Asked this question a couple of months ago on this post - http://www.geekzone.co.nz/forums.asp?forumid=34&topicid=41648&page_no=1#257342 – how to run 3 TV’s from 1 HDMI output - MySky?

So have just purchased a 4 way splitter - http://jaycar.co.nz/productView.asp?ID=AC1695&keywords=hdmi+splitter&form=KEYWORD  and it don’t work!

Each of the TV’s work fine when plugged direct into MySky HDMI – 13 meter cable run to each (after a lota drilling and blasting!!).

Any suggestions or do you think that have a faulty unit? The box had clearly been opened a few times.

Thanks

When does it stop working? When one is plugged in? Or all of them? Have you tested one port at a time, with the shortest cable length on both sides?

It states it is 1.2a compliant, does it need to be 1.3 ? (I do not know what MySky is)

13m's for each run is fair distance for hdmi. Could be signal loss based on the length of run and perhaps cable quality.

Does it work on the other tv's when only one or two 13m leads plugged into the unit?

You can check the box by using smaller cables to multiple tv's. (Obviously may not be easy to do depending on the tv's themselves).

HDMI splitting can be a bit touch and go. There's a document on it at rapallo basically saying you may have to shop around a bit to find one that successfully handles the hdcp handshake with all your gear.

There seems to be a consensus the around 50 foot (16/17 metres) is about as far as HDMI will go, but sticking a splitter in the way, may mean your 13 metre runs are just too far.

Check with a short length of cable.

Thanks troops
It has never worked – just got it today. The lights on the front corresponding to the 2 plugged in outputs do not light up.
The specs for the splitter unit says “can achieve long distance transmission of HDMI signal of more than 15 meters” and as said my 13 meter leads work fine to each TV when plugged into MySky individually.

I have a similar setup over 20 metres distance. Seems to work mostly but sometimes the shortest distance TV won't fire unless the longest distance one is turned on first. Seems to need to prove the signal can go the whole distance. I found it helped to bypass the receiver and take signal straight from Mysky to powered splitter to TV.  Murray at RappalloAv was extremely helpful in sorting me out.

Therein might be the problem, I'm using one of their one in two out splitters (1.3b) for Sky and it works great. If not, sounds like a dud splitter.

I believe HDCP is only available on HDMI ver 1.3 also.. and since Sky have HDCP would this have some effect (Though, I'd expect the MySky HDI would just output SD instead).

There is no fallback with their HDMI setup - if it fails the HDCP check you just get no picture.

Ah that explains it then.. so likely no HDCP being passed to your MySky so nothing being output.
