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)
