Startech HDBOOST 35m HDMI Signal Extender/Booster – 1080p

Startech HDBOOST Description

Startech HDBOOST HDMI signal booster lets you increase the signal strength of your HDMI video source so you can connect an HDMI display up to 115 ft. (35 m) away, using standard HDMI cables. You can place the booster inline between two HDMI cables, up to 82 ft. in length at the video input, and up to 33 ft. in length at the video output.

HDMI booster extends a video source to a display

Discreet installation

With its small form factor, the HDMI booster is easy to hide, for a discreet installation. You don’t need an external power adapter to operate the signal booster, and it includes mounting hardware, so installing it is hassle-free. By extending your video signal using standard HDMI cables, the HDMI booster is a cost-effective alternative to more expensive HDMI extension systems that require the installation of CAT5 or CAT6 cabling infrastructure.

Compatible with varying distances

The HDMI booster features an equalization switch with ten different levels. The equalization switch lets you adjust the amplification of your HDMI signal based on the distance of your cables, so that you can ensure your HDMI signal will be perfect even at distances up to 115 ft. (35 m). The booster is perfect for boardrooms, offices or classrooms that may require varying distances depending on the room size.

Maintains high-definition video signals

When extending HDMI over long distances using standard video cabling, higher resolutions can become unavailable. Using the HDMI signal booster ensures that you’ll still be able to depend on high-definition resolutions up to 1080p at 60Hz.

The HDBOOST is backed by a 2-year warranty and free lifetime technical support.


  • Avoid running network cabling to extend video signals, by using this booster with standard HDMI cabling
  • Boost the signal strength of your HDMI video signals for classroom, office or boardroom displays
