UGREEN HD164 15516 Micro HDMI to HDMI 2.1 Cable, 8K 60Hz, 1m
Overview
UGREEN HD164 15516 Micro HDMI to HDMI 2.1 Cable, 8K 60Hz, 1m is documented for a specific connector pair, direction and ceiling. It should be selected by SKU and port geometry rather than by the broad words HDMI, DVI, DisplayPort or VGA.
What it does well.
Key features
02 · At a glance
8K 60Hz / 4K 120Hz. HDMI 2.1 bandwidth up to 48Gbps, with listed ceilings of 8K at 60Hz and 4K at 120Hz.
48Gbps listed. Identify which device is the source/output and which is the display/input. A cable or adapter cannot make two outputs talk to each other, and many display connectors are input-only.
Micro HDMI Type-D. Intended for a Micro HDMI source/output to a full-size HDMI display/input. A reverse physical arrangement works only when endpoint roles and the device makers support it. Direction is a device-role rule, not merely an arrow printed on a cable.
1m braided. No product driver is installed for a passive cable. An active converter can still rely on the host graphics driver and supported output modes even when no separate app is required.
Connectors, direction and interface clarity
03 · Physical fit
Connector / side A. Micro HDMI Type-D male. Use only with the small Micro HDMI port; it is not Mini HDMI Type-C or Micro USB.
Connector / side B. Full-size HDMI Type-A male for a compatible television, monitor, projector, capture device or other HDMI endpoint.
Signal direction. Intended for a Micro HDMI source/output to a full-size HDMI display/input. A reverse physical arrangement works only when endpoint roles and the device makers support it.
Fit before force. Measure and identify Micro HDMI Type-D carefully; forcing the plug into Mini HDMI or Micro USB can damage both connector and device.
Signal, data or power performance
04 · Capability
HDMI 2.1 bandwidth up to 48Gbps, with listed ceilings of 8K at 60Hz and 4K at 120Hz.
Digital video and audio, with Dynamic HDR, 3D and eARC only where the entire connected chain implements the relevant feature. A listed maximum is the ceiling of a correct complete chain, not a promise that every device exposes that mode.
This passive cable does not create an HDMI output, upscale content, add HDR, generate frames or convert USB/DisplayPort.
Use the shortest direct route that reaches without tension, leave a gentle service loop and remove unnecessary converters while testing.
Real digital links can fail as a blank screen, sparkles, dropouts or colour errors; analogue VGA can additionally show softness or ghosting. Start at a conservative known-supported mode before increasing resolution or refresh rate.
What the entire connection must support
05 · Complete path
Identify which device is the source/output and which is the display/input. A cable or adapter cannot make two outputs talk to each other, and many display connectors are input-only.
Match both physical connectors exactly. Measure and identify Micro HDMI Type-D carefully; forcing the plug into Mini HDMI or Micro USB can damage both connector and device.
For protected commercial video, HDCP support must exist at the source, display and every active device. A passive cable or connector adapter cannot add, remove or repair copy protection.
Test one direct path before adding a dock, KVM, wall plate, AV receiver, capture device, coupler or extender. Each added item can change EDID, timing, bandwidth or direction behaviour.
If a separate cable is required at a female socket, that cable becomes part of the signal budget. Its connector type, length and rating matter as much as this product.
Standards, negotiation and operating roles
06 · Behaviour
Intended for a Micro HDMI source/output to a full-size HDMI display/input. A reverse physical arrangement works only when endpoint roles and the device makers support it. Direction is a device-role rule, not merely an arrow printed on a cable.
This passive cable does not create an HDMI output, upscale content, add HDR, generate frames or convert USB/DisplayPort.
Mirror and extended-desktop layouts are created by the source computer and graphics system. One physical connection supplies one display path and does not create additional independent graphics outputs.
Resolution, refresh rate, colour depth, chroma, HDR, audio and protected-content behaviour are negotiated across the chain. A mode name on one device does not override the other endpoint.
