Exact model 35897
UGREEN 7-in-1 Dual-HDMI USB-C Hub for a Desk Display Setup
Model 35897 adds two HDMI outputs, four USB-A data ports and one USB-C Power Delivery input to a compatible USB-C computer. It supports one display up to 4K@30Hz or two displays up to 1080p@60Hz, with operating-system limits that matter before buying.
Product overview
Overview
What model 35897 is designed to do
UGREEN 35897 is a compact docking adapter for a host USB-C port that supports video output. Its exact seven-port map is two HDMI, one 5Gbps USB-A 3.0, three 480Mbps USB-A 2.0 and one USB-C PD charging input.
A single HDMI display is listed up to 4K@30Hz. When both HDMI ports are used, the listed maximum is 1080p@60Hz per display. Windows can use supported mirror or extended arrangements; macOS mirrors the same external image across both HDMI screens because this hub relies on MST-style dual-display behaviour that macOS does not expose as two independent external desktops.
At a glance
Key features
The corrected seven-port map
HDMI 1 + HDMI 2
Video outputs for compatible DP Alt Mode hosts. Single display up to 4K@30Hz; two displays up to 1080p@60Hz.
USB-A 3.0 × 1
One 5Gbps USB data port for storage or another higher-speed peripheral.
USB-A 2.0 × 3
Three 480Mbps USB data ports suited to keyboard, mouse, receiver, printer and lighter peripherals.
USB-C PD × 1
Charging input up to 100W from a separate charger. It does not carry data or a third display.
Dual-display output
One 4K@30Hz display or two 1080p@60Hz displays
Use one HDMI port for a display up to the listed 4K@30Hz mode, or connect both for up to 1080p@60Hz on each screen. The source must support video over its USB-C port.
- A USB-C port without DP Alt Mode produces no HDMI image.
- Use known-good HDMI cables and select supported modes.
Windows and macOS behaviour
Independent external desktops depend on the operating system
Compatible Windows computers can use mirror or extended layouts according to the host's graphics capabilities. That can provide two different external desktops where MST is supported.
- Check the exact computer's external-display limit.
- macOS does not gain two independent external desktops from this hub.
Four USB-A ports
Separate one 5Gbps port from three 480Mbps accessory ports
The port map contains one USB-A 3.0 port rated up to 5Gbps and three USB-A 2.0 ports rated up to 480Mbps.
- USB bandwidth is shared through the host connection.
- Storage speed remains below the signalling ceiling.
Power Delivery pass-through
Add a charger through the 100W USB-C PD input
Connect a separate USB-C PD charger up to 100W to power the hub and pass negotiated charging to the host. The host receives less than the charger's headline value because the hub reserves power for operation.
- Use a charger and cable rated for the required input.
- Confirm the host supports USB-C PD charging.
Real-world applications
Use scenarios
Desk setups that match this port mix
Windows dual-screen desk
Connect two 1080p displays plus keyboard, mouse and storage to a compatible DP Alt Mode Windows laptop.
Single 4K presentation
Run one display up to 4K@30Hz while using the remaining ports for accessories.
macOS mirrored output
Show the same external image on two HDMI screens, with the Mac display as a separate workspace where supported.
Peripheral expansion
Use the 5Gbps USB-A port for storage and the three USB 2.0 ports for lower-bandwidth desk accessories.
Device and system fit
Compatible devices and systems
Host USB-C requirements come first
Windows USB-C laptops
Need DisplayPort Alt Mode for HDMI and suitable system support for dual extended displays.
Mac computers
Need compatible USB-C video output; dual HDMI screens mirror each other rather than extend independently.
USB-C tablets
May support one mirrored or extended display according to the tablet; desktop-style dual output is not guaranteed.
HDMI and USB peripherals
Displays need HDMI inputs; USB devices connect through one 5Gbps and three 480Mbps USB-A ports.
Connection workflow
Setup and usability guidance
Connect power, displays and peripherals in a controlled order
- Confirm the host USB-C port supports DisplayPort Alt Mode and any required PD charging.
- Connect a suitable USB-C PD charger to the hub's PD input if host charging is needed.
- Connect the hub to the host and allow the operating system to recognise it.
- Attach one HDMI display and select a supported resolution before adding the second.
- Add the second HDMI display and choose mirror or extend according to Windows/macOS limits.
- Connect higher-speed storage to the single USB-A 3.0 port and lighter accessories to USB 2.0.
Realistic performance
Every port shares one USB-C host connection
Display capability, USB bandwidth and charging all depend on the host USB-C implementation. The hub exposes ports but cannot add protocols the host does not support.
Single display
Up to 4K@30Hz as listed, subject to host, HDMI cable and display.
Dual display
Up to 1080p@60Hz each; Windows can extend where supported, macOS mirrors the externals.
USB data
One port up to 5Gbps; three ports up to 480Mbps, with real speed lower and shared.
Host charging
100W is the input ceiling. The hub uses part of the power and the host negotiates the remainder.

- Use the 5Gbps port for storage.
- Use a suitably rated PD charger and cable.
- Eject drives before disconnection.
What not to do
- Do not expect video from an unsupported host port.
- Do not connect a data device to the charging-only PD input.
- Do not unplug storage during writes.
- Do not overload USB ports with high-power bus devices.
Safe operation
Warnings and limitations
Warning 1
The hub can become warm while driving displays, moving data and passing power; keep it uncovered and stop use if heat is abnormal.
Warning 2
Disconnect power before cleaning and keep all ports dry.
Warning 3
A failing charger or cable can cause display resets or unstable devices; test each component separately.

FAQ
Product-specific FAQ
What are the seven ports?
Two HDMI, one USB-A 3.0, three USB-A 2.0 and one USB-C PD charging input.
How many 5Gbps USB-A ports are there?
One. Model 35897 has one 5Gbps USB-A 3.0 port and three USB-A 2.0 ports rated up to 480Mbps.
Can both HDMI displays run at 4K?
No. UGREEN lists one display up to 4K@30Hz or two displays up to 1080p@60Hz each.
Can my Mac use two different external desktops?
No. The two HDMI outputs mirror the same external image on macOS.
Does it work with any USB-C port?
USB data can work on a data-capable port, but HDMI requires the host port to support DisplayPort Alt Mode.
Is the USB-C PD port also a data port?
No. It is a charging input only.
Does 100W reach the laptop?
No. 100W is the charger-input ceiling; the hub consumes power and the host negotiates a lower pass-through amount.
Which port should I use for an SSD?
Use the single USB-A 3.0 port rated up to 5Gbps.
Does it include Ethernet or a card reader?
No. Neither feature is present on model 35897.
Is a charger included?
No charger is included in the verified package statement.
