HDMI Extender over Cat5e/6 - 70M (1080p) / 40M (4K@30Hz)
KanexPro EXT-HD50C compact HDMI extender TX+RX — 1080p up to 70M / 4K@30Hz up to 40M over single Cat5e/6. HDMI loop-out, selectable EDID copy, Dolby…
The KanexPro EXT-HD50C is a compact HDMI extender transmitter-receiver kit that extends HD signals up to 70 meters (230 ft.) at 1080p, or 40 meters at 4K@30Hz, over a single Cat5e/6 cable. The transmitter includes an HDMI loop-out for local monitoring or cascading to additional extender units. A selectable EDID copy function lets the TX read EDID from either the local loop-out display or the remote receiver display, ensuring the source always outputs at the correct resolution. Dolby TrueHD, DTS-HD Master Audio, and PCM 7.1 audio pass-through are supported. Bi-directional IR control with included blaster kits, ultra-slim 16.5mm chassis, and KanexPro's 3-year warranty complete the package. Applications: Digital signage, conference rooms, education, healthcare, residential multi-room, and cascaded multi-display installations.

Questions
- What is the maximum resolution and bandwidth of the EXT-HD50C?
- The EXT-HD50C is HDMI 1.4 / HDCP 1.4 compliant with 10.2Gbps bandwidth, supporting up to 4K@30Hz (4:2:0) or 1080p@60Hz.
- What are the maximum distances by cable and resolution?
- Over Cat6: 70M (230 ft.) at 1080p@60Hz or 40M (131 ft.) at 4K@30Hz. Over Cat5e: 60M (197 ft.) at 1080p@60Hz or 35M (115 ft.) at 4K@30Hz.
- How does the HDMI loop-out support cascading?
- The TX HDMI LOOP OUT can drive a local confidence monitor or connect to a second EXT-HD50C TX to extend to additional rooms.
- How do I select the correct EDID mode?
- Use the EDID mode switch on the TX to choose Local (reads the loop-out display EDID) or Remote (reads the RX display EDID), then power-cycle both units to apply the change.
- What cable is required?
- Cat5e or Cat6 cable, STP recommended with proper grounding; do not exceed the maximum distance for the resolution in use, and keep the cable away from power lines.
- What are the unit dimensions and weight?
- The TX and RX chassis measures 3.13 x 2.72 x 0.65 in (79.5 x 69 x 16.5mm); TX weighs 0.29 lb (132g) and RX weighs 0.29 lb (130g).
- Image quality is degraded or there is no signal at maximum distance. What should I check?
- Use Cat6 STP with proper grounding, avoid parallel runs with power cables, verify connectors are fully seated, reduce cable length if possible, and try switching EDID mode.
- The source outputs the wrong resolution. What should I check?
- Switch the EDID mode on the TX to match the target display: Remote reads the RX display EDID, Local reads the loop-out display EDID. Power-cycle both units after changing.
- What installs is the EXT-HD50C suited for?
- Its dual reach of 70M at 1080p or 40M at 4K@30Hz over Cat6, plus a loop-out for local monitoring or cascading to a second unit, fits multi-room or long-run installs where extended distance matters more than native 4K reach.
- Why does distance vary by resolution and cable grade?
- The higher-bandwidth 4K@30Hz signal degrades over distance faster than 1080p, so reach drops from 70M/60M (1080p, Cat6/Cat5e) to 40M/35M (4K@30Hz, Cat6/Cat5e); choosing Cat6 over Cat5e extends both figures.
