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. ;-)

http://en.wikipedia.org/wiki/HDMI

I've got one 20 metre HDMI cable (study PC to living room TV) which seems
fine - picture always locks when selected as fast as signals with shorter
length cables. 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...

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. Digital
signalso no degradation.

Last monitor I bought has what looks like an HDMI connector in the
picture if you don't look closely, but is actually a Display Port
connector, which won't quite mate with HDMI. Fortunately, it was
the DVI connection I mostly needed, although HDMI would have been
useful for a raspberry pi connection. (I only found this out about
a year after buying the monitor, when I tried to connect a raspberry
pi to it.)

HDMI has various data rates according to the resolution.

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.

You just need the Cat5e/6 cable, connectors and a set of pliers!!

Yes I suppose so. Which makes you wonder why they are sold. I'll have to

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.

You can get HDMI-DisplayPort adaptors very cheaply - my laptop needs one.

An HDMI to DVI converter costs pennies - HDMI is a superset of DVI, so
ignoring HDCP content and audio, HDMI and DVI are directly compatible
and simply need an adapter for the connectors. The only catch is whether
your monitor can sync with the HDMI signal - one of mine (NEC multisync)
does for my RPi, but the other (Sony) doesn't.

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.

Yes but ...

Ideally you need the right plug for the cable. Ones for soild core
(installation) have an offset three pronged fork arrangement of the
insulation piercing contact. Ones for stranded (patch) are just a row
of aligned points. 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.
