Im not having issues just wondering why the video processor manufacturer tech rep is saying powered cables may be an issue
The HDMI chipsets in the device (receiver, tv, blu-ray, etc), any device that uses HDMI, will require the 5v to power the chipsets. The HDMI port will output 50mA for any active cable that it is connected to to power the chipsets that are in the connector end of the cable. If it's a passive cable, the 50mA output does nothing.
Spectra 7 is the current chipsets used in most active cables that are copper-based only (not fiber or hybrid fiber). If you have a cable run that is under 25', then you really don't need an active cable because data transfer between source and sink (HDMI 2.0) should work just fine. Over 25' then the recommendation is hybrid fiber which is an active cable and they usually have proprietary chipsets in the connector ends.
I don't understand about the "larger end" being connected to the pj from the processor. What exactly do you mean by processor (a receiver?) and what kind of cable is connected from it to the pj? Active HDMI cables have the same connectors on both end only they are usually labeled Source and Sink or TV to designate which end goes where because they have to be connected is a specific manner. Passive cables are not "directional" so they can be connected regardless of either end, and they are not labeled.
Projectors can have issues with active cables for the very reason I mentioned above, inconsistent current output at the HDMI port.
