Custom DVI Adapter for Legacy and Multi-Interface Display Connections

Len-Link provides custom DVI adapter solutions for computers, monitors, projectors, graphics systems, industrial displays, KVM equipment and established AV installations where different DVI connector formats or display interfaces must remain compatible.

Instead of selecting a DVI adapter only by appearance, you should confirm the connector type, pin configuration, signal requirement, connector gender and destination interface before ordering.

DVI Adapter Types Available from Len-Link

Different DVI connectors can look very similar while supporting different signal configurations. The existing Len-Link range allows you to select an adapter around both the DVI interface and the device it needs to connect.

18+1 DVI Adapter

18+1 is commonly associated with single-link DVI-D configurations used for digital video connections.

Len-Link currently offers an 18+1 DVI Male to HDMI Female adapter, providing an option for suitable digital DVI equipment that needs to connect with HDMI infrastructure.

This type of configuration is relevant for:

• Desktop computers

• Graphics cards

• Monitors

• Projectors

• Existing digital display systems

• AV replacement projects

24+1 DVI Adapter

24+1 is used in DVI-D configurations where digital video is required.

The current Len-Link range includes 24+1 DVI Male to HDMI Female adapters as well as a 360-degree rotatable 24+1 DVI-to-HDMI design.

The rotatable structure can be particularly useful where the equipment is:

• Installed close to a wall

• Mounted inside a cabinet

• Positioned behind a display

• Installed in a restricted enclosure

• Subject to difficult cable-routing angles

24+5 DVI Configurations

18+5 and 24+5 connector layouts are associated with DVI-I configurations that can accommodate digital and analog signal arrangements depending on the complete system.

Len-Link currently offers products including:

• 24+5 DVI Female to Female

• 24+5 DVI Male to VGA Female

• 24+5 DVI Female to VGA Male

• 24+5 DVI Female to HDMI Female

• 24+5 DVI Female to HDMI Male

These configurations make the DVI Adapter category particularly relevant for projects maintaining compatibility between newer and older display equipment.

How to Identify the DVI Adapter You Need

When sourcing a custom DVI adapter, start with the actual ports on both devices rather than the product name alone.

Providing connector photos is especially useful for older equipment where the exact DVI type is not clearly documented.

DVI-D vs DVI-I: Why the Difference Matters

The connector configuration is one of the most important factors when specifying a DVI adapter.

DVI-D

DVI-D is intended for digital video.

Common pin arrangements include:

• 18+1

• 24+1

For a digital DVI-to-HDMI application, the project should normally be defined around the actual DVI-D configuration, connector gender and target equipment.

DVI-I

DVI-I connector configurations can accommodate both digital and analog signal arrangements, depending on the connected equipment and actual wiring.

Common configurations include:

• 24+5

This is especially relevant to DVI-to-VGA projects because VGA is an analog interface.

DVI to HDMI Adapter

DVI-to-HDMI is one of the main product groups within the current Len-Link DVI Adapter range.

These adapters can be used where compatible digital DVI equipment needs to connect with HDMI displays or existing HDMI cables.

Possible configurations include:

• 18+1 DVI Male to HDMI Female

• 24+1 DVI Male to HDMI Female

• 24+5 DVI Female to HDMI Female

• 24+5 DVI Female to HDMI Male

When specifying this type of product, confirm the DVI interface first.

You should also note that DVI is primarily a video interface, so the use of an HDMI connector does not by itself guarantee that audio will be available through the DVI side.

DVI to VGA Adapter for Analog Display Equipment

Len-Link currently provides several 24+5 DVI and VGA combinations.

These adapters are relevant where equipment with a compatible DVI-I interface needs to remain connected with VGA monitors, projectors or other analog display systems.

Common applications include:

• Older office monitors

• Projectors

• Industrial computers

• Control-room displays

• Test equipment

• Maintenance systems

• Existing KVM installations

DVI Female-to-Female Adapters

Female-to-female DVI adapters can be used as couplers where two compatible DVI connections need to be joined.

This type of product may be suitable for:

• Existing cable extension

• Rack installations

• Equipment relocation

• Temporary test systems

• Maintenance replacement

• Panel-based connections

A coupler does not change the underlying signal capability. Both sides of the connection still need to be electrically and mechanically compatible.

DVI Adapter Compatibility Matrix

A simple interface matrix can help determine which Len-Link product group is most relevant.

Custom DVI Adapter Manufacturing

Many DVI projects today are not new consumer-device designs. They are replacement, maintenance, industrial or system-integration requirements where the interface is already fixed.

This makes customization particularly important.

Len-Link supports OEM/ODM projects and can evaluate a custom DVI adapter according to the required connector configuration and installation.

Connector Configuration

Project requirements can be defined around:

• DVI-D

• DVI-I

• 18+1

• 24+1

• 18+5

• 24+5

• Male-to-female

• Female-to-female

• DVI-to-HDMI

• DVI-to-VGA

Mechanical Structure

Depending on the equipment, customization can include:

• Straight structure

• Connector orientation

• Housing dimensions

• Compact housing

• Equipment-specific mechanical requirements

Housing and Appearance

OEM requirements can also cover:

• Housing material

• Housing color

• Surface appearance

• Connector finish

• Logo

• Product identification

• Model marking
