The extender supports Ultra HD and Full HD video resolutions (4K and 1080p), with support for the accompanying digital 7.1 audio.Easy and discreet installationFor a simple and tidy installation, the transmitter in this HDBaseT extender kit features a small footprint and a built-in HDMI cable that connects directly to your video source, reducing clutter by eliminating the need for a local HDMI cable.You can power the transmitter using a USB port on your source device, which makes it easier to install in areas where power outlets may be limited. Mounting hardware is also included for the receiver ensuring a discreet, professional installation. The simplicity and versatility of this compact transmitter make it a convenient solution for transmitting an HDBaseT signal to a boardroom or classroom projector, enabling presenters in your office to quickly connect their laptop computer and share presentations or data sheets.The simplicity and versatility of this video extender make it the ideal solution for digital signage applications in large buildings such as shopping centers, stadiums, schools, and hospitals.Seamless integration with your existing infrastructureThe kit extends HDMI and 7.1 surround sound over a single cable, unlike some HDMI extenders that require two cables and only offer minimal audio support. Extending HDMI with one cable reduces potential failure points and also lowers your cabling costs. Plus, because the HDBaseT extender kit uses standard CAT5e, CAT6 or CAT7 cables, it works with existing Ethernet infrastructure that's already built into large commercial buildings such shopping centers, stadiums, schools, and hospitals, making it the perfect solution for deploying digital signage.Astonishing 4K picture quality from an impressive distanceWith high-quality HDMI cables beginning signal degradation at 30 feet, it can be difficult to maintain the brilliance of 4K video even at shorter distances. But with HDBaseT you'll be amazed at how your Ultra HD picture, four times the resolution of high-definition 1080p, is just as brilliant, even at distances up to 130 feet from your video source.Even if you're not running 4K, HDBaseT supports High-Definition 1080p and lower resolutions at even greater distances, up to 230 feet from your source, giving you piece of mind to know that this extender will comfortably work with any HDMI video source and display.What is HDBaseT?HDBaseT is a standardized, zero-latency, video distribution technology that's revolutionizing HDMI distribution.
