That is because it is the cable almost every time.

Its annoying and I don't deal with it in any other room in the house without a processor, except VERY rarely. And in the rest of the house I run HDMI matrix, HDMI over Cat6, and multiple rooms with AVRs across numerous model years. Much more solid than the theater with the Radiance.
The Radiance Pro has very fast 4k edge rates. We have no control over these edge rates from the chip, and in fact have asked for more control but we were told it was not possible. The edge rate is the primary determinant for how high-speed a cable is needed. The customers who use the cables I recommend pretty much have few issues with cables. Not zero of course because this is after all HDMI.
The Radiance Pro HDMI 2.0 chips are autonomous and they control the HDMI interface. It is very hard for us to work around issues in these chips and more importantly in other devices. In the RadianceXS/XE/2XXX products we spent a great deal of time finding and working around HDMI issues in other devices. Issues like audio interrupts not implemented, timing requirements between actions that are not in the spec, requiring optional parameters when they should calculate them per the spec, etc. In the Pro we do not have the control over the HDMI 2.0 chips to add these work-arounds. So we are dependent on the chip vendor to find and fix most compatibility issues. Fortunately there are some compatibility issues we can address and have as they are discovered.
On a positive note, the latest Radiance Pro release (020117) has new microcode for the 18 GHz HDMI 2.0 input chip which does resolve a couple input side HDMI issues. It is not certain if these were issues in he the HDMI 2.0 18 GHz input chip or in the source devices that are being worked around, but they have been resolved. As the chip vendor provides new HDMI 2.0 input and output chip microcode updates we will include them in the the Radiance Pro updates once they pass our testing.
That latest release also fixes a couple of audio issues on the Radiance Pro output side.
One trick to help with power on order is to manually set the audio EDID and the 3D, HDR and Rec2020 modes in the Radiance Pro based on the audio processor and TV/projector's capabilities. This info is in the manual for the video (Global/video menu for HDR/2020 and output menu to 3D Options). However, for audio there is a special code to manually enable all HDMI audio modes sent back from the Pro to the sources. The code is MENU 0943 (and then a Save).
With these manual changes the Pro knows what audio modes and what video modes to report back to the sources even if the audio processor and/or TV/projector are turned off or even not connected. So these settings, in conjunction with current software releases, can help tame the power on order issue.
