Resolution, topology and host limits
Display planning
gallery chart: with a DP 1.4 host, macOS supports single 4K60 or dual 4K60 mirrored externals; Windows supports single 4K60 or dual 4K30.
With a DP 1.2 host, macOS supports single 4K30 or dual 4K30 mirrored externals; Windows supports single 4K30 or dual 1080p60.
On macOS the laptop may show one desktop while both external HDMI displays show the same external desktop. This is not two independent external workspaces.
On compatible Windows systems, MST can provide independent extended desktops. No DisplayLink software is used.
USB, card and network performance
Shared resources
USB 3.0 ports are up to 5Gbps and the USB 2.0 port is up to 480Mbps.
Gigabit Ethernet needs a Gigabit router/switch and suitable Ethernet cable.

Setup and usability guidance
Practical connection order
- Confirm this SKU on the product or invoice.
- Check the host port for required video, data and charging roles.
- Place the hub/dock on a stable, open surface; place stand models before loading a device.
- Connect required external power before the host when the model requires or benefits from it.
- Connect the host using the marked upstream lead or port.
- Attach one display first and confirm a stable picture before adding others.
- Add Ethernet, storage, cards and low-speed peripherals one group at a time.
- Configure display arrangement, resolution and refresh in the operating system.
- Eject storage/cards before unplugging; disconnect high-power accessories before packing.
Compatible devices and systems
Host and peripheral fit
Windows DP Alt Mode hosts with MST for independent screens. Compatibility means only the functions exposed by the specific host port and operating system; connector shape is not enough.
MacBook DP Alt Mode hosts with mirrored external screens. Compatibility means only the functions exposed by the specific host port and operating system; connector shape is not enough.
Thunderbolt 3/4 or USB4 hosts exposing compatible native video. Compatibility means only the functions exposed by the specific host port and operating system; connector shape is not enough.
USB-C laptops/tablets for the functions their ports actually support. Compatibility means only the functions exposed by the specific host port and operating system; connector shape is not enough.
What this product does
Function scope
- Adds two HDMI connections and clear DP1.4/DP1.2 modes
- Adds Gigabit Ethernet and three USB-A data ports
- Reads SD and TF/microSD cards
- Accepts up to 60W PD input
What this product does not do
Boundaries
- It does not provide independent dual external desktops on macOS.
- It does not use DisplayLink.
- It does not have USB-C data, audio, DisplayPort or VGA.
- It cannot exceed the host's DP lane and GPU limits.
What to do
Recommended practice
- Match the SKU before ordering.
- Use qualified display, Ethernet and USB-C cables.
- Connect external power when specified or when bus-powered storage is unstable.
- Keep firmware, OS and relevant drivers current.
- Test the simplest connection first, then add devices.
What not to do
Avoid common mistakes
- Do not assume every USB-C port carries video, data and power.
- Do not add individual port maxima to claim an aggregate throughput.
- Do not cover the hub or place it on heat-trapping fabric.
- Do not remove storage/cards during writes.
- Do not force connectors, stand hinges or devices that do not fit.
Warnings and limitations
Read before use
Warning / limitation 1. Check the host DP version before promising 4K or dual-screen refresh rates.
Warning / limitation 2.
Warning / limitation 3. Do not use the PD input for storage or display.
Warning / limitation 4. Keep Ethernet, display and storage expectations below their individual maxima when everything is active.

Model-specific data
Power path
The PD port accepts up to 60W from a compatible USB-C charger.
Host charging will be lower than charger input because the dock needs operating power; host-output wattage is not independently stated in the gallery.
The PD port is input-only and cannot transfer files or connect a USB-C display.
Questions buyers ask.
What model is this?
This guide is for UGREEN 90119 only. Similar UGREEN hubs and docks can use different video, data and charging controllers.
What must my USB-C host support?
Use a host that supports the connection and operating-system capabilities stated in this model guide.
Can every port reach its maximum at the same time?
No. Displays, USB storage, cards and Ethernet share the upstream host link and available power. Individual port labels are ceilings, not simultaneous aggregate guarantees.
Will it charge my laptop or handheld?
The PD port accepts up to 60W from a compatible USB-C charger. Host charging will be lower than charger input because the dock needs operating power; host-output wattage is not independently stated in the gallery.
Is the wall charger included?
No wall charger is listed in the base package unless your retailer explicitly sells a charger bundle.
Does it support an external display?
gallery chart: with a DP 1.4 host, macOS supports single 4K60 or dual 4K60 mirrored externals; Windows supports single 4K60 or dual 4K30. With a DP 1.2 host, macOS supports single 4K30 or dual 4K30 mirrored externals; Windows supports single 4K30 or dual 1080p60.
Can I use it with a Mac?
MacBook DP Alt Mode hosts with mirrored external screens
Is driver installation required?
The native USB/DP Alt Mode functions are designed to be plug-and-play. Keep the operating system, GPU, USB/Thunderbolt and network drivers current. No DisplayLink claim is made unless explicitly stated.
Is it normal for the hub to become warm?
Some warmth is normal when converting video, network, data and power in a compact enclosure. Keep it uncovered and disconnect it if heat becomes abnormal or operation unstable.
What should I check if a display is blank?
Confirm DP Alt Mode, reconnect power where required, use a qualified display cable, select the correct monitor input, lower resolution/refresh, and update host graphics/USB drivers.
Can I disconnect it while copying files?
Stop transfers and safely eject storage or cards first. Removing the hub during a write can corrupt open files or the filesystem.
