@RadarFR: There is a known problem with auto frame rate switching not working when receiver is HDCP 2.2 compliant and display is HDCP 1.4. Try a direct connection (without the receiver) to confirm the cause is having a mixed HDCP chain.

Also, I see somewhere that your projector supports HDCP 2.2 on HDMI 2 port, if that's correct then auto frame rate should work using it.
