HDMI Male to Female Extension

Unlike a standard HDMI cable with male connectors on both ends, the UGREEN 40447 uses:

• Connector 1: HDMI Male
• Connector 2: HDMI Female
• Configuration: Male → Female
• Purpose: HDMI cable extension

For example:

PS5 → UGREEN 40447 → Existing HDMI Cable → TV

This is useful when an existing HDMI cable is too short or when an HDMI port is difficult to access.

HDMI 2.1 – Up to 48Gbps

The cable is designed for high-bandwidth HDMI transmission.

HDMI Specifications

• HDMI Version: HDMI 2.1
• Maximum Bandwidth: Up to 48Gbps
• Video & Audio: Digital
• Backward Compatibility: Yes

The high bandwidth allows compatible equipment to transmit demanding video formats such as 8K and high-refresh-rate 4K.

8K Ultra HD at 60Hz

The UGREEN 40447 supports resolutions up to 8K at 60Hz with compatible equipment.

Resolution Support

• 8K: Up to 60Hz
• 4K: Up to 120Hz
• 4K @ 60Hz: Yes
• 1440p: Supported
• 1080p: Supported

This makes the extension suitable for modern UHD TVs, gaming monitors, PCs, consoles, and home theater setups.

4K@120Hz Gaming

Support for 4K at 120Hz makes the cable particularly useful for current-generation gaming.

Compatible setups can include:

• PS5 → 4K 120Hz TV
• Xbox Series X → 4K 120Hz Gaming Monitor
• Gaming PC → HDMI 2.1 Monitor

For 4K@120Hz to work, the source, extension cable, main HDMI cable, and display must all support the required HDMI bandwidth.

Ideal for PS5

The UGREEN 40447 can extend an HDMI connection for:

• PlayStation 5
• PS5 Slim
• PS5 Pro

With compatible games and displays, the connection can support features such as 4K@120Hz and HDR.

The extension cable does not increase the PS5's capabilities; it simply extends the HDMI connection.

Xbox Series X|S Compatible

The cable is also suitable for:

• Xbox Series X
• Xbox Series S
• Xbox One

It can be useful when the console is positioned farther away from the TV or gaming monitor than the existing HDMI cable allows.

HDR Support

The HDMI extension supports compatible HDR video signals, allowing supported displays and content to provide enhanced:

• Brightness
• Contrast
• Color
• Highlight detail
• Shadow detail

HDR capabilities ultimately depend on the connected source, main HDMI cable, and display.

Digital Audio & Video

HDMI carries both digital video and audio through a single connection.

The UGREEN 40447 can therefore extend HDMI connections used for:

• Gaming
• Movies
• Streaming
• Home theater
• Presentations
• PC displays

It can also be used with compatible AV receivers, sound systems, and other HDMI equipment.

1-Meter / 3.3FT Extension

The cable provides approximately 1 meter (3.3 feet) of additional HDMI reach.

Length

• Cable Length: 1 Meter
• Equivalent: 3.3ft

This is useful for:

• Wall-mounted TVs
• Gaming consoles
• Desktop PCs
• Projectors

HDMI Extension Cable vs Standard HDMI Cable

The key difference is the female HDMI connector, which allows another HDMI cable or compatible HDMI plug to connect to the extension.

Important Compatibility Note

When using an HDMI extension, the entire HDMI signal chain affects performance.

For example, to achieve 4K@120Hz:

HDMI 2.1 Source + UGREEN 40447 + Compatible HDMI 2.1 Cable + HDMI 2.1 Display

If the additional HDMI cable only supports lower bandwidth, the entire connection may be limited to that cable's capabilities.

Longer total HDMI cable runs can also make maintaining maximum-bandwidth signals more difficult.
