UGREEN HDMI Female-to-Female Coupler 1-Pack, 4K60 (20107)
Overview
UGREEN 20107 is a one-pack of passive HDMI Type-A female-to-female couplers. Each unit joins two standard HDMI male cable plugs or changes a male cable end into a female connection point. The record lists up to 4K60, HDR and compatible audio/optional HDMI pass-through, but every added cable segment and junction reduces signal margin.
What it does well.
Key features
Product highlights
HDMI female ↔ female. Product capability, subject to the complete end-to-end connection.
Up to 4K60. The defining connector, protocol or construction detail for this SKU.
One clear job. Joins two HDMI Type-A male plugs through one passive female-to-female unit.
No hidden upgrade. It does not amplify, repeat, clean or regenerate HDMI.
Maximum versus actual: Up to 3840 × 2160 at 60Hz, plus listed lower modes including 2560 × 1600, 2560 × 1440, 1920 × 1200 and 1080p. Compatible ARC, HDMI Ethernet Channel, 3D and listed 5.1/7.1 digital audio pass-through when the entire HDMI chain supports them. The coupler does not regenerate the signal; total length, both cable ratings, connector quality and endpoints determine stability.
Choose the right connection
Port and direction check
1 × HDMI Type-A female sockets per coupler; one separate HDMI Type-A male-to-male cables are required for an extension
The passive female-to-female coupler is physically reversible. Device roles still remain source output to display input, and the complete joined path must support the requested signal.
Inspect labels and connector shapes under good light. Mini HDMI, Micro HDMI, DisplayPort, HDMI, USB-C, USB-A, USB-B and RJ45 are distinct; even matching USB-C sockets may support different data, power or video functions.
Connection rule: never force a plug and never assume an adapter, hub or switch works in reverse or adds a mode, power profile, audio format or protocol the endpoints lack.
Performance and signal path
Video, data, power and audio
Up to 3840 × 2160 at 60Hz, plus listed lower modes including 2560 × 1600, 2560 × 1440, 1920 × 1200 and 1080p. Compatible ARC, HDMI Ethernet Channel, 3D and listed 5.1/7.1 digital audio pass-through when the entire HDMI chain supports them. The coupler does not regenerate the signal; total length, both cable ratings, connector quality and endpoints determine stability.
A maximum resolution, refresh rate, data rate, link speed, pickup distance or wattage is a ceiling rather than a guaranteed result. The complete host, cable, power, peripheral and receiving-device path controls the working outcome.
When a high mode or combined setup fails, establish one conservative direct function first, then add load or raise one setting at a time while checking picture, data, power, network and audio behaviour.
Use scenarios
Where it fits
Join two HDMI cables. Extend a tested source-to-display route by coupling two male-ended HDMI cables.
Reposition a display cable. Move the connection point while keeping the coupler supported and accessible.
Temporary presentation route. Join two suitable HDMI cables for a tested indoor projector connection.
Home-theatre cable management. Connect two known-good segments without claiming a fixed total distance.
Bench testing. Use one coupler while diagnosing cable reach, then test each segment directly.
Two-location spare set. Keep the second coupler as a spare rather than daisy-chaining both units.
Scenario boundary: every example assumes the actual source output, signal direction, receiving input, graphics hardware and operating system support the requested use.
Setup and usability guidance
A reliable first connection
Follow a controlled sequence so connector, direction, display, data, power, network and audio faults remain easy to isolate.
After setup: record the working ports, mode, power source, selected device and cable path before adding more peripherals, joins or switching equipment.
- Test each HDMI cable directly at the intended mode.
- Power down or place source and display in standby.
- Insert one HDMI Type-A male plug into each side of one coupler.
- Support the joined cables so their weight does not pull on the coupler or endpoint ports.
- Select the display input and begin at a conservative mode.
- Raise the mode within the 4K60 ceiling only after the path is stable.
- If dropouts appear, remove the coupler and test each segment separately.

What this product does not do
Important exclusions
These exclusions prevent the most common wrong-product purchases and unsafe installations.
Choose another product when needed: use the correct directional converter, splitter, switch, capture device, audio route or installation-rated cable for functions outside this model’s role.
- It does not amplify, repeat, clean or regenerate HDMI.
- It does not guarantee a fixed extension distance.
- It does not improve a cable, source or display that lacks the requested mode.
- It does not split one source to two displays or switch between sources.
- It does not include either required HDMI cable.
- It does not state an HDCP version or guarantee protected-content playback.
What to do
Best-practice checklist
Protect the connection and make later diagnosis straightforward.
A labelled, supported and tested connection is easier to maintain than one hidden immediately after purchase.
- Confirm every physical port and its input/output role before making the connection.
- Begin with a direct, conservative setup and add higher modes or extra devices only after it is stable.
- Hold connector housings rather than cables and leave every small device port free of tension.
- Use correctly rated, undamaged external cables and power accessories where the product requires them.
- Change one variable at a time when troubleshooting so the limiting component remains identifiable.
- Keep the product dry, supported, ventilated and accessible for inspection.
What not to do
Avoid these mistakes
Most failures come from wrong interfaces, unsupported claims, strain or uncontrolled channel changes.
Stop using the product if a connector, housing, jacket or lead is cracked, loose, contaminated, unusually hot or exposes conductive parts.
- Do not force a plug into a similar-looking connector or assume all USB-C and HDMI-shaped ports have the same functions.
- Do not pull, crush, sharply bend, staple or let accessory weight hang from a host port.
- Do not treat a printed maximum as guaranteed performance from every source, cable, display or peripheral.
- Do not disconnect storage, video or power paths during an active transfer, firmware operation or write process.
- Do not use the product outdoors or permanently inside a wall without the required published rating.
- Do not continue using cracked, loose, contaminated or abnormally hot connectors or housings.
Warnings and limitations
Read before installation
The following limits remain important even when the connector appears to fit.
Permanent routes: test the complete real setup first and follow local electrical, building and workplace requirements.
- Every added connector reduces signal margin, especially at 4K60.
- Both cable segments and both endpoints must support the selected mode and features.
- Use one correct-length cable instead of daisy-chaining couplers where practical.
- Support the joined cables so the coupler does not hang by the device ports.
- No fixed distance or HDCP-version guarantee is made.
- No outdoor, in-wall, plenum, direct-burial, LSZH or fire-resistance rating is stated for this product.

What does each coupler connect?
Two HDMI Type-A male plugs through two female sockets.
How many couplers are included?
Two, according to the current package description and gallery image.
Is it directional?
The passive coupler is physically reversible, but source-output and display-input roles still apply.
Can it support 4K60?
Yes on a complete path where both cables and endpoints support 4K60 with adequate margin.
Does it boost the signal?
No. It is passive and performs no amplification or regeneration.
How far can it extend HDMI?
No fixed distance is guaranteed; mode, cable quality, total length and endpoints control stability.
Does it support HDR?
HDR can pass only when every component in the joined path supports it.
Does it carry audio?
It can pass compatible HDMI audio; optional ARC and specific formats remain full-path dependent.
Can it split one source to two displays?
No. Use an HDMI splitter designed for that job.
Is an HDCP version guaranteed?
No HDCP version is safely stated.
Are HDMI cables included?
No. Two male-to-male HDMI cable segments are required for an extension.
