This is becoming more of a problem as the new LED. 3D LED, TV processing requirements have to keep up with the Hollywood Movie Sound standards/Pictures.
Just in case you do not know, INTEL designed the HDCP secure authentication standard to connect compliant devices, cables and content together seamlessly under a specific backwards compatible standard. HDMI 1.3 or new 1.4.
Well you have guessed it !!!
Different manufacturers have equipment made in multiple locations and their distribution chains spread these over the world. Hence NO 2 boxes exhibit the same fault. (black picture or just a flashing source trying to connect graphic, that just will NOT sync and display)
Even changing the cables can have differing results!!
The long and the short of it is...., AT THIS TIME, unless you are able to try different boxes, cables with your primary display (projector, TV etc) you can NOT guarantee they will work, (a) First time (b) consistently.
I have changed many a configured system of inputs-outputs switches, cat5/6e extenders only to find that there is no common factor that eventually sorts this encryption issue out. Just box swapping seems to be the way. Of course you have to have a very understanding supplier!!!
There is also no way to monitor this process of encryption acquisition, since it all happens behind the scenes.
Even in point 2 point installations. IE, Sat/DVD box 1 cable ad then TV/Projector. Will not allays work.
IF ANY ONE HAS A MAGIC TOUCH OR INDEED A MANUFACTURER THAT ACTUALLY ACCEPTS THEY ARE SELLING UNDER DEVELOPED HDCP TESTED KIT I AM VERY INTERESTED.
This is a classic box development of new technology NOT soak tested with the same model numbers or various connection scenarios.
Sorry but keep on Swapping!!!
