StarTech HDBOOST HDMI Signal Booster and Inline Repeater

Overview

The StarTech HDBOOST is an inline HDMI signal booster that extends a degraded HDMI signal up to 115 feet total — 82 feet on the input side and 33 feet on the output side — while holding full 1920x1080 at 60Hz. If you've run HDMI cable beyond 25–30 feet and hit the signal cliff (flickering, dropout, color shift), this is the fix: a compact repeater that re-clocks and amplifies the signal without adding a converter, balun, or active extender kit to your rack. No AV receiver required, no external power brick in most cases.

At 2.1 x 1.7 x 1.0 inches and 2.6 oz, the HDBOOST sits inline at the cable junction point — no shelf space consumed, no rack unit required. It draws power directly from the source device's HDMI port. If the source doesn't supply enough bus power, the optional SVUSBPOWER adapter (sold separately) handles it via USB, accepting 100–240V AC input and delivering 5V DC at 1A output.

Key Features

• 115-foot total HDMI reach (82 ft in + 33 ft out): Most passive HDMI cables start degrading around 25–30 feet. The HDBOOST pushes that to 115 feet total — enough to span a conference room, digital signage run, or AV presentation setup without a full HDBaseT infrastructure investment.
• 1920x1080 at 60Hz preserved end-to-end: Maintains full 1080p/60Hz through the boost, so fast-motion content (video, live feeds, presentations with animation) doesn't stutter or drop frames at the display end. Supported resolution ladder also includes 1680x1050, 1600x900, 1440x900, 1360x768, 1280x800, 1280x768, and 1280x720 — covers virtually every display standard in the field.
• 10-level signal equalization: Rather than a single fixed amplification level, the HDBOOST applies one of 10 equalization steps based on signal condition. This matters when cable quality or length varies between installs — the unit compensates dynamically instead of over-driving a short run or under-driving a long one.
• 7.1 surround audio pass-through: HDMI carries full 7.1 surround sound, and the HDBOOST passes that audio stream intact. Relevant for conference rooms with surround receivers or digital signage environments where the source outputs multi-channel audio.
• Bus-powered from HDMI source: In most configurations, no external power supply is needed — the booster draws from the HDMI port's native bus power. This keeps the install clean and eliminates a wall outlet dependency at the cable midpoint.
• Optional USB power via SVUSBPOWER (sold separately): When the source device doesn't supply adequate HDMI bus power — common with some media players and older switchers — the separate SVUSBPOWER adapter takes 100–240V AC and provides 5V DC at 1A output to keep the booster running reliably.
• Operating range 0°C to 70°C: Handles standard indoor environments comfortably. Not rated for uncontrolled outdoor or industrial thermal ranges, but covers AV closets, data center break-out areas, and conditioned conference rooms without issue.
• 2-year manufacturer warranty: StarTech backs the HDBOOST with a 2-year warranty — straightforward coverage for a passive signal path device.

Integration and Compatibility

The HDBOOST passes standard HDMI signals — it is not an HDBaseT transmitter, fiber extender, or IP streaming device. It works with any HDMI source and display within the supported resolution list. No drivers, no configuration, no software. Install inline on an existing HDMI cable run at the midpoint (or closer to the source end), connect power if needed, and the signal extends. It is not a splitter and does not support simultaneous multi-display output from a single input.

For longer runs beyond 115 feet, or for runs over Cat5e/Cat6 cabling, consider a dedicated HDMI extender or HDBaseT solution. For AV distribution across multiple displays, a separate matrix switcher or AV distribution amplifier would be the correct architecture. If you're integrating this into a broader digital signage or conference room AV system, verify that your source device provides adequate HDMI bus power before assuming the SVUSBPOWER adapter is unnecessary.

The HDBOOST is also relevant in surveillance monitoring stations where a DVR or NVR HDMI output needs to reach a wall-mounted display that's further than a standard cable can reliably drive — a common scenario in guard stations and operations centers.

Frequently Asked Questions

Q: Does the HDBOOST require an external power supply?

A: In most installs, no — it draws bus power directly from the HDMI source port. If the source device doesn't supply adequate bus power, the optional SVUSBPOWER adapter (sold separately) accepts 100–240V AC and outputs 5V DC at 1A to power the unit.

Q: What is the maximum cable run the HDBOOST supports?

A: The HDBOOST supports up to 82 feet on the input side and 33 feet on the output side, for a total reach of 115 feet. Cable quality affects real-world performance — use high-quality HDMI cables within those limits.

Q: Does the HDBOOST support 4K resolution?

A: No. The HDBOOST is rated to a maximum of 1920x1080 at 60Hz. It does not support 4K (3840x2160) or higher resolutions. If 4K is required, a different signal extender solution is needed.

Q: What audio formats does the HDBOOST support?

A: The HDBOOST passes HDMI audio including up to 7.1 surround sound. Audio is passed through as part of the HDMI signal — no separate audio connection is required.

Q: What is the warranty on the HDBOOST?

A: StarTech provides a 2-year manufacturer warranty on the HDBOOST.

Q: Can the HDBOOST split one HDMI source to multiple displays?

A: No. The HDBOOST is a signal repeater/booster, not a splitter. It extends one HDMI source to one display. For multi-display distribution, a separate HDMI splitter or distribution amplifier is required.

The HDBOOST comes up frequently in ops center and guard station builds where someone has already run HDMI cable to a wall-mount display and is hitting signal degradation past the 30-foot passive limit. The 10-level equalization is what sets this apart from a basic repeater — rather than applying a fixed boost that can introduce noise on shorter runs, the HDBOOST adjusts to the actual signal condition across the 82-foot input and 33-foot output segments.

Technical Highlights:

• 10-Level Equalization: Adapts signal correction to actual cable length and quality — prevents over-amplification on shorter runs while still cleaning up a marginal 82-foot input feed.
• 1080p/60Hz Maximum: Holds full frame rate at 1920x1080 — relevant for surveillance monitor outputs where dropped frames from a DVR HDMI port are the common failure mode at distance.
• Bus-Powered Operation: No outlet required at the cable midpoint in most installs — keeps ceiling and wall pathways clean, which matters in finished spaces where adding an outlet is not an option.

Deployment Considerations:

• Verify the HDMI source provides bus power before committing to a no-power-supply install — some NVRs and media players run low enough bus current that the SVUSBPOWER adapter becomes mandatory, not optional.
• The 115-foot total is a hard ceiling at 1080p — if the display run exceeds that or the project eventually requires 4K output, this unit is not the right path. Plan for HDBaseT or active fiber from the start on longer or future-proof runs.

The HDBOOST is the right call for a single-display guard station or operations room monitor run in the 50–115 foot range where you need a clean 1080p feed from an NVR or DVR HDMI output and don't want to introduce a full extender kit into the signal path.
