Ok, this is driving me nuts, hoping someone can help.
Trying to finish off cabling in my house renovation... Two runs of HDMI cable from sockets at top of wall next to projector mount, one is 10m the other is 15m.
On both cables, either end is connected to a HDMI module socket, into which further HDMI cables (as short as poss) connect to projector at one end, AV kit at other. Everything hidden behind walls.
The only things I have at hand to test are the PJ, an old Panasonic blu ray and a Mac mini.
Mac mini will output signal fine on both cable lengths, no matter how many extra connections are involved - ie. I can just connect the long cables directly to PJ and Mac bypassing the extra connections of the HDMI module sockets, or I can use the sockets and extra cable. All good. Happy me.
The Bluray however is being a bit more problematic. It's very temperamental and doing some weird things, fairly consistently. For example, connect it directly to the PJ via the 15m length and it's not happy, lost signal, U73 error etc. If I put a 4 port HDMI switch between PJ and cable then it's fine, but not if I put the switch between bluray and cable. Which strikes me as v odd. Seems fine on the 10m run but again a bit temperamental.
So, a couple of questions...
Is a 15m HDMI cable asking for trouble?
Or is it just that the HDMI signal from a bluray is very weak (or maybe just this one, it's a very budget BD35) - as the Mac mini is having no such trouble.
If that is the case, I will be adding HDMI equipped receiver in once house less like building site - will this output a stronger HDMI signal when fed from a bluray?
And/or do newer bluray players suffer from weak HDMI output?
Obviously I could just have cable ends sticking out of holes in wall, not such a problem at PJ end as will be using joinery to hide stuff a bit up there anyway, but at other end would like the neatness of the HDMI module sockets.
Hope this makes sense!
