Supports USB-C DisplayPort Alternate Mode for Transmitting Audio/Video Signals
By connecting the detachable USB-C cable to a source device that supports USB DisplayPort Alt Mode, you can output 4K video and digital audio to a compatible monitor, television or projector without installing special software drivers.
Transmits Crystal-Clear True 4K Video and Digital Audio with 4:4:4 Color
The DisplayPort (DP) output supports true 4K resolutions up to 4096 x 2160 at 30 Hz. The HDMI output supports Ultra HD resolutions up to 3840 x 2160 at 30 Hz. The VGA output supports high-definition resolutions up to 1920 x 1200, including 1080p, at 60 Hz. This docking station also supports 4:4:4 chroma subsampling for top-level PC gaming or using your HDTV as a PC monitor.
DisplayPort SST and MST Modes Allow Connection of Multiple Displays
By connecting the detachable USB-C cable to a source that supports DisplayPort Single-Stream Transport (SST) or Multi-Stream Transport (MST) mode, you may connect up to three displays simultaneously. This allows you to display the same image on all monitors, extend your host desktop across all with different windows open on each, or combine all into one large display as a video wall. Connect multiple monitors in Extended (4K @ 30 Hz HDMI and 4K @ 30 Hz DP; 1080p HDMI and 1080p VGA; 1080p DP and 1080p VGA; or 720p HDMI, 720p DP and 720p VGA) and Mirror (4K @ 30 Hz HDMI and 4K @ 30 Hz DP; 1080p HDMI and 1080p VGA; 1080p DP and 1080p VGA; or 1080p HDMI, 1080p DP and 1080p VGA) modes. Note: macOS laptops or computers will only extend to one monitor. The others will be mirrored. Additionally, graphic limitation on the source may affect the quantity of monitors the dock can display. The source graphics card provides a limited bandwidth for each display.
3 USB 3.2 Gen 1 and 2 USB 2.0 Ports Connect Keyboards, Thumb Drives and Other Peripherals
Three USB 3.2 Gen 1 ports accept USB peripherals, such as flash drives, mice, keyboards and printers. They support fast data transfer rates up to 5 Gbps and are backward compatible with USB 2.0 and USB 1.1 devices. One also supports BC 1.2 charging with 5V 1.5A (7.5W) of power dedicated to fast-charging your mobile device. Two other ports are USB 2.0. Note: Host must support USB OTG (On-the-Go).
PD Charging Port Charges the Connected Notebook, Tablet or Other Device
The USB-C port supports Power Delivery (PD) 3.0 charging of connected PD Charging-compliant devices, such as laptops, Kindles, iPads and Android smartphones. Connect the device’s AC wall charger to the USB-C PD port, which supports power input up to 20V 5A (100W). This port, as well as the dock’s other USB-C port, can also be used for transferring data up to 5 Gbps. PD 3.0 Fast Role Swap technology ensures all data and power connections remain stable if the wall charger becomes accidentally dislodged. Note: USB-C PD port does not support Quick Charge (QC).
Accesses a Wired Gigabit Ethernet Network
The RJ45 port offers access to a Gigabit Ethernet network when Wi-Fi is unavailable or when a wired connection offers faster speeds. Connect using a UTP cable (sold separately), and enjoy true 10/100/1000 Mbps Ethernet speeds for fast data transfers.
Connects Speakers, Microphone and Other Audio Equipment
The USB-C docking station’s 3.5 mm mini stereo jack is convenient for connecting speakers, headphones or a microphone to your workstation. You can listen to music or record the latest episode of your podcast.
Allows External Memory Access
The memory card slots support Micro SD and SD/MMC cards for transferring data to and from your connected computer, laptop or tablet. You can access both slots at the same time.
Anti-Theft Lock Protects the USB-C Docking Station When You Aren’t Around
