StarTech DPMDPHD2HD 2-in-1 DisplayPort/Mini-DisplayPort to HDMI Adapter

Overview

The StarTech DPMDPHD2HD is a passive video adapter that solves a specific integration headache: a source device with DisplayPort or Mini-DisplayPort output that needs to feed an HDMI-only display, extender, or capture input. Rather than stocking two separate adapters, DPMDPHD2HD covers both connector types on the source side and outputs standard HDMI at up to 4K resolution at 30Hz. For control rooms, digital signage installs, and conference room retrofits where the source hardware varies by workstation but the display infrastructure is standardized on HDMI, that flexibility cuts the number of SKUs a technician has to carry on a service call.

Key Features

• Dual Source Connector (DisplayPort + Mini-DisplayPort): One adapter body accepts either a full-size DisplayPort or Mini-DisplayPort source, so a single stocked part covers laptops, workstations, and desktops with mixed video outputs — no need to guess which adapter a given machine needs before the truck rolls.
• 4K at 30Hz Output: Passes 4K resolution to an HDMI display or downstream extender, which matters if you're feeding a lobby video wall or a monitoring station display where text and camera feeds need to stay legible at native resolution.
• Passive Adapter Design: No signal processing chip inside, which means no driver dependency and one less active component that can fail mid-deployment. It also keeps the unit small and low-profile behind a display or in a tight AV rack.
• USB-Powered: Draws power from a USB port rather than requiring a separate power brick or external supply — one less cable to route and one less power outlet to find near the install point.
• 6.6 ft (2 m) Cable Length: Long enough to reach from a desktop tower to a wall-mounted display or from a rack-mounted source to a patch point without a coupler, reducing the number of joints in the signal path.
• Compact Footprint: At 2.4 in wide, 0.6 in tall, and 7.9 oz, DPMDPHD2HD tucks behind a monitor or inside a shallow AV enclosure without adding meaningful bulk to a cable run.
• Wide Operating Temperature Range (0C to 60C): Rated for standard indoor commercial environments — equipment closets, control rooms, and non-climate-critical AV racks — without needing a hardened or industrial variant.
• Single Display Output: Built for one HDMI display per adapter, which keeps the signal path simple and predictable — this is not a splitter or a multi-display hub.

Integration & Compatibility

DPMDPHD2HD is a straightforward drop-in for any workstation, video wall controller, or signage player outputting DisplayPort or Mini-DisplayPort where the downstream device — display, HDMI matrix switcher, or capture card — only accepts HDMI. Because it's passive and USB-powered rather than relying on active signal conversion electronics, it integrates cleanly into existing PoE switch and AV rack builds without adding a separate power drop. If you're standardizing a facility's video distribution around HDMI-based network video recorders or monitoring walls, pairing DPMDPHD2HD with a broader cable and connectivity plan is worth reviewing against a PoE planning guide before a multi-room rollout. For DisplayPort-heavy environments, browse the full StarTech catalog for matching cable lengths and connector variants, and check the cables and adapters category for extension or coupler options if your run exceeds the included 6.6 ft length.

Frequently Asked Questions

Q: Does the DPMDPHD2HD work with both DisplayPort and Mini-DisplayPort sources?

A: Yes. It accepts either a DisplayPort or Mini-DisplayPort connector on the source side and outputs standard HDMI, per the Connector A specification listing both.

Q: What's the maximum resolution supported?

A: DPMDPHD2HD supports 4K resolution at 30Hz.

Q: Does this adapter need external power?

A: No. It's USB-powered, drawing power from a USB port rather than requiring a separate power supply.

Q: How long is the cable?

A: The cable measures 6.6 ft (2 m) from connector to connector.

Q: What's the warranty on the DPMDPHD2HD?

A: DPMDPHD2HD carries a 2-year manufacturer warranty.

Q: Can this adapter drive more than one display?

A: No. It supports one HDMI display output per unit.

James Everett

I get asked about mixed-source AV racks constantly, and the DPMDPHD2HD is the adapter I point people to when a workstation refresh brings in a mix of full-size DisplayPort and Mini-DisplayPort machines feeding the same HDMI display wall. Having both connector types on one adapter body means I'm not stocking two part numbers for what's functionally the same job.

Technical Highlights:

• 4K at 30Hz output: Enough resolution headroom for a monitoring station or signage display without needing an active converter — passive designs like this one keep the signal path simple.
• USB-powered, passive design: No external power brick, no driver install, one less failure point in a rack that already has too many cables.
• 6.6 ft (2 m) cable: Long enough to route from a desktop or rack unit to a nearby display or patch panel without needing a coupler joint in the middle of the run.

Deployment Considerations:

• Because it's passive, don't expect this to do audio embedding or signal boosting beyond what the DisplayPort source already outputs — if your run needs active amplification over a long distance, this isn't that adapter.
• This is a single-display adapter (Number of Displays Supported: 1) — if you're building a multi-monitor signage array, you'll need one DPMDPHD2HD per display, not a splitter setup.

This is the adapter I'd specify for a conference room AV retrofit where the room's laptops are a mix of Dell (DisplayPort) and older MacBook (Mini-DisplayPort) units, all feeding one HDMI-input projector or display — one adapter model covers every laptop that walks in the door.
