Questions & Answers

How can I identify which DVI connector type I have or need?
You can identify the DVI connector type by the pin configuration and determine compatibility based on whether the connection supports analog, digital, or both signal types. Explanation: DVI (Digital Visual Interface) connectors are defined by their pin layout and supported signal type. The main DVI connector types are: DVI-A (17 pin) . Analog signal only DVI-D Single Link (19 pin) . Digital signal only DVI-D Dual Link (25 pin) . Digital signal only, higher bandwidth DVI-I Single Link (23 pin) . Supports both analog and digital signals DVI-I Dual Link (29 pin) . Supports both analog and digital signals, higher bandwidth DVI-A is used for analog signals (similar to VGA), while DVI-D is used for digital signals (similar to HDMI). DVI-I connectors can carry both analog and digital signals, but actual support depends on the device’s specifications. Single Link and Dual Link indicate bandwidth capacity, which affects maximum supported resolution. Typical limits are up to 1920 × 1080 @ 60 Hz for Single Link and up to 2560 × 1600 @ 60 Hz for Dual Link. However, actual resolution support depends on the capabilities of the connected devices, not just the connector type. To ensure compatibility, verify both the connector type and the signal support in the specifications of the source and display devices.

What DC barrel connector power plug types do StarTech.com products use, and what are their dimensions?
StarTech.com DC barrel connector plug types are defined in the “Plug Type” field of the technical specifications, using a letter code that specifies the connector’s outer diameter (OD) and inner diameter (ID) in millimeters for power adapter compatibility. Explanation: In StarTech.com technical specifications, the “Plug Type” field is a standardized identifier for the exact DC barrel connector size required to power a product. Each plug type is assigned a letter code that corresponds to a specific combination of outer diameter (OD) and inner diameter (ID), measured in millimeters. Common DC barrel plug type dimensions Plug Type OD ID A 2.35 mm 0.7 mm B 4.0 mm 1.7 mm C 4.75 mm 1.7 mm H 3.4 mm 1.3 mm L 5.0 mm 2.5 mm M 5.5 mm 2.1 mm N 5.5 mm 2.5 mm The DC barrel connector plug type must match both the outer diameter and inner diameter exactly. A mismatch between the StarTech.com product requirement and the power adapter connector can prevent proper fit or stable power delivery, which may result in device startup failure or intermittent operation. The plug type defines only the physical connector size. The plug type does not define electrical power requirements such as voltage, current, or polarity. The power adapter used with a StarTech.com product must match the product’s specified electrical requirements. Using an incompatible power adapter can cause device malfunction or permanent damage. This standardized DC barrel connector plug type system enables IT professionals and procurement teams to verify connector dimensions, ensure power adapter compatibility, standardize hardware deployments, and identify the correct replacement power supply for StarTech.com products.
