I've tried restarting all the devices involved, powering one on before the other, connecting the cable only after they're both on, etc. The two converters I tried both did that fine so I'm not worried about that being an issue. The converter needs to take the HDMI audio signal in and output it through a 3.5mm soundjack. If it is #1, can someone recommend a 3rd converter to try? I think one with a power supply would be more likely to work but I had trouble finding one on amazon. My ps4 has a video output format/setting that is incompatible with what the projector can take My projector is not configured to accept the input The converter is incompatible with the projector For that one second it displays the macbook hdmi out signal perfectly, it just doesn't stay connected. In this case, my laptop screen turns black for a second, then the resolution on my screen changes to XGA to mirror with the projector, then the projector displays the mirrored image of my laptop just fine, but after a moment it disconnects and starts the process over. However, it goes through a similar loop as with my PS4. When connecting with my laptop (macbook), the laptop correctly recognizes the external projector and its resolution, color profiles, etc. The manual says this code is displayed when 'a signal that the projector is not preset to re-ceive is received'. It checks to see if there's a connection, finds the PS4, tries to connect, then displays 'RGB NOT REG', then starts over. When connecting with the PS4, the projector goes through a loop. This converter is actice and almost works. I took this converter apart to see if there were any status LEDs when it was running, but I found none, nor did I see any visible disconnected wires or broken parts of the board. I suspect this converter is passive and didn't work because of that. The converter's sound output worked fine though. The projector did not recognize the input at all, both when connected to my computer and PS4. I understand that VGA uses an analog signal and HDMI carries a digital signal so the converter will have to be an active, not passive one. So I need a way to convert HDMI out to VGA in.

I'm trying to connect my PS4 to my Sharp PG-A20X projector.

Ps4 will not connect to projector hdmi
