StarTech DVIVGAMM6 DVI-A to VGA Analog Display Cable

Overview

The StarTech DVIVGAMM6 is a 6-foot (1.8m) passive DVI-A to VGA cable that bridges DVI analog outputs on PCs or Macs to standard VGA displays — flat panels, projectors, or monitors that still run a 15-pin HD D-Sub input. No active circuitry, no drivers, no external power: the signal path is purely passive, which means there is nothing to fail and nothing to configure. If your source has a DVI-A or dual-mode DVI port and your display takes VGA, this cable covers the connection cleanly.

This is a practical cable for AV integration racks, security monitoring stations, training rooms, or anywhere a legacy VGA display needs to stay in service alongside a newer DVI-equipped workstation or controller. The 6-foot length handles most desktop and rack-adjacent display runs without excess slack.

Key Features

• Passive DVI-A to VGA Conversion: No active electronics means zero latency introduced in the signal path and no compatibility quirks with display firmware. Plug in and it works — provided the source is outputting analog DVI (DVI-A or dual-mode DVI). Worth noting: this cable will not work with DVI-D (digital-only) ports, because there is no analog signal present on those connectors to pass through.
• 6.0 ft (1.8m) Cable Length: Long enough to reach a display on the same desk or a monitor shelf in a rack bay without strain on the connectors. Short enough to keep cable management tidy. For longer runs, you would need an active VGA extender downstream.
• 28 AWG Wire Gauge: Heavier gauge than the cheapest commodity cables — 28 AWG provides lower resistance per foot, which matters for signal integrity at the upper end of VGA's frequency range (UXGA and above). For standard 1080p or lower resolutions, the difference is marginal but not irrelevant in electrically noisy environments.
• Aluminum-Mylar Foil with Braid Shield: The dual-layer shielding — foil wrapping plus an outer braid — suppresses both high-frequency interference (handled by the foil) and lower-frequency EMI (handled by the braid). In a control room or rack environment where power cables, switching supplies, and RF sources are nearby, this shielding keeps the analog VGA image clean and free of banding or rolling noise.
• Nickel-Plated Connectors: Nickel plating resists oxidation better than bare copper, which matters on a cable that may be plugged and unplugged repeatedly or left connected in a humid environment. Connector corrosion is one of the most common causes of intermittent analog display issues.
• PVC Cable Jacket: The PVC outer jacket is flexible enough for typical routing around desk edges or through cable rings, and durable enough for permanent installation. It is not rated for in-wall or plenum runs — for those applications, a CL2/CL3 or plenum-rated cable is required.
• Passive Adapter Type: Passive design means full compatibility with any DVI-A or dual-mode DVI source without needing to check driver support, power draw, or operating system compatibility. It is also the reason this cable cannot convert DVI-D digital signals — passivity has limits.
• Lifetime Warranty: StarTech backs the DVIVGAMM6 with a lifetime warranty, which removes any long-term cost-of-ownership concern for a cable used in a fixed installation.

Integration and Compatibility

The DVIVGAMM6 connects any host with a DVI-A (17-pin) or dual-mode DVI output to any display with a standard 15-pin HD D-Sub (VGA) input. This covers a wide range of workstations, industrial PCs, embedded controllers, and KVM switches that expose a DVI port while driving legacy monitors or projectors on the display end. The cable also suits security and surveillance control stations where analog VGA monitors remain in service on newer digital workstations — a common scenario in phased hardware refresh cycles. It is not compatible with DVI-D sources, HDMI sources (without an adapter), or DisplayPort sources.

Frequently Asked Questions

Q: Will the DVIVGAMM6 work with a DVI-D port on my graphics card?

A: No. The DVIVGAMM6 is a passive cable and requires an analog DVI signal (DVI-A or dual-mode DVI). DVI-D ports carry digital signal only — there is no analog component to pass through, so this cable will not produce an image.

Q: Does the DVIVGAMM6 require drivers or software?

A: No. It is a fully passive cable with no active electronics. Plug it in and the display is recognized by the host system through standard analog VGA signaling — no drivers, no configuration.

Q: What is the maximum resolution supported?

A: StarTech does not publish a specific maximum resolution in the available evidence for this cable. VGA resolution limits are typically determined by the source and display hardware. The 28 AWG gauge and dual-layer shielding support clean analog signal transmission at common resolutions including 1080p and below over this 6-foot length.

Q: What is the warranty on the DVIVGAMM6?

A: The DVIVGAMM6 carries a lifetime warranty from StarTech.

Q: Can this cable be used for an in-wall or plenum installation?

A: No. The jacket material is standard PVC, which is not rated for in-wall or plenum runs. A CL2-, CL3-, or plenum-rated cable would be required for those installations.

Q: How does the shielding on the DVIVGAMM6 compare to unshielded VGA cables?

A: The DVIVGAMM6 uses aluminum-Mylar foil combined with a braid shield. Foil handles high-frequency interference and braid addresses lower-frequency EMI — a dual-layer approach that outperforms single-foil or unshielded cables in rack environments or anywhere power cables and switching electronics run nearby.

The detail that matters most on the DVIVGAMM6 is its dual-layer shield construction — aluminum-Mylar foil plus braid — which is what separates it from commodity grab-bag VGA cables in a working rack environment. I see integrators reach for cheap unshielded VGA cables in security control rooms all the time and then spend time troubleshooting rolling interference bars on operator monitors. Specifying the DVIVGAMM6 upfront removes that variable.

Technical Highlights:

• Dual-Layer EMI Shielding: Foil layer blocks high-frequency interference; outer braid suppresses lower-frequency EMI. Together they handle the noise profile of a typical rack with switching power supplies and structured cabling running parallel.
• 28 AWG Conductors: Lower resistance per foot than 30 AWG commodity cables — meaningful for signal integrity at the upper VGA frequency range, even over a 6-foot (1.8m) run.
• Nickel-Plated Connectors: Resists oxidation on both the DVI-A 17-pin and VGA 15-pin ends, reducing the risk of intermittent contact issues in installations where the cable is semi-permanent.

Deployment Considerations:

• Verify the source port before ordering: the DVIVGAMM6 requires DVI-A or dual-mode DVI. If the graphics card or workstation exposes DVI-D only, this cable will not work — no active conversion is happening here.
• PVC jacket only — do not route this cable inside walls or through air-handling plenums. For those paths, a rated cable is required regardless of the connector ends.

The DVIVGAMM6 is the right pick for a security operations center or monitoring station refresh where VGA displays are staying in service and workstations have been upgraded to DVI-A outputs — a phased replacement scenario where you need a clean, shielded bridge cable with a lifetime warranty and nothing to configure.
