USB-C PD input. Accepts up to 100W from a compatible charger for negotiated host charging.
Create independent external desktops across three displays
DISPLAYLINK VIDEO
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
Join USB, wired network, media cards and audio
DESK CONNECTIVITY
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

- Restart or reconnect if requested by the installer.
- Connect one display and verify detection before adding the others.
- Connect a suitable PD charger if host charging is needed.
- Add Ethernet, USB, cards and audio devices one at a time.
- Arrange displays in the operating-system settings and safely eject storage before disconnecting.
Compatible devices and systems
Host and peripheral fit
Connector shape alone is not enough: the host port, operating system, cable, display and peripheral must support the required function.
Windows. Supported Windows systems can use DisplayLink and reach the stated Windows display ceiling on qualifying hardware.
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
Read before use
Check before connecting or ordering.
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.
- 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.

Model-specific data
Verified in-box information
A PD charger and display cables are not included. Current DisplayLink software should be obtained from the official source when the supplied installation media is outdated.
Questions buyers ask.
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.
