We just received a Cisco CHS 435HDC set-top box from Verizon and replaced the Direct TV Set-top box that was installed. Video was displaying fine with the Direct TV box, but when we hooked everything up to the CHS box we only got a blue screen to display. We switched the HDMI that was connected to the CHS box and plugged it into a laptop and then everything displayed fine again.
We ran a coax cable to the TV , not through the CHS box, and everything displayed fine. We tried resetting the box, made sure everything was plugged in, etc. etc.
We have a HDMI through Ethernet extender going from the box to the TV and I have confirmed that both, extender and TV, use HDCP 2.2 and was wondering if the CHS uses an older version of HDCP that isn't compatible with this version. And if so, do we have to get a converter for it? I've also read that HDMI splitters can help fix the problem?
