That makes sense, youāre not getting any āConnection Typeā listed for the HDMI ports.
Did someone run out of imagination naming the device āProjectorā in the EDID?
Hi Prashant. Here is the link to the cable I bought - the packaging says 100W power delivery and also Data Transfer. I have also tried using the USB-C cable supplied with the projector.
Same issue with all four USB-C ports on the MacBook Pro. This is the 16" 2019 model.
That cable is a no go for video (only āhigh-speedā USB 2.0 communications possible)ā¦ But the cable shipped with the PPM should work. What does your System Report say?
It does not list the Projector. It only refers to the internal LCD display.
OK, that means that it hasnāt successfully negotiated any video alt-mode, Iām curious how macOS was able to detect a display but not showing it in the systems reportā¦
Well, perhaps I have misunderstood. I see the projector listed as a connection option under the AirPlay icon in the menubar. But I guess it is seeing the projector over the wifi, not the cable.
@wernerj @Philips_Support_P. I have just tested the projector with the Philips cable and my work Dell laptop running Windows 10, and this connected instantly to the projector and worked fine. So clearly not a cable or projector hardware issue. I donāt have to configure anything on the MacBook - I should just plug it in and it should appear on the projector, right?
That would make sense, if it isnāt showing up under About this Mac / Displays then it hasnāt been recognized. I havenāt yet tested any HDMI alt-mode monitors/projectors on the 16" MBP, but it should work. I know that DP alt-mode works but I canāt verify HDMI.
Great, we know that the shipping cable and the projector works as intended but something might still be flakey with the 16" MBP support. You shouldnāt have to configure anything on the MBP.
Donāt even ask about EDIDā¦ all the chromaticity data and native white point etc. is all wrong. Since it needs to be burnt in, I left it for now. Probably future batches will improve it.
Yes it should just work on plugging it in. It should show up as Projector
in the airplay menu when connected by cable. The name over wifi is PPX620-nnn
with some 3 digit number.
What do you see in that menu after plugging it in?
What do you see in System Information? (option-click the apple logo on top left, then go to Graphics section)
I see the following. Systems information only shows the built-in display - projector is not mentioned
Iām curious if the Mac starts any video link whatsoever when you plug the PPM in. It should be visible in one of the /var/log/displaypolicy/displaypolicyd.* log files. Iām getting the following on alt-mode DP insertion but I have no idea how this is supposed to look like in HDMI mode:

@PEHowland Since the same cable works fine on another laptop, I think it must be a config issue on your MacBook.
How about trying one more thing ā connect the laptop and projector, then press HOME on the remote, go to Projector Settings > Input Source and choose USB-C.
This may somehow kickstart the Mac into detecting that a device is plugged in.
And I guess itās a dumb question, but are you sure youāre plugging the USBC cable into the VIDEO port on the projector (left side)? Does a green/amber LED light up on the projector when itās plugged?
@Philips_Support_P. Thank you. Yes, I have tried manually selecting USB-C as the input source, but this does not help (it switches back to Android after a few seconds of showing the green screen). I confirm I am using the USB-C video port and I have also noticed the green/amber light when it is plugged in.
I also just tried reinstalling MacOS by rebooting by machine and using Command-R to reinstall from the recovery disk. This has completed successfully, but the issue remains. I wondered whether the USB driver in the OS was corrupted somehow, but I guess not.
Neither of the two log files in /var/log/displaypolicy/ show any update when the projector is plugged in. My MacBook screen brightens and it pings when I plug in the cable, but thatās the only sign of recognition!
Iām banging my head against the wall butā¦ what happens when you plug it into the POWER port???
Well, the good thing is that the PPM and the supplied cable works in your Dell laptop, so we know that thereās no hardware issue with the PPM.
I have been trying to locate a true HDMI altmode USB-C to HDMI cable but those seems to be difficult to find. Most all of them use DP alt-mode and then convert DP to HDMI. I even tried the Apple Multi AV dongle, but that identifies as a separate dongle, neither DisplayPort or āDVI or HDMIā. Iām starting to believe that the 16" MBP isnāt supporting the HDMI alt-mode yet (which the 13" and 15" 2016-2018 MacBook Pro does as shown above).
Have you gotten the PPM to work in any 16" MacBook Pro @Philips_Support_P?
No display using the power port either, The only apparent difference is the power light does not show green.
