Im having a problem getting my benq tk700sti to receive a 4k signal. I recently purchased a Playstation 5 that I have attached to an onkyo tx-rz610. It is in the 1st hdmi port with hdcp 2.2. I then have the hdmi out going to the projector itself in the input port. In the settings of rhe projector Itself I have it on "enhanced" so that it csn receive 4k signals. When I turn on the ps5 I will hear the music through the receiver, but the projector itself just keeps saying "signal searching" only when I turn the hdmi to "standard" in the projector itself can I see video. But this knocks it down to 1080p! Not why I spent over 2k....any suggestions!?
