DisplayPort cable Lenovo 4X91U92142 — DisplayPort to DisplayPort, 1.8 m, black

Lenovo 4X91U92142 is a DisplayPort to DisplayPort cable, 1.8 m long, designed for connecting monitors, graphics cards and other DisplayPort-enabled devices. The cable conforms to DisplayPort 1.4 specification and provides a full digital transmission of audio and video over a single lead. With a maximum bandwidth of 32.4 Gbps and support for Display Stream Compression (DSC) where supported by connected devices, it can carry high-resolution signals including up to 8K at 60 Hz, making it suitable for high-fidelity desktop and workstation video connections that require a 1.8 m lead.

Advantages

This Lenovo DisplayPort cable offers a compact, single-cable solution for high-bandwidth digital video and audio transmission. The 1.8 m length balances reach and signal integrity for typical desk or workstation setups. Conformance to DisplayPort 1.4 ensures support for advanced features such as DSC-enabled higher resolutions and 3D content when both source and display support those capabilities. The cable’s construction yields a lightweight assembly (approximately 80 g) with a 6.1 mm diameter suitable for standard routing and installation.

Suitable for

• Connecting desktop PCs or workstations to external monitors
• High-resolution displays up to 8K 60 Hz when DSC is supported by devices
• Graphics cards with DisplayPort outputs to DP-enabled displays
• Multi-monitor workstation setups requiring a 1.8 m cable length

Key specifications

• Connector type: DisplayPort to DisplayPort (male to male)
• DisplayPort version: 1.4
• Maximum bandwidth: 32.4 Gbps
• Maximum supported resolution: up to 7680 x 4320 (8K) at 60 Hz with DSC support
• Cable length: 1.8 m
• Cable diameter: 6.1 mm
• Color: black
• Weight: approximately 80 g
• RoHS compliance

How to use

Connect one DisplayPort connector to the DisplayPort output on your PC or graphics card and the other end to the DisplayPort input on your monitor or display. Ensure both devices are powered off or set to safe input mode when connecting if recommended by the device manufacturers. After connection, power on the devices and select the appropriate DisplayPort input on the monitor. Configure resolution and refresh rate in the operating system or GPU control panel to match the capabilities of the display and the cable (for example, enabling DSC on compatible devices to reach 8K at 60 Hz).

Recommendations

Use the Lenovo 1.8 m DisplayPort 1.4 cable for typical desk and workstation distances to maintain signal integrity. For very long runs beyond 1.8 m, consider active or certified long-reach cables or signal extenders. When targeting maximum resolutions (such as 8K at 60 Hz), verify that both the source and display support DisplayPort 1.4 features and DSC, and confirm GPU driver settings and monitor firmware are up to date.
