Product Overview

A standard HDMI cable carries digital video and audio between compatible electronic devices. This 20-metre HDMI cable provides extra length for installations where the source device and display cannot be positioned close together.

Whether you need an HDMI cable for a TV, projector, computer monitor, PS4, Xbox or Blu-ray player, this product offers a long wired connection for compatible equipment.

The cable is black and uses HDMI male connectors at both ends. It is listed for High-Speed HDMI transmission, video resolutions up to 4K Ultra HD, digital audio and compatible 3D content.

 

Who Is This HDMI Cable For?

This 20m HDMI cable is suitable for:

• Home users connecting televisions, media players and gaming consoles over longer distances.
• Gamers connecting compatible PS4 or Xbox consoles to televisions and monitors.
• Offices connecting laptops and computers to projectors or large displays.
• Schools and training centers displaying lessons and presentations.
• Churches and event venues connecting compatible audiovisual equipment.
• Hotels and conference facilities setting up display and presentation systems.
• Businesses and institutions requiring extended HDMI connections.
• Technicians and audiovisual installers working with compatible display equipment.

 

Key Features and Benefits

1. Extended 20-Metre Cable Length

The 20-metre length allows compatible devices to be connected across a larger room or installation area.

It is useful when a television, projector or monitor is positioned far from the computer, gaming console or media player supplying the signal. Measure the complete cable route before purchasing to ensure that the length accommodates the installation.

 

2. Up to 4K Ultra HD Video Support

The cable is specified to support up to 4K Ultra HD video, as well as Full HD and HD video.

This makes it suitable for compatible displays that accept the required signal. Actual resolution and performance depend on the source device, display, cable characteristics and signal requirements of the setup.

For installations requiring a specific refresh rate or advanced video feature, confirm compatibility before purchasing.

 

3. High-Speed HDMI Transmission

The product is categorized as a High-Speed HDMI cable for digital audio and video connections.

It can be used for compatible home entertainment equipment, gaming systems, computers and presentation displays. The supplied specifications do not provide a numerical bandwidth rating or a precise HDMI version, so these should be confirmed if they are essential to your application.

 

4. 19+1 Copper Wire Core

The cable uses a stated 19+1 copper wire core, including an additional ground wire.

This is part of the product’s specified construction. Buyers with specialized installation requirements should confirm any additional conductor or shielding details needed for their project.

 

5. Digital Audio Support

The cable supports digital audio transmission and lists Dolby True-HD, DTS-HD and Master Audio support, with up to 32 sound channels simultaneously.

Compatible source devices and receiving equipment are required to use the relevant audio formats and channel configurations. The available audio features depend on the entire connected system.

 

6. 24K Gold-Plated Connectors

The cable features 24K gold-plated connectors with aluminum alloy housing.

These are stated product construction features. To maintain reliable connections, handle the connectors carefully and avoid pulling the cable by its ends.

 

7. Ethernet Support

The product information specifies 10/100 Mbps network transmission, with speeds of up to 100 Mbps when used with compatible devices.

Actual Ethernet functionality depends on support for the relevant HDMI Ethernet feature by the connected equipment. The cable does not independently provide internet access to devices that do not support this functionality.

 

8. Dual-Screen Display Support

The supplied specifications list dual-screen display support and up to four voice signal streams for compatible devices.

The actual display and audio configuration depends on the source device and the connected equipment. Check the manufacturer’s specifications if you need this feature for a particular installation.

 

9. Compatible 3D Content Support

The cable is specified to support compatible 3D content.

The source device, display and content must support the relevant 3D format. Connecting the cable does not add 3D functionality to equipment that lacks it.

 

10. Broad Device Compatibility

The cable is listed for use with a range of HDMI-enabled devices, including:

• HDTVs and compatible televisions
• PS4 and Xbox gaming consoles
• Blu-ray players
• Projectors
• Set-top boxes
• Laptops and desktop computers
• Compatible monitors
• Other HDMI-enabled equipment

Check the available ports and supported signal formats on both devices before making a connection.

Applications of the 20m HDMI Cable in Ghana

Home Entertainment

Use the cable to connect compatible media players, computers or gaming consoles to a television positioned farther away.

Its extended length can provide flexibility for larger living rooms and entertainment spaces where the devices cannot sit beside each other.

 

Gaming Setups

The cable is listed as suitable for compatible PS4 and Xbox consoles. It can connect a console to a compatible television or monitor when a longer cable route is required.

For gaming, confirm the resolution and refresh rate supported by the console, display and cable configuration.

 

Offices and Conference Rooms

Businesses can use the cable to connect a laptop or desktop computer to a projector or large screen during meetings, presentations and training sessions.

The 20-metre length can help accommodate rooms where the presenter and display are positioned far apart.

 

Schools and Universities

Educational institutions can use HDMI connections to display slides, videos and learning materials through compatible projectors or monitors.

The cable may be useful in larger classrooms, lecture halls and training rooms where a longer connection is necessary.

 

Churches and Event Venues

Churches and event organisers may need to connect compatible video sources to projectors or displays across a hall.

The cable can support these setups when its length and signal capabilities meet the installation requirements. Route it safely to reduce the risk of tripping or accidental damage.

 

Hotels and Commercial Businesses

Hotels, conference facilities and other businesses may use the cable for compatible presentation and entertainment equipment.

For permanent installations, plan the cable route carefully and ensure that the connectors remain accessible for maintenance.

 

How to Choose and Install the Right HDMI Cable

Check the Cable Length

Measure the full distance the cable must travel, including corners, wall routing and the positions of the connected devices.

A 20m HDMI cable is intended for extended connections. If the equipment is close together, a shorter cable may be easier to manage.

 

Confirm Connector Compatibility

This product has standard HDMI male connectors at both ends. It does not directly replace VGA, DisplayPort, mini HDMI or USB-C connections.

If your computer uses USB-C or DisplayPort for video output, you may need a compatible adapter. Confirm the device’s video output capabilities and the adapter’s supported direction before purchasing.

 

Check the Required Video and Audio Features

Confirm the resolution and other signal features required by your source device and display.

For a 4K installation over a long distance, verify that the specific cable and equipment can support the required signal reliably.

 

Follow These Installation Steps

1. Check that both devices have compatible HDMI ports.
2. Measure the complete cable route.
3. Connect the HDMI male ends to the source device and display.
4. Select the correct HDMI input on the display.
5. Test the video and audio before securing the cable permanently.
6. Route the cable away from walkways and areas where it may be crushed or pulled.

 

Avoid Common Buying Mistakes

• Choosing a cable that is too short for the complete route.
• Assuming that 4K support guarantees every refresh rate or advanced video feature.
• Confusing a standard HDMI cable with a VGA-to-HDMI converter or USB-C adapter.
• Assuming Ethernet functionality works with every HDMI device.
• Installing the cable permanently before testing the required signal.
• Leaving the cable across a busy walkway where it could cause a trip hazard.

 

Care and Maintenance

To help protect the cable and its connectors:

• Avoid sharp bends and crushing pressure.
• Do not pull the cable by its connectors.
• Keep the connectors free from unnecessary strain.
• Secure the cable without overtightening cable ties or clamps.
• Keep the cable away from walkways where people may trip over it.
• Check the connections if the picture or audio becomes intermittent.
• Test the complete setup before finalising a permanent installation.