The cable or adapter has no user firmware. The graphics driver, display EDID and operating-system settings select the final timing and can require updates even when the accessory itself is plug-and-play.
Ceiling, not a promise
Connector and standard labels describe capability. The complete source, destination, route, settings and negotiated mode determine the result.
Compatible devices and systems
07 · Device fit

Travel presentation. Carry one compact 1m lead for supported Micro HDMI computers or cameras.
Setup and usability guidance
09 · Usability
- Power down the display or stop active output before working around fragile, tightly packed or screw-retained connectors.
- Inspect the source and display ports under good light. Measure and identify Micro HDMI Type-D carefully; forcing the plug into Mini HDMI or Micro USB can damage both connector and device.
- Align each plug with the socket and insert it straight using normal hand pressure. Stop immediately if the connector tilts, binds or requires force.
- Secure DVI or VGA screws finger-tight only, or fully seat the DisplayPort latch where present. Never use retention hardware to pull a plug into alignment.
- Select the correct display input, then begin with 1920×1080 at 60Hz or another documented safe mode before trying the product's maximum listed timing.
- Configure mirror or extended desktop on the source. Route audio separately whenever this product's signal description says video only.
- Support adapters and heavy cables so they do not lever a small HDMI, Micro HDMI or Mini DisplayPort socket; preserve a relaxed bend at every strain relief.
- To disconnect, release latches and screws first, hold the connector shell and pull straight. Do not twist, rock or pull on the cable jacket.
Operating-system, driver and software guidance
10 · Host behaviour
No product driver is installed for a passive cable. An active converter can still rely on the host graphics driver and supported output modes even when no separate app is required.
If the display is detected but blank, choose a lower resolution/refresh rate in the source settings and confirm the destination input. Detection alone does not prove the selected timing is usable.
If mirror works but extended desktop does not, inspect the operating-system display arrangement and GPU limits. The cable carries the configured signal; it does not decide the desktop layout.
If the picture works but there is no sound, compare the signal statement in this guide. DVI and VGA paths here are video-only and need a separate audio output selected in software.
For cameras and capture devices, configure clean output, frame rate, colour mode and HDCP at the source; the cable cannot remove menus, overlays or protected-content restrictions.
Software boundary
The accessory has no user application. Connected hosts and devices can still require model drivers, firmware, permissions or settings.

12 · Clear boundaries
- This passive cable does not create an HDMI output, upscale content, add HDR, generate frames or convert USB/DisplayPort.
- It does not create a graphics output on a port that lacks video capability.
- It does not make an input become an output, join two sources, drive two independent displays from one connection or act as a capture device.
- It does not guarantee the maximum mode, HDR, HDCP, audio or refresh rate when any endpoint or intermediate device lacks support.
- It does not repair a damaged port, marginal cable, incorrect display input, disabled camera output or unsupported operating-system setting.
- It is not interchangeable with lookalike HDMI, Mini HDMI, Micro HDMI, DisplayPort, Mini DisplayPort, USB-C, DVI-I, DVI-D or VGA products.
What to do
13 · Best practice
Recommended. Match SKU 15516, connector gender, direction, length and maximum mode before ordering.
Recommended. Verify a real source/output and display/input, then test the connection directly before permanent routing.
Recommended. Use finger-tight retention, gentle bends, strain relief and enough clearance around adjacent ports.
Recommended. Start at a conservative timing, update the graphics driver or device firmware where appropriate and increase the mode deliberately.
Recommended. Route separate audio when required and label installed cables so future users do not reverse or misidentify them.
What not to do
14 · Common mistakes
Avoid. Do not force a similar-looking connector, trim plastic, bend pins or use screws to draw a crooked plug into place.
Avoid. Do not advertise a one-way converter as bidirectional or a video-only DVI/VGA path as carrying HDMI audio.
Avoid. Do not promise a maximum resolution or refresh rate without checking both endpoints and every intermediate device.
Avoid. Do not suspend a heavy cable or rigid adapter from a small device port or trap the cable under furniture and sharp edges.
