Hi

I am setting up a new TV and am planning to use an HDMI splitter (amplified) to send the HDMI to two TV's. One will require a 15M of HDMI cable and another 10M.
It has been suggested that all should work well with the splitter as long as I use decent HDMI cable.. (should be at least 24AWG)

Looking around there seems to be a variety of HDMI cables (and prices).. is the AWG rating the primary thing to take into account?
Rapallo sell the Redmere cable which are directional. Just wondering how these would compare to the high speed HDMI cables they also sell.

Also have a secondary query re patch leads.

I was planning on running the long lengths of cable into an appropriate AV wall plate. So it was all nice and neat and I would just run a short patch lead from the wall to the TV etc. Obviously adds just a little more to the length.. but presumably no major issues with this approach?

- thanks

I bought the cheapest one on trademe 15M no problems.

you should be worried about longevity rather than whether it will work.

yes it will work (I am not sure about 3D I think it needs 1.4x) but how long will it last?

someone else should be able to add to it

over 10 meter *can* work but not all equipment will like it using standard cables. CDL NZ (and their resellers like pb tech) sell Dynamix (ie cheap) branded hmdi cables that are far better at long distances as they have a passive extender built into the display end of the cable for anything 15 meters and over we used one to replace a 20meter cable that was always problematic with an active hdmi extender to a projector.

More info here.

This shouldn't cause any problems at all.

Just thought I would point out that there are still many many cables on trademe that arent the best of HDMI (high speed they call it, ugh at marketing types), they will only reliably do 720p or 1080i, if you read the listings they dont mention 1080p60 so they are still within what they say they will do so you cant go sending them back for being broken since they only have to do 1080i60 for the lower spec (not high speed) cables.

Adding short cables and wall plate couplers can cause issues, so be prepared to not have them if you suddenly find the display is not detected half the time or you get sparkles or lines blanking out etc, that is dont measure the cable and not allow for a bit extra at the display end if you need it.
