    Guys,

    After shellin' out 30 quid on a Cablesson 15m HDMI wire and finding it can't hack it when reviewees said they experienced no issues with games and HD content i'm :cool: meh.

    So do we have to spend 200? Or get a crappy boost?

    Thanks

    Adey

    cheap crap from the local computer market :)

    thankfully my TV's native res matches what the cable can do, so it worked out. gives me heaps of green artifacts if i use it on my 24" at 1080p tho.

    Looking good. Either i take a chance and buy extender or try a higher rating (24awg) i think it was. My thought is extender will di itbut it's not my first choice. It may also be the only viable solution over that distance.

    15m is roughly 50ft, so keep that in mind. 25ft and 35ft cables aren't usually an issue, but 50ft will be.

    I'm not really surprised that the HDMI cable can't transmit the signal that far. However, I am surprised that they can get away with claiming it can, which makes it fraud. :shadedshu

    I read an article a while back on why HDMI cables can't be too long. It seems odd when a bog standard network cable can be upto 100m and still work just fine doesn't it?

    The article was quite long and detailed and I don't have the link for it, but the basic story is that line length wasn't considered when the HDMI spec was being designed, so signal degradation is quite severe over long lengths.

    It's true that cheapie HDMI cables are fine for short distances up to 3m or so, but not true for long distances.

    That's pretty creative breaking an HDMI signal into two 4-pair CAT cables.

    CAT6 especially has tougher requirements for each individual pair compared to HDMI. I'd trust a 100' run of CAT6 over HDMI any day.

    It's also a boon to those that are already CAT6 hardwired. I'd be able to keep my server upstairs, and still use it as an HTPC downstairs.

    Monoprice also has 22awg HDMI cables: http://www.monoprice.com/products/subdepartment.asp?c_id=102&cp_id=10240#1024001 Don't know where they ship to tho.

    Yep, I believe those adapters support up to the HDMI 1.2 standard. Which should be fine for 1080p with 5.1 audio.
