Overview

The Cable Matters 400001-3x2 is a passive DVI to HDMI adapter designed to connect a DVI-D output from a PC or graphics card to an HDMI input on a monitor or TV. It features a DVI-D 24+1 male connector and an HDMI female connector, enabling one-way digital signal conversion. This adapter is extremely lightweight at 0.01 oz (approx. 0.28 g), making it easy to carry around without adding bulk to your cable setup. It's important to note that this adapter only supports digital DVI signals (DVI-D). It will not work with DVI-I (analog + digital) or DVI-A (analog) outputs. Also, audio is not transmitted because DVI lacks audio channels. The adapter is purely passive — no active chip means no additional power required, but also no signal re-timing or format conversion.

Connectivity & Compatibility

This adapter is strictly for DVI-D to HDMI conversion. Check your graphics card's DVI port: if it's DVI-I (which has four pins around the flat blade), you need a different adapter. For DVI-D (the slot has a flat blade with a cross-shaped pin arrangement), this adapter works perfectly. Connector: DVI-D 24+1 Male to HDMI 19-pin Female Signal Type: Digital only (passive) Max Resolution: Up to 1920×1200 (1080p) typical for single-link DVI Audio: Not supported HDCP: Pass-through if supported by the DVI source Direction: One-way (DVI to HDMI only) This adapter is not compatible with HDMI to DVI conversion. If you need that direction, look for a dedicated HDMI male to DVI female adapter. Also, dual-link DVI (high resolutions above 1920×1200) may not work as this adapter is designed for single-link bandwidth.

Product Info

Released around 2015, the Cable Matters 400001-3x2 remains a staple on and other retailers, typically priced between ¥1,000 and ¥2,000. It's an entry-level passive adapter. The warranty is generally 1 year (standard for Cable Matters accessories). The package includes only the adapter itself — no cable or manual. In terms of market positioning, this is a no-frills, budget-friendly solution. It's cheaper than active converters but may face compatibility issues with certain GPU/monitor combinations, especially when the HDMI sink expects a specific EDID or when the DVI source has limited bandwidth. For most standard 1080p setups, it works reliably.

Best Use Cases

Connecting legacy DVI cards to modern HDMI monitors: If you have an older graphics card (e.g., GTX 600 series or earlier) with only DVI outputs, this adapter lets you use a modern HDMI display without buying a new GPU. Simple and cost-effective. Utilizing spare DVI ports on a multi-monitor setup: If your main monitor uses DisplayPort and you have a spare DVI port on your GPU, this adapter can drive a secondary HDMI monitor. Great for extending your desktop without breaking the bank. * Not ideal for: Users who need audio over HDMI, 4K resolution, or reverse (HDMI→DVI) conversion. Also, if your GPU has a DVI-I port, this adapter will not fit. In those cases, consider an active converter or a different cable type.
