Fiber Optic Technology

One of the main advantages of the ProLink4K60-20M is its fiber optic construction. Promate specifically designed this cable for reliable HDMI signal transmission across its long 20-meter distance.

This makes it especially suitable for:

• Large rooms
• Home theaters
• Conference rooms
• Ceiling-mounted projectors
• Commercial displays
• Gaming rooms
• Long-distance PC-to-monitor/TV connections
• Professional AV installations

Unidirectional HDMI Cable

The ProLink4K60-20M is unidirectional, meaning the connectors must be installed in the correct direction. Promate specifies that the signal travels from the source device to the display.

SOURCE → ProLink4K60-20M → DISPLAY

For example:

Gaming PC → HDMI Cable → 4K TV

or

Laptop → HDMI Cable → Projector

Because it is directional, reversing the cable may result in no picture or audio.

Ethernet Support

The cable supports HDMI Ethernet functionality, allowing compatible HDMI Ethernet Channel devices to share network functionality through the HDMI connection.

This does not mean the cable has an RJ45 Ethernet connector; both ends are standard HDMI connectors.

3D Video Support

The ProLink4K60-20M supports 3D video, making it suitable for compatible 3D source devices and displays. Promate includes 3D support among the core features of this model.

Gold-Plated Connectors

The HDMI connectors feature a gold-plated design intended to provide reliable contact and resistance against corrosion.

Extra-Long 20-Meter Cable

• Cable Length: 20 meters
• Approximately 65.6 feet

The 20M length makes the cable particularly useful for installations where the HDMI source and display are located far apart.

Specifications

Promate's official specifications confirm the 4K@60Hz resolution, 18Gbps transfer rate, 20-meter length, fiber-optic construction, Ethernet support, and unidirectional design.

Wide Compatibility

Suitable for HDMI-equipped:

• Gaming PCs
• Desktop PCs
• Laptops
• 4K UHD TVs
• HDTVs
• Gaming monitors
• Professional monitors
• Projectors
• Gaming consoles
• Blu-ray players
• Streaming devices
• AV equipment
• Conference room displays

Important Direction Note

Because the ProLink4K60-20M is an active fiber-optic HDMI cable, it is directional. Make sure the Source end is connected to the transmitting device and the Display end to the TV, monitor, or projector.

This is especially important when installing the cable inside walls, ceilings, or cable conduits.

Important Note

To achieve 4K@60Hz, both the source and display must support 4K@60Hz over HDMI.

This model is designed around HDMI 2.0-class 18Gbps performance. It should therefore not be listed as an HDMI 2.1 48Gbps cable, and it is not intended for demanding HDMI 2.1 modes such as 4K@120Hz or 8K@60Hz.

Best For

• Long-Distance HDMI Connections
• 4K@60Hz TVs & Monitors
• Projectors
• Home Theater Systems
• Gaming PCs
• Gaming Consoles
• Conference Rooms
• Offices
• Commercial Displays
• Professional AV Installations
• Ceiling-Mounted Projectors
