DVI Cable Manufacturer for Display and Legacy Equipment

Len-Link manufactures DVI cable assemblies for monitors, projectors, graphics systems, industrial displays, medical equipment, control terminals and legacy AV installations.

As a DVI cable manufacturer, we support standard and project-based orders covering DVI connector type, pin configuration, link type, cable length, shielding, connector shell, screw-locking, labeling and packaging.

The current product range includes a DVI-D 24+1 male-to-male cable for digital display connections. Additional cable configurations can be evaluated according to the equipment interface and required signal.

Select the Correct DVI Configuration

DVI connectors can look similar while supporting different signals. Before requesting a quotation, buyers should identify the exact connector and signal required by both devices.

A DVI-D plug cannot transmit an analog signal. A DVI-I connector may carry both signal types, but actual compatibility still depends on the source equipment, display and adapter configuration.

Single-Link or Dual-Link?

A DVI cable manufacturer should confirm the internal wiring rather than relying only on the visible connector pins.

Single-Link DVI

Single-link DVI is suitable for many established monitor, projector and industrial display systems requiring resolutions up to approximately 1920 × 1200 at 60Hz.

It is commonly used for:

• Standard office monitors

• 1080p displays

• Projectors

• Industrial control terminals

• Replacement cables for existing equipment

Dual-Link DVI

Dual-link DVI uses additional digital channels and should be selected when the connected equipment requires greater bandwidth or resolutions such as 2560 × 1600 at 60Hz.

A 24+1 connector should not automatically be described as dual-link unless all required signal pins are connected and the finished cable has been validated for the intended resolution.

Cable Length and Signal Stability

The required resolution and cable length should be evaluated together.

A longer cable creates greater signal loss than a short assembly. Cable gauge, conductor material, pair construction, shielding and connector termination can all affect display stability.

For longer runs or high-resolution applications, buyers should confirm:

• Final production length

• Required resolution

• Conductor gauge

• Shielding structure

• Ferrite-core requirement

• Equipment compatibility

• Whether an active signal solution is necessary

• Sample-testing conditions

The current Len-Link 24+1 cable lists lengths up to 3 metres and support for resolutions up to 1920 × 1200 and 1080p@60Hz.

Shielding and Connector Construction

A shielded DVI cable is commonly selected for office equipment, industrial systems, control rooms and installations where other power or signal cables may create electromagnetic interference.

Depending on the project, the cable structure can be evaluated for:

• Individual signal-pair shielding

• Aluminum-foil shielding

• Braided overall shielding

• Drain wire

• Ferrite cores near one or both connectors

• Molded connector strain relief

• Metal internal connector protection

• Gold- or nickel-plated contacts

• Screw-locking connector retention

The shielding method should be defined in the approved specification. Terms such as “double shielded” are not sufficient unless the actual foil, braid and coverage requirements are recorded.

Replacement Cables for Existing Equipment

Many DVI projects involve equipment that remains in service even though newer display interfaces are available. Examples include industrial computers, medical imaging systems, test equipment, CNC controls, security monitors and commercial display installations.

For these projects, the priority is not adding the latest video standard. The priority is reproducing a cable that fits the existing equipment and maintains stable operation.

As a DVI cable manufacturer, Len-Link can evaluate:

• An existing cable sample

• A connector pinout

• Equipment interface photos

• Cable labels or part numbers

• Required cable length

• Screw and shell dimensions

• Existing installation constraints

• Expected annual replacement quantity

The sample evaluation should confirm pin continuity, signal type, connector fit and display operation before bulk production.

Converting DVI to Other Display Interfaces

DVI may be connected to HDMI, DisplayPort or VGA equipment, but the conversion method depends on the source signal and target interface.

DVI to HDMI

DVI-D and HDMI both carry digital video, so compatible equipment may use a passive cable or adapter. DVI does not normally carry HDMI audio, so buyers should confirm whether separate audio is required.

DisplayPort to DVI

DisplayPort-to-DVI projects may require a passive or active conversion solution depending on the source output and target display.

DVI to VGA

DVI-I may provide analog compatibility when the source supports analog output. DVI-D is digital-only and cannot be converted to VGA with a simple passive adapter.

The source and display direction should always be stated because active conversion cables may not operate in reverse.

Manufacturing Support for Bulk Orders

Len-Link operates a 5,000 m² facility with more than 150 employees and annual cable output exceeding one million units. The company supports OEM/ODM orders, sample evaluation, production-process videos and customized packaging.

Selected standard products may support quantities starting from 100 pieces. MOQ for modified or newly developed DVI assemblies depends on connector availability, cable structure, tooling, testing and packaging.

When evaluating a DVI cable manufacturer, buyers should confirm that future orders will follow the same approved pinout, shielding, connector and cable construction. This is particularly important for replacement parts used across a long equipment service life.

Frequently Asked Questions

How do I identify whether I need DVI-D or DVI-I?

Check the source and display ports, equipment manuals or connector pin layout. DVI-D supports digital signals only, while DVI-I can support digital and analog signals when the connected equipment provides both.

Does a 24+1 connector always mean dual-link?

No. The connector may have 24 digital pin positions, but the internal cable must include the required dual-link conductors. Ask for the wiring specification and resolution test results.

Can you manufacture a cable from an existing sample?

Yes. A reference sample can be evaluated for connector type, pinout, length, shielding and mechanical construction. Equipment-level testing is recommended before bulk production.

Can DVI carry audio?

Standard DVI is primarily a video interface. Some equipment configurations may pass audio through digital conversion, but this should not be assumed. Confirm the complete source and display requirements.

Can the cable length be customized?

Yes. The supported resolution and signal stability should be validated at the requested production length.

Can DVI-D connect directly to VGA?

No. DVI-D carries digital signals only. A suitable active converter is required to connect a DVI-D source to an analog VGA display.
