Your needs, this model
Does it fit your priorities?
Can a DP1.4 Windows host use three Full HD screens at 60Hz?
The original table allows that arrangement, subject to the GPU display limit and possible disabling of the internal panel.
Explore this need in the finder →Can a DP1.2 host meet that same three-screen Full HD60 requirement?
No. Its triple-display table limits DP1.2 to 1600×900 at 60Hz.
Explore this need in the finder →Can an Intel Mac use three independent external desktops?
No. The guide explains one extended Mac desktop repeated on the other dock outputs.
Explore this need in the finder →The WAVLINK UMD502 is an earlier USB-C dock whose original guide documents a useful set of Windows multi-screen arrangements. It has two HDMI outputs and one full-size DisplayPort, with different limits for DisplayPort 1.2 and 1.4 hosts. This review is for the hardware labelled WL-UMD502. The old store address now leads to a different UMD302, so that current page is not evidence for this model’s ports or power.
Choose the simultaneous mode, not a socket maximum
The original guide gives HDMI 1 a single-screen maximum of 4K30. HDMI 2 and DisplayPort can reach 4K60 with a DisplayPort 1.4 computer, or 4K30 with DisplayPort 1.2. Those individual ceilings are not a promise of three simultaneous 4K displays. The guide’s separate dual- and triple-display tables define the actual combined arrangements.
For Windows, the accepted dual-screen modes use 1920 by 1080 at 60Hz, with either both HDMI outputs or an HDMI-plus DisplayPort combination. For three external screens, a DisplayPort 1.4 host supports three 1920 by 1080 displays at 60Hz. The DisplayPort 1.2 triple arrangement is limited to 1600 by 900 at 60Hz. A requirement for three Full HD screens therefore needs the higher documented host route.
The computer’s graphics engine must also support the total active display count. The original troubleshooting instructions show disconnecting the laptop’s internal panel in Windows display settings before enabling a third external monitor when the system reaches its limit. That is a specific possible operating requirement, not evidence that every USB-C laptop can keep its own panel active alongside three external screens.
Mac outputs repeat one external desktop
The UMD502 uses native MST for its Windows expansion. Its guide explicitly says that macOS can extend one external desktop while the other dock outputs copy it. Three connected monitors consequently do not become three separately arranged Mac workspaces. The presence of several sockets does not bypass the computer’s supported display path.
The original compatibility line names Microsoft Windows and Mac OS X without exact Apple Silicon chips. This review retains an Intel Mac historical route and does not invent a new chip-specific configuration. A buyer needing several independent Mac screens should choose a dock with a documented arrangement for the actual chip, any necessary software and the intended lid condition.
USB devices, cards and network
The original guide describes USB 3.0 and USB 2.0 data functions, plus SD andmicro SD reading,Gigabit Ethernet and an audio connection. In the accepted manual edition, the per-generation USB socket counts are not settled clearly enough to create a fast-port-count guarantee. If a particular number of 5Gbps ports is essential, obtain the exact hardware port map or choose a better-documented data arrangement.
The network ceiling is 1000Mbps, which is a link capability rather than a promised internet-download rate. Both card formats are supported, but simultaneous reading of the two slots is not established. The guide also excludes Apple SuperDrive and Nintendo from its USB-A compatibility and discourages tablet charging through those peripheral ports.
Power has its own allocation
The guide explicitly gives a maximum 60W PD output to the laptop. Its separate 87W wording is not promoted into a higher net host-charging figure. The package lists the dock and quick start guide, so a suitable external charger remains necessary for a powered setup. The laptop must accept USB-C charging and its workload must fit the power actually available.
WAVLINK recommends auxiliary PD power when the host cannot supply all attached functions and suggests using only one external HDD or SSD where laptop output is limited. Follow the storage device’s own supply requirements and finish transfers before changing the power arrangement. A charging headline is not an unlimited peripheral-power budget.
Use this earlier-model reference when identifying or maintaining an actual UMD502 and matching one of its documented display modes. For a new purchase, exact current model identity, a clear USB port map and support for the computer in use are more useful than an old triple-display headline.
Key details at a glance
| USB-C downstream data ports | 0 |
|---|---|
| HDMI outputs | 2 |
| Full-size DisplayPort outputs | 1 |
| Full-size SD slots | 1 |
| microSD slots | 1 |
| Advertised Ethernet link ceiling | 1Gbps |
| Maximum stated power available to host | 60W |
| Power adapter included | No |
| Host requirements | The original guide requires USB-C data, PD and native video. DP version and GPU display-count limits matter. |
| Screen arrangement | Single-screen HDMI1 reaches 4K30. HDMI2 and full-size DP reach 4K60 with DP1.4, or 4K30 with DP1.2. Separate tables govern multiple screens. Mac outputs share one independent external stream. |
| Power and charging | The original UMD502 guide explicitly states maximum 60W delivered to the laptop. Its separate 87W wording is not used as net output. |
| Data and device limits | USB 3.0 and USB 2.0 functions are documented, but per-generation socket counts remain unconfirmed in the accepted edition. |
