UGREEN 90325
A 12-in-1 DisplayLink dock for a three-screen Windows or Mac desk
UGREEN Revodok Pro 312 (90325) combines three DisplayLink-driven video outputs, four USB data ports, Gigabit Ethernet, SD/TF readers, audio and up to 100W PD input.
Product introduction
Overview
The dock uses DisplayLink software to provide up to three independent external displays on supported Windows and macOS computers. Its HDMI 2.1 port supports up to 8K30 on Windows, while macOS output is limited to 4K60; the second HDMI and DisplayPort support up to 4K60 on compatible setups.
Data connections include one USB-C 10Gbps, one USB-A 10Gbps and two USB-A 5Gbps ports. Gigabit Ethernet, SD and TF readers rated around 104MB/s, and a 3.5mm audio connection complete the workstation port set.
The dedicated PD input accepts up to 100W for negotiated host charging, but a charger is not included. DisplayLink software must be installed on Windows or macOS before the additional displays operate; Linux is not supported.
At a glance
Key features
Port-by-port clarity
Connections and signal roles
Three display outputs
HDMI 2.1, HDMI 2.0 and DisplayPort 1.2 support a compatible triple-display layout.
Four USB data ports
One USB-C and one USB-A support up to 10Gbps; two USB-A ports support up to 5Gbps.
Network, cards and audio
Adds Gigabit Ethernet, separate SD and TF readers, and a 3.5mm audio connection.
USB-C PD input
Accepts up to 100W from a compatible charger for negotiated host charging.
DISPLAYLINK VIDEO
Create independent external desktops across three displays
Install the current DisplayLink software before using the video outputs. Supported Windows and macOS systems can arrange three independent external screens even when native USB-C display limits are restrictive.
Windows can reach up to 8K30 through HDMI 2.1 on a compatible setup. macOS is capped at 4K60, and actual modes depend on every host, cable and display in the chain.
- DisplayLink driver required
- HDMI 2.1, HDMI 2.0 and DP 1.2
- Triple display on supported Windows and macOS
- Linux is not supported
DESK CONNECTIVITY
Join USB, wired network, media cards and audio
Two 10Gbps and two 5Gbps USB ports connect storage and peripherals, while Gigabit Ethernet supplies a wired-network path and the card slots handle SD and microSD media.
All functions share the host connection and power budget. Real speed varies with simultaneous use, and the PD input needs a separately selected charger.
- USB-C and USB-A up to 10Gbps
- Two USB-A up to 5Gbps
- SD and TF around 104MB/s
- Gigabit Ethernet and 3.5mm audio

macOS
Supported Macs can use three external DisplayLink displays, with output limited to 4K60.
USB-C hosts
Require a compatible USB data connection and permission to install DisplayLink software.
Linux
Not supported for this DisplayLink dock.

Warnings and limitations
Check before connecting or ordering
- Confirm the computer runs a supported Windows or macOS version.
- Confirm you can download, install and approve DisplayLink software.
- Do not select this dock for Linux.
- Check each monitor and cable for the target resolution and refresh rate.
- Remember that 8K30 is a Windows maximum; macOS is limited to 4K60.
- Select a compliant USB-C PD charger separately if host charging is required.
- The PD input rating does not guarantee 100W reaches the host.
- Plan display cables separately; they are not listed as included.
Warning / limitation 1
DisplayLink software may require administrator access and operating-system permissions.
Warning / limitation 2
Protected or latency-sensitive video workflows may behave differently through DisplayLink than through a native GPU output.
Warning / limitation 3
Resolution and refresh rate depend on the host, software, cable and display combination.
Warning / limitation 4
The enclosure may warm under multi-display, charging and data loads; disconnect it if heat is abnormal.
Warning / limitation 5
Removing power or storage during a write can corrupt data.

Model-specific answers
Product-specific FAQ
Is this a 12-in-1 or 13-in-1 dock?
The verified Revodok Pro 312 port map is 12-in-1; the legacy regional URL that says 13-in-1 is inconsistent.
Does it need a driver?
Yes. DisplayLink software must be installed and approved before the external display outputs work.
Can it run three independent displays on a Mac?
Yes on a supported macOS system through DisplayLink, with a maximum output of 4K60 rather than Windows' 8K ceiling.
Can Windows output 8K?
The HDMI 2.1 port supports up to 8K30 on compatible Windows hardware, cable and display.
Does it work with Linux?
No. Linux is not supported for this DisplayLink dock.
Does it charge the laptop?
It accepts up to 100W PD input and passes negotiated power to a compatible host; actual delivery is lower and host-dependent.
Is the PD charger included?
No. Select a suitable compliant USB-C PD charger and cable separately.
Which USB ports reach 10Gbps?
One downstream USB-C and one USB-A port are rated up to 10Gbps; the other two USB-A ports are up to 5Gbps.
Can both card slots be used?
The dock provides separate SD and TF readers rated around 104MB/s; performance depends on the cards and shared bandwidth.
Why is a display missing after connection?
Check that DisplayLink is installed and approved, then verify the cable, display input and operating-system display settings.
Are display cables included?
No display cables are listed in the verified package; select cables that support the required resolution and refresh rate.
