 4096x2160@60Hz

Video resolution and refresh rate depend on the capabilities of the main PC/NB.

Standby / Hibernation Mode and Video Port: After waking the laptop/tablet from standby/hibernation, the primary (original) monitor is displayed. Therefore, it is recommended to use the one integrated with the laptop/tablet as the primary monitor for re-logging into the system.

Mirror Mode: On the additional monitor, the parameters of the original monitor in the system apply. This means if Mirror mode is set and the original monitor has a resolution of 1920x1080, the additional monitor will display the screen at a maximum resolution of 1920x1080, even if a higher resolution is set.

You can also easily control monitors using the keyboard shortcut "Windows" + P.

By selecting the "Gather Windows" option, you can choose settings for the respective monitor - Customized Resolution (offers user-defined resolutions), Rotation (Standard, 90°, 180°, and 270°), and Refresh Rate (if offered). Depending on the monitor used, these settings are:

Display Variant 1.

Display Variant 2.

In Customized mode, click on the selected icon; the resolution will be described below the screen (here visually 3008x1692 = 4K@30Hz).

Clamshell Mode: Working on an external monitor with the Mac lid closed is only possible when the Mac is turned on and a mouse and keyboard are connected. More information here: https://support.apple.com/cs-cz/HT201834

Most screen refresh issues on a connected monitor after Mac sleep, screen saver, restart, or power cycle can be resolved by disconnecting the Thunderbolt™ 3 docking cable from the Mac's Thunderbolt™ 3 port and reconnecting it after about 10 seconds. Then wait for all peripheral devices to connect.
