HDMI problems

I have a Sherbourn PT-7030 going to a Samsung UN60KU6300FXZA through a 

Transformative Engineering TE  HDS-42AVR HDMI switcher. About 25% of the time while switching sources (DirectTV and Roku) the HDMI handshake will not complete. Unless I turn everything off and back on again.  Using the Transformative Engineering TE HDS-42AVR HDMI switcher because the Samsung TV has only one 4K input.

Does anyone have any experience with the TE HDS-42AVR?  I’ve made sure I have high speed HDMI cables (Blue Jean Cables)

HDMI handshake is a nightmare for sure especially when a switcher is involved  - I'd try turning the HDMI controls off on all devices(sources and TV)and see if the signal passes through.

Sounds counter intuitive but I wouldn't be surprised if it solves the problem for you.
HDMI sucks... most of the reason I took all of it out of my primary listening system. It’s always a pain. I’m constantly rebooting/resetting our bedroom ROKU because the handshake fails one way or another. Drives me nuts. And BJ’s cables are great, but the interface overall is just bad...
