How Do You Run a Display 75 Meters From Its PC?
June 4, 2019
With HDBaseT™: a transmitter at the PC and a receiver at the display, joined by a single standard CAT.5e Ethernet cable that bridges up to 75 m (246 ft) without loss of quality. It is the answer when a multimedia display has to go where there is no room for a PC to control it, and no room for a bundle of cables either. We supply our HDBaseT set, integrate it with the display, and support it from Ronkonkoma, New York.
What does HDBaseT carry over one cable?
Video, touch, audio, power and control together, so one cable replaces the bundle:
- Uncompressed HDMI video in Full HD, 2K or 4K.
- USB 2.0, for example to connect a touchscreen.
- Audio in all common formats.
- Power over Ethernet (PoE).
- Control signals, including CEC and RS-232/UART.
The transfer is uncompressed and lossless over the full distance, so the image at the display is the image the PC sends.
What does the set include?
A transmitter and a receiver. The installation adds a CAT.5e UTP Ethernet cable and a 12 V power supply, which powers the receiver directly and the transmitter over PoE. The set is cost-effective and easy to install, and it avoids the cable clutter of running separate video, USB, audio and control lines. Our HDBaseT long distance multimedia page has the overview.
Is HDBaseT an established standard?
Yes. HDBaseT is a global connectivity standard for transmitting high-resolution multimedia signals over long distances on a single cable, developed by well-known electronics manufacturers and widely used as a reliable industrial transfer standard. Building on it means the link uses standard network cabling rather than a proprietary one.
Tell us where the display has to go and where the PC can live, and we will take it from there. We recommend the display, controller and link, integrate them as one system, and stay with the project from first samples to series production, backed by our technical services. Our post on the role of TFT controllers in display technology covers the other end of the signal chain.
