UGREEN 40216 is a powered 4-input, 2-output HDMI matrix that can select which source feeds each HDMI display and can also send the same selected source to both displays. This buying guide makes the port direction, display behavior, power, cable requirements and limitations clear before installation.
SKU 40216Up to 4K at 30Hz; up to 1080p at 60HzMATRIX
SKU 40216: model overview: the powered matrix accepts four HDMI sources, drives two HDMI outputs and includes local plus IR selection.
1
Overview
Four HDMI source inputs → independent A/B matrix selection → two HDMI display outputs. Optical S/PDIF and 3.5mm analogue audio outputs provide separate audio connection options from the matrix path.
Correct direction is the first troubleshooting check. Similar-looking HDMI, DisplayPort and USB-C products can require completely different source and display sides.
SKU 40216: The source side shows the 5V power inlet and numbered HDMI inputs; label each source before assigning it to Output A or B.
SKU 40216: Output A sits beside optical S/PDIF and 3.5mm audio connections, allowing compatible audio to leave the selected HDMI path separately.

How switching and multi-display behavior works
Matrix mode can route different selected inputs to Output A and Output B; splitter-style use can place the same selected source on both outputs. It does not create two independent desktops from one source.
Control: Front-panel controls and included IR remote.
Never assume: a product advertised as “bidirectional,” “splitter” or “matrix” behaves like another topology. Follow the source/output map above.
SKU 40216: The diagram illustrates source selection for a two-display installation; matrix routing can differ by output, while splitter-style use can duplicate one source.

Resolution, refresh and feature boundary
Maximum listed mode
Up to 4K at 30Hz; up to 1080p at 60Hz
Interface boundary
HDMI 1.4 as listed
Audio path
Compatible HDMI audio, plus optical S/PDIF and 3.5mm extraction. ARC is listed for this model, but eARC is not established and no eARC claim is made.
Complete-path rule
Source, every cable, selector/distributor, display input, EDID and protected-content requirements must all agree. One weaker component can lower or blank the link.

Use scenarios
Scenario 1
Route a PC to one monitor and a media player to a projector
Scenario 2
Send the same presentation to two HDMI displays
Scenario 3
Share four HDMI sources between a meeting-room display pair
Scenario 4
Extract audio to an optical receiver or 3.5mm speaker path
SKU 40216: A matrix is useful when several HDMI sources must remain connected to a television, monitor or projector pair without repeated cable swapping.
6
Setup and usability guidance
Step 1: Connect the supplied 5V/1A adapter before source selection.
Step 2: Connect each source to a numbered HDMI input and label the cable.
Step 3: Connect Output A and Output B to the intended displays.
Step 4: Add optical or 3.5mm audio only if required and supported by the chosen source format.
Step 5: Power displays first, then the matrix, then sources; select a conservative 1080p mode for first test.
Step 6: Use the panel or remote to assign inputs, then raise resolution only after both paths are stable.
Best first test: one source, one short cable path, one display and 1080p60. Expand only after this baseline works.
SKU 40216: Place the matrix where its IR receiver remains visible and keep the included remote pointed toward the unit when changing either output assignment.

What this product does not do
Not an 18Gbps 4K60 matrix
Not a two-computer KVM; it does not switch USB keyboard or mouse
Not an HDMI capture or recording device
Not an eARC processor
Protected content still requires source, matrix and both displays to agree on the relevant HDCP path
10
What to do
Label
Label every source, output and power cable before installation.
Build gradually
Start at 1080p60 with one display, then add outputs or increase resolution in stages.
Verify cables
Use short, cables for 4K/high-refresh operation and replace suspect cables before changing advanced settings.
Power safely
Keep ventilation openings clear and use only the specified power arrangement.
Record settings
Save working resolution, HDR, HDCP and audio settings for future troubleshooting.
11
What not to do
Do not reverse
Do not infer reverse direction or simultaneous outputs beyond the topology.
Do not confuse
Do not treat a switch as a splitter, a splitter as a switch, or either as a capture device.
Do not assume scaling
Do not assume every display can use its own independent resolution or refresh rate.
Do not force
Do not force connectors, hot-plug damaged cables or use an unverified power supply.
Do not overclaim
Do not promise DSC, MST, eARC, VRR or gaming modes unless this SKU explicitly lists them.

Product-specific FAQ
What does UGREEN 40216 do?
It is a powered 4-input, 2-output HDMI matrix that can select which source feeds each HDMI display and can also send the same selected source to both displays.
What is the signal direction?
Four HDMI source inputs → independent A/B matrix selection → two HDMI display outputs. Optical S/PDIF and 3.5mm analogue audio outputs provide separate audio connection options from the matrix path.
What is the maximum display mode?
Up to 4K at 30Hz; up to 1080p at 60Hz. The final mode is limited by the source, every cable, the switch/splitter and the display or displays.
Can it create an extended desktop?
The matrix can route selected sources independently to its two outputs, but it cannot create two independent desktops from one source. Matrix mode can route different selected inputs to Output A and Output B; splitter-style use can place the same selected source on both outputs. It does not create two independent desktops from one source.
Does it need external power?
DC 5V/1A adapter required and listed in the kit.
Does it carry audio?
Compatible HDMI audio, plus optical S/PDIF and 3.5mm extraction. ARC is listed for this model, but eARC is not established and no eARC claim is made.
Which cables are required?
The listing gives up to 12m input + 12m output for 4K30 and up to 20m + 20m for 1080p60. These are best-case listed limits, not guarantees for every cable or environment. Cables not named in the package contents must be supplied separately.
What should I try if there is no picture?
Confirm the signal direction and active source, attach required power, select the correct display input, reseat cables and begin at 1080p60 with one display. Add other outputs or higher modes only after a stable base link.
Can it improve resolution, refresh rate or HDCP?
No. It can only pass or route modes already supported throughout the complete connection. It cannot upgrade a source, cable or display.
What is included?
1 × UGREEN 40216 HDMI matrix, 1 × IR remote, 1 × 5V/1A power adapter and product documentation as pictured/listed. HDMI, optical and 3.5mm cables are not identified as included.
What model conflicts were removed?
The record establishes four inputs, two HDMI outputs, audio extraction, 5V/1A power and 4K30. The old title leads with 1080p and calls the matrix a splitter; the corrected copy distinguishes independent matrix routing from duplicate-output use. Text conflicts between “metal” and “ABS” housing were excluded.
Before ordering UGREEN 40216
Match the source connector, display connector, topology, power method and highest mode you really need. Count separately purchased HDMI, DisplayPort and USB-C cables before installation day.
