i too am receiving a "no signal" message from one of my TVs. I have a rocketfish 4k ultra hdmi 2 port spitter. Interestingly, somehow I was abe to (one time) trick the unit to handshake. Now reading this I think the dreaded HCDA handshake issue is occuring. I have a samsung ln32c350d1 unit offering up the no signal message. and an older panasonic tc-p46c2 not having a signal problem. Help??!!
