Wonder if anybody out there can help... Is it possible to split a HDMI signal via a splitter box with no degradation of quality? Basically, wondering if I could split the Shy HD signal into two TV's...

Thanks

Yup, but not cheap - www.clearly-av.co.uk/EXT-HDMI-142.html?gclid=CILRkoXit4sCFSoMQgoddynw1w is one that I have heard ok things about.

Yeah, I've just ran a few searches and they range from £70 - £300... makes you wonder about quality.

Basically, toying with the idea of two Plasma's on the ground floor and am thinking to either splitting the signal to either the run the same image to both sets, or switching the signal for either or. The latter option is cheaper, but I'd prefer the former... Not cheap though.

If I were you I'd replace your Yamaha amp with one that has several DVI/HDMI inputs, then you can use the amp as a switcher and Robert's your mother's brother.

Then you get a whizzy new amp for not much more cash than some of those switch boxes cost alone. And you can flog your old one as well, or keep it for the "games room"

Mmmm, quick search says that you can get amps with multiple HDMI inputs, but with only one output... I need at least 1 in, two out.

Hopefully I'll be proved wrong.

I never read your post properly to see you wanted to split outputs not inputs.

The specs for HDMI doen't define a maximum cable length but do specify a minimum cable quality. Presumably this means if a splitter device meets the required specs for HDMI quality then it will cause no signal degradation.

Why do you want to split the HDMI signal anyway?

Less than £20 here worth a punt at that price I'd say.

Looks good and I think it'd be ok - I've not kept up with HDMI for various reasons, but I'm not sure about internal resonance with these signals - I'm sure these days the spec designers would tune it out all together, but that's the only thing I can think of being an issue with a splitter like that.

As said, for 20 quid it's worth a punt

I've been looking into HDMI cabling and I'm going to give the £20er a go and see if there's any noticable drop in quality.

[rantmode]right, now I've also been looking into the prices of a 10m cable and they range from £50 - £200!!!! Now, as keen an eye/ear as I have, does anybody out there think that the output would be four times as good with the top dog cable?!! Especially considering the source would be Sky HD... [/rantmode]

I reckon all this expensive cable is snake oil. Buy the cheap ones.

If you want to run SkyHD to two TV's you don't need a splitter.

SkyHD has HDMI and component outputs, so you just run HDMI to one TV and Component to the other. Both TV's get HD the only thing is that the TV connected via component will require auido cable too (which the SkyHD box also outputs).

You can even have both TV's receive a signal at the same time yes

This is what I do, component to my TV and HDMI to my projector

As for cable quality, from what i've read, for short runs cheap cables are as good as any, providing they are properly terminated.

However for HDMI/ DVI runs of 10-20 meters it pays to spend a bit more. I think there is a spec which states how long the cable should be before you require a repeater (50m maybe?). I got a 10 meter HDMI and I paid about £60 i think, the quality is fantastic but I haven't used any other cables, either more expensive or cheaper to see what (if any) the differences would be.

I got mine from www.tvcables.co.uk (seem good value).
