Max HDMI length.
At the moment I have a SCART cable running from the PVR in the sitting
room to the TV in the kitchen, via a DA. Allows you to watch recorded things in the kitchen etc. The kitchen TV is on its last legs and I'm thinking I may have to update things to HDMI. It would need a cable of about 16 metres length. Is this ok? There appear to be passive splitters for a few quid - are they any good? Pukka DAs seem to range from about 20 -350 quid. ;-) -- *I'm planning to be spontaneous tomorrow * Dave Plowman London SW To e-mail, change noise into sound. |

This 20M cable came from 7 day shop, for what it's worth. I've noticed that as HDMI cables get longer they also get thicker - sequentially for the lengths I have of 2, 7, and 20M. It's unlikely that the currents involved are great enough to require larger conductors, so I presume that the internal core insulation has to be thicker on longer cables to keep the capacitance and inductance within limits. No experience of HDMI DA's though... Charles F |

I have used DVI over about 20m and that's the same signals as HDMI. I can't see why HDMI wouldn't also work over that distance as long as its a good cable. IIRC the cable came from cable universe but it was a while ago. |

The HDMI cable includes power supply so you can buy one that incliudes a tiny amplifier so increasing the distance you can transmit.

I would suspect a piece of string would work at 576i, but when it comes to 1080p I suspect many cables will fail over any distance. The quality of HDMI cables is extremely variable. Although not cheap, the Cat5e/Cat6 - HDMI extenders generally at least quote a performance. At least Ethernet cables are made to a specification. http://www.amazon.co.uk/HDMI-Extende.../dp/B00760ROUG You just need the Cat5e/6 cable, connectors and a set of pliers!! |

Donno, it's all a bit clever if you ask me. Mind you it seems pretty well thought out as "clever" systems go and more or less just works as one would expect. I don't know if the control side is a bus or something more akin to an ethernet LAN. -- Cheers Dave. |

You can crimp plugs onto cat5 cable but you need different plugs for stranded cable and solid cable. You can't really use IDC sockets with stranded cable if you want reliable connections. |

Inpractice on something that isn't going to plugged/unplugged, waggled about, pushed and pulled it probably doesn't matter that much. Pushing each of the eight contact blades into the wires and latching the cable grip might be tricky without the proper crimp tool. Toolsatan have one for £8.14. -- Cheers Dave. |
