Universal docking stations deliver a world of choice and flexibility for workplace IT administrators. With that flexibility, arrives a host of features, specification and terminology to become familiar with in regards to compatibility and performance.
The Technology team at CMS we have put together a guide to help you navigate around the terminology when it comes to deciphering the various features of docking stations.
Upstream Connector Ports
Upstream Connector Ports
The upstream connector is the port that links the docking station to the laptop to host extra services like multiple displays and accessories. Current-gen universal docking stations now utilise a USB-C connection, but as you will see below, not all USB-C upstream ports are created equal.
In the world of universal docking, there have been 2 main connector standards, Thunderbolt and USB-C.
Originally developed jointly by Intel and Apple (Gen 1 and 2), Thunderbolt docking stations are only compatible with Thunderbolt specified laptops and cables to take advantage of the transfer rates offered by the respective docking station.
Thunderbolt 1 & 2 Connector: Mini DisplayPort Transfer rate: 10gbps / 20gbps respectively
Thunderbolt 3 Connector: USB-C Transfer rate: 40gbps Features: Thunderbolt 3 can present video on two 4K displays or one 5K screen, daisy-chaining of multiple USB-C devices is also supported.
Standard USB-C has been a broader less restrictive connector interface, it is incorporated into most universal docking stations and most USB-C equipped laptops.
USB-C 3.1 Gen 1 – 5Gbps
USB-C 3.1 Gen 2- 10Gbps
USB-C 3.2 Gen 1 – 5Gbps
USB-C 3.2 Gen 2 – 10Gbps
USB-C 3.2 Gen 2x2 – builds on the Gen 2 with a total of 2 transfer lanes, 20Gbps
Power Delivery (PD)
USB PD is a standard of charging that many USB-C devices are equipped with. Devices like docking stations are equipped with PD enabled USB-C ports to ensure that connected devices are given the correct amount of charge, as well as the correct direction of charge.
100W – 100W denotes the rate of charging that can be distributed by the docking station, Check your device to ensure the docking station is capable of charging it at the full rate.
In the context of docking stations, Video chipsets harness a device’s USB port to support multiple display and ethernet ports, giving devices like laptops the multi-screen capability of a desktop computer.
DisplayLink® develops hardware and software solutions to enable easy connectivity between monitors, virtual reality HMDs and computing devices over standard interfaces such as USB, Ethernet, and wireless networks.
The DL-6950 integrates a USB 3.0 device interface, DL3 codec, two DisplayPort++ (dual-mode) interfaces, two HDMI 2.0 interfaces, GbE, and audio on one SoC.
DP Alt mode
DP Alt mode
DP Alt Mode allows USB-C ports to transfer data/video via multiple interfaces, including the increasingly popular DisplayPort video interface. In the context of docking stations, this allows the use of DisplayPort connectors to be used to support additional monitor displays via the USB connection between the laptop and the docking station.
DisplayPort 1.2 supports 5K resolution at up to 30Hz, 4K at up to 75Hz, and 1080p at up to 240Hz
DisplayPort 1.3: Supports up to 4K at 120Hz or 8K at 30Hz
DisplayPort 1.4: Supports 1440p at up to 240Hz, and 4K at up to 120Hz
HDMI 1.4: Supports up to 4K (4,096 by 2,160) at 24Hz, 4K (3,840 by 2,160) at 30Hz, or 1080p at 120Hz.
HDMI 2.0: Supports up to 4K at 60Hz, and later versions (HDMI 2.0a and 2.0b) include support for HDR
HDMI 2.1: Supports up to 10K resolution at 120Hz, as well as improved HDR with dynamic metadata and enhanced Audio Return Channel (eARC)
HD 1080P – known as ‘Full HD’ a resolution of 1920 x 1080
QHD 2K – known as ‘Quad HD’, a resolution of 2560 x 1440
UHD 4K – known as ‘Ultra HD’ a resolution of 3840 x 2160
5K – a resolution of 5120 × 2880
