StarTech MXT105HQ High-Resolution VGA Extension Cable

Overview

The StarTech MXT105HQ is a 15-foot VGA extension cable built to move a monitor, projector, or KVM console further from its host without introducing signal loss that shows up as ghosting or blurred text. It's a coupler-style extension — HD15 VGA male-style connector on both Connector A and Connector B — designed to plug straight in between an existing VGA cable and its display, adding reach without forcing a full recabling job. For integrators handling conference rooms, control rooms, or point-of-sale kiosks where the monitor sits father from the source than the stock cable allows, the MXT105HQ is a straightforward fix rather than a redesign.

Key Features

• 15 ft (4.6 m) length: Covers the gap between a wall-mounted monitor and a rack-mounted or desk-mounted source without daisy-chaining multiple short cables, which is where most VGA signal degradation actually starts.
• 75 Ohm impedance: Matched impedance keeps the analog signal from reflecting back on itself over distance — this is the spec that determines whether your extended run stays clean or starts showing faint double-edges on text and fine lines.
• 1024x768 max resolution support: Rated for standard XGA output, which lines up with the reality of most VGA-era displays still in service on digital signage, POS terminals, and legacy conference room projectors.
• 15-pin High Density D-Sub connectors (both ends): Standard VGA HD15 on Connector A and Connector B means no adapters needed — it drops into an existing VGA run as a straight extension.
• 0.3 in (8.8 mm) cable OD: A moderately thick, shielded jacket that resists crushing under floor mats or behind furniture better than a thin unshielded cable, without being so bulky it fights you in a cable channel.
• Compact cross-section (1.3 in W x 0.6 in H): The connector housings stay low-profile enough to sit behind a wall plate or in a shallow AV credenza without protruding.
• 1.2 lb (0.5 kg) total weight: Light enough that it won't stress a wall-plate connector or add strain to a monitor arm cable run over time.

Integration & Compatibility

Because the MXT105HQ uses standard VGA HD15 connectors on both ends, it works as a pass-through extension for any VGA source — desktop graphics cards, KVM extenders, digital signage players — feeding any VGA-input display. It's a straightforward addition to a broader AV cabling deployment, and pairs naturally with cable management accessories when routing the extra 15 feet through a rack or wall channel. If you're planning a larger monitor rollout, it's worth reviewing a structured cabling and power planning guide before standardizing on any single cable length across a site — mixing extension lengths across a building often creates more troubleshooting overhead than it saves. The MXT105HQ is stocked alongside the broader StarTech catalog of connectivity products for buyers standardizing on one cable vendor across a facility, and fits within a general cables and connectivity category for procurement teams sourcing multiple accessory types on one order.

Frequently Asked Questions

Q: What's the maximum cable run length for the MXT105HQ?

A: The MXT105HQ itself is a 15 ft (4.6 m) extension. It's designed to extend an existing VGA cable run by that additional length.

Q: What resolution does the MXT105HQ support?

A: It's rated for up to 1024x768 resolution.

Q: Does the MXT105HQ need a separate adapter to connect to a standard VGA cable?

A: No. Both Connector A and Connector B are standard 15-pin High Density D-Sub VGA connectors, so it connects directly to existing VGA cabling.

Q: How thick is the MXT105HQ cable, and will it fit in a wall channel?

A: The cable outer diameter is 0.3 in (8.8 mm), which fits most standard cable channels and raceways.

Q: How much does the MXT105HQ weigh?

A: 1.2 lb (0.5 kg).

Karl Wilson

The spec that matters most on the MXT105HQ is the 75 Ohm impedance rating — that's what keeps a 15 ft extension from turning into a soft, ghosted image on the far end. I've seen integrators grab a generic extension cable for a VGA run and end up chasing a fuzzy-text complaint that was really an impedance mismatch the whole time.

Technical Highlights:

• 75 Ohm impedance: matched to standard VGA signal specs, minimizing reflection loss across the full 15 ft run.
• 1024x768 max resolution: appropriate for the XGA-class displays and projectors still common in legacy AV and POS installs — don't expect this cable to carry higher-res analog signals cleanly.
• 0.3 in (8.8 mm) OD, 1.2 lb weight: substantial enough shielding for the length without being unwieldy to route through a wall plate or raceway.

Deployment Considerations:

• This is an extension, not a replacement cable — it adds 15 ft to whatever VGA cable is already in place, so measure the total combined run against your resolution needs before ordering.
• VGA is an analog signal, so even with matched impedance, stacking multiple extensions end-to-end will degrade image quality faster than a single continuous run — keep it to one MXT105HQ per connection where possible.

Right fit for a conference room or lobby display retrofit where the monitor got moved farther from the source than the original VGA cable reaches — plug the MXT105HQ in rather than re-pulling cable through the wall.
