The StarTech.com ST121WHDLR is a wireless HDMI transmitter-and-receiver kit for sending 1080p video up to 656 ft (200 m), making it suitable for digital signage, meeting spaces, and other setups where a remote display is useful and a long HDMI cable is impractical.
Recommended For
- AV installers and facilities teams sending a 1080p HDMI feed to a remote TV or projector when running a long cable or drilling through walls is impractical.
- Businesses setting up digital signage or trade-show demo stations that need to place a display away from its HDMI source without installing permanent video cabling.
- Meeting and training rooms sharing presentations from an HDMI-equipped computer to a room display, where plug-and-play hardware is preferable to installing projection software.
- Home AV users sending a 1080p HDMI source to a TV in a different location who want to avoid a long cable and can position the transmitter and receiver to maintain a usable wireless link.
Real-World Use Scenarios
- In a conference room, connect an HDMI laptop to a display across the room without routing a long cable; presenters can share slides or video on the remote screen at up to 1080p.
- For a digital-signage screen where running HDMI cabling is inconvenient, place the HDMI source near the content equipment and the display where it is most visible; the kit sends the video wirelessly between them.
- At a trade-show demo station, keep the media source separate from the display and avoid a long cable run across the booth; the receiver delivers the HDMI picture to the screen.
- When a TV or projector must sit far from an HDMI source and installing cable would mean drilling or extra wiring work, use the transmitter-and-receiver pair to send the picture wirelessly, with support up to 1080p.
- If the source device is placed near the transmitter but controlled from the display area, use the included IR extension to send remote-control commands back to the source.
