HDMI must run more than 15 meters and stutters

Above 5 to 10 meters passive HDMI starts losing signal. For 15 meters and more you need active solutions, HDBaseT over Cat6, fiber HDMI, or SDI conversion.

Try this first

  1. 1Measure the actual cable route, not line of sight, ceilings and conduits add length quickly.
  2. 2For 15 to 70 meters, an HDBaseT extender over Cat6 or Cat6a is common, fits in one Cat6 run.
  3. 3Above 70 meters, or at high resolution, fiber HDMI or SDI conversion works better.
  4. 4Watch EDID handshake, long runs sometimes need an EDID emulator otherwise the source gets no signal.
  5. 5For 4K at 60Hz check the extender against that spec, not every HDBaseT unit reliably handles 4K over distance.
  6. 6Document which extender is on which run, that saves diagnosis time during an incident.

When to bring us in

For wide signal distribution with many runs, an AV-over-IP architecture is sometimes cheaper than many extenders. Vectel can model both.