Avoid. Do not hot-swap repeatedly during unstable operation; power down, simplify the path and diagnose one variable at a time.
Warnings and limitations
15 · Read before use
Warning / limitation 1. Micro HDMI is mechanically small. Support the cable and avoid side load, especially on cameras mounted to tripods or cages.
Warning / limitation 2. 8K60 and 4K120 are conditional ceilings. Many Micro HDMI devices output only lower modes; select a mode both endpoints accept.
Warning / limitation 3. Keep connectors dry and free of dust. Do not use metal tools or liquid cleaners on an energised port.
Warning / limitation 4. Stop using the product if a shell is loose, pins are bent, the jacket is cut, the strain relief separates, or movement causes intermittent operation.
Warning / limitation 5. Long passive routes, wall plates, KVMs, couplers and adapters reduce signal margin. A setup that works at 1080p may fail at a higher timing.
Warning / limitation 6. Device-specific HDCP, EDID, camera-output, GPU and display limits override broad compatibility examples.
Troubleshooting by symptom
16 · Diagnostics
No display detected. Confirm source/output and display/input roles, select the correct input, reseat both ends, remove intermediate devices and restart the source with the display connected.
Display detected but blank. Select 1080p60 or another known-supported mode, disable unsupported HDR/high-refresh settings and verify that the direction matches this product.
Picture flickers or shows sparkles. Shorten the path, remove couplers, route away from power cables, inspect connector seating and test a lower bandwidth mode.
Image is soft or ghosted. For VGA, shorten and replace the analogue cable; for digital links, verify native resolution, scaling and colour settings at both endpoints.
Video works but sound is absent. Check the signal boundary: Digital video and audio, with Dynamic HDR, 3D and eARC only where the entire connected chain implements the relevant feature. Choose a separate audio route whenever DVI or VGA is in the path.
Only mirror mode appears. Open the operating-system display panel, choose Extend and verify the GPU supports another desktop. The accessory cannot add an independent graphics pipeline.
Works directly but not through a dock or switch. The intermediate device is changing direction, EDID, HDCP or bandwidth. Confirm its specifications or keep the tested direct path.

Questions buyers ask.
Which direction does this model work?
Intended for a Micro HDMI source/output to a full-size HDMI display/input. A reverse physical arrangement works only when endpoint roles and the device makers support it.
What is the highest supported display mode?
HDMI 2.1 bandwidth up to 48Gbps, with listed ceilings of 8K at 60Hz and 4K at 120Hz. Treat it as a conditional complete-chain ceiling rather than a guaranteed result for every device.
Does it carry audio?
Digital video and audio, with Dynamic HDR, 3D and eARC only where the entire connected chain implements the relevant feature. Audio still depends on the source, destination and selected mode.
How do I confirm the ports before buying?
Measure and identify Micro HDMI Type-D carefully; forcing the plug into Mini HDMI or Micro USB can damage both connector and device.
Does it need a driver or app?
The accessory has no user application. Keep the source graphics driver and device firmware current, especially for active conversion, EDID and high-bandwidth modes.
Can I mirror or extend my desktop?
Yes when the source GPU and operating system support that layout. The product supplies one connection; it does not create extra independent graphics outputs.
Why is the screen detected but blank?
The selected timing, direction, HDCP state or intermediate device may be unsupported. Start at a conservative mode and test one direct source-to-display path.
Can I add another adapter or coupler?
Only when its connector, direction and ceiling are explicitly compatible. Every extra item can reduce signal margin or change EDID/HDCP behaviour.
Can this be used as a capture device or splitter?
No. It carries or converts one display path as documented; it neither records video nor produces multiple independent outputs.
How should I disconnect it safely?
Release any latch or screws, grip the connector shell and pull straight. Never twist the plug or pull the cable jacket.
What is included in the package?
One UGREEN HD164 15516 Micro HDMI to HDMI 2.1 Cable, 8K 60Hz, 1m. Check the package section for separately required display, source, audio or extension cables.
