Delivery and Shipping

Add some general information about your delivery and shipping policies.

This compact transmitter uses HDBaseT™ technology to extend your HDMI® signal up to 230 feet (70 meters) over a single CAT5e or CAT6 cable, to an HDBaseT display, projector or receiver (sold separately). The transmitter supports Ultra HD and Full HD video resolutions (4K and 1080p), with support for the accompanying digital 7.1 audio. Easy and discreet installation. For a simple and tidy installation, the HDBaseT transmitter features a small footprint and a built-in HDMI cable that connects directly to your video source, reducing clutter by eliminating the need for an HDMI cable at your local source. The transmitter is powered using USB, which means you can use a USB port on your source device to power the transmitter, which is perfect for extending from areas where power outlets may be limited. Use your own HDBaseT display, projector or receiver. The compact transmitter works seamlessly with other HDBaseT equipment, such as HDBaseT displays, projectors, and receivers. The simplicity and versatility of this compact transmitter make it the ideal 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. Seamless integration with your existing infrastructure. This transmitter 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 while also lowering your cost in cabling. Plus, because the HDBaseT transmitter uses standard network cables, it works with existing Ethernet infrastructures. This makes it the perfect solution for deploying digital signage in large buildings such as shopping centers, stadiums, schools or hospitals. Astonishing 4K picture quality from an impressive distance. With 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. HDBaseT uses an advanced method of modulation that enables you to distribute uncompressed HDMI audio and video along with additional signals, over a single Ethernet cable. Offering greater versatility than traditional HDMI extenders and longer distances than HDMI cables alone, HDBaseT is the clear choice for every integrator and system designer, because it can do so much, with just a single cable. The ST121HDBTD is backed by a 2-year StarTech.com warranty and free lifetime technical support. More from the Manufacturer. Installs easily and discreetly, with a compact transmitter that's USB powered and features a built-in HDMI cable. Maintains astonishing picture quality up to 130 feet away, with support for UltraHD 4K over non-proprietary CAT5e or CAT6 cabling. Ensures compatibility with your existing HDBaseT hardware, with HDCP compliance. Also supports HD video resolutions such as 1920x1200 or 1080p up to 230 ft. away. No software or drivers required with plug-and-play installation. Dolby® TrueHD, DTS-HD MA Audio.

Ethernet doesn't (CORRECTION: DOES) work on MacOs 12 Monterey

Purchased several in March 2022. After extensive work finding drivers for the ASIX network interface chip this unit has, it didn’t work. We tried on both M1- and Intel-based Macbooks. We've even gone to other sites and downloaded drivers from ASIX itself. Nothing worked. The system compatibility remarks on the product landing site were patently false. Until… Fast forward to June 2022. Re-downloaded new drivers from the Star-Tec website. While release notes on the site do not include MacOS 11 (Big Sur) or MacOS 12 (Monterey), the download file does include drivers for those OS versions. We followed the many steps to install and activate the driver, and it FINALLY works. It runs pretty hot, so I hope it lasts.

Gives extra ports.

Bought a new laptop and it did not have an ethernet port and this gives you that plus two high speed USB ports and an HDMI port provided that the USB C port has video capabilities, my laptop has an HDMI port so this is no big deal that I can't use the extra HDMI because my USB C port has no video capabilities. This is a basic unit and meets my needs so think about the needs you have before purchase. Note: If you purchase an USB C to USB 3.0 adapter you can use an USB 3.0 port in a pinch minus the video function.

Fantastic USB-C hub!

This dock satisfied my demands on XPS 15. If the USB-C cable was longer, that will be perfect.

Doesnt support DVI-DL (61hz+ screens or more)

Ive got a 144hz 1080p display and this adaptor will not output more than 60hz. Additionally, when using this adaptor it would only allow me to manage it using Intel HD (not the discrete nVidia card) Unsure if that last part would be the cause of the issue or the adaptor itself Got a laptop, Alienware 17 r4 with thunderbolt.
